[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on August 11, 2023, with application number 202311020970.3 and invention name “Reference Signal Measurement Reporting Method, Device and Storage Medium”. The entire contents of the Chinese patent application are incorporated herein by reference. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a reference signal measurement and reporting method, device, and storage medium. Background Art

[0004] Direct communication can also be called sidelink (SL) communication or short-range communication. In this application, SL communication refers to all types of direct communication. Due to the shortage of spectrum resources, current SL communication needs to consider operating at higher frequencies, such as deployment above 24 GHz. However, operating at high frequencies introduces more problems. For example, high frequencies generally have higher transmission losses, and directional beams are needed to expand coverage.

[0005] In traditional cellular communication networks, a user equipment (UE) generally only needs to communicate with its connected base station (BS), so the UE only needs to perform beam training with the connected BS. However, with SL communication, the UE needs to communicate with many other UEs in its vicinity. If the UE operates at a high frequency, beam training mechanisms such as inter-UE beam measurement reporting need to be considered. Unlike cellular networks, where UEs only perform beam training with the BS, SL communication UEs require beam training between each other. From the perspective of a single UE, the number of required training times and the overhead are significantly increased.

[0006] Generally, the beam training process involves the transmitter sending one or more reference signals (RS), each corresponding to a beam. The receiver measures these RSs and reports the RS measurement results back to the transmitter, allowing the transmitter to determine how its beam is received by the receiver. SL UEs send different RSs for different purposes or uses. However, if a SL UE sends a different RS for each other UE, and also sends different RSs for different purposes or uses for the same UE, the number of RSs that need to be sent is large, resulting in high beam training times and overhead, impacting SL communication efficiency.

[0020] In order to make the application purpose, technical solutions and beneficial effects of this application clearer, the embodiments of this application are described below in conjunction with the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily.

[0021] SL UE sends RS for different purposes or uses, such as:

[0022] Generally, unicast communication between UEs requires establishing a unicast connection. At high frequencies, due to the narrow beamwidth, UEs must first perform initial beam pairing (IBP) to achieve optimal communication. IBP can occur before, during, or after establishing a unicast connection. For example, before establishing a unicast connection, the transmitting UE can send RSs to allow surrounding UEs to discover it and measure its transmitted beams. If other UEs wish to communicate with the transmitting UE, they can use these RSs to complete beam training before establishing a connection.

[0023] After a unicast connection is established, the UE can send an RS to allow the corresponding receiving end to measure and provide feedback for beam maintenance (BM) between the two.

[0024] After a unicast connection is established, in order to promptly detect whether the current working beam is valid, the transmitting UE can send a specific RS to allow the receiving UE to perform beam failure detection (BFD).

[0025] After the unicast connection is established, in order to perform beam recovery as soon as possible after a beam failure occurs, the transmitting UE can send RSs corresponding to alternative beams so that the receiving UE can detect the status of these alternative beams and select a new working beam to perform beam recovery (Candidate Beam Determination, CBD) as soon as possible.

[0026] Generally speaking, SL communication can be divided into two major communication modes. In the first mode (referred to as mode 1), the resources for the UE to send SL signals come from the scheduling of the base station, while in the second mode (referred to as mode 2), the UE autonomously selects resources from the resource pool configured or pre-configured by the network according to the resource selection strategy. The resource selection strategy mainly includes: sensing mechanism, partial sensing mechanism, and random selection mechanism. The above two modes are determined based on the resource allocation strategy when the transmitter sends data, while the above resource allocation strategy is not used for the feedback channel of the RS at the receiver. For example, after the receiver receives the data, the resource location of the feedback channel can be implicitly calculated based on the location information of the data resource.

[0027] Regardless of the above mode, for the RS sent by the transmitting end, the receiving end UE needs to feed back the corresponding beam measurement results, which requires more beam training times and occupies corresponding feedback channel resources.

[0028] FIG1 is a flowchart of a reference signal measurement and reporting method provided in an embodiment of the present application. As shown in FIG1 , the reference signal measurement and reporting method provided in this embodiment includes:

[0029] Step S110: Configure a first reference signal group, where the first reference signal group includes at least one first reference signal, and the first reference signal group has a corresponding measurement purpose. Configure a first parameter corresponding to each first reference signal, where the first parameter is used to determine a feedback channel resource corresponding to the corresponding first reference signal.

[0030] The reference signal measurement and reporting method provided in this embodiment is used to transmit, measure, and feedback a reference signal in SL communication. The reference signal measurement and reporting method provided in this embodiment is applied to the transmitting end, that is, the end that transmits the reference signal in SL communication.

