Description

Data sending method, data receiving method, data sending device, data receiving device, access point and station
Technical Field
The present invention relates to the field of communications, and in particular, to a data sending method, a data receiving method, an apparatus, an access point, and a station.
Background
With the rapid development of the internet of things industry, a large number of internet of things devices are connected to a network and are connected in a wired or wireless mode, and the internet of things devices are distributed in multiple fields of intelligent transportation, environmental protection, government work, public safety, safe home, intelligent fire fighting, industrial monitoring, old people nursing, personal health, water system monitoring, food traceability and the like. The number of the internet of things devices involved in the application of the internet of things is huge, and the internet of things devices can be called as massive terminals. These terminals are mostly operated by battery power. In most application scenarios, such as water quality monitoring, environmental monitoring and industrial monitoring, the installation site of the equipment is not easy to detect and maintain at any time and replace batteries, and in other scenarios, such as intelligent transportation and electric meter reading, service providers also want the equipment to be installed once, and the batteries do not need to be replaced for months or even years, which requires that the internet of things equipment has a high-performance power-saving mechanism.
In various power saving mechanisms, one of the methods is to add an ultra-low power consumption monitoring and awakening module to the internet of things equipment with wireless communication capability, and the working principle of the monitoring and awakening module is as follows: when the monitoring and waking module is turned on, the device may turn off other modules, such as the sensor module, the microprocessor module, the memory module, the wireless communication module, and so on, and only the monitoring and waking module is kept working, which is hereinafter referred to as the power saving state. The monitoring wakeup module needs to monitor whether a wakeup signal is sent to the monitoring wakeup module, and once the wakeup signal is received, other modules are triggered to work according to the requirement of the wakeup signal, for example, a micro processing module is started, a wireless communication module is started, and the process is called wakeup hereinafter.
The method for providing the service of the Internet of things by utilizing the existing wireless local area network technology is a simple and feasible scheme. With devices commonly found in wireless networks: the above working method is described by taking Access Point (AP) and non-Access Point (non-AP STA) as examples. An AP establishes a Basic Service Set (BSS), an STA is a wireless device associated with the AP, and a monitoring and wake-up module is added to the STA, so that the STA can only keep the monitoring and wake-up module working under the condition of no Service, and is used to receive a wake-up signal. After a period of time, the AP needs to send downlink data to the STA, the AP first sends a wake-up signal to the STA, a monitoring wake-up module of the STA receives the wake-up signal, confirms that the wake-up signal is sent to itself, and then, according to the content of the wake-up signal, starts other modules to perform related operations, for example, receiving downlink data from the AP.
In an internet of things, most stations may be in a power saving state, and when the AP caches data of multiple stations, the AP needs to wake up the multiple stations and perform data transmission. The AP can blindly send the downlink data after a specific time after sending the wake-up signal, but the effective reception of the downlink data by the station cannot be ensured; or after receiving the response of the station to the wake-up signal, the AP may confirm that the master module of the station has entered an awake state and send downlink data to the master module. The method can ensure that downlink data is effectively sent to the awakened station, but how the station quickly and efficiently responds to the awakening signal is a problem to be solved urgently, namely, collision transmission is avoided, and the response speed is increased so that the station can receive the downlink data as soon as possible.

For example, this embodiment provides a wake-up method and apparatus for a power saving device, and specifically, after entering a sleep state, a wireless device only keeps a wake-up monitoring module to monitor a wake-up signal. When the wireless device listens for the wake-up signal, the wireless device needs to notify the wake-up device that its master module has entered an awake state to receive data. In order to perform paging response in time and avoid the situation that efficiency is reduced due to competition collision of a plurality of wireless devices, the data sending method and the data receiving method are provided, so that the wireless devices can perform paging response efficiently, the power-saving mode device can perform data receiving efficiently after entering an awake state, and air interface resources are effectively utilized while saving power.
For the convenience of understanding the above embodiments, the above embodiments will be described in detail with reference to single-user wake-up and paging responses, and multi-user wake-up and paging responses, respectively.
Fig. 4 is a first schematic diagram of single user wake-up and paging response according to an embodiment of the present invention, fig. 5 is a second schematic diagram of single user wake-up and paging response according to an embodiment of the present invention, and the single user wake-up and paging response will be described with reference to fig. 4 and 5.
In a wireless local area network, an AP establishes a BSS. Stations in a wireless local area network are in the coverage area of a certain BSS, are associated with the BSS and communicate with the AP of the BSS. If the station enters the power saving mode, in order to achieve the purpose of saving power and being able to wake up quickly for data communication, the station usually turns off the main module and keeps the power saving monitoring module monitoring the wake-up signal (equivalent to the first wireless signal) sent by the AP. When the AP has the downstream data of the station, the station is first woken up to ensure that the master module of the station enters an awake state and then performs normal communication with the master module.
