Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It should be noted that “/” in this document means or, for example, A/B can mean A or B; “and/or” in this document is only an association relationship that describes an associated object, indicating that there may be three A relationship, for example, A and/or B, can mean the existence of A alone, the existence of both A and B, and the existence of B alone.

It should be noted that, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to identify the same or similar items that have basically the same function or effect. To distinguish, those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order. For example, the first beam and the second beam are used to distinguish different beams, not to describe a specific order of the beams.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to represent examples, illustrations, or descriptions. Any embodiments or designs described as "exemplary" or "such as" in the embodiments of the present invention should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present the related concepts in a specific manner.

It should be noted that, in the embodiments of the present application, "of", "corresponding (corresponding, relevant)" and "corresponding (corresponding)" may sometimes be used interchangeably. It should be noted that when the difference is not emphasized , its intended meaning is the same. The meaning of "plurality" in the embodiments of the present application refers to two or more.

It should be noted that the signal transmission method provided by the implementation of the present invention can be applied to the scenario of RACH-less handover.

The RACH-less handover includes the following steps:

Step 1: During the mobility process of the terminal device (eg, UE), the terminal device can send the uplink signal in the target cell according to the transmission resource information of the data channel configured by the network device. The network device will indicate the maximum time advance (time advanced, TA) value of the uplink signal sent by the terminal device in the target cell, for example, the TA value is the same as that of the source cell, or the TA value is "0". Specifically, the above-mentioned RACH-less handover may be a target cell handover initiated by the terminal device, or a secondary cell group (Secondary Cell Group, SCG) handover (change) initiated by the terminal device.

Step 2: After receiving the Contention Resolution ID (Contention ResolutionID) information scheduled by the Cell Radio Network Temporary Identifier (C-RNTI) sent by the network device, the terminal device considers that the mobility process is successful. For example, the target cell handover initiated by the terminal device is successful, or the SCG change initiated by the terminal device is successful.

Exemplarily, the network device may configure the terminal device with the sending resource information of the data channel, such as the uplink grant (Uplink Grant, UL grant) of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH). For example, in the case of initiating random access to the network device during the mobility process of the terminal device, the terminal device may send the random access request message carried in the PUSCH to the network device. After receiving the random access request message, the network device may send a random access response message to the terminal device, so that the terminal device can access the network device.

Specifically, the signal transmission method provided by the implementation of the present invention can be applied to a process in which a terminal device and a network device transmit signals on multiple beams, such as a process in which the terminal device receives downlink signals from the network device in multiple beams.

Exemplarily, after the terminal device carries the random access request message in the PUSCH and sends it to the network device, the network device may send the random access response message to the terminal device in multiple beams, so that the terminal device is in the multiple beams. A random access response message is received from a network device.

However, the prior art only supports the terminal device to select a specific beam corresponding to the PRACH resource during the random access process initiated by the terminal device through a physical random access channel (Physical Random Access Channel, PRACH). In the case of sending the random access response message to the terminal device, the random access response message is received from the network device through the downlink channel corresponding to the specific beam. In the process of initiating random access by the terminal device through the PUSCH, the terminal device will not choose to send the random access request message on a specific beam, so the subsequent terminal device cannot determine which beam among the multiple beams the network device sends on. Random access response message. In this way, the terminal device may fail to successfully receive the random access response message sent by the network device.

In response to the above problems, embodiments of the present invention provide a signal transmission method, device, and system, where a terminal device can determine a first beam; and send a first uplink to a network device on a first resource of a first resource set corresponding to the first beam signal, the first uplink signal is the uplink signal carried on the data channel. In this way, the network device can receive the first uplink signal sent by the terminal device on the first beam, and select the first beam from the multiple beams, so as to use the second resource corresponding to the first beam (ie, the second beam) The first downlink signal is sent to the terminal device; further, the terminal device can successfully receive the first downlink signal from the first beam. Therefore, the probability that the terminal device successfully receives the downlink signal in the multi-beam after sending the uplink signal to the network device by using the data channel can be improved.