[0031] In order to solve the problem of feedback overhead and resource consumption for RS measurement in SL communication, the reference signal measurement reporting method provided in the embodiment of the present application can use the same RS sent by the transmitting UE for multiple purposes, or be used by different receiving UEs at the same time, thereby reducing the number of beam training times and the resources occupied by the feedback channel. For example:

[0032] For UEs that do not have a unicast connection established, multiple receiving UEs can perform beam training on the same set of RSs sent by the transmitting UE.

[0033] For multiple receiving UEs with unicast connections, the same RS can also be used for measurement. For example, if a transmitting UE sends an RS, multiple receiving UEs with unicast connections to the transmitting UE can be configured to measure the RS simultaneously (i.e., each receiving UE is notified that the RS to be measured is the same RS). This avoids the resource overhead caused by the transmitting UE sending different RSs for different receiving UEs.

[0034] For the same receiving UE, the RS configured for different purposes or uses can also be the same RS. For example, the transmitting UE configures a group of RSs to determine the alternative beam after the beam fails, and configures another group of RSs for beam maintenance, but in fact, some or all of the RSs contained in these two groups of RSs are the same.

[0035] In the case where a single RS can be used for different purposes or applications, or for multiple UEs, the issue of beam measurement feedback needs to be addressed. The receiving UE uses a feedback channel to send beam measurement information, and the feedback channel is implicitly determined by the resources used by the RS. Therefore, if the RS is used by multiple UEs for multiple purposes, the feedback channels corresponding to different purposes of different UEs may conflict, causing the transmitting UE to be unable to receive these conflicting feedback channels. Even if the transmitting UE successfully receives the feedback channel, it cannot distinguish the receiving UE or the purpose of the feedback channel.

[0036] Therefore, in an embodiment of the present application, for one RS, based on the control of the transmitting UE, feedback channels for different purposes or uses and different UEs can correspond to different feedback channel resources to avoid conflicts in feedback channel resources, and enable one RS to be detected by multiple UEs and used for different purposes.

[0037] First, the transmitting UE configures a first reference signal channel resource group. The first reference signal resource group includes at least one first reference signal, and each first reference signal corresponds to a beam. The first reference signal group has a corresponding measurement purpose. Taking the at least one first reference signal in the first reference signal group as a whole, the measurement purpose corresponding to the first reference signal group can be one or more. Then, the transmitting end also configures a first parameter corresponding to each first reference signal in the first reference signal resource group. The first parameter is used to determine the feedback channel resource corresponding to the corresponding first reference signal. The location of the feedback channel resource corresponding to the first reference signal corresponds to the measurement purpose corresponding to the first reference signal. In other words, the first parameter is actually used to indicate the measurement purpose corresponding to the first reference signal. In this way, the transmitting UE can use one or a group of first reference signals to achieve different measurement purposes. By simply using the first reference signal to indicate the feedback channel resource corresponding to different measurement purposes, the transmitting UE can obtain the required measurement results based on the feedback channel resource where the feedback channel is located after receiving the feedback channel of the first reference signal.

[0038] In one embodiment, a reference signal group may correspond to one or more feedback channel resource sets, or each first reference signal in a first reference signal group may correspond to one or more feedback channel resources. A feedback channel resource is determined from the feedback channel resource set or feedback channel resource corresponding to the first reference signal group or the first reference signal based on a first parameter corresponding to the first reference signal group or the first reference signal.

[0039] In the embodiment of the present application, RS is taken as the synchronization channel as an example for illustration. The synchronization signal is also called the sidelink synchronization signal and PSBCH resource block (S-SSB) in SL communication. An S-SSB not only includes a reference signal for measurement, but also includes indication information, such as the physical sidelink broadcast channel (PSBCH). The transmitting UE can send a group of S-SSBs within a cycle, where each S-SSB corresponds to a beam direction. An S-SSB corresponds to a feedback channel resource set. In the embodiment of the present application, the feedback channel is taken as the physical sidelink feedback channel (PSFCH) as an example. The fan library channel resource set corresponding to an S-SSB includes R1 PSFCH channel resources. The feedback channel resource set is determined by the time domain and frequency domain position mapping of the corresponding S-SSB.

