Definitions
- the present application relates to the field of communication technology, and in particular to a communication method, device, and system.
- 802.11bf is a next-generation wireless standard focused on sensing passive objects (i.e., targets without any devices).
- 802.11bf includes two broad categories: low-frequency (e.g., below 7 GHz, primarily implemented using 802.11ac, 802.11ax, 802.11be, 802.11bn, and future generations) and high-frequency (e.g., greater than or equal to 60 GHz, primarily implemented using 802.11ad, 802.11ay, and future generations).
- sensing devices can estimate parameters (such as speed, distance, and angle) of perceived targets based on received signals.
- the estimated results can be used for subsequent motion/behavior recognition.
- the high-frequency and low-frequency sensing processes are performed independently, meaning each has its own independent and complete sensing process.

Description
本申请要求在2024年04月15日提交中国国家知识产权局、申请号为202410458817.7的中国专利申请的优先权,发明名称为“通信方法、装置及系统”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。This application claims priority to the Chinese patent application with application number 202410458817.7 filed with the State Intellectual Property Office of China on April 15, 2024, and priority to the Chinese patent application with the invention name “Communication Method, Device and System”, all contents of which are incorporated by reference into this application.
本申请涉及通信技术领域,尤其涉及一种通信方法、装置及系统。The present application relates to the field of communication technology, and in particular to a communication method, device, and system.
电气与电子工程师协会(institute of electrical and electronics engineers,IEEE)802.11bf是关注无源物体(如目标不携带任何设备)感知的新一代无线标准。802.11bf标准中包括低频(如低于7吉赫(sub7GHz),实现方式主要依托802.11ac,802.11ax,802.11be,802.11bn及下一代标准等)和高频(如大于或等于60GHz,实现方式主要依托802.11ad,802.11ay及下一代标准等)两个大类标准。The Institute of Electrical and Electronics Engineers (IEEE) 802.11bf is a next-generation wireless standard focused on sensing passive objects (i.e., targets without any devices). 802.11bf includes two broad categories: low-frequency (e.g., below 7 GHz, primarily implemented using 802.11ac, 802.11ax, 802.11be, 802.11bn, and future generations) and high-frequency (e.g., greater than or equal to 60 GHz, primarily implemented using 802.11ad, 802.11ay, and future generations).
在802.11bf标准中,感知装置可以基于其接收到的信号对感知目标进行参数(如速度,距离,角度等)的估计,估计的结果可以用于后续的动作/行为识别等。目前存在的方案中,鉴于高频与低频的带宽相差较大,因此高频的感知流程与低频的感知流程是独立进行的,也即各自具备独立且完整的感知流程。In the 802.11bf standard, sensing devices can estimate parameters (such as speed, distance, and angle) of perceived targets based on received signals. The estimated results can be used for subsequent motion/behavior recognition. In existing solutions, due to the significant difference in bandwidth between high-frequency and low-frequency bands, the high-frequency and low-frequency sensing processes are performed independently, meaning each has its own independent and complete sensing process.
然而,上述方案的感知性能还有待提高。However, the perceptual performance of the above schemes needs to be improved.
本申请实施例提供一种通信方法、装置及系统,可以提高感知流程的灵活性,提高感知性能。The embodiments of the present application provide a communication method, device, and system that can improve the flexibility of the perception process and enhance perception performance.

为便于理解本申请的技术方案,下面将结合附图对本申请作进一步地描述。To facilitate understanding of the technical solution of the present application, the present application will be further described below with reference to the accompanying drawings.
本申请的说明书、权利要求书及附图中的术语“第一”和“第二”等仅用于区别不同对象,而不是用于描述特定顺序。此外,术语“包括”和“具有”以及它们的任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备等,没有限定于已列出的步骤或单元,而是可选地还包括没有列出的步骤或单元等,或可选地还包括对于这些过程、方法、产品或设备等固有的其它步骤或单元。The terms "first" and "second" in the specification, claims, and drawings of this application are used only to distinguish different objects and are not used to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to the process, method, product, or device.
在本文中提及的“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员可以显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it refer to independent or alternative embodiments that are mutually exclusive of other embodiments. It will be understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
在本申请中,“至少一个(项)”是指一个或者多个,“多个”是指两个或两个以上,“至少两个(项)”是指两个或三个及三个以上,“和/或”,用于描述关联对象的关联关系,表示可以存在三种关系,例如,“A和/或B”可以表示:只存在A,只存在B以及同时存在A和B三种情况,其中A,B可以是单数或者复数。“或”表示可以存在两种关系,如只存在A、只存在B;在A和B互不排斥时,也可以表示存在三种关系,如只存在A、只存在B、同时存在A和B。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达,是指这些项中的任意组合。例如,a,b或c中的至少一项(个),可以表示:a,b,c,“a和b”,“a和c”,“b和c”,或“a和b和c”。In this application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three and more than three, and "and/or" is used to describe the association relationship of associated objects, indicating that three relationships can exist. For example, "A and/or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. "Or" means that two relationships can exist, such as only A exists, only B exists; when A and B are not mutually exclusive, it can also mean that three relationships exist, such as only A exists, only B exists, and A and B exist at the same time. The character "/" generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c".
在本申请中,“指示”可以包括直接指示、间接指示、显示指示、隐式指示。当描述某一指示信息用于指示A时,可以理解为该指示信息携带A、直接指示A,或间接指示A。In this application, "indication" may include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.
本申请中,指示信息所指示的信息,称为待指示信息。在具体实现过程中,对待指示信息进行指示的方式有很多种,例如但不限于,可以直接指示待指示信息,如待指示信息本身或者该待指示信息的索引等。也可以通过指示其他信息来间接指示待指示信息,其中该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分,而待指示信息的其他部分则是已知的或者提前约定的。例如,还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示,从而在一定程度上降低指示开销。此外,待指示信息可以作为一个整体一起发送,也可以分成多个子信息分开发送,而且这些子信息的发送周期和/或发送时机可以相同,也可以不同。In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. In addition, the information to be indicated can be sent together as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and/or sending time of these sub-information can be the same or different.
本申请中,“传输”包括发送或接收。In this application, "transmit" includes sending or receiving.
在本申请中,“发送”和“接收”,表示信号传递的走向。例如,“向XX发送信息”可以理解为该信息的目的端是XX,可以包括通过空口直接发送,也包括其他单元或模块通过空口间接发送。“接收来自YY的信息”可以理解为该信息的源端是YY,可以包括通过空口直接从YY接收,也可以包括通过空口从其他单元或模块间接地从YY接收。“发送”也可以理解为芯片接口的“输出”,“接收”也可以理解为芯片接口的“输入”。换言之,发送和接收可以是在设备之间进行的,例如,网络设备和终端设备之间进行的,也可以是在设备内进行的,例如,通过总线、走线或接口在设备内的部件之间、模组之间、芯片之间、软件模块或者硬件模块之间发送或接收。In this application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information is XX, which can include direct sending through the air interface, and also include indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information is YY, which can include direct receiving from YY through the air interface, and also include indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be carried out between devices, for example, between network devices and terminal devices, or can be carried out within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, trace or interface.

以下介绍本申请涉及的方法。The following describes the method involved in this application.
低频的感知流程,与高频的感知具备类似的流程。通常来说,高频与低频的带宽相差较大,高频的感知流程与低频的感知流程是独立进行的,也即各自具备独立且完整的感知流程。对于高频来说,其带宽较大,如一个信道的带宽可以为2.16GHz(仅为示例),大带宽可以提供更好的感知性能,如更好的距离分辨率,更高的精度等。在高频的标准中,PPDU(或称为信号,或OFDM符号等)的发送带宽可以大于或等于320MHz。但高频由于衰减较大,一般采用方向性地发送信号或接收信号,方向性地发送信号或接收信号容易受到遮挡或波束不对齐的影响等,这一定程度上会影响高频之间进行感知的信令交互。当感知测量交互中的信令交互被影响时,会导致感知测量交互无法进行,无法完成测量。不同于高频,低频的带宽相对较小(如802.11be协议中PPDU的最大带宽可以为320MHz),感知性能相对受限。但是低频一般采用全向发送,受到遮挡的可能性较小,因此感知测量交互中的各种帧可以被有效地传输。此处关于感知的相关说明同样适用于测距,对于测距,此处不再赘述。The low-frequency perception process is similar to the high-frequency perception process. Generally speaking, the bandwidth of high and low frequencies differs significantly, and the high-frequency perception process is independent of the low-frequency perception process, meaning each has its own independent and complete perception process. High frequencies have a larger bandwidth, such as a channel bandwidth of 2.16 GHz (for example). This larger bandwidth provides better perception performance, such as improved range resolution and higher accuracy. In high-frequency standards, the transmission bandwidth of a PPDU (also known as a signal or OFDM symbol) can be greater than or equal to 320 MHz. However, due to the significant attenuation at high frequencies, signals are generally transmitted or received directionally. This directional transmission or reception is susceptible to obstruction and beam misalignment, which can affect the signaling interaction for perception between high frequencies. If this signaling interaction is affected, the perception measurement interaction cannot proceed and the measurement cannot be completed. Unlike high frequencies, low frequencies have relatively smaller bandwidths (for example, the maximum PPDU bandwidth in the 802.11be protocol is 320 MHz), resulting in relatively limited perception performance. However, low frequencies are generally transmitted omnidirectionally, making them less likely to be blocked. Therefore, the various frames involved in the perception measurement interaction can be transmitted efficiently. The descriptions of perception here also apply to ranging, so we will not elaborate on this here.
考虑到未来的设备可以同时具备高频和低频的通信或感知能力等,因此,本申请提供一种感知通信方法、测距通信方法、装置及系统。Considering that future devices may have both high-frequency and low-frequency communication or perception capabilities, the present application provides a perception communication method, a ranging communication method, an apparatus, and a system.
本申请中,低频可以辅助高频完成感知测量或测距,或者高频与低频协作完成感知测量或测距,高频与低频之间的协作可以更为紧密,从而可以有效地利用高低频的各自优势,更好地支持感知测量或测距交互的完成,提高感知性能或测距性能。如本申请可以提高感知流程或测距流程的稳健性,能够充分利用高频的大带宽优势来提高感知或测距的精度。另外,本申请还可以支持更多灵活的高低频感知或测距应用。In this application, low frequency can assist high frequency to complete perception measurement or ranging, or high frequency and low frequency can collaborate to complete perception measurement or ranging. The collaboration between high frequency and low frequency can be closer, so that the respective advantages of high and low frequencies can be effectively utilized to better support the completion of perception measurement or ranging interaction, and improve perception performance or ranging performance. For example, this application can improve the robustness of the perception process or ranging process, and can make full use of the large bandwidth advantage of high frequency to improve the accuracy of perception or ranging. In addition, this application can also support more flexible high and low frequency perception or ranging applications.