The AP sends a unicast wake-up signal to a specific station, where the signal carries identification information of the station, where the identification may be a local area identification of the station in the associated BSS, or a unique identification of the station in a paging area, or a combination of the local area identification of the station in the associated BSS and the associated BSS identification. The wake-up signal may also indicate that the wake-up purpose is to send downlink cache data, and further may carry indication information of whether the station is requested to wait for the trigger information after being woken up. When the AP carries and indicates the requesting station to wait for the trigger information after being awakened in the wake-up signal, the AP sends a trigger signal within a period of time after sending the wake-up signal, where the trigger signal may be a unicast or multicast signal. The trigger signal carries the exclusive uplink resource or the random access resource allocated to each station. If the station receives the wake-up signal, the station wakes up the main module of the station, so that the main module enters the awake state from the sleep state, and at least one of the following operations is performed:
operation one: as shown in fig. 4, the master module of the station waits to receive the AP to send a trigger signal. If the received trigger signal allocates a dedicated uplink resource to the station, after a specific Inter-frame space (corresponding to a fourth predetermined time), for example, SIFS (Short Inter frame space, abbreviated as SIFS), after the trigger signal is received, transmitting paging response information on the respective allocated dedicated resource by each of the wakened stations on the allocated plurality of random access points; if uplink random access resources are allocated to the received trigger signal, after a specific Inter Frame Space (IFS) after the trigger signal is received, each awakened station selects one of a plurality of allocated random access Resource Units (RUs) according to a specific condition to send paging response information. The paging response message may be a PS-POLL MAC frame in this example. The MAC frame comprises at least one of the following information: local identification of the station, i.e. association identification aid (associated id), MAC address of the associated BSS, MAC address of the station, and so on. The paging response information may be carried in an uplink multi-user response radio frame, such as an uplink multi-user OFDMA format radio frame.
And operation II: as shown in fig. 5, after a master module of a station enters an awake state, first, a Channel is monitored, and after a radio frame is monitored and a Network Allocation Vector (NAV) is set by time information of the radio frame, or after a specific Probe Delay (Probe Delay) is waited, the station performs Channel Access according to a contention Access mechanism, for example, an Enhanced Distributed Channel Access (EDCA). The site master module may use the highest or higher Access priority, for example, the EDCA Access parameter of the Access priority (AC-VO, or AC-VI) corresponding to the Voice service or the Video service to perform back-off contention. When the backoff is finished, the station sends a paging response wireless frame PS-POLL.
When the AP does not carry the wake-up signal or indicates that the trigger information cannot be sent, the AP waits for the station to send the paging response wireless frame PS-POLL after sending the wake-up signal. And after receiving the wake-up signal, the station sends a paging response wireless frame PS-POLL according to the mode of the operation two.
When the AP indicates that the trigger information is to be sent in the wake-up signal, the station may send the page response radio frame PS-POLL according to the above-mentioned first and/or second operation after receiving the wake-up signal.
Fig. 6 is a first diagram of a multi-user wake-up and paging response according to an embodiment of the present invention, fig. 7 is a second diagram of a multi-user wake-up and paging response according to an embodiment of the present invention, fig. 8 is a third diagram of a multi-user wake-up and paging response according to an embodiment of the present invention, and the following describes the multi-user wake-up and paging response with reference to fig. 6, fig. 7, and fig. 8.
In a wireless local area network, an AP establishes a BSS. Stations in a wireless local area network are in the coverage area of a certain BSS, are associated with the BSS and communicate with the AP of the BSS. If a plurality of stations enter the power saving mode, in order to achieve the purpose of saving power and being awakened quickly for data communication, the stations usually turn off the main module and keep the power saving monitoring module listening to the awakening signal (equivalent to the first wireless signal) sent by the AP. When the AP has downlink data of these stations, it first sends a wake-up signal to ensure that the master modules of these stations enter an awake state and then communicate with them normally.
In order to reduce the overhead of the wake-up signal, the AP may send a multicast wake-up signal to a group of stations, where the signal carries identification information of the group of stations, and the group identification may be a local area identification set or a group identification of the station in an associated BSS, or a unique identification set or a group identification of the station in a paging area, or a combination of a local area identification set and an associated BSS identification of the station in the associated BSS. The wake-up signal may also indicate that the wake-up purpose is to send downlink cache data, and further may also carry indication information of whether the request station waits for the trigger information after being woken up. When the AP carries and indicates to wait for the trigger information after requesting the group of stations to be woken up in the wake-up signal, the AP sends a trigger signal within a period of time after sending the wake-up signal, where the trigger signal may be a unicast or multicast signal. The trigger signal carries a dedicated uplink resource or a random access resource allocated to the station.
If the station receives the wake-up signal, it wakes up its main module to make the main module enter the awake state from the sleep state, and performs the following operations, as shown in fig. 6:
the master module of the station waits to receive the trigger signal sent by the AP. If a special uplink resource is allocated to the station in the received trigger signal, sending a paging response radio frame on the allocated special resource after a specific Inter Frame Space (IFS) after the trigger signal is received; if uplink random access resources are allocated in the received trigger signal, after a specific Inter-frame space (SIFS) is received, for example, after a Short Inter Frame Space (SIFS) is received, one of the allocated plurality of random access Resource Units (RU) is selected according to a specific condition to send a paging response. The page response may be a PS-POLL MAC frame in this example. The MAC frame comprises at least one of the following information: local identification of the station, i.e. association identification aid (associated id), MAC address of the associated BSS, MAC address of the station, and so on. The paging responses of the multiple stations may be carried in an uplink multi-user response radio frame.