That is, in the process of initiating random access by the terminal device through the PUSCH, the terminal device can send a random access request to the network device on the PUSCH resource corresponding to the first beam; so that the network device can select the first beam from multiple beams, and send a random access response message to the terminal device on the downlink resource corresponding to the first beam; further, the terminal device can select the first beam from multiple beams, and successfully receive the random access on the first beam. input response message. In this way, it can be solved that in the prior art, when the network device sends a random access response message to the terminal device in multiple beams, the terminal device cannot successfully receive the random access response message sent by the network device, and cannot successfully access the network. equipment problem.

It can include a variety of application scenarios, such as machine to machine (M2M), D2M, macro-micro communication, enhanced mobile Internet (enhance Mobile Broadband, eMBB), ultra-reliable & low-latency communication (ultra Reliable & Low Latency Communication (uRLLC) and Massive Machine Type Communication (mMTC) and other scenarios.

As an example, in the embodiment of the present invention, FIG. 1 shows that the terminal device is a mobile phone as an example.

FIG. 2 shows a schematic flowchart of a signal transmission method provided by an embodiment of the present invention. As shown in FIG. 2 , the signal transmission method may include step 201 and step 202:

Step 201: The terminal device determines the first beam.

Wherein, the terminal device and the network device may transmit signals on multiple beams, and the terminal device may select one beam from the multiple beams to determine to obtain the first beam.

Specifically, a beam may be identified by one or more corresponding signals, and the one or more signals may include at least one of the following: channel state information reference signals (CSI-RS), synchronization signal blocks ( Synchronisation signal block, SSB) (SSB may also be called: SSblock).

Step 202: The terminal device sends a first uplink signal to the network device on the first resource of the first resource set corresponding to the first beam, where the first uplink signal is an uplink signal carried on the data channel.

In an example, after the above step 202, the network device may receive the first uplink signal from the terminal device on the first resource in the first resource set corresponding to the first beam.

It can be understood that the first resource is one resource among one or more resources included in the first resource set, and one or more resources in the first resource set may be data channel transmission resources, that is, uplink resources.

Exemplarily, in this embodiment of the present invention, the data channel may be PUSCH; the resources in the first resource set (eg, the first resource) may be PUSCH resources; the first beam may be a beam corresponding to the PUSCH resource.

Exemplarily, in the process that the terminal device initiates random access to the network device, the first uplink signal may be a random access request message carried on the PUSCH resource.

Optionally, in this embodiment of the present invention, the terminal device may determine the first beam according to information delivered by the network device. Specifically, the above step 201 can be implemented through step 201-1:

Step 201-1: The terminal device determines the first beam according to the target configuration information configured by the network device. The target configuration information is at least used to indicate a first correspondence, and the first correspondence is used to indicate that the first beam corresponds to the first resource set.

It can be understood that, in an example, as shown in FIG. 3 , the signal transmission method provided by the embodiment of the present invention may include step 201a:

Step 201a: The network device configures target configuration information for the terminal device.

The target configuration information is at least used to indicate the first correspondence, the first correspondence is used to indicate that the first beam corresponds to the first resource set, and the first uplink signal on the first resource in the first resource set is on the data channel. bearer uplink signal.

Exemplarily, the above-mentioned step 201a may be performed before the above-mentioned step 202 .

Optionally, the above-mentioned target configuration information includes at least the correspondence between the first beam and the first identifier, and the first identifier is used to indicate the first resource set; wherein, the first identifier is any one of the following: The resource location, the hybrid automatic repeat request (Hybrid Automatic Repeat Req terminal equipment st, HARQ) process identifier corresponding to the resource in the first resource set, and the identifier indicating the configuration information of the first resource set.

Specifically, the following embodiments take three application scenarios as examples to illustrate:

In the first application scenario, the first identifier is the resource location of the resource in the first resource set;

In the second application scenario, the first identifier is the HARQ process identifier corresponding to the resource in the first resource set;

In a third application scenario, the first identifier is an identifier of the configuration information of the first resource set.

Wherein, in the first application scenario and the second application scenario, the network device configures a set of configuration information indicating a resource set for each terminal device in the communication system. In the third application scenario, the network device configures multiple sets of configuration information indicating resource sets for each terminal device in the communication system.

Optionally, the configuration information indicating the first resource set includes resources in the first resource set.