The receiver of the first PPDU can also be referred to as a perception receiver, as shown in Figures 5 to 9 below, and the receiver of the first PPDU (i.e., the perception receiver) can also be a perception responder. For example, in the case of the perceptual communication method, the transmitter of the second PPDU can also be referred to as the perceptual transmitter, as shown in Figures 5 to 9 below. The transmitter of the second PPDU (also known as the perceptual transmitter) can also be the perceptual responder. The receiver of the second PPDU can also be referred to as the perceptual receiver, as shown in Figures 5 to 9 below. The receiver of the second PPDU (also known as the perceptual receiver) can also be the perceptual initiator. The description of the transmitter and receiver is not repeated here.
本申请中,控制帧通过低频传输时,可以有如下方式:In this application, when the control frame is transmitted via low frequency, it can be transmitted in the following ways:
方式1、控制帧的接收地址为广播地址。控制帧的发送端可以全向地发送该控制帧。比如控制帧的接收端的数量为N个,N为正整数。如N大于或等于2时,控制帧的发送端可以同时向N个接收端发送M个控制帧,该控制帧可以包括:该控制帧的发送端为N个接收端中的每个接收端分配的信息(如包括测量资源等)。示例性的,M=1。Mode 1: The receiving address of the control frame is a broadcast address. The sender of the control frame can send the control frame omnidirectionally. For example, the number of control frame receivers is N, where N is a positive integer. If N is greater than or equal to 2, the sender of the control frame can simultaneously send M control frames to the N receivers. The control frames may include: information allocated by the sender of the control frame to each of the N receivers (such as measurement resources). For example, M = 1.
控制帧的发送端和接收端可以根据感知通信方法或测距通信方法的不同而不同,或者,根据测量交互流程的不同而不同,对于控制帧的发送端和接收端的具体产品形态,此处不再详述。The sender and receiver of the control frame may vary depending on the perception communication method or the ranging communication method, or may vary depending on the measurement interaction process. The specific product forms of the sender and receiver of the control frame will not be described in detail here.
方式2、控制帧的接收地址为接收端的地址。控制帧的发送端可以全向地发送N个控制帧,每个控制帧对应一个接收端。N为正整数。如N大于或等于2时,控制帧的发送端可以在不同时刻分别发送M个控制帧。该控制帧的地址可以为对应的接收端的地址。前述一个时刻可以对应一个控制帧。示例性的,M=N。前述不同时刻可以包括起始时刻的不同或持续时长的不同或结束时刻的不同。Method 2: The receiving address of the control frame is the address of the receiving end. The control frame transmitter can send N control frames omnidirectionally, with each control frame corresponding to a receiving end. N is a positive integer. If N is greater than or equal to 2, the control frame transmitter can send M control frames at different times. The address of the control frame can be the address of the corresponding receiving end. Each time can correspond to one control frame. For example, M = N. The different times can include different starting times, different durations, or different ending times.
本申请中,由于低频上传输的信号受到遮挡的影响小,因此通过在低频传输控制帧,可以减少该控制帧受环境等因素的影响,提高控制帧传输的可靠性。In the present application, since the signal transmitted at low frequency is less affected by obstruction, by transmitting the control frame at low frequency, the influence of environmental factors on the control frame can be reduced, thereby improving the reliability of control frame transmission.
本申请实施例中,第一PPDU和第二PPDU在低频传输时,可以有如下方式:In the embodiment of the present application, when the first PPDU and the second PPDU are transmitted at a low frequency, the following methods can be used:
方式3、针对第一PPDU而言,第一PPDU的发送端(包括感知发送端或测距发送端)可以全向发送第一PPDU。该第一PPDU的接收端可以由该第一PPDU的控制帧指示,也即该第一PPDU的控制帧可以指示哪些接收端需要接收该第一PPDU。Mode 3: For the first PPDU, the transmitter of the first PPDU (including the sensing transmitter or the ranging transmitter) may transmit the first PPDU omnidirectionally. The receiver of the first PPDU may be indicated by a control frame of the first PPDU, that is, the control frame of the first PPDU may indicate which receivers need to receive the first PPDU.
方式4、针对第二PPDU而言,第二PPDU的发送端(包括感知发送端或测距发送端)可以全向发送第二PPDU。该第二PPDU的发送端可以由该第二PPDU的控制帧来指示,比如接收到该第二PPDU的控制帧的装置可以发送第二PPDU。Mode 4: For the second PPDU, the transmitter of the second PPDU (including the sensing transmitter or the ranging transmitter) can transmit the second PPDU omnidirectionally. The transmitter of the second PPDU can be indicated by the control frame of the second PPDU. For example, a device that receives the control frame of the second PPDU can transmit the second PPDU.
本申请中,控制帧通过高频传输时,可以有如下方式:In this application, when the control frame is transmitted via high frequency, it can be in the following ways:
方式5、控制帧的接收地址为广播地址。控制帧的发送端可以发送M个控制帧,每个控制帧包括:感知发起端为N个感知响应端中的每个感知响应端分配的信息。示例性的,M=N。或者,M>N,或者,M<N。控制帧的发送端可以全向发送上述多个控制帧,或者,也可以定向发送上述多个控制帧。定向发送多个控制帧也可以理解为每个控制帧的发送方向不同。Mode 5: The receiving address of the control frame is a broadcast address. The control frame transmitter can send M control frames, each of which includes information assigned by the sensing initiator to each of the N sensing responders. For example, M = N. Alternatively, M > N, or M < N. The control frame transmitter can send these multiple control frames omnidirectionally or directionally. Directed transmission of multiple control frames can also be understood as each control frame being sent in a different direction.
方式6、控制帧的接收地址为接收端的地址。控制帧的发送端可以定向地发送M个控制帧。每个控制帧的发送方向可以不同。控制帧的发送端可以向不同方向发送控制帧,以保证N个接收端均可以接收到该控制帧。Mode 6: The receiving address of the control frame is the address of the receiving end. The control frame transmitter can send M control frames in a directionally distributed manner. Each control frame can be sent in a different direction. The control frame transmitter can send control frames in different directions to ensure that N receiving ends can receive the control frame.
作为一个示例,控制帧可以包括:该控制帧的发送端为N个接收端中的每个接收端分配的信息。作为另一个示例,控制帧可以包括该控制帧的发送端为一个接收端分配的信息。从而,不同方向上的控制帧可以对应于不同的接收端。As an example, a control frame may include information allocated by the control frame's transmitter to each of N receiving terminals. As another example, a control frame may include information allocated by the control frame's transmitter to a single receiving terminal. Thus, control frames in different directions may correspond to different receiving terminals.
上述关于控制帧的传输方式也可以适用于该控制帧的回复帧,对于回复帧的传输方式,此处不再详述。The above-mentioned transmission method of the control frame can also be applied to the reply frame of the control frame. The transmission method of the reply frame will not be described in detail here.
本申请中,第一PPDU或第二PPDU在高频传输时,可以有如下方式:In this application, when the first PPDU or the second PPDU is transmitted at a high frequency, the following methods may be used:
方式7、针对第一PPDU而言,发送端(包括感知发送端或测距发送端)可以在不同方向发送第一PPDU。Mode 7: For the first PPDU, the transmitter (including the sensing transmitter or the ranging transmitter) can send the first PPDU in different directions.
方式8、针对第二PPDU而言,N个发送端可以以SU的形式发送第二PPDU。SU的形式指的是:这N个发送端可以以时分的方式在不同的时刻(或不同的时间段)分别发送第二PPDU。或者,针对第二PPDU而言,N个发送端可以以MU的形式发送第二PPDU。MU的形式指的是:这N个发送端可以同时发送第二PPDU,比如正交频分多址(orthogonal frequency division multiple access,OFDMA)的传输方式和/或多用户-多输入多输出(multi-user multiple-input multiple-output,MU-MIMO)的传输方式。虽然N个发送端是同时发送第二PPDU的,但是这N个发送端可以在不同的传输资源上分别发送第二PPDU,从而可以减少干扰或尽可能地避免干扰。本申请中,N个发送端同时发送第二PPDU可以理解为N个发送端分别在同一个时间段内发送第二PPDU。对于这一段时间的具体持续时长,本申请不作限定。Mode 8: For the second PPDU, N transmitters may send the second PPDU in the form of SU. The SU form means that the N transmitters may send the second PPDU at different times (or different time periods) in a time-division manner. Alternatively, for the second PPDU, the N transmitters may send the second PPDU in the form of MU. The MU form means that the N transmitters may send the second PPDU simultaneously, such as using an orthogonal frequency division multiple access (OFDMA) transmission mode and/or a multi-user multiple-input multiple-output (MU-MIMO) transmission mode. Although the N transmitters send the second PPDU simultaneously, they may send the second PPDU separately on different transmission resources, thereby reducing or minimizing interference. In this application, N transmitters sending the second PPDU simultaneously may be understood as N transmitters sending the second PPDU separately within the same time period. This application does not limit the specific duration of this time period.
为便于后续引用,因此本申请通过不同的编号区分不同的方式或示例等,但是不应将其理解为对本申请实施例的限定。上述方式1~方式8所示的传输方式仅为示例,在具体实现中,控制帧或感知PPDU或测距PPDU还可以具有其他传输方式,本申请不作限定。For ease of subsequent reference, this application uses different numbers to distinguish different methods or examples, but this should not be understood as limiting the embodiments of this application. The transmission methods shown in the above methods 1 to 8 are only examples. In specific implementations, control frames, sensing PPDUs, or ranging PPDUs can also have other transmission methods, which are not limited in this application.
针对感知通信方法而言,前述控制帧可以包括但不限于感知轮询触发帧(或称为感知轮询帧)、感知NDPA帧、感知SR2SI探测触发帧、感知报告触发帧、发给自己的允许发送(clear to send,CTS)(CTS-to-self)帧或报告帧。感知NDPA帧对应的感知PPDU可以包括第一PPDU,感知SR2SI探测触发帧对应的感知PPDU可以包括第二PPDU。此处所示的控制帧、回复帧或感知PPDU是以图4所示的TB感知测量交互或图10所示的Non-TB感知测量交互或图14a~图20b所示的感知测量交互为例示出的。随着标准的进展,后续还可能会出现其他类型的用于感知的控制帧等,本申请对此不作限定。For the perception communication method, the aforementioned control frame may include, but is not limited to, a perception polling trigger frame (or perception polling frame), a perception NDPA frame, a perception SR2SI detection trigger frame, a perception report trigger frame, a clear to send (CTS) (CTS-to-self) frame or a report frame. The perception PPDU corresponding to the perception NDPA frame may include a first PPDU, and the perception PPDU corresponding to the perception SR2SI detection trigger frame may include a second PPDU. The control frame, reply frame or perception PPDU shown here is illustrated by taking the TB perception measurement interaction shown in Figure 4 or the Non-TB perception measurement interaction shown in Figure 10 or the perception measurement interaction shown in Figures 14a to 20b as an example. As the standard progresses, other types of control frames for perception may appear in the future, and this application does not limit this.