When the AP does not carry or indicate that the trigger information is not to be sent in the wake-up signal, after a master module of each station enters an awake state, first monitors a Channel, and when a radio frame is monitored and a Network Allocation Vector (NAV) is set by time information of the radio frame, or after a specific Probe Delay (Probe Delay) is waited, the station performs Channel Access according to a contention Access mechanism, for example, an Enhanced Distributed Channel Access (EDCA). Since the wake-up signal of the AP includes multiple stations, if the high priority access parameter is adopted, the contention window is small, and multiple wakened stations may contend for the channel at the same time to cause collision, as shown in fig. 7. In order to avoid contention collision among a plurality of awakened stations, each station may use a lower Access priority, for example, an EDCA Access parameter of an Access priority (AC-BK, or Access Category _ Best Effort, AC-BE) corresponding to a Background service or a Best Effort service to perform back-off contention. When the backoff of a station is over, the station sends a paging response radio frame PS-POLL, as shown in fig. 8.
It should be noted that the station may respond to the page based on the trigger signal, and the following describes a procedure of responding to the page based on the trigger signal by the station.
For example, according to the above embodiments, the AP sends a wake-up signal to one or more stations. And if the wake-up signal carries and indicates that the requesting station waits for the trigger signal after being awakened, the AP sends the trigger signal a period of time after the wake-up signal. If the AP allocates a dedicated resource to the station in the trigger signal, after a specific inter-frame space IFS after the trigger signal, the station ignores the current physical or virtual channel detection result, that is, directly transmits a paging signal on the allocated resource to respond to the trigger signal of the AP, regardless of whether the channel is idle within the IFS time. If the AP allocates random access resources in the trigger signal, after a specific interframe space IFS after the trigger signal, the station randomly selects a random access resource unit RU according to a specific condition, ignores the current physical or virtual channel detection result, namely directly sends a paging signal on the selected RU to respond to the trigger signal of the AP without considering whether the selected RU channel is idle in the IFS time.
If the AP does not receive a part or all of the paging signals of the designated station within a specific time after the trigger signal, the AP may transmit the wake-up signal and/or the trigger signal for a plurality of times until the maximum number of transmissions or a higher layer is received to notify the awakened station that the station has awakened in another BSS.
For another example, according to the above embodiments, the AP sends a wake-up signal to one or more stations. If the wake-up signal indicates that the wake-up purpose is to send downlink cache data but does not carry the downlink cache data or does not indicate that the requesting station waits for the trigger signal after being woken up, the AP waits for the station to actively contend to send the paging response signal within a period of time after the wake-up signal. If some or all of the paging signals of the designated stations are not received within a specific time, the wake-up signal may be transmitted for a plurality of times until the maximum number of transmissions or a higher layer is received to notify the awakened station that the awakened station has awakened in another BSS. This specific time may be a probe delay time.
As another example, the AP sends a wake-up signal to one or more stations. The wake-up signal includes a service indication bitmap information, which may specifically include at least one of the following information: the method comprises the steps of starting station identification information, a service indication bit map and service indication bit map length information; wherein each bit in the traffic indication bitmap indicates whether the corresponding station has data to transmit. And the station determines the identification range of the group of stations according to the indicated starting station identification information or default starting station identification information and the length of the service indication bitmap. If the identification of the station belongs to the identification range of the station, determining whether the data to be sent is to be sent according to the corresponding bit in the service indication bit mapping diagram, wherein the bit position is '1', the data to be sent is represented, and otherwise, the data to be sent is not represented.
And when the self data to be sent is determined, the station is the awakened station.
When the station receives the wake-up signal and judges that the station is the awakened station, the station waits for receiving the trigger signal by default, and if the trigger signal is not received within the default preset time of the station, the station can actively compete for the channel and send a paging response signal. In order to reduce the concept of contention access collision of a plurality of stations, the stations adopt access parameters corresponding to a lower access level predefined by a system to contend for a channel, such as an AC-BE or AC-BK access level.
For another example, the AP indicates, in the wake-up signal, that the requesting station waits for the trigger signal, and carries predetermined time information to indicate that the awakened station waits for the trigger signal within a predetermined time after receiving the wake-up signal. When the station receives the wake-up signal and judges that the station is the awakened station, the station waits for receiving the trigger signal, and if the trigger signal is not received within the preset time, the station can actively compete for the channel and send a paging response signal. In order to reduce the concept of contention access collision of a plurality of stations, the stations adopt access parameters corresponding to a lower access level predefined by a system to contend for a channel, such as an AC-BE or AC-BK access level.