[0040] In one example, the network side or the base station side configures an alternative resource set for S-SSB, which includes several basic time domain units in the time domain, and the basic time domain units are subsequently referred to as time slots. These basic time domain units may also repeat with a certain period; the alternative resource set includes M basic frequency domain units in the frequency domain, and the basic frequency domain units are subsequently referred to as resource blocks (RBs) or resource elements (REs). An S-SSB is generally sent on an S-SSB resource, and an S-SSB resource generally refers to N basic frequency domain units on several symbols on a slot, where M is greater than or equal to N, or M is a multiple of N. Similarly, in one example, the network or base station configures a set of candidate resources for the PSFCH. In the time domain, this set of candidate resources generally includes several symbols across several time slots. These time slots with PSFCHs may also repeat periodically. Generally, in the time domain, the symbols used for the PSFCH in a time slot are also called a PSFCH occasion. In the frequency domain, this set includes X basic frequency domain units. A PSFCH is generally transmitted on one PSFCH resource, which generally refers to Y basic frequency domain units across several symbols in one slot, where X is greater than or equal to Y, or is a multiple of Y. In one example, the time slots included in the S-SSB candidate resource set and the time slots included in the PSFCH candidate resource set may correspond to each other. For example, the PSFCH resource will appear in the N2th time slot after every N1 S-SSB time slots, that is, the PSFCH resource will appear in the N2th time slot after the 0th S-SSB resource, and the PSFCH resource will appear in the N2th time slot after the N1th S-SSB resource, and so on. In one example, if the above N2 is equal to 0, the PSFCH time slot is a subset of the S-SSB time slot. For example, the PSFCH resource will appear in the time slot of every N1 S-SSB, that is, the PSFCH resource will appear in the 0th, N1th, and N1*2th S-SSB time slots.

[0041] In one example, in the time domain, if an S-SSB resource is located in time slot n, the corresponding PSFCH resource is located in the first time slot configured with PSFCH resources after time slot n+K. In one example, time slot n+K may also be included after time slot n+K. In one example, if the time slots included in the S-SSB candidate resource set and the time slots included in the PSFCH candidate resource set can have a corresponding relationship, it can be seen that one PSFCH opportunity corresponds to at most N1 S-SSB time slots, and these N1 S-SSB time slots include at most N S-SSB=N1*(M / N) S-SSB resources, and a PSFCH opportunity includes N in the frequency domain PSFCH =X / Y PSFCHs, then one S-SSB resource can correspond to If we consider that a PSFCH resource in a frequency domain can be divided into Z resources by cyclic shift and other codes, then one S-SSB resource corresponds to a PSFCH resource set, which contains R1 PSFCH resources, and R1 is equal to In one example, if the UE's transmission occupies n S-SSB resources, then its corresponding PSFCH resource set may only include the PSFCH resource set corresponding to the starting S-SSB resource, that is, R1 is Or it contains the PSFCH resource set corresponding to all S-SSB resources, that is, R1 is The specific correspondence relationship to be used can be determined by the configuration on the network side or the base station side. In one example, the R1 PSFCH resources can be numbered in sequence, for example, first numbered according to the frequency domain position, and then numbered according to the code domain. For example, the number of a PSFCH resource in R1 is Where i is the code domain number of the PSFCH, and j is the frequency domain number. The numbering can also be performed in the code domain first and then in the frequency domain.

[0042] For a transmitting UE, assuming UE1 is the transmitting UE, when UE1 sends an S-SSB, the S-SSB can be used for measurements of multiple UEs and for multiple purposes. As described above, the S-SSB corresponds to a feedback channel resource set containing R1 PSFCH resources. Each receiving UE determines the PSFCH resource to be used from the feedback channel resource set corresponding to the S-SSB based on its corresponding first parameter.

[0043] In this embodiment, the first parameter is configured by the transmitting end and may be carried in a first reference signal and sent to the receiving end, or the transmitting end may indicate the first parameter to the receiving end through other means. In one embodiment, the first parameter may also be configured on the network side and sent to the receiving end by the network side. The network side may be a network element located in the core network or a base station. Alternatively, the first parameter may be predefined, that is, the transmitting end and the receiving end pre-agreed on the feedback channel resources occupied by feedback channels for different measurement purposes.

[0044] When each first reference signal in the first reference signal group corresponds to one or more feedback channel resource sets, the first parameter is used to determine a resource position of the feedback channel resource corresponding to the first reference signal from the one or more feedback channel resource sets corresponding to the first reference signal. When the first reference signal group corresponds to one or more feedback channel resource sets, the first parameter is used to determine a resource position of the feedback channel resource corresponding to the first reference signal from the one or more feedback channel resource sets corresponding to the first reference signal group.