下文详细介绍本申请所示的感知通信方法。The following is a detailed description of the perceptual communication method shown in this application.
以下介绍本申请实施例涉及的感知通信方法中的一些装置。The following introduces some devices in the perception communication method involved in the embodiments of the present application.
感知发起端(sensing initiator):发起感知行为的装置;或者,发起感知测量会话的装置;或者,发送感知测量请求(sensing measurement request)帧的装置。如该感知发起端可以在低频发送感知测量请求帧,或者,在高频发送感知测量请求帧。感知发起端可以是感知发送端或感知接收端。Sensing initiator: A device that initiates a sensing action; or a device that initiates a sensing measurement session; or a device that sends a sensing measurement request frame. For example, the sensing initiator can send sensing measurement request frames at a low frequency or at a high frequency. A sensing initiator can be a sensing transmitter or a sensing receiver.
感知响应端(sensing responder):响应感知发起端发起的感知行为,参与到感知的装置。如感知响应端可以接收感知测量请求帧,并回复感知测量响应(sensing measurementresponse)帧。如该感知响应端可以在低频回复感知测量响应帧,或者,在高频回复感知测量响应帧。作为一个示例,针对基于触发的(triggerbased,TB)感知测量交互来说,感知发起端可以为AP,感知响应端可以为STA。作为另一个示例,针对基于非触发的(non-TB)感知测量交互来说,感知发起端可以为STA,感知响应端可以为AP。感知响应端可以是感知发送端或感知接收端。Sensing responder: A device that responds to the sensing behavior initiated by the sensing initiator and participates in the sensing. For example, the sensing responder can receive a sensing measurement request frame and reply with a sensing measurement response frame. For example, the sensing responder can reply with a sensing measurement response frame at a low frequency, or reply with a sensing measurement response frame at a high frequency. As an example, for a trigger-based (TB) sensing measurement interaction, the sensing initiator can be an AP and the sensing responder can be an STA. As another example, for a non-trigger-based (non-TB) sensing measurement interaction, the sensing initiator can be an STA and the sensing responder can be an AP. The sensing responder can be a sensing transmitter or a sensing receiver.
感知发送端(sensingtransmitter):发送感知PPDU的装置。如感知发送端可以在低频发送感知PPDU,或者在高频发送感知PPDU。Sensing transmitter: A device that sends sensing PPDUs. For example, a sensing transmitter can send sensing PPDUs at a low frequency or at a high frequency.
感知接收端(sensing receiver):接收感知PPDU的装置。如感知接收端可以在低频接收感知PPDU,或者在高频接收感知PPDU。Sensing Receiver: A device that receives sensing PPDUs. For example, a sensing receiver can receive sensing PPDUs at a low frequency or at a high frequency.
图3是本申请实施例提供的感知流程的阶段示意图。如图3所示,感知流程的阶段可以包括:感知能力交互(sensing capabilities exchange)阶段、感知测量会话(sensing measurement session)建立阶段、感知测量交互(sensing measurement exchange)阶段和感知测量会话终止(sensingmeasurementsessiontermination)阶段。FIG3 is a schematic diagram of the stages of a sensing process provided by an embodiment of the present application. As shown in FIG3 , the stages of the sensing process may include: a sensing capabilities exchange stage, a sensing measurement session establishment stage, a sensing measurement exchange stage, and a sensing measurement session termination stage.
不同设备之间可以进行设备之间的能力交互(capabilities exchange),如图3所示的感知能力交互阶段。通过基本能力的交互,设备之间可以相互了解彼此的感知能力。示例性的,感知发起端可以向感知响应端发送感知能力元素,该感知能力元素中可以携带感知发起端的感知能力。感知响应端可以向感知发起端发送感知能力元素,该感知能力元素可以携带感知响应端的感知能力。通常来说,在感知能力交互阶段,能力交互的设备之间还未区分感知发起端或感知响应端。如可以在完成能力交互之后区分感知发起端或感知响应端,即发送感知测量请求帧的装置可以是感知发起端。Capabilities exchange can be performed between different devices, as shown in the perception capability interaction stage in Figure 3. Through the interaction of basic capabilities, devices can understand each other's perception capabilities. Exemplarily, the perception initiator can send a perception capability element to the perception responder, and the perception capability element can carry the perception capability of the perception initiator. The perception responder can send a perception capability element to the perception initiator, and the perception capability element can carry the perception capability of the perception responder. Generally speaking, in the perception capability interaction stage, the perception initiator or the perception responder is not distinguished between the devices that interact with the capabilities. For example, the perception initiator or the perception responder can be distinguished after the capability interaction is completed, that is, the device that sends the perception measurement request frame can be the perception initiator.
感知装置完成能力交互之后,在需要发起感知测量会话时,感知发起端可以通过发送感知测量请求(sensing measurement request)帧发起感知测量会话的建立,感知响应端接收该感知测量请求并回复感知测量响应(sensing measurement response)帧。感知发起端可以通过该感知测量会话建立阶段,针对不同的感知任务给不同的感知响应端分配不同的角色、参数,完成感知测量会话的建立。该感知测量会话建立阶段中主要协商感知中的相关参数,如设备的接收/发射角色、感知带宽、是否需要反馈信道状态信息(channel state information,CSI)矩阵、是否需要反馈感知测量报告帧等。After the sensing device completes capability interaction, when a sensing measurement session needs to be initiated, the sensing initiator can initiate the establishment of the sensing measurement session by sending a sensing measurement request frame. The sensing responder receives the sensing measurement request and responds with a sensing measurement response frame. During this sensing measurement session establishment phase, the sensing initiator can assign different roles and parameters to different sensing responders for different sensing tasks to complete the establishment of the sensing measurement session. During this sensing measurement session establishment phase, the relevant parameters in the sensing process are negotiated, such as the device's receive/transmit role, sensing bandwidth, whether the channel state information (CSI) matrix needs to be fed back, and whether the sensing measurement report frame needs to be fed back.
完成感知测量会话的建立之后,感知发起端可以发起一个或者多个感知测量交互。也即,感知测量会话中可以包括一个或多个感知测量交互。感知测量交互可以分为基于触发的(trigger based,TB)感知测量交互(TB sensing measurement instance)和非基于触发的(non-trigger based,non-TB)感知测量交互(non-TB sensing measurement instance)。TB感知测量交互一般由AP发起(如该AP作为感知发起端),non-TB感知测量交互一般由STA发起(如该STA作为感知发起端)。After establishing a sensing measurement session, the sensing initiator can initiate one or more sensing measurement interactions. That is, a sensing measurement session can include one or more sensing measurement interactions. Sensing measurement interactions can be divided into trigger-based (TB) sensing measurement interactions (TB sensing measurement instances) and non-trigger-based (non-TB) sensing measurement interactions (non-TB sensing measurement instances). TB sensing measurement interactions are generally initiated by the AP (e.g., the AP acts as the sensing initiator), while non-TB sensing measurement interactions are generally initiated by the STA (e.g., the STA acts as the sensing initiator).
在一段时间之后,如果感知发起端或感知响应端不需要该感知测量会话时,则感知发起端或感知响应端可以通过发送感知测量会话终止帧关闭(或终止)感知测量会话,如图3所示的感知测量会话终止阶段。After a period of time, if the perception initiator or the perception responder no longer needs the perception measurement session, the perception initiator or the perception responder can close (or terminate) the perception measurement session by sending a perception measurement session termination frame, as shown in the perception measurement session termination phase in Figure 3.
图3所示的感知流程可以对应于不同的感知任务。如感知发起端可以针对跌倒检测任务发起感知流程,在感知测量交互阶段,感知发起端(或感知响应端)可以通过发送若干个感知PPDU来检测目标的信息。又如感知发起端可以针对呼吸检测任务发起感知流程,在感知测量交互阶段,感知发起端(或感知响应端)同样可以通过发送若干个感知PPDU来检测目标的信息。此处所列举的目标的信息可以包括目标的运动信息等。如通过感知流程检测到的目标可以是运动状态,也可以是静止状态,本申请实施例对此不作限定。The perception process shown in Figure 3 can correspond to different perception tasks. For example, the perception initiator can initiate a perception process for a fall detection task. During the perception measurement interaction phase, the perception initiator (or perception response end) can detect the target information by sending several perception PPDUs. For another example, the perception initiator can initiate a perception process for a breathing detection task. During the perception measurement interaction phase, the perception initiator (or perception response end) can also detect the target information by sending several perception PPDUs. The target information listed here may include the target's motion information, etc. For example, the target detected by the perception process can be in motion or in a stationary state, which is not limited in the embodiments of the present application.
图3所示的感知流程也可以适用于测距流程,比如测距发起端与测距响应端可以在测距能力交互阶段交互各自的能力,然后在测距测量会话阶段为不同的感知响应端分配角色、参数,完成测距测量会话的建立。完成测距测量会话之后,测距发起端可以发起一个或多个测距测量交互。关于测距流程的说明可以参考感知流程,本申请不作赘述。The perception process shown in Figure 3 can also be applied to the ranging process. For example, the ranging initiator and the ranging responder can exchange their respective capabilities in the ranging capability interaction phase, and then assign roles and parameters to different perception responders in the ranging measurement session phase to complete the establishment of the ranging measurement session. After completing the ranging measurement session, the ranging initiator can initiate one or more ranging measurement interactions. For an explanation of the ranging process, please refer to the perception process, and this application will not elaborate on it.
以下详细说明感知测量会话中的感知测量交互流程。The following details the perception measurement interaction process in the perception measurement session.
图4是本申请实施例提供的TB感知测量交互的流程示意图。如图4所示,一个TB感知测量交互可以包括如下四个阶段中的至少一个阶段:轮询(polling)阶段、NDPA探测(sounding)阶段、触发帧(trigger frame,TF)探测(TF sounding)阶段或报告(reporting)阶段。例如,一个TB感知测量交互可以包括一个阶段时,该阶段可以是TF探测阶段。又例如,一个TB感知测量交互可以包括NDPA探测阶段和TF探测阶段。又例如,一个TB感知测量交互可以包括轮询阶段和TF探测阶段。又例如,一个TB感知测量交互可以包括轮询阶段、NDPA探测阶段和报告阶段。又例如,一个TB感知测量交互可以包括TF探测阶段和报告阶段。又例如,一个TB感知测量交互可以包括NDPA探测阶段和报告阶段。又例如,一个TB测量阶段可以包括轮询阶段、NDPA探测阶段、TF探测阶段和报告阶段(如图4所示)等,此处不再一一列举。此处关于阶段的说明下文提供的各个方法均适用,下文不再赘述。下文虽然同时示出了轮询阶段、NDPA探测阶段、TF探测阶段和报告阶段,但是不应将其理解为对本申请的限定。以下详细说明各个阶段:Figure 4 is a schematic diagram of the process of TB perception measurement interaction provided in an embodiment of the present application. As shown in Figure 4, a TB perception measurement interaction may include at least one of the following four phases: a polling phase, an NDPA sounding phase, a trigger frame (TF) sounding phase, or a reporting phase. For example, when a TB perception measurement interaction may include one phase, the phase may be a TF sounding phase. For another example, a TB perception measurement interaction may include an NDPA sounding phase and a TF sounding phase. For another example, a TB perception measurement interaction may include a polling phase and a TF sounding phase. For another example, a TB perception measurement interaction may include a polling phase, an NDPA sounding phase, and a reporting phase. For another example, a TB perception measurement interaction may include an NDPA sounding phase and a reporting phase. For another example, a TB perception measurement interaction may include an NDPA sounding phase and a reporting phase. For another example, a TB measurement phase may include a polling phase, an NDPA sounding phase, a TF sounding phase, and a reporting phase (as shown in Figure 4), etc., which are not listed here one by one. The description of the phases here is applicable to all methods provided below and will not be repeated below. Although the polling phase, NDPA detection phase, TF detection phase, and reporting phase are shown below, they should not be understood as limiting the present application. The following details each phase:
(1)轮询阶段(1) Polling phase
在TB感知测量交互中,AP作为感知发起端,在轮询阶段可以向想要邀请参与到本次感知测量交互的STA发送感知轮询触发帧,邀请各个STA参与本次感知测量交互。参与本次感知测量交互的STA可以在AP分配的资源上回复CTS-to-self帧,从而确认参与本次感知测量交互。也即,感知轮询触发帧可以用于感知发起端向一个或多个感知响应端询问该一个或多个感知响应端是否参加本次感知测量交互。CTS-to-self帧可以用于确认参加本次感知测量交互。如图4所示,AP可以邀请STA1~STA6参与到本次感知测量交互过程中。STA1、STA2、STA4和STA5确认参与本次感知测量交互。In TB perception measurement interaction, the AP, as the perception initiator, can send a perception polling trigger frame to the STAs it wants to invite to participate in this perception measurement interaction during the polling phase, inviting each STA to participate in this perception measurement interaction. The STAs participating in this perception measurement interaction can reply with a CTS-to-self frame on the resources allocated by the AP to confirm their participation in this perception measurement interaction. In other words, the perception polling trigger frame can be used by the perception initiator to inquire with one or more perception responders whether they participate in this perception measurement interaction. The CTS-to-self frame can be used to confirm participation in this perception measurement interaction. As shown in Figure 4, the AP can invite STA1 to STA6 to participate in this perception measurement interaction process. STA1, STA2, STA4, and STA5 confirm their participation in this perception measurement interaction.
在感知响应端的个数较多,感知发起端无法一次实现与所有感知响应端的轮询时,感知发起端可以发起多次轮询。如当感知响应端的数量大于感知发起端可以分配的资源单元(resourceunit,RU)数(仅为示例)的情况下,感知发起端可以发起多次轮询。When there are a large number of sensing responders and the sensing initiator cannot poll all of them at once, the sensing initiator can initiate multiple pollings. For example, when the number of sensing responders is greater than the number of resource units (RUs) that the sensing initiator can allocate (for example only), the sensing initiator can initiate multiple pollings.
本申请实施例中,感知轮询触发帧的名称仅为示例,如该感知轮询触发帧也可以称为感知轮询帧或轮询触发帧或轮询帧(或简称为轮询)等,本申请不作限定。为便于简洁,下文以轮询帧为例进行说明。In the embodiment of the present application, the name of the perception polling trigger frame is only an example. For example, the perception polling trigger frame can also be called a perception polling frame, a polling trigger frame, or a polling frame (or simply a polling frame), etc., and this application does not limit it. For the sake of simplicity, the following description takes the polling frame as an example.
(2)NDPA探测阶段(2) NDPA detection phase
在NDPA探测阶段,感知发起端发送感知NDPA帧给一个或多个确认参与NDPA探测的感知响应端,以及在预定的间隔时长后(例如短帧间距(short inter frame space,SIFS))之后发送SI2SR NDP。感知响应端根据感知NDPA帧中的信息接收该SI2SR NDP,实现感知测量。也即,感知NDPA帧可以用于调度一个或多个参与NDPA探测阶段的感知响应端。SI2SR NDP为感知PPDU中的一种,该SI2SR NDP可以用于感知,以实现感知发起端到感知响应端的感知测量。该SI2SR NDP可以是如下任一种类型:感知NDP、测距NDP、IMMW感知NDP、IMMW测距NDP或数据PPDU。对于SI2SR NDP的具体格式,本申请不作限定。During the NDPA detection phase, the perception initiator sends a perception NDPA frame to one or more perception responders that confirm their participation in the NDPA detection, and sends a SI2SR NDP after a predetermined interval (e.g., short inter frame space (SIFS)). The perception responder receives the SI2SR NDP based on the information in the perception NDPA frame to implement perception measurement. That is, the perception NDPA frame can be used to schedule one or more perception responders participating in the NDPA detection phase. SI2SR NDP is a type of perception PPDU, and the SI2SR NDP can be used for perception to implement perception measurement from the perception initiator to the perception responder. The SI2SR NDP can be any of the following types: perception NDP, ranging NDP, IMMW perception NDP, IMMW ranging NDP, or data PPDU. This application does not limit the specific format of SI2SR NDP.
对于预定的间隔时长的具体时长,本申请实施例不作限定,SIFS仅为举例。本申请实施例中,感知NDAP帧的名称仅为示例,如该感知NDPA帧也可以称为NDPA帧(或简称为NDPA)等,本申请不作限定。为便于简洁,下文均以NDPA帧为例进行说明。The specific duration of the predetermined interval is not limited in this embodiment of the present application, and SIFS is only an example. In this embodiment of the present application, the name of the perceived NDAP frame is only an example. For example, the perceived NDPA frame can also be called an NDPA frame (or simply NDPA), etc., which is not limited in this application. For the sake of simplicity, the following description uses the NDPA frame as an example.
(3)TF探测阶段(3) TF detection stage
在TF探测阶段,感知发起端发送感知SR2SI探测触发帧给一个或多个确认参与TF探测的感知响应端,感知响应端根据SR2SI探测触发帧分配的信息发送SR2SI NDP,实现感知测量。也即,感知SR2SI探测触发帧可以用于为感知响应端分配测量资源。感知响应端在接收到该感知SR2SI探测触发帧之后,可以按照分配好的测量资源发送SR2SI NDP。该测量资源可以包括但不限于空间流或空时流等。During the TF detection phase, the sensing initiator sends a sensing SR2SI detection trigger frame to one or more sensing responders that have confirmed their participation in TF detection. Based on the information allocated in the SR2SI detection trigger frame, the sensing responders send SR2SI NDPs to implement sensing measurements. In other words, the sensing SR2SI detection trigger frame can be used to allocate measurement resources to the sensing responders. After receiving the sensing SR2SI detection trigger frame, the sensing responders can send SR2SI NDPs based on the allocated measurement resources. These measurement resources can include, but are not limited to, spatial streams or space-time streams.
在感知响应端的数量较多,如感知响应端的数量大于数量阈值,感知发起端可以发起多个TF探测阶段。示例性的,个数阈值可以由感知发起端可以调度的最大空间流数确定。也就是说,在感知响应端的数量大于数量阈值的情况下,感知发起端可能无法通过一个TF探测阶段完成感知测量,由此感知发起端可以发起多个TF探测阶段。If the number of sensing responders is large, for example, if the number of sensing responders is greater than a threshold, the sensing initiator may initiate multiple TF detection phases. For example, the threshold may be determined by the maximum number of spatial streams that the sensing initiator can schedule. In other words, if the number of sensing responders is greater than the threshold, the sensing initiator may not be able to complete the sensing measurement in one TF detection phase. Therefore, the sensing initiator may initiate multiple TF detection phases.
本申请实施例中,感知SR2SI探测触发帧的名称仅为示例,如该感知SR2SI探测触发帧也可以称为探测触发帧(或简称为探测触发)或感知探测触发帧等,本申请实施例不作限定。为便于简洁,下文均以探测触发帧为例进行说明。In the embodiment of the present application, the name of the perception SR2SI detection trigger frame is only an example. For example, the perception SR2SI detection trigger frame can also be called a detection trigger frame (or simply a detection trigger) or a perception detection trigger frame, etc., which is not limited in the embodiment of the present application. For the sake of simplicity, the following description uses the detection trigger frame as an example.
(4)报告阶段(4) Reporting stage
在报告阶段,感知发起端发送感知报告触发帧给一个或多个确认参与报告阶段的感知响应端,感知响应端根据感知报告触发帧发送感知测量报告帧。也即,感知报告触发帧可以用于为感知响应端分配资源,感知响应端可以按照分配的资源发送感知测量报告帧,该感知测量报告帧可以用于报告感知测量结果。During the reporting phase, the sensing initiator sends a sensing report trigger frame to one or more sensing responders that have confirmed their participation in the reporting phase. The sensing responders then send sensing measurement report frames based on the sensing report trigger frame. In other words, the sensing report trigger frame can be used to allocate resources to the sensing responders, which can then use the allocated resources to send sensing measurement report frames. These sensing measurement report frames can be used to report sensing measurement results.
本申请实施例中,感知报告触发帧的名称仅为示例,如该感知报告触发帧也可以称为报告触发帧(或简称为报告触发)等,本申请不作限定。感知测量报告帧也可以称为报告帧(或简称为报告)等,本申请不作限定。为便于简洁,下文均以报告触发帧和报告帧为例进行说明。In the embodiments of the present application, the name of the perception report trigger frame is only an example. For example, the perception report trigger frame may also be referred to as a report trigger frame (or simply a report trigger), etc., which is not limited in this application. The perception measurement report frame may also be referred to as a report frame (or simply a report), etc., which is not limited in this application. For the sake of simplicity, the following description uses the report trigger frame and the report frame as examples.
本申请实施例中,一个TB测量交互的不同阶段可以发生在一个感知可用窗口(sensing availability window)内。如一个TB测量交互同时包括上述四个阶段时,上述轮询阶段、NDPA探测阶段、TF探测阶段和报告阶段可以发生在一个感知可用窗口内。示例性的,一个感知可用窗口可以包括多个传输时机(transmission opportunity,TXOP),一个TXOP内可以包括一个或多个感知测量交互。In embodiments of the present application, the different phases of a TB measurement interaction may occur within a sensing availability window. For example, when a TB measurement interaction includes the aforementioned four phases, the polling phase, NDPA detection phase, TF detection phase, and reporting phase may occur within a sensing availability window. For example, a sensing availability window may include multiple transmission opportunities (TXOPs), and a TXOP may include one or more sensing measurement interactions.
图4中的STA1至STA2的角色可以为感知发送端,STA4至STA6的角色可以为感知接收端。AP发送感知轮询触发帧给STA1至STA5时,STA3未回复CTS-to-self帧,因此STA3不参与感知流程。感知轮询触发帧是可选的,STA6可以跳过轮询阶段。AP与STA4之间协商可以不反馈感知测量结果,因此图4中虽然STA4基于其接收到的SI2SR NDP完成了感知测量,但是在报告阶段,STA4可以不通过感知测量报告帧来报告感知测量结果,如通过上层报告感知测量结果。如感知测量结果可以包括CSI或信道冲击响应(channel impulse response,CIR)等。In Figure 4, STA1 through STA2 can act as sensing transmitters, while STA4 through STA6 can act as sensing receivers. When the AP sends a sensing poll trigger frame to STA1 through STA5, STA3 does not respond with a CTS-to-self frame, so STA3 does not participate in the sensing process. The sensing poll trigger frame is optional, and STA6 can skip the polling phase. The AP and STA4 negotiate not to feedback sensing measurement results. Therefore, although STA4 completes sensing measurements based on the received SI2SR NDP in Figure 4, during the reporting phase, STA4 can report the sensing measurement results not via a sensing measurement report frame, but rather via higher layers. For example, sensing measurement results can include CSI or channel impulse response (CIR).
如随着标准的进展,TB感知测量交互的具体流程可能会发生变化,因此图4所示的TB感知测量交互的流程仅为示例,不应将其理解为对本申请实施例的限定。当TB感知测量交互的流程发生变化时,下文所示的各个示例也可以随着变化。As standards evolve, the specific process of TB perception measurement interaction may change. Therefore, the process of TB perception measurement interaction shown in Figure 4 is only an example and should not be construed as limiting the embodiments of this application. If the process of TB perception measurement interaction changes, the various examples shown below may also change accordingly.