It can be understood that in the case where the first resource set corresponds to the first beam, the terminal device determines the first resource set after determining the first beam, that is, the resources (such as the first resource) that the terminal device can use in the first resource set Send the first uplink signal to the network device. Furthermore, when the network device receives the first downlink signal, it may determine that the first downlink signal is carried on the first resource in the first resource set corresponding to the first beam. In this way, the subsequent network device can send the downlink signal to the terminal device on the downlink resource corresponding to the first beam.

Optionally, the first resource is any resource in the first resource set, the first resource set is any one of at least one resource set, and the at least one resource set is the resource set indicated by the uplink grant configuration information.

The uplink authorization configuration information may be configured by the network device for the terminal device.

Exemplarily, a set of configuration information (such as ulGrantConfig-1) configured by the network device for the terminal device may include multiple PUSCH time-frequency resource information, such as multiple uplink grant configuration information (ie multiple UL grants), each UL grant may include information such as the UL grant resource allocation period, the UL grant starting resource location, and the number of HARQ processes.

Wherein, the process of configuring the target configuration information for the terminal device by the above-mentioned network device is any one of the following two examples:

In an example, during the handover process of the terminal device, the network device may configure the corresponding relationship between the UL grant for accessing the target cell and the beam, that is, the above-mentioned target configuration information, for the terminal device through a Radio Resource Control (RRC) message. When the terminal device performs handover, the terminal device triggers the random access process, and according to the first correspondence indicated by the network device configuration target configuration information, selects the resource (such as the above-mentioned first resource) carrying the random access request message to send the random access request message. A random access request message, and a random access response message can be received in the beam subsequently.

In another example, the network device may trigger the terminal device to initiate a random access process by sending downlink control information (Donwlink Control Information, DCI) information, where the downlink control information indicates the correspondence between the UL grant and the beam, that is, the above-mentioned target configuration information . The terminal device selects a resource bearing the random access request information to send the random access request information according to the target configuration information configured by the network device, and can receive the random access response message on the beam.

It can be understood that, before sending the first uplink signal on the first resource in the first resource set corresponding to the first beam, the terminal device may first select the first resource from the first resource set.

Optionally, the first resource includes any one of the following: a most recently available resource in the first resource set, a recently available resource in the first resource set that is non-consecutive resources, a random resource in the first resource set of continuous resources. A selected resource.

The most recently available resource in the first resource set may be the next available "control information sending resource" starting from the moment when the terminal device triggers the selection of a resource from the first resource set.

The above-mentioned continuous resources may include at least one of the following: time-continuous resources (eg, resources of adjacent slots specified by the protocol), frequency-continuous resources (eg, resources of slots of adjacent physical resource blocks specified by the protocol), Contiguous resources in time and frequency (eg, resources of adjacent slots and adjacent physical resource blocks specified by the protocol).

Optionally, the first resource set includes at least one of the following: resources corresponding to at least one specific time domain location, and resources corresponding to at least one specific frequency domain location.

It can be understood that in the first application scenario, the first resource set includes at least one of resources corresponding to at least one specific time domain location and at least one resource corresponding to at least one specific frequency domain location; while in the second application scenario or the first resource set. In the three application scenarios, the resources in the first resource set are not necessarily resources corresponding to specific time-domain positions or resources corresponding to specific frequency-domain positions.

Exemplarily, the resource corresponding to a specific time domain location may be a PUSCH resource of a specific period (eg, the period is 10 milliseconds).

Exemplarily, the resource corresponding to a specific frequency domain location may be a PUSCH resource corresponding to a specific physical resource block (Physical RB, PRB), a PUSCH resource corresponding to a specific frequency point, or a PUSCH resource corresponding to a specific cell.

Optionally, the target configuration information is used to indicate multiple correspondences, each correspondence is a correspondence between a beam and a resource set, and the first correspondence is one of the multiple correspondences. The above step 202a can be implemented through step 202b:

Step 202b: The terminal device determines the first beam according to the target configuration information and the target rule, and the first beam is the beam whose measurement value is greater than or equal to the measurement threshold value among the multiple beams indicated by the target configuration information.

Wherein, the target rule includes: selecting a beam whose measurement value is greater than or equal to the measurement threshold value.