[0045] The first parameter may include one of the following: a feedback resource identifier, an index of the feedback resource in the feedback channel resource set, or a group member identifier. That is, the first parameter may use the above identifier or index as an indication of the feedback channel resource.

[0046] The measurement purpose corresponding to the first reference signal group includes at least one of the following: for initial beam pairing, for beam maintenance, for beam failure detection, and for determining alternative beams. The following will use specific embodiments to describe in detail the reference signal measurement reporting for different measurement purposes of the first reference signal group.

[0047] The first reference signal group may also include at least one of the following: a feedback channel resource set or a feedback channel resource subset corresponding to the first reference signal group; a device identifier corresponding to at least one first reference signal in the first reference signal group; and a time-frequency position and period of at least one first reference signal in the first reference signal group.

[0048] Step S120: Send at least one first reference signal in the first reference signal group, and receive a first feedback channel on a feedback channel resource corresponding to the at least one first reference signal.

[0049] After configuring the first reference signal resource group, the transmitting end UE sends at least one first reference signal in the first reference signal group. The first reference signal may be used for beam measurement for different purposes. After the receiving end measures the first reference signal during beam detection, it determines the measurement purpose corresponding to the first reference signal, and then places the measurement result of the first reference signal on the feedback channel resource corresponding to the first reference signal indicated by the first parameter to obtain the first feedback channel. The transmitting end will receive the first feedback channel on the feedback channel resource corresponding to the at least one first reference signal sent. The transmitting end also determines the receiving end's measurement result of the first reference signal based on the feedback channel resource where the first feedback channel is received, thereby completing the measurement reporting of the reference signal. Since the transmitting end only configures one reference signal resource group and indicates the feedback channel resources corresponding to different measurement purposes of the first reference signal through the first parameter, reference signal multiplexing is achieved, reference signal resources are saved, and resource conflicts of feedback channels for different purposes are avoided.

[0050] If the first parameter is configured by the transmitting end, the receiving end that obtains the first parameter configuration from the transmitting end sends the feedback channel on the feedback channel resources corresponding to the first reference signal determined by the first parameter configured by the transmitting end. If the first parameter is configured by the network side or is predefined, the receiving end that does not obtain the first parameter configuration from the transmitting end sends the feedback channel on the feedback channel resources corresponding to the first reference signal determined by the predefined or network-configured first parameter.

[0051] It can be seen that even if different receiving UEs measure the same reference signal for different purposes, they can each determine their corresponding feedback channel resources according to their respective configuration information, thereby avoiding feedback channel conflicts.

[0052] In the embodiments of this application, when configuration or pre-configuration is mentioned, it generally refers to: configuration generally comes from the network side, the base station side, or the receiving UE that establishes a connection with the transmitting UE, and is sent to the UE via signaling. Pre-configuration is generally configuration provided by other higher-level entities, such as the UE's own higher-level entities, other network entities, etc. The distinction between configuration and pre-configuration will not be strictly made later, and they will be collectively referred to as configuration. When pre-defined is mentioned, it generally refers to rules or parameters pre-defined by a protocol or standard, which generally do not change.

[0053] In a reference signal measurement reporting method provided in an embodiment of the present application, a transmitting end configures a first reference signal group, where the first reference signal group includes at least one first reference signal and has a corresponding measurement purpose. A first parameter corresponding to each first reference signal is configured, where the first parameter is used to determine a feedback channel resource corresponding to the corresponding first reference signal. The transmitting end then transmits at least one first reference signal in the first reference signal group and receives a first feedback channel on the feedback channel resource corresponding to the at least one first reference signal. A measurement result corresponding to the sequential measurement purpose is determined by receiving the feedback channel resource of the first feedback channel. This allows the same reference signal to be used to achieve different measurement purposes, thereby conserving reference signal resources and avoiding resource conflicts for the reference signal feedback channel.

[0054] FIG2 is a flowchart of another reference signal measurement reporting method provided in an embodiment of the present application. As shown in FIG2 , the reference signal measurement reporting method provided in this embodiment includes:

[0055] Step S210: Detect a first reference signal sent by a transmitting end, determine a first parameter corresponding to the first reference signal, and determine a measurement purpose of the first reference signal.

[0056] The reference signal measurement and reporting method provided in this embodiment is used to transmit, measure, and report reference signals in SL communications. The reference signal measurement and reporting method provided in this embodiment is applied to the receiving end, that is, the end in SL communications that receives the reference signal and reports back the measurement results for the received reference signal.