结合图4所示的TB感知测量交互和上文传输方式可以扩展出多种高低频协作的TB感知测量交互。下文通过不同的示例说明本申请实施例所示的感知通信方法。下文所示的示例一~示例五仅为示例,结合上文传输方式以及图4还可以扩展出更多的示例,本申请不再一一列举。此处关于感知通信方法的说明同样适用于下文所示的测距通信方法,下文不再赘述。In combination with the TB perception measurement interaction shown in Figure 4 and the above transmission method, a variety of high- and low-frequency collaborative TB perception measurement interactions can be expanded. The following describes the perception communication method shown in the embodiment of the present application through different examples. Examples 1 to 5 shown below are only examples. In combination with the above transmission method and Figure 4, more examples can be expanded, and this application will not list them one by one. The description of the perception communication method here also applies to the ranging communication method shown below, and will not be repeated below.
在第二频段为IMMW标准中涉及的频段时,下文示例一~示例五也可以称为IMMW高低频协作的TB感知测量交互,或IMMW TB感知测量交互,或IMMW高低频混合的TB感知测量交互。When the second frequency band is the frequency band involved in the IMMW standard, Examples 1 to 5 below can also be referred to as IMMW high- and low-frequency collaborative TB perception measurement interaction, or IMMW TB perception measurement interaction, or IMMW high- and low-frequency mixed TB perception measurement interaction.
为便于描述,下文在涉及具体例子时,将以两个感知响应端为例说明本申请所示的感知通信方法,但是,不应将感知响应端的数量作为对本申请的限定。For ease of description, when referring to specific examples below, two perception response terminals will be used as an example to illustrate the perception communication method shown in this application. However, the number of perception response terminals should not be used as a limitation to this application.
示例一、Example 1:
图5是本申请实施例提供的TB感知测量交互的一种流程示意图。图5中所示的各个阶段的其他说明可以参考图4,下文不再赘述。如图5所示,该TB感知测量交互可以包括:FIG5 is a flow chart of a TB perception measurement interaction provided by an embodiment of the present application. For other descriptions of the various stages shown in FIG5 , please refer to FIG4 and will not be repeated hereafter. As shown in FIG5 , the TB perception measurement interaction may include:
(1A)轮询阶段:感知发起端在第一频段发送轮询帧,对应的,感知响应端在第一频段接收该轮询帧。参与交互的感知响应端在第一频段回复CTS-to-self帧确认自己参加本次感知测量交互。(1A) Polling phase: The sensing initiator sends a polling frame in the first frequency band, and the sensing responder receives the polling frame in the first frequency band. The participating sensing responder replies with a CTS-to-self frame in the first frequency band to confirm its participation in this sensing measurement interaction.
感知发起端可以在第一频段(或称为低频)上全向发送轮询帧。该轮询帧的地址可以为广播地址。由于低频上的信号受到遮挡的影响较小,因此感知发起端通过在低频上发送轮询帧,可使得不同方向上的感知响应端均可以接收到该轮询帧。从而,可以高效地完成轮询,提高轮询效率。关于感知发起端在低频上发送轮询帧的说明还可以参考上述方式1,此处不再详述。The perception initiator can send polling frames omnidirectionally on the first frequency band (or called low frequency). The address of the polling frame can be a broadcast address. Since the signal on the low frequency is less affected by the obstruction, the perception initiator can send the polling frame on the low frequency so that the perception responding ends in different directions can receive the polling frame. In this way, polling can be completed efficiently and the polling efficiency is improved. For the description of the perception initiator sending the polling frame on the low frequency, please refer to the above method 1 and will not be described in detail here.
在感知响应端的数量大于或等于2个的情况下,作为一种可能的实现方式,感知发起端通过轮询帧可以调度各个感知响应端的资源互不干扰或者干扰小于阈值,如为不同的感知响应端分配不同的RU或多用户资源单元(multiple RU,MRU)或分布式资源单元(distributed resource unit,DRU)。从而各个感知响应端可以在同一时刻发送CTS-to-self帧。也即各个感知响应端可以采用多用户(multi-user,MU)的形式发送CTS-2-self帧。对于同一时刻的具体时长,本申请实施例不作限定。When the number of sensing responders is greater than or equal to two, as a possible implementation method, the sensing initiator can schedule the resources of each sensing responder through polling frames so that they do not interfere with each other or the interference is less than a threshold, such as allocating different RUs or multi-user resource units (MRUs) or distributed resource units (DRUs) to different sensing responders. In this way, each sensing responder can send a CTS-to-self frame at the same time. In other words, each sensing responder can send a CTS-2-self frame in the form of a multi-user (MU). The specific duration of the same moment is not limited in this embodiment of the application.
本申请实施例中,由于低频上发送的信号受到遮挡的影响较小,因此轮询阶段的交互通过在低频上完成,可以高效地完成轮询,提高轮询的效率。同时,感知响应端可以通过MU的方式高效地与感知发起端进行确认,进一步地提高了轮询效率。In the embodiment of the present application, since signals sent at low frequencies are less affected by obstructions, the interaction during the polling phase is completed at low frequencies, which allows for efficient polling and improves polling efficiency. Furthermore, the sensing responder can efficiently confirm with the sensing initiator through the MU, further improving polling efficiency.
(2A)NDPA探测阶段:感知发起端在第一频段发送NDPA帧,对应的,感知响应端在第一频段接收NDPA帧。感知发起端在第二频段发送用于感知的第一PPDU,对应的,感知响应端在第二频段接收该第一PPDU。(2A) NDPA detection phase: The sensing initiator sends an NDPA frame in the first frequency band, and the sensing responder receives the NDPA frame in the first frequency band. The sensing initiator sends a first PPDU for sensing in the second frequency band, and the sensing responder receives the first PPDU in the second frequency band.
感知发起端可以在低频上全向发送NDPA帧,该NDAP帧的接收地址可以为广播地址。感知发起端通过在低频上全向发送NDPA帧,可以使得该NDPA帧高效地发送且受到遮挡的影响较小。关于感知发起端在低频发送NDPA帧的说明可以参考上述方式1,此处不再详述。The perception initiator can send NDPA frames omnidirectionally at a low frequency, and the receiving address of the NDPA frame can be a broadcast address. By sending NDPA frames omnidirectionally at a low frequency, the perception initiator can send the NDPA frames efficiently and less affected by obstructions. For instructions on how the perception initiator sends NDPA frames at a low frequency, please refer to the above method 1 and will not be described in detail here.
本申请实施例中,在该NDPA探测阶段所在的感知测量交互中包括(1A)所示的轮询阶段的情况下,轮询帧、CTS-to-self帧以及NDPA帧均可以位于低频的同一个TXOP之内,由此可以减少信道竞争的次数。通常来说,AP或STA可以分配有服务周期(serviceperiod,SP),或者为多个STA之间分配SP。在SP内,其他设备可以不与被分配了SP的设备竞争信道。因此前述轮询帧、CTS-to-self帧和NDPA帧也可以位于AP分配的SP内,或者STA分配的SP内,或者位于AP与STA之间的SP内,本申请实施例对此不作限定。通常来说,可以由AP执行分配SP的步骤,当然随着标准的进展,后续还可能出现其他设备,本申请实施例对此不作限定。下文均以分配的SP为例,至于这个SP是哪个设备,或者是由哪个设备分配的,下文不再详述。In an embodiment of the present application, when the perception measurement interaction in which the NDPA detection phase is located includes the polling phase shown in (1A), the polling frame, CTS-to-self frame and NDPA frame can all be located within the same TXOP at a low frequency, thereby reducing the number of channel contentions. Generally speaking, the AP or STA can be assigned a service period (SP), or an SP can be assigned between multiple STAs. Within the SP, other devices may not compete for channels with the device to which the SP is assigned. Therefore, the aforementioned polling frame, CTS-to-self frame and NDPA frame can also be located within the SP assigned by the AP, or within the SP assigned by the STA, or within the SP between the AP and the STA, and this embodiment of the present application does not limit this. Generally speaking, the step of assigning SP can be performed by the AP. Of course, as the standard progresses, other devices may appear later, and this embodiment of the present application does not limit this. The following takes the assigned SP as an example. As for which device this SP is, or which device assigns it, it will not be described in detail below.
感知发起端在低频上发送NDPA帧之后,可以切换到高频上发送第一PPDU。关于第一PPDU在高频的发送方式可以参考7,此处不再详述。After the sensing initiator sends the NDPA frame at the low frequency, it can switch to the high frequency to send the first PPDU. For the sending method of the first PPDU at the high frequency, please refer to 7 and will not be described in detail here.
图5中,省略号中省略的是NDP。如当图5示出的是3个NDP的情况下,感知发起端可以在不同或相同的方向上发送这3个NDP,感知响应端1和感知响应端2可以接收这3个NDP。可选地,感知发起端可以再次在不同或相同的方向上发送这3个NDP,感知响应端2接收这3个NDP。对于NDP的具体发送方式,本申请实施例不作限定。In Figure 5 , the NDP is omitted in the ellipsis. For example, when Figure 5 shows three NDPs, the perception initiator can send these three NDPs in different or the same directions, and perception responder 1 and perception responder 2 can receive these three NDPs. Optionally, the perception initiator can again send these three NDPs in different or the same directions, and perception responder 2 can receive these three NDPs. The specific method of sending NDPs is not limited in this embodiment of the application.
本申请实施例中,在感知发起端从低频切换到高频之后,感知发起端可以进行信道竞争获得TXOP,在该TXOP内发送第一PPDU,或者,感知发起端可以在分配的SP内发送第一PPDU。示例性的,感知发起端发送的一个或多个第一PPDU可以属于同一个TXOP或一个SP。In an embodiment of the present application, after the sensing initiator switches from a low frequency to a high frequency, the sensing initiator may perform channel contention to obtain a TXOP and send a first PPDU within the TXOP, or the sensing initiator may send the first PPDU within an allocated SP. Exemplarily, one or more first PPDUs sent by the sensing initiator may belong to the same TXOP or SP.
本申请实施例中,NDPA帧通过在低频上发送,该NDPA帧可以高效地被发送且受到遮挡的影响较小,保证各个感知响应端可以接收到该NDPA帧。同时,第一PPDU通过在高频上发送,可以提高感知性能。In this embodiment of the present application, the NDPA frame is sent at a low frequency, which allows efficient transmission and minimizes the impact of obstructions, ensuring that each sensing response terminal can receive the NDPA frame. Furthermore, the first PPDU is sent at a high frequency, which improves sensing performance.
(3A)TF探测阶段:感知发起端在第一频段发送探测触发帧,对应的,感知响应端在第一频段接收该探测触发帧。感知响应端在第二频段发送用于感知的第二PPDU,对应的,感知发起端在第二频段接收该第二PPDU。(3A) TF detection phase: The sensing initiator sends a detection trigger frame in the first frequency band, and the sensing responder receives the detection trigger frame in the first frequency band. The sensing responder sends a second PPDU for sensing in the second frequency band, and the sensing initiator receives the second PPDU in the second frequency band.
在TF探测阶段所在的感知测量交互中包括(2A)所示的NDPA探测阶段的情况下,感知发起端在高频上发送完上述第一PPDU之后,可以切换到低频。In the case where the perception measurement interaction in which the TF detection phase is located includes the NDPA detection phase shown in (2A), the perception initiator can switch to the low frequency after sending the above-mentioned first PPDU at the high frequency.
在TF探测阶段所在的感知测量交互中包括(1A)所示的轮询阶段,不包括(2A)所示的NDPA探测阶段的情况下,感知发起端可以在低频上接收到CTS-to-self帧之后,可以继续在低频上发送探测触发帧。同理,此处关于感知发起端的说明同样适用于感知响应端。In the case where the perception measurement interaction in the TF detection phase includes the polling phase shown in (1A) but does not include the NDPA detection phase shown in (2A), the perception initiator can continue to send detection trigger frames on the low frequency after receiving the CTS-to-self frame on the low frequency. Similarly, the description of the perception initiator here also applies to the perception responder.
可选地,轮询帧、CTS-to-self帧、探测触发帧可以属于同一个TXOP或SP。Optionally, the polling frame, the CTS-to-self frame, and the detection trigger frame may belong to the same TXOP or SP.
作为一个示例,感知响应端的数量可以为1个。As an example, the number of perception response terminals may be 1.
作为另一个示例,感知响应端的数量可以大于或等于2个。在感知响应端的数量大于或等于2个的情况下,探测触发帧的发送方式和第二PPDU的发送方式可以包括:As another example, the number of sensing response terminals may be greater than or equal to 2. In the case where the number of sensing response terminals is greater than or equal to 2, the transmission mode of the detection trigger frame and the transmission mode of the second PPDU may include:
作为一个示例,感知发起端在不同时刻分别向多个感知响应端发送探测触发帧,探测触发帧的接收地址可以为对应的感知响应端的地址。感知响应端在不同时刻发送第二PPDU。比如,感知发起端可以在第一时刻向感知响应端1发送探测触发帧,该探测触发帧的地址可以为该感知响应端1的地址,该探测触发帧包括感知发起端为感知响应端1分配的测量资源。该感知响应端1在低频上接收到上述探测触发帧之后,可以在高频进行信道竞争获得TXOP,在该TXOP内,或者在分配的SP内,根据探测触发帧中分配的测量资源发送第二PPDU。该感知响应端1可以在高频发送一个或多个第二PPDU,如可以在不同方向上发送一个或多个第二PPDU。示例性的,前述一个或多个第二PPDU可以属于同一个TXOP或SP。感知发起端在高频上完成与感知响应端1的感知测量之后,该感知发起端可以切换到低频,在低频上进行信道竞争获得TXOP,在该TXOP内,或者在分配的SP内,在低频向感知响应端2发送探测触发帧,该探测触发帧的地址可以为感知响应端2的地址,该探测触发帧包括感知发起端为感知响应端2分配的测量资源。类似的,感知响应端2发送第二PPDU的方式可以参考上述感知响应端1的描述,此处不再赘述。图5中所示的发送方式仅为示例,不应将其理解为对本申请实施例的限定。As an example, the sensing initiator sends a detection trigger frame to multiple sensing responders at different times, and the receiving address of the detection trigger frame can be the address of the corresponding sensing responder. The sensing responder sends the second PPDU at different times. For example, the sensing initiator can send a detection trigger frame to the sensing responder 1 at the first time. The address of the detection trigger frame can be the address of the sensing responder 1, and the detection trigger frame includes the measurement resources allocated by the sensing initiator to the sensing responder 1. After receiving the above-mentioned detection trigger frame at a low frequency, the sensing responder 1 can perform channel competition at a high frequency to obtain a TXOP, and send a second PPDU within the TXOP or within the allocated SP according to the measurement resources allocated in the detection trigger frame. The sensing responder 1 can send one or more second PPDUs at a high frequency, such as sending one or more second PPDUs in different directions. Exemplarily, the aforementioned one or more second PPDUs can belong to the same TXOP or SP. After the perception initiator completes the perception measurement with the perception responder 1 at the high frequency, the perception initiator can switch to the low frequency, perform channel competition at the low frequency to obtain a TXOP, and send a detection trigger frame to the perception responder 2 at the low frequency within the TXOP or within the allocated SP. The address of the detection trigger frame can be the address of the perception responder 2, and the detection trigger frame includes the measurement resources allocated by the perception initiator to the perception responder 2. Similarly, the manner in which the perception responder 2 sends the second PPDU can refer to the description of the perception responder 1 above and will not be repeated here. The sending method shown in Figure 5 is only an example and should not be understood as limiting the embodiments of the present application.
作为另一个示例,感知发起端向多个感知响应端同时发送探测触发帧,该探测触发帧的接收地址为广播地址。比如,该探测触发帧中可以包括感知发起端为感知响应端1分配的测量资源,以及感知发起端为感知响应端2分配的测量资源。As another example, the sensing initiator simultaneously sends a detection trigger frame to multiple sensing responders, where the receiving address of the detection trigger frame is a broadcast address. For example, the detection trigger frame may include measurement resources allocated by the sensing initiator to sensing responder 1 and measurement resources allocated by the sensing initiator to sensing responder 2.
作为又一个示例,感知发起端可以向多个感知响应端同时发送探测触发帧,该探测触发帧的接收地址为各个感知响应端的地址。比如,感知发起端向感知响应端1发送的探测触发帧的接收地址可以是该感知响应端1的地址,该探测触发帧帧可以包括感知发起端为该感知响应端1分配的测量资源等。前述多个感知响应端在接收到探测触发帧之后,这些感知响应端可以在高频上进行信道竞争获得TXOP或在分配的SP内,以MU的形式发送第二PPDU。比如为降低或避免干扰,感知发起端可以将不同的感知响应端调度到不同的资源(如不同的RU或MRU或DRU或不同的方向等)上发送第二PPDU。As another example, the perception initiator can send a detection trigger frame to multiple perception responders at the same time, and the receiving address of the detection trigger frame is the address of each perception responder. For example, the receiving address of the detection trigger frame sent by the perception initiator to the perception responder 1 can be the address of the perception responder 1, and the detection trigger frame can include the measurement resources allocated by the perception initiator to the perception responder 1, etc. After the aforementioned multiple perception responders receive the detection trigger frame, these perception responders can compete for channels at high frequencies to obtain TXOPs or send a second PPDU in the form of MUs within the allocated SPs. For example, in order to reduce or avoid interference, the perception initiator can schedule different perception responders to different resources (such as different RUs or MRUs or DRUs or different directions, etc.) to send the second PPDU.
关于探测触发帧的发送方式可以参考上述方式3或方式4,关于第二PPDU的发送方式可以参考上述方式8,此处不再一一详述。Regarding the method for sending the detection trigger frame, reference may be made to the above method 3 or method 4, and regarding the method for sending the second PPDU, reference may be made to the above method 8, which will not be described in detail here.
(4A)报告阶段:感知发起端在第一频段发送报告触发帧,对应的,感知响应端在第一频段接收该报告触发帧。感知响应端在第一频段发送报告帧,对应的,感知发起端在第一频段接收该报告帧。(4A) Reporting phase: The sensing initiator sends a report trigger frame in the first frequency band, and the sensing responder receives the report trigger frame in the first frequency band. The sensing responder sends a report frame in the first frequency band, and the sensing initiator receives the report frame in the first frequency band.
在报告阶段所在的感知测量交互中包括(3A)所示的TF探测阶段的情况下,感知发起端在高频上接收完第二PPDU之后,可以切换到低频。感知发起端可以在低频上进行信道竞争获得TXOP,或分配的SP内,向一个或多个感知响应端发送报告触发帧。In the case where the perception measurement interaction in which the reporting phase is located includes the TF detection phase shown in (3A), the perception initiator can switch to the low frequency after receiving the second PPDU on the high frequency. The perception initiator can perform channel contention on the low frequency to obtain a TXOP, or send a report trigger frame to one or more perception responders within the allocated SP.
在报告阶段所在的感知测量交互中包括(2A)所示的NDPA探测阶段的情况下,不包括(3A)所示的TF探测阶段的情况下,感知发起端在高频上发送完第一PPDU之后,可以切换到低频。感知发起端可以在低频上进行信道竞争获得TXOP,或分配的SP内,向一个或多个感知响应端发送报告触发帧。同理,此处关于感知发起端的说明同样适用于感知响应端。In the case where the perception measurement interaction in which the reporting phase is located includes the NDPA detection phase shown in (2A) and does not include the TF detection phase shown in (3A), the perception initiator can switch to the low frequency after sending the first PPDU on the high frequency. The perception initiator can compete for the channel on the low frequency to obtain a TXOP, or send a report trigger frame to one or more perception responders within the allocated SP. Similarly, the description of the perception initiator here also applies to the perception responder.
作为一个示例,感知发起端可以分别向多个感知响应端发送报告触发帧,该报告触发帧的接收地址可以为对应的感知响应端的地址。由此,感知发起端可以通过逐一触发的方式触发感知响应端发送报告帧。As an example, the perception initiator can send a report trigger frame to each of the multiple perception responders, and the receiving address of the report trigger frame can be the address of the corresponding perception responder. Thus, the perception initiator can trigger the perception responder to send a report frame by triggering it one by one.
作为另一个示例,感知发起端可以向多个感知响应端发送报告触发帧,该报告触发帧的接收地址可以为广播地址。由此,感知响应端可以通过MU的形式发送报告帧。As another example, the sensing initiator may send a report trigger frame to multiple sensing responders, and the receiving address of the report trigger frame may be a broadcast address. Thus, the sensing responder may send the report frame in the form of MU.
关于(4A)所示的报告触发帧的发送方式可以参考上文方式1或方式2,此处不再详述。Regarding the method of sending the report trigger frame shown in (4A), reference may be made to the above method 1 or method 2, which will not be described in detail here.
通常来说,感知发起端(或感知响应端)不进行频段切换的情况下,感知发起端(或感知响应端)在低频上传输的信号可以属于同一个TXOP,或一个SP;或者,感知发起端(或感知响应端)在高频上传输的信号可以属于同一个TXOP,或同一个SP。举例来说,图5中,感知发起端在低频发送轮询帧,以及在低频接收CTS-to-self帧,因此该轮询帧和该CTS-to-self帧可以属于同一个TXOP或一个SP。又举例来说,图5中,感知发起端在低频发送报告触发帧,以及在低频接收报告帧,因此该报告触发帧和该报告帧可以属于同一个TXOP或一个SP。可选地,不进行频段切换的情况下,感知发起端在低频上传输的不同信号也可能属于不同的TXOP,本申请对此不作限定。Generally speaking, when the perception initiator (or perception responder) does not switch the frequency band, the signal transmitted by the perception initiator (or perception responder) at the low frequency may belong to the same TXOP, or an SP; or, the signal transmitted by the perception initiator (or perception responder) at the high frequency may belong to the same TXOP, or the same SP. For example, in Figure 5, the perception initiator sends a polling frame at a low frequency and receives a CTS-to-self frame at a low frequency, so the polling frame and the CTS-to-self frame may belong to the same TXOP or an SP. For another example, in Figure 5, the perception initiator sends a report trigger frame at a low frequency and receives a report frame at a low frequency, so the report trigger frame and the report frame may belong to the same TXOP or an SP. Optionally, when the frequency band is not switched, different signals transmitted by the perception initiator at the low frequency may also belong to different TXOPs, which is not limited in this application.
可选地,上述轮询帧、CTS-to-self帧、报告触发帧和报告帧也可能在同一个TXOP中完成。由此,从高频切换到低频的情况下,感知发起端(或感知响应端)可以不进行信道竞争接入。可选地,感知发起端(或感知响应端)从低频切换到高频或者从高频切换到低频的情况下,也可以重新竞争信道以获取TXOP。Optionally, the polling frame, CTS-to-self frame, report trigger frame, and report frame may be completed in the same TXOP. Thus, when switching from a high frequency to a low frequency, the sensing initiator (or sensing responder) may not compete for channel access. Optionally, when switching from a low frequency to a high frequency or vice versa, the sensing initiator (or sensing responder) may re-compete for the channel to obtain a TXOP.
此处关于TXOP或SP的说明,下文同样适用。对于TXOP或SP的说明,下文不再详述。The description of TXOP or SP here also applies to the following text, and the description of TXOP or SP will not be further described below.
本申请实施例中,除了第一PPDU和第二PPDU在高频传输(如发送或接收)之外,其他的控制帧均是在低频上传输,从而有效保证了这些控制帧传输的稳定性和抗遮挡性,提高控制帧的发送效率,保证感知测量的顺利进行,同时利用高频上的大带宽进行测量,提高了感知性能。In an embodiment of the present application, except for the first PPDU and the second PPDU transmitted at high frequency (such as sending or receiving), other control frames are transmitted at low frequency, thereby effectively ensuring the stability and anti-obstruction of the transmission of these control frames, improving the transmission efficiency of the control frames, ensuring the smooth progress of perception measurement, and at the same time utilizing the large bandwidth at high frequency for measurement, thereby improving perception performance.