That is, the terminal device may select the first beam from the multiple beams indicated by the target configuration information to determine the first beam.

Wherein, the measurement value of the above-mentioned beam may be the measurement result of the signal in the beam. Exemplarily, the measurement value of a beam is a measurement result of a reference signal received strength (Reference Signal Received Power, RSRP) of an SSB in the beam. The above measurement threshold value is ssbRSRP-Threshold for the measurement result of the RSRP. Certainly, the measurement value of the beam may also be other measurement results, which are not limited here.

Optionally, in an example, with reference to FIG. 2 , as shown in FIG. 4 , after the foregoing step 202 , step 203 may be further included:

Step 203: The terminal device receives the first downlink signal from the network device on the second resource corresponding to the second beam, and the first beam is the same as the second beam.

The first downlink signal is a signal corresponding to the first uplink signal, a terminal device-specific downlink data channel signal, or a terminal device-specific downlink control channel signal.

Correspondingly, the network device may send the first downlink signal to the terminal device on the second resource corresponding to the second beam.

Wherein, the above-mentioned second resource is a downlink resource.

Exemplarily, in the case where the first downlink signal is a signal corresponding to the first uplink signal, the first downlink signal may be the scheduling information of the random access response message (for example, the PDCCH corresponding to the RAR), or the random access response message. Incoming response message (eg, PDSCH corresponding to RAR). Specifically, the first downlink signal may be feedback information for the first uplink signal, such as C-RNTI scheduling information carried on the PDCCH corresponding to the second beam.

Exemplarily, the terminal device-specific downlink data channel signal may be a signal borne by a terminal device data channel, such as a signal borne by a corresponding PDSCH that the network device subsequently transmits for the terminal device data.

Exemplarily, the terminal device-specific downlink control channel signal may be scheduling information of a terminal device data channel, such as a signal carried by a PDCCH corresponding to a PDSCH corresponding to subsequent terminal device data transmission.

The RAR is a random access response (Random Access Response), the PDCCH is a physical downlink control channel (Physical Downlink Control Channel), and the PDSCH is a physical downlink shared channel (Physical Downlink Shared Channel).

Further optionally, the above-mentioned first downlink signal may include a signal corresponding to the first uplink signal, a terminal device-specific downlink data channel signal, or a terminal device-specific downlink control channel signal.

Optionally, the second beam may correspond to a second resource set, and the second resource set includes the second resource. Similarly, for the process of selecting the second resource from the second resource set by the network device, reference may be made to the above related description of the terminal device selecting the first resource from the first resource set.

Optionally, after the above step 203, steps 204 and 205 may also be included:

Step 204: The terminal device receives target indication information from the network device, where the target indication information is used to indicate that the second beam corresponding to the first downlink signal has been updated to the third beam.

Correspondingly, the network device may send target indication information to the terminal device.

Step 205: The terminal device updates the first target correspondence relationship saved in the terminal device to the second target correspondence relationship according to the target indication information.

The first target correspondence is the correspondence between the second beam and the first downlink signal, and the second target correspondence is the correspondence between the third beam and the first downlink signal.

Optionally, in the case where the terminal device updates the first target correspondence relationship saved in the terminal device to the second target correspondence relationship, the subsequent resources bearing downlink signals may be the same as or different from the second resources.

It can be understood that before the terminal device receives the target indication information, the terminal device receives the downlink signal on the resource corresponding to the second beam (such as the second resource), for example, receives the first downlink signal on the second resource corresponding to the second beam .

In the signal transmission method provided by the embodiment of the present invention, the terminal device can determine the first beam; and send the first uplink signal to the network device on the first resource of the first resource set corresponding to the first beam, and the first uplink signal is a data channel the uplink signal carried on the In this way, the network device can receive the first uplink signal sent by the terminal device on the first beam, and select the first beam from the multiple beams, so as to use the second resource corresponding to the first beam (ie, the second beam) The first downlink signal is sent to the terminal device; further, the terminal device can successfully receive the first downlink signal from the first beam. Therefore, the probability that the terminal device successfully receives the downlink signal in the multi-beam after sending the uplink signal to the network device by using the data channel can be improved.