The sensing initiator sends a first PPDU for sensing in the second frequency band, and the sensing responder receives the first PPDU in the second frequency band.

(3B)TF探测阶段:感知发起端在第二频段发送探测触发帧,对应的,感知响应端在第二频段接收该探测触发帧。感知响应端在第二频段发送用于感知的第二PPDU,对应的,感知发起端在第二频段接收该第二PPDU。(3B) TF detection phase: The sensing initiator sends a detection trigger frame in the second frequency band, and the sensing responder receives the detection trigger frame in the second frequency band. The sensing responder sends a second PPDU for sensing in the second frequency band, and the sensing initiator receives the second PPDU in the second frequency band.
在TF探测阶段所在的感知测量交互中包括(3B)所示的NDPA探测阶段的情况下,感知发起端可以在发送完第一PPDU之后,可以继续在第二频段发送探测触发帧。示例性的,如上文图5中关于TXOP或SP的说明,由于第一PPDU、探测触发帧以及第二PPDU均是在第二频段上传输,因此该第一PPDU、探测触发帧和第二PPDU可以属于同一个TXOP或SP。从而可以减少高频和低频的切换次数,减少信道竞争的次数,减少信道接入的复杂度,从而减少感知流程的复杂度。In the case where the perception measurement interaction in the TF detection phase includes the NDPA detection phase shown in (3B), the perception initiator can continue to send the detection trigger frame in the second frequency band after sending the first PPDU. For example, as described above in FIG5 on TXOP or SP, since the first PPDU, the detection trigger frame and the second PPDU are all transmitted on the second frequency band, the first PPDU, the detection trigger frame and the second PPDU can belong to the same TXOP or SP. This can reduce the number of high-frequency and low-frequency switching times, reduce the number of channel contentions, reduce the complexity of channel access, and thus reduce the complexity of the perception process.
在TF探测阶段所在的感知测量交互中包括(1B)所示的轮询阶段,不包括(2B)所示的NDPA探测阶段的情况下,感知发起端在低频接收到CTS-to-self帧之后,可以切换到高频,在高频上发送探测触发帧。示例性的,轮询帧、CTS-to-self帧、探测触发帧可以属于同一个TXOP或SP。同理,此处关于感知发起端的说明同样适用于感知响应端。In the case where the perception measurement interaction in which the TF detection phase is located includes the polling phase shown in (1B) but does not include the NDPA detection phase shown in (2B), the perception initiator can switch to high frequency after receiving the CTS-to-self frame at low frequency and send a detection trigger frame at high frequency. Exemplarily, the polling frame, CTS-to-self frame, and detection trigger frame can belong to the same TXOP or SP. Similarly, the description of the perception initiator here also applies to the perception responder.
如感知发起端可以在不同时刻分别向多个感知响应端发送探测触发帧,探测触发帧的接收地址可以为对应的感知响应端的地址。感知响应端可以在不同时刻发送第二PPDU。又如感知发起端可以在同一时刻发送探测触发帧,该探测触发帧的接收地址可以为广播地址,或者为对应的感知响应端的地址。感知响应端可以通过MU的方式发送第二PPDU(如参考上述方式8)。关于探测触发帧在高频传输的方式可以参考上文方式5或方式6等,此处不再一一详述。For example, the perception initiator can send a detection trigger frame to multiple perception responders at different times, and the receiving address of the detection trigger frame can be the address of the corresponding perception responder. The perception responder can send a second PPDU at a different time. For another example, the perception initiator can send a detection trigger frame at the same time, and the receiving address of the detection trigger frame can be a broadcast address, or the address of the corresponding perception responder. The perception responder can send the second PPDU in the form of MU (such as referring to the above method 8). Regarding the method of high-frequency transmission of the detection trigger frame, please refer to the above method 5 or method 6, etc., which will not be described in detail here.

The sensing responder sends a report frame in the first frequency band, and the sensing initiator receives the report frame in the first frequency band.

At this time, after the perception initiator receives the second PPDU on the high frequency, it can continue to trigger the perception responder on the high frequency to report the perception measurement results.
作为另一个示例,报告阶段所在的感知测量交互包括(2C)所示的NDPA探测阶段,不包括(3C)所示的TF探测阶段。此时,感知发起端在高频上发送完第一PPDU之后,可以继续在高频上触发感知响应端报告感知测量结果。同理,此处关于感知发起端的说明同样适用于感知响应端。As another example, the perception measurement interaction in the reporting phase includes the NDPA detection phase shown in (2C), but does not include the TF detection phase shown in (3C). In this case, after the perception initiator sends the first PPDU on the high frequency, it can continue to trigger the perception responder on the high frequency to report the perception measurement results. Similarly, the description of the perception initiator here also applies to the perception responder.
感知发起端发送报告触发帧的方式可以参考上述方式5或方式6。如感知发起端可以在不同时刻分别在高频发送报告触发帧(如上述方式6),以及感知响应端在不同时刻分别发送报告帧。如图7所示,感知发起端可以先触发感知响应端1报告感知测量结果,然后触发感知响应端2报告感知测量结果。又如感知发起端可以在高频同时发送报告触发帧(如上述方式5),如感知发起端可以向不同的方向发送报告触发帧,保证前述多个感知响应端可以接收到该报告触发帧,该报告触发帧的接收地址可以为广播地址,也可以为对应的感知响应端的地址。感知响应端可以通过MU的方式发送报告帧。The manner in which the perception initiator sends a report trigger frame may refer to the above-mentioned manner 5 or manner 6. For example, the perception initiator may send a report trigger frame at a high frequency at different times (such as the above-mentioned manner 6), and the perception responder may send a report frame at different times. As shown in Figure 7, the perception initiator may first trigger the perception responder 1 to report the perception measurement result, and then trigger the perception responder 2 to report the perception measurement result. For another example, the perception initiator may send a report trigger frame at a high frequency at the same time (such as the above-mentioned manner 5), and the perception initiator may send a report trigger frame in different directions to ensure that the aforementioned multiple perception responders can receive the report trigger frame. The receiving address of the report trigger frame may be a broadcast address or the address of the corresponding perception responder. The perception responder may send a report frame in the manner of MU.

At the same time, the large bandwidth on the high frequency is used for measurement, thereby improving perception performance.

One or more first PPDUs can be sent at the same time, and the embodiments of the present application are not limited to this. For another example, the perception initiator can send NDPA frames in different directions at high frequencies to ensure the smooth reception of NDPA frames. For another example, when the NDPA frame is set to silence other surrounding nodes (NAV) (that is, other nodes are in a silent state), the perception initiator can also send the NDP frame in all directions. The two NDPA frames shown in Figure 8 are only examples and should not be understood as limitations on the embodiments of the present application.

The perception initiator (or responder) does not need to perform additional channel switching, reducing the complexity of channel access. This effectively ensures the efficiency of perception measurements and reduces the complexity of perception measurements.

可理解,图5~图10的附图中所示的各个帧的传输方式仅为示例,不应将附图中示出的方式理解为对本申请的限定。It is understandable that the transmission methods of the various frames shown in the drawings of FIG. 5 to FIG. 10 are merely examples, and the methods shown in the drawings should not be understood as limiting the present application.
图10是本申请实施例提供的non-TB感知测量交互的流程示意图。如图10所示,non-TB感知测量交互的流程可以如下所示:FIG10 is a flow diagram of a non-TB perception measurement interaction provided by an embodiment of the present application. As shown in FIG10 , the flow of the non-TB perception measurement interaction may be as follows:
在non-TB感知测量交互中,STA作为感知发起端,可以发送感知NDPA帧,在预定的间隔时长(如SIFS)之后发送SI2SR NDP。AP作为感知响应端,在SIFS之后发送SR2SI NDP,并在SIFS之后进行报告阶段,AP将测量到的感知测量结果包含在感知测量报告帧中,从而上报给感知发起端。In non-TB sensing measurement interactions, the STA, as the sensing initiator, can send a sensing NDPA frame and, after a predetermined interval (e.g., SIFS), a SI2SR NDP. The AP, as the sensing responder, sends an SR2SI NDP after the SIFS. After the SIFS, the AP enters the reporting phase, where it includes the sensing measurement results in a sensing measurement report frame and reports them to the sensing initiator.
示例性的,AP报告的感知测量结果可以是基于SI2SR NDP得到的感知测量结果,如包括STA到AP的CSI。AP通过发送SR2SI NDP,STA接收到该SR2SI NDP之后,可以基于该SR2SI NDP获得感知测量结果,如包括AP到STA的CSI。For example, the perception measurement results reported by the AP may be perception measurement results obtained based on the SI2SR NDP, such as the CSI from the STA to the AP. The AP sends the SR2SI NDP, and after the STA receives the SR2SI NDP, it may obtain the perception measurement results based on the SR2SI NDP, such as the CSI from the AP to the STA.
在non-TB感知测量交互中,STA可以通过感知NDPA帧灵活地指示STA到AP的感知测量信息或AP到STA的感知测量信息。感知测量信息可以包括但不限于感知PPDU的发送波束的信息、接收波束的信息、空间流信息、发送功率信息或字段的重复次数等信息。当感知NDPA帧指示了STA到AP的感知测量信息时,感知发起端可以在不同方向上向感知响应端发送SI2SR NDP。当感知NDPA帧指示了AP到STA的感知测量信息时,感知响应端可以在不同方向上向感知发起端发送SR2SI NDP。SI2SR NDP或SR2SI NDP的发送方向可以由发送波束确定。示例性的,发送波束可以由第一个波束索引(firstbeamindex)字段或每交互的波束数量(numberofbeamperexchange)字段中的至少一项确定。如第一个波束索引字段可以承载于感知NDPA帧中。每交互的波束数量(number of beam per exchange)字段可以承载于感知测量请求帧中。感知测量请求帧中还可以包括发送波束列表,通过上述第一个波束索引字段和每交互的波束数量字段感知发送端可以用于从发送波束列表中确定具体的波束索引,以及通过该波束索引从波束描述字段(或波束描述元素)中确定具体的波束。对于发送波束的具体确定方法,本申请实施例不作限定。In non-TB sensing measurement exchanges, STAs can flexibly indicate sensing measurement information from the STA to the AP or from the AP to the STA using the Sensing NDPA frame. This sensing measurement information may include, but is not limited to, information about the transmit beam, receive beam, spatial stream, transmit power, or field repetition count of the sensing PPDU. When the Sensing NDPA frame indicates sensing measurement information from the STA to the AP, the sensing initiator may send SI2SR NDPs to the sensing responder in different directions. When the Sensing NDPA frame indicates sensing measurement information from the AP to the STA, the sensing responder may send SR2SI NDPs to the sensing initiator in different directions. The transmission direction of the SI2SR NDP or SR2SI NDP may be determined by the transmit beam. For example, the transmit beam may be determined by at least one of the first beam index field or the number of beam exchange fields. For example, the first beam index field may be carried in the Sensing NDPA frame. The number of beams per exchange field may be carried in the Sensing Measurement Request frame. The perception measurement request frame may also include a transmit beam list. The perception transmitter may use the first beam index field and the number of beams per interaction field to determine a specific beam index from the transmit beam list, and use the beam index to determine a specific beam from the beam description field (or beam description element). The specific method for determining the transmit beam is not limited in this embodiment of the present application.
如当不进行STA到AP的感知测量时,也即,感知NDPA帧未指示STA到AP的感知测量信息时,SI2SR NDP可以是一个预定的NDP,此时AP可以不发送感知测量报告帧。当不进行AP到STA的感知测量时,也即感知NDPA帧未指示AP到STA的感知测量信息时,SR2SI NDP也可以是一个预定的NDP。上述预定的NDP可以认为空口时间小于或等于某一阈值。对于该阈值的具体值,本申请实施例不作限定。该预定的NDP可以单方向传输,如AP或STA可以不进行多方向扫描,而是在一个方向上发送该预定的NDP。或者,该预定的NDP可以满足如下至少一项:该NDP中的SR2SI空时流数(number of space-time streams,NSTS)(或为SR2SI空间流数(numberofspatialstreams,NSS)字段可以设置为0,该NDP中的SR2SI重复(SR2SI rep)字段设置为0。或者,该预定的NDP可以满足如下至少一项:该NDP中的SI2SR NSTS(或为SI2SR NSS)字段设置为0,该NDP中的SI2SR重复(SI2SR rep)字段设置为0。For example, when STA-to-AP perception measurement is not performed, that is, when the perception NDPA frame does not indicate STA-to-AP perception measurement information, the SI2SR NDP may be a predetermined NDP, and the AP may not send a perception measurement report frame. When AP-to-STA perception measurement is not performed, that is, when the perception NDPA frame does not indicate AP-to-STA perception measurement information, the SR2SI NDP may also be a predetermined NDP. The above-mentioned predetermined NDP may be considered that the air interface time is less than or equal to a certain threshold. The specific value of the threshold is not limited in the embodiment of the present application. The predetermined NDP can be transmitted in a single direction, such as the AP or STA may not perform multi-directional scanning, but send the predetermined NDP in one direction.

In other words, the NDPA frame can be used to complete at least one of the configurations of SI2SR NDP or SR2SI NDP.

作为又一个示例,如图14c所示,NDPA帧可以用于配置第二PPDU。此时,步骤(3I)可以包括步骤(b)。图14c是以没有报告阶段为例示出的。如感知响应端通过上层(如MAC层和PHY层之外的协议层)进行感知结果的报告。As another example, as shown in Figure 14c, an NDPA frame can be used to configure the second PPDU. In this case, step (3I) can include step (b). Figure 14c illustrates an example in which there is no reporting phase. For example, the sensing responder reports the sensing results through an upper layer (e.g., a protocol layer other than the MAC layer and the PHY layer).
作为一种可能的实现方式,多个感知响应端可以以MU的形式发送第二PPDU。As a possible implementation manner, multiple perception responders may send the second PPDU in the form of MUs.

举例来说,NDPA帧可以包括STA信息字段(STA info),该STA信息字段可以包括用于为该字段标识的感知响应端分配空间流信息。比如,该STA信息字段可以包括SS分配/随机接入资源单元(random access resource unit,RU-RA)信息字段,该SS分配/RU-RA信息字段可以用于承载上述空间流信息。该空间流信息可以包括空间流数或空间流的标识等信息。For example, an NDPA frame may include a STA information field (STA info), which may include information about the spatial streams allocated to the sensing responder identified by the field. For example, the STA info field may include an SS allocation/random access resource unit (RU-RA) information field, which may be used to carry the aforementioned spatial stream information. The spatial stream information may include information such as the number of spatial streams or the identifier of a spatial stream.
又举例来说,NDPA帧可以STA信息字段(STA info),该STA信息字段可以包括上行(uplink,UL)目标接收功率(UL target receive power)字段,该UL上行接收功率字段可以用于承载上述发送功率信息。或者说,该UL上行接收功率字段可以用于为STA信息字段所标识的感知响应端指示其在发送第二PPDU时,感知发起端期望的接收功率(或期望收到的第二PPDU的功率)。For another example, the NDPA frame may include a STA information field (STA info), which may include an uplink (UL) target receive power (UL target receive power) field. The UL uplink receive power field may be used to carry the aforementioned transmit power information. Alternatively, the UL uplink receive power field may be used to indicate to the sensing responder identified by the STA info field the receive power expected by the sensing initiator (or the power of the second PPDU expected to be received) when transmitting the second PPDU.
上述STA信息字段的关联标识(associated ID,AID)可以小于2008。对于上述SS分配/RU-RA信息字段或UL目标接收功率字段的名称或占用的比特数,本申请实施例不作限定。如前述两个字段占用的比特数可以灵活调整,对于字段占用的比特数,本申请实施例不作限定。这两个字段的使用思路可以参考相关标准或协议等,本申请实施例不作进一步描述。The associated ID (AID) of the STA information field may be less than 2008. The present embodiment does not limit the name or number of bits of the SS allocation/RU-RA information field or the UL target received power field. As the number of bits occupied by the two aforementioned fields can be flexibly adjusted, the present embodiment does not limit the number of bits occupied by the fields. The use of these two fields can be referred to relevant standards or protocols, and will not be further described in the present embodiment.
作为另一种可能的实现方式,多个感知响应端也可以以SU的形式发送第二PPDU。As another possible implementation manner, multiple perception responders may also send the second PPDU in the form of SU.

举例来说,NDPA帧可以包括STA信息字段,该STA信息字段可以包括SR2SI NSTS字段或SR2SI Rep字段中的至少一项。该SR2SI NSTS字段用于指示感知响应端发送第二PPDU时所采用的空间流数,SR2SI Rep字段用于指示感知响应端发送第二PPDU时所采用的LTF重复次数。For example, an NDPA frame may include a STA Information field, which may include at least one of an SR2SI NSTS field or an SR2SI Rep field. The SR2SI NSTS field is used to indicate the number of spatial streams used by the perception responder when sending the second PPDU, and the SR2SI Rep field is used to indicate the number of LTF repetitions used by the perception responder when sending the second PPDU.
上述STA信息字段的AID可以小于2008。对于SR2SI NSTS字段或SR2SI Rep字段的名称或占用的比特数,本申请实施例不作限定。如前述两个字段占用的比特数可以灵活调整。这两个字段的使用思路方法可以参考相关标准或协议等,本申请实施例不作进一步描述。The AID of the STA information field can be less than 2008.

For example, the SI2SR NSTS field may be set to 0. Another example, the SI2SR Rep field may be set to 0. Similarly, when measurements are not performed in the direction from the sensing responder to the sensing initiator (or, in other words, sensing in the SR2SI direction is not performed), that is, when step (3I) does not include step (b), the field used to configure the sensing PPDU (or, referred to as the configuration field) may be set to 0.

That is, the sensing initiator can use this field to instruct the sensing responder, and the sensing initiator sends the first PPDU. If the above field is 1, it can be used to indicate SR2SI sensing (i.e., including step (b)). That is, the sensing initiator can use this field to instruct the sensing responder, and the sensing responder sends the second PPDU.

图15是本申请实施例提供的SBP流程的示意图。如图15所示,STA1作为SBP发起端向AP发送SBP请求帧。AP作为SBP响应端,在收到之后SBP请求帧(如图15简称为SBP请求)之后,会根据SBP请求帧中携带的参数与相应的感知响应端进行感知建立,完成测量并进行反馈。如AP在接收到SBP请求帧之后回复SBP响应帧(如图15简称为SBP响应),该AP可以作为感知发起端发起感知测量会话,如AP可以分别向STA1和STA2发送感知测量请求帧。上述AP作为感知发起端发起的感知测量交互一般是TB感知测量交互。关于TB感知测量交互的说明可以参考上文图5~图9,此处不再详述。Figure 15 is a schematic diagram of the SBP process provided in an embodiment of the present application. As shown in Figure 15, STA1, as the SBP initiator, sends an SBP request frame to the AP. As the SBP responder, after receiving the SBP request frame (referred to as SBP request in Figure 15), the AP will establish perception with the corresponding perception responder according to the parameters carried in the SBP request frame, complete the measurement and provide feedback. If the AP replies with an SBP response frame (referred to as SBP response in Figure 15) after receiving the SBP request frame, the AP can initiate a perception measurement session as a perception initiator. For example, the AP can send perception measurement request frames to STA1 and STA2 respectively. The perception measurement interaction initiated by the above-mentioned AP as the perception initiator is generally a TB perception measurement interaction. For the description of the TB perception measurement interaction, please refer to Figures 5 to 9 above, which will not be described in detail here.
图15中,STA1既可以作为SBP发起端发起SBP请求,也可以作为感知响应端参与感知测量会话。然而,在具体实现中,STA1可以作为SBP发起端发起SBP请求,但是不参与由SBP响应端发起的感知测量会话(即STA1可以不是感知响应端)。In Figure 15, STA1 can act as an SBP initiator to initiate SBP requests and participate in a perception measurement session as a perception responder. However, in a specific implementation, STA1 can act as an SBP initiator to initiate SBP requests but not participate in a perception measurement session initiated by an SBP responder (i.e., STA1 may not be a perception responder).
示例性的,SBP流程还可以包括反馈阶段(图15未示出)和关闭阶段(图15未示出)。举例来说,在SBP的反馈阶段,AP作为SBP响应端,可以对SBP感知测量结果进行收集,然后通过SPB报告帧向SBP发起端(如STA1)上报SBP感知测量报告。或者,SBP响应端也可以不发送SBP报告帧,而是通过上层报告SBP感知测量报告。对于SBP感知测量结果的说明下文同样适用。在SBP关闭阶段(图15未示出),SBP发起端可以对已经建立的SBP流程进行关闭。本申请实施例所示的关闭阶段也可以称为终止阶段等,对于各个阶段的具体名称,本申请不作限定。Exemplarily, the SBP process may also include a feedback phase (not shown in FIG15 ) and a closing phase (not shown in FIG15 ). For example, in the feedback phase of SBP, the AP, as the SBP responding end, may collect the SBP perception measurement results, and then report the SBP perception measurement report to the SBP initiating end (such as STA1) through the SPB report frame. Alternatively, the SBP responding end may not send the SBP report frame, but may report the SBP perception measurement report through the upper layer. The following description of the SBP perception measurement results also applies. In the SBP closing phase (not shown in FIG15 ), the SBP initiating end may close the established SBP process. The closing phase shown in the embodiment of the present application may also be referred to as the termination phase, etc. The specific names of the various phases are not limited in this application.
图15所示的AP向STA1或STA2发送的感知测量请求仅为示例,不应将其理解为对本申请实施例的限定。图15中SBP响应与感知测量请求之间的先后顺序,本申请实施例不作限定。关于图15中的感知测量请求和感知测量响应的说明可以参考上文,此处不再详述。The perception measurement request sent by the AP to STA1 or STA2 shown in Figure 15 is merely an example and should not be construed as limiting the embodiments of the present application. The order of the SBP response and the perception measurement request in Figure 15 is not limited in the embodiments of the present application. For the description of the perception measurement request and perception measurement response in Figure 15, please refer to the above and will not be detailed here.
针对SBP发起端,本申请实施例有如下说明:For the SBP initiator, the embodiment of this application has the following description:
A.SBP发起端作为感知响应端参与感知测量,则该SBP发起端在感知测量交互中的行为可以参考上文所示的TB感知测量交互中的感知响应端的行为,此处不再赘述。A. The SBP initiator participates in the perception measurement as a perception responder. The behavior of the SBP initiator in the perception measurement interaction can refer to the behavior of the perception responder in the TB perception measurement interaction shown above, and will not be repeated here.
示例性的,作为感知发起端的SBP响应端在获得感知测量结果之后,可以向SBP发起端上报SBP感知测量报告。或者说,在感知测量交互中的最后一个阶段完成之后,SBP发起端可以接收来自SBP响应端(也即感知发起端)的SBP报告帧(或简称为SBP报告)。For example, after obtaining the perception measurement result, the SBP responder, which serves as the perception initiator, may report an SBP perception measurement report to the SBP initiator. In other words, after the last phase of the perception measurement interaction is completed, the SBP initiator may receive an SBP report frame (or simply, SBP report) from the SBP responder (i.e., the perception initiator).
B.SBP发起端不作为感知响应端,也即SBP发起端不参与由SBP响应端(也即感知发起端)发起的感知测量,则该SBP发起端不参数感知测量交互的任何阶段,但是可以接收来自SBP响应端的SBP报告帧。B. The SBP initiator does not act as a perception responder, that is, the SBP initiator does not participate in the perception measurement initiated by the SBP responder (that is, the perception initiator). The SBP initiator does not participate in any stage of the parameter perception measurement interaction, but can receive the SBP report frame from the SBP responder.
C.SBP发起端是一个与感知发起端没有关联的STA(unassociated STA,USTA),则感知发起端在感知测量交互的轮询阶段对该SBP发起端进行轮询。作为一个示例,SBP发起端作为感知响应端参与由SBP响应端发起的感知测量会话时,感知发起端通过对该SBP发起端进行轮询可以确认该SBP发起端是否能参加该感知测量会话,或是否能接收SBP报告帧。当SBP发起端确认参加感知测量交互,则该SBP发起端在感知测量交互中的行为可以参考上文所示的TB感知测量交互中的感知响应端的行为,此处不再赘述。作为另一个示例,SBP发起端不参与由SBP发起的感知测量会话,也即SBP发起端不是感知响应端时,感知发起端通过对该SBP进行轮询可以确认该SBP发起端是否能接收SBP报告帧。C. If the SBP initiator is an unassociated STA (USTA) with the perception initiator, the perception initiator polls the SBP initiator during the polling phase of the perception measurement interaction. As an example, when the SBP initiator participates in a perception measurement session initiated by the SBP responder as a perception responder, the perception initiator can confirm whether the SBP initiator can participate in the perception measurement session or receive SBP report frames by polling the SBP initiator. When the SBP initiator confirms participation in the perception measurement interaction, the behavior of the SBP initiator in the perception measurement interaction can refer to the behavior of the perception responder in the TB perception measurement interaction shown above, and will not be repeated here. As another example, when the SBP initiator does not participate in the perception measurement session initiated by the SBP, that is, when the SBP initiator is not a perception responder, the perception initiator can confirm whether the SBP initiator can receive SBP report frames by polling the SBP.
本申请实施例中,无论SBP发起端是否作为感知响应端,感知发起端均可以对该SBP发起端进行轮询。In the embodiment of the present application, regardless of whether the SBP initiator serves as a perception responder, the perception initiator can poll the SBP initiator.
D.SBP发起端是一个与感知发起端有关联的STA,感知发起端在感知测量交互的轮询阶段可以对该SBP发起端进行轮询,也可以不对该SBP发起端进行轮询。D. The SBP initiator is a STA associated with the perception initiator. The perception initiator may or may not poll the SBP initiator during the polling phase of the perception measurement interaction.
结合上文图5~图9,本申请实施例提供了SBP流程的多种示意图。5 to 9 above, the embodiments of the present application provide various schematic diagrams of the SBP process.
图16a和图16b是本申请实施例结合图5所示的感知测量交互提供的一种SBP流程示意图。FIG16a and FIG16b are schematic diagrams of an SBP process provided by an embodiment of the present application in combination with the perception measurement interaction shown in FIG5 .
如图16a所示,感知测量交互中报告阶段中的帧是在第一频段传输的,同时,感知发起端也可以在第一频段发送SBP报告帧。由此可以有效地减少信道竞争获得TXOP的复杂度,减少信道切换的复杂度。图16a中,SBP发起端回复的CTS-to-self帧可以用于指示该SBP发起端可以接收到SBP报告帧。两个感知响应端回复的CTS-to-self帧可以用于指示对应的感知响应端(也即发送该CTS-to-self帧的感知响应端)可以参加感知测量会话。As shown in Figure 16a, the frames in the reporting phase of the perception measurement interaction are transmitted in the first frequency band. At the same time, the perception initiator can also send SBP report frames in the first frequency band. This can effectively reduce the complexity of channel competition to obtain TXOP and the complexity of channel switching. In Figure 16a, the CTS-to-self frame replied by the SBP initiator can be used to indicate that the SBP initiator can receive the SBP report frame. The CTS-to-self frames replied by the two perception responders can be used to indicate that the corresponding perception responder (i.e., the perception responder that sent the CTS-to-self frame) can participate in the perception measurement session.
示例性的,报告阶段中的帧与SBP报告帧可以在同一个频点(或称为频段,如同一个信道或同一条链路)上传输。如该报告阶段中的帧与SBP报告帧可以在同一个TXOP或SP之内。For example, the frames in the reporting phase and the SBP report frame may be transmitted on the same frequency (or frequency band, such as the same channel or the same link), for example, the frames in the reporting phase and the SBP report frame may be within the same TXOP or SP.
关于图16a和图16b的说明可以参考图5或图15等,此处不再赘述。For the description of Figures 16a and 16b, please refer to Figures 5 or 15, etc., and will not be repeated here.

For the description of Figures 17a and 17b, please refer to Figure 6 or Figure 15 or Figure 16a or Figure 16b, etc., and will not be repeated here.
图18a和图18b是本申请实施例结合图7所示的感知测量交互提供的又一种SBP流程示意图。如图18b所示,报告阶段中的帧与SBP报告帧均在第一频段传输,可以有效地减少信道竞争获得TXOP的复杂度,减少信道切换的复杂度。Figures 18a and 18b are schematic diagrams of another SBP process provided by an embodiment of the present application in combination with the perception measurement interaction shown in Figure 7. As shown in Figure 18b, the frames in the reporting phase and the SBP report frame are both transmitted in the first frequency band, which can effectively reduce the complexity of channel contention for obtaining a TXOP and reduce the complexity of channel switching.
示例性的,报告阶段中的帧与SBP报告帧可以同一个TXOP或SP之内。或者说,报告阶段中的帧与SBP报告帧可以在同一个频点上传输。Exemplarily, the frames in the reporting phase and the SBP reporting frames may be within the same TXOP or SP. In other words, the frames in the reporting phase and the SBP reporting frames may be transmitted on the same frequency.
图19a和图19b是本申请实施例结合图8所示的感知测量交互提供的又一种SBP流程示意图。关于图19a和图19b的说明可以参考图8、图15、图16a~图18b等,此处不再赘述。Figures 19a and 19b are another SBP process diagram provided by an embodiment of the present application in combination with the perception measurement interaction shown in Figure 8. For the description of Figures 19a and 19b, please refer to Figures 8, 15, 16a to 18b, etc., and will not be repeated here.
图20a和图20b是本申请实施例结合图9所示的感知测量交互提供的又一种SBP流程示意图。关于图20a和图20b的说明可以参考图8、图15、图16a~图19b等,此处不再赘述。Figures 20a and 20b are schematic diagrams of another SBP process provided by an embodiment of the present application in combination with the perception measurement interaction shown in Figure 9. For the description of Figures 20a and 20b, please refer to Figures 8, 15, 16a to 19b, etc., which will not be repeated here.
本申请实施例中,图16a~图20b所示的SBP流程,可以灵活地实现高低频感知,提升感知效率和感知性能。In the embodiment of the present application, the SBP process shown in Figures 16a to 20b can flexibly realize high and low frequency perception, and improve perception efficiency and perception performance.
以下详细介绍本申请所示的测距通信方法及装置。The following describes in detail the ranging communication method and device shown in this application.
测距发起端(ranginginitiator):发起测距行为的装置;或者,发起高精度定时测量会话(fine timing measurement session,FTM session)的装置;或者,发送初始高精度定时测量请求(initial fine timing measurement request,IFTMR)帧的装置。如该测距发起端可以在低频发送IFTMR帧,或者在高频发送IFTMR帧。上述高精度定时测量会话也可以称为测距测量会话,IFTMR帧也可以称为测距测量请求帧等。测距发起端也可以是测距发送端或测距接收端。Ranging initiator: A device that initiates ranging; or a device that initiates a fine timing measurement session (FTM session); or a device that sends an initial fine timing measurement request (IFTMMR) frame. For example, the ranging initiator can send IFTMR frames at a low frequency or a high frequency. The above-mentioned fine timing measurement session can also be called a ranging measurement session, and the IFTMR frame can also be called a ranging measurement request frame. The ranging initiator can also be a ranging transmitter or a ranging receiver.
测距响应端(rangingresponder):响应测距发起端发起的测距行为,参与到测距的装置。如测距响应端可以接收IFTMR帧,并回复初始高精度定时测量(initial fine timing measurement,IFTM)帧。如测距响应端可以在低频回复IFTM帧,或者在高频回复IFTM帧。示例性的,针对触发的FTM(TB FTM)交互(或称为TB测距测量交互)来说,测距发起端可以为STA,测距响应端可以为AP。示例性的,针对非触发的FTM(non-TB FTM)交互(或称为non-TB测距测量交互)来说,测距发起端可以为STA,测距响应端可以为AP。针对TB FTM会话或non-TB FTM会话的发起端或响应端的具体产品形态,本申请实施例不作限定。测距响应端可以是测距发送端或测距接收端。Ranging Responder: A device that responds to the ranging behavior initiated by the Ranging Initiator and participates in the ranging. For example, the Ranging Responder can receive IFTMR frames and reply with initial fine timing measurement (IFTM) frames.

For example, for a triggered FTM (TB FTM) interaction (or TB ranging measurement interaction), the Ranging Initiator can be an STA and the Ranging Responder can be an AP. For example, for a non-triggered FTM (non-TB FTM) interaction (or non-TB ranging measurement interaction), the Ranging Initiator can be an STA and the Ranging Responder can be an AP.

The Ranging Responder can be a Ranging Transmitter or a Ranging Receiver.
测距发送端(rangingtransmitter):发送测距PPDU的装置。如测距发送端可以在低频发送测距PPDU,或者在高频发送测距PPDU。Ranging transmitter: A device that sends a ranging PPDU. For example, a ranging transmitter can send a ranging PPDU at a low frequency or at a high frequency.
测距接收端(rangingreceiver):接收测距PPDU的装置。如测距接收端可以在低频接收测距PPDU,也可以在高频接收测距PPDU。Ranging receiver: A device that receives ranging PPDUs. For example, a ranging receiver can receive ranging PPDUs at a low frequency or a high frequency.
本申请实施例所示的测距PPDU是用于测距的PPDU,关于该PPDU的格式可以参考上文图2a~图2d等,本申请实施例对于测距PPDU的具体格式不作限定。该测距PPDU的格式可以与感知PPDU的格式相同,也可能存在一些字段的内容不同等,本申请实施例对此不作限定。The ranging PPDU shown in the embodiments of the present application is a PPDU used for ranging. For the format of this PPDU, please refer to Figures 2a to 2d above. This embodiment of the present application does not limit the specific format of the ranging PPDU. The format of the ranging PPDU can be the same as the format of the sensing PPDU, or the content of some fields may differ, etc. This embodiment of the present application does not limit this.

一个测距测量交互可以包括如下四个阶段中的至少一个阶段:轮询阶段、TF探测阶段、NDPA探测阶段或报告阶段。测距测量交互中各个阶段中控制帧的类型可以为测距,感知测量交互中各个阶段中控制帧的类型可以为感知。对于除类型之外的其他信息是否相同,本申请实施例不作限定。下文关于各个控制帧或测距PPDU的传输方式可以参考上文感知测量交互中的描述,下文不再赘述。A ranging measurement interaction may include at least one of the following four phases: a polling phase, a TF detection phase, an NDPA detection phase, or a reporting phase. The type of the control frame in each phase of the ranging measurement interaction may be ranging, and the type of the control frame in each phase of the perception measurement interaction may be perception. Whether other information other than the type is the same is not limited in this embodiment of the present application. For the transmission method of each control frame or ranging PPDU below, please refer to the description in the perception measurement interaction above, and will not be repeated below.
下文通过不同的示例说明本申请所示的测距通信方法。在第二频段为IMMW标准中涉及的频段时,下文示例十~示例十四也可以称为IMMW高低频协作的TB测距测量交互,或IMMW TB测距测量交互,或IMMW高低频混合的TB测距测量交互,或者高低频混合的IMMW TB测距测量交互。为便于描述,下文在涉及具体例子时,将以两个感知响应端为例说明本申请所示的感知通信方法,但是,不应将感知响应端的数量作为对本申请的限定。The following describes the ranging communication method shown in this application through different examples. When the second frequency band is the frequency band involved in the IMMW standard, Examples 10 to 14 below can also be referred to as IMMW high-low frequency collaborative TB ranging measurement interaction, or IMMW TB ranging measurement interaction, or IMMW high-low frequency mixed TB ranging measurement interaction, or high-low frequency mixed IMMW TB ranging measurement interaction. For ease of description, when referring to specific examples below, the perception communication method shown in this application will be described using two perception response terminals as an example. However, the number of perception response terminals should not be used as a limitation to this application.
示例十、Example 10:
图21是本申请实施例提供的TB测距测量交互的一种流程示意图。如图21所示,该TB测距测量交互的流程可以包括:FIG21 is a flow diagram of a TB ranging measurement interaction provided by an embodiment of the present application. As shown in FIG21 , the TB ranging measurement interaction process may include:
(1J)轮询阶段:测距响应端在第一频段发送轮询帧,对应的,测距发起端在第一频段接收该轮询帧。参与交互的测距发起端在第一频段恢复CTS-to-self帧确认自己参加本次测距测量交互。(1J) Polling phase: The ranging responder sends a polling frame in the first frequency band. Correspondingly, the ranging initiator receives the polling frame in the first frequency band. The participating ranging initiator recovers a CTS-to-self frame in the first frequency band to confirm its participation in this ranging measurement interaction.
关于(1J)的说明可以参考上文(1A)的描述,此处不再赘述。For the explanation of (1J), please refer to the description of (1A) above and will not be repeated here.
(2J)TF探测阶段:测距响应端在第一频段发送探测触发帧,对应的,测距发起端在第一频段接收该探测触发帧。测距发起端在第二频段发送用于测距的第二PPDU,对应的,测距响应端在第二频段接收该第二PPDU。(2J) TF Probing Phase: The ranging responder sends a probe trigger frame in the first frequency band. The ranging initiator receives the probe trigger frame in the first frequency band. The ranging initiator sends a second PPDU for ranging in the second frequency band. The ranging responder receives the second PPDU in the second frequency band.
在TF探测阶段所在的测距测量交互包括(1J)所示的轮询阶段的情况下,轮询帧、CTS-to-self帧以及探测触发帧可以位于低频的同一个TXOP内,从而可以有效减少竞争信道的次数,提高测距效率。或者,上述轮询帧、CTS-to-self帧以及探测触发帧可以位于同一个目标唤醒时间(target wake time,TWT)窗口内,或者分配的SP内。In the case where the ranging measurement interaction in the TF detection phase includes the polling phase shown in (1J), the polling frame, CTS-to-self frame, and detection trigger frame can be located in the same low-frequency TXOP, thereby effectively reducing the number of channel contention and improving ranging efficiency. Alternatively, the polling frame, CTS-to-self frame, and detection trigger frame can be located in the same target wake time (TWT) window or the allocated SP.
在测距响应端发送探测触发帧之后,可以切换到第二频段,在第二频段上进行信道竞争,获得TXOP,在该TXOP内发送第二PPDU。或者,测距响应端也可以在分配的SP内在高频上发送第二PPDU。或者,测距响应端也可以在一个TWT窗口内发送第二PPDU。After the ranging responder sends the detection trigger frame, it can switch to the second frequency band, perform channel contention on the second frequency band, obtain a TXOP, and send the second PPDU within the TXOP. Alternatively, the ranging responder can also send the second PPDU on a high frequency within the allocated SP. Alternatively, the ranging responder can also send the second PPDU within a TWT window.
作为一个示例,测距响应端可以在不同时刻分别触发测距发起端发送第二PPDU,也即测距响应端可以在不同时刻分别向测距发起端发送探测触发帧。As an example, the ranging responder may trigger the ranging initiator to send the second PPDU at different times, that is, the ranging responder may send a detection trigger frame to the ranging initiator at different times.
作为另一个示例,测距响应端可以触发不同的测距发起端以MU的形式发送第二PPDU。As another example, the ranging responder may trigger a different ranging initiator to send a second PPDU in the form of an MU.
关于第二PPDU的传输方式,可以参考上文,此处不再详述。Regarding the transmission method of the second PPDU, please refer to the above and will not be described in detail here.
上述探测触发帧也可以称为探测测距触发(soundingrangingtrigger)帧,轮询帧也可以称为轮询测距触发(pollrangingtrigger)或TF测距轮询(TF rangingpoll)帧等,对于各个帧的名称,本申请实施例不作限定。The above-mentioned detection trigger frame can also be called a detection ranging trigger (soundingrangingtrigger) frame, and the polling frame can also be called a polling ranging trigger (pollrangingtrigger) or a TF ranging polling (TF rangingpoll) frame, etc. The names of the frames are not limited in the embodiments of the present application.
(3J)NDPA探测阶段:测距响应端在第一频段发送NDPA帧,对应的,测距发起端在第一频段接收NDPA帧。测距响应端在第二频段发送用于测距的第一PPDU,对应的,测距发起端在第二频段接收该第二PPDU。(3J) NDPA detection phase: The ranging responder sends an NDPA frame in the first frequency band, and the ranging initiator receives the NDPA frame in the first frequency band. The ranging responder sends a first PPDU for ranging in the second frequency band, and the ranging initiator receives the second PPDU in the second frequency band.
关于(3J)的说明可以参考上文(2A)等,此处不再详述。For the description of (3J), please refer to (2A) above, etc., and will not be described in detail here.
(4J)报告阶段:测距响应端在第一频段发送报告帧,对应的,测距发起端接收该报告帧。(4J) Reporting phase: The ranging responding end sends a report frame in the first frequency band, and the ranging initiating end receives the report frame accordingly.
上述测距响应端发送的报告帧也可以称为测距响应端到测距发起端的报告,或者称为发起站点到响应站点位置测量报告(initiating STA to responding STA location measurement report,ISTA to RSTA LMR)。The report frame sent by the ranging responder can also be called a report from the ranging responder to the ranging initiator, or an initiating STA to responding STA location measurement report (ISTA to RSTA LMR).
当测距响应端也需要测距测量结果的情况下,测距响应端可以在第一频段发送报告触发帧,对应的,测距发起端在第一频段接收该报告触发帧。测距发起端在第一频段发送报告帧,对应的,测距响应端在第一频段接收该报告帧。测距响应端触发测距发起端进行报告的步骤是可选的阶段,在测距测量会话的建立阶段,如果测距发起端与测距响应端没有对该步骤进行协商,则该阶段不会出现,也即测距响应端触发测距发起端进行报告的步骤可以不出现。When the ranging responder also needs the ranging measurement result, the ranging responder can send a report trigger frame in the first frequency band, and the ranging initiator accordingly receives the report trigger frame in the first frequency band. The ranging initiator sends a report frame in the first frequency band, and the ranging responder accordingly receives the report frame in the first frequency band. The step in which the ranging responder triggers the ranging initiator to report is an optional stage. During the establishment of the ranging measurement session, if the ranging initiator and the ranging responder do not negotiate this step, this stage will not occur, that is, the step in which the ranging responder triggers the ranging initiator to report may not occur.
上述报告触发帧也可以称为(TF ranging LMR),测距发起端发送的报告帧也可以称为测距发起端到测距响应端的报告(ISTA to RSTA LMR)。The above-mentioned report trigger frame can also be called (TF ranging LMR), and the report frame sent by the ranging initiator can also be called the report from the ranging initiator to the ranging responder (ISTA to RSTA LMR).
关于(4J)的说明可以参考上文(4A)等,此处不再详述。For the description of (4J), please refer to (4A) above, etc., and will not be described in detail here.