[0057] The receiving end detects reference signals. Upon detecting a first reference signal sent by the transmitting end, the receiving end further determines a first parameter corresponding to the first reference signal and a measurement objective for the first reference signal. The first reference signal is located in a first reference signal resource group configured by the transmitting end. The first reference signal resource group includes at least one first reference signal, each corresponding to a beam. The first reference signal group has a corresponding measurement objective. Considering the at least one first reference signal in the first reference signal group as a whole, the first reference signal group may correspond to one or more measurement objectives. The first parameter corresponding to the first reference signal may be configured by the transmitting end or the network, or it may be a predefined value. The first parameter is used to determine the feedback channel resource corresponding to the corresponding first reference signal. The location of the feedback channel resource corresponding to the first reference signal corresponds to the measurement objective corresponding to the first reference signal. This allows the transmitting end UE to use one or a group of first reference signals to achieve different measurement objectives. By simply using the first parameter to indicate the feedback channel resource corresponding to each measurement objective, the receiving end can determine the measurement objective and the feedback channel resource to which the measurement results are fed back based on the first reference signal and the first parameter.

[0058] In one embodiment, the first parameter is configured by the transmitting end, and the first parameter may be carried in a first reference signal and sent to the receiving end, or the transmitting end may indicate the first parameter to the receiving end through other means. Alternatively, the first parameter may be configured on the network side and sent by the network side to the receiving end. The network side may be a network element located in the core network or a base station. Alternatively, the first parameter may be predefined, that is, the transmitting end and the receiving end pre-agreed on the feedback channel resources occupied by feedback channels for different measurement purposes.

[0059] The measurement purpose corresponding to the first reference signal includes at least one of the following: for initial beam pairing, for beam maintenance, for beam failure detection, and for determining alternative beams. The following will use specific embodiments to describe in detail the reference signal measurement reporting for different measurement purposes of the first reference signal.

[0060] Step S220: Determine, according to the first parameter, a feedback channel resource corresponding to the first reference signal in the feedback channel resource set corresponding to the first reference signal, and send a first feedback channel for the first reference signal to the transmitting end on the feedback channel resource.

[0061] After receiving the first reference signal and determining the first parameter corresponding to the first reference signal, the receiving end can determine the feedback channel resource corresponding to the first reference signal in the feedback channel resource set corresponding to the first reference signal based on the first parameter. And send the first feedback channel for the first reference signal to the transmitting end on the feedback channel resource. The transmitting end will receive the first feedback channel on the feedback channel resource corresponding to at least one first reference signal sent. The transmitting end also determines the receiving end's measurement result of the first reference signal based on the feedback channel resource where the first feedback channel is received, thereby completing the measurement reporting of the reference signal. Since the transmitting end only configures one reference signal resource group and indicates the feedback channel resources corresponding to different measurement purposes of the first reference signal through the first parameter, reference signal multiplexing is achieved, reference signal resources are saved, and resource conflicts of feedback channels for different purposes are avoided.

[0062] In one embodiment, a reference signal is located in a first reference signal group, which includes at least one first reference signal. The first reference signal group corresponds to one or more feedback channel resource sets, or each first reference signal in the first reference signal group corresponds to one or more feedback channel resource sets. A feedback channel resource is determined from the feedback channel resource set or feedback channel resource corresponding to the first reference signal group or the first reference signal based on a first parameter corresponding to the first reference signal group or the first reference signal.

[0063] When each first reference signal in the first reference signal group corresponds to one or more feedback channel resource sets, a resource position of the feedback channel resource corresponding to the first reference signal is determined in the one or more feedback channel resource sets corresponding to the first reference signal according to the first parameter. When the first reference signal group corresponds to one or more feedback channel resource sets, a resource position of the feedback channel resource corresponding to the first reference signal is determined in the one or more feedback channel resource sets corresponding to the first reference signal group according to the first parameter.

[0064] The first parameter may include one of the following: a feedback resource identifier, an index of the feedback resource in the feedback channel resource set, or a group member identifier. That is, the first parameter may use the above identifier or index as an indication of the feedback channel resource.

[0065] If the first parameter is configured by the transmitting end, the receiving end that obtains the first parameter configuration from the transmitting end determines the feedback channel resource corresponding to the first reference signal from the set of feedback channel resources corresponding to the first reference signal determined based on the first parameter configured by the transmitting end. If the first parameter is configured by the network side or is predefined, the receiving end that does not obtain the first parameter configuration from the transmitting end determines the feedback channel resource corresponding to the first reference signal from the set of feedback channel resources corresponding to the first reference signal determined based on the predefined or network-configured first parameter.

[0066] In the reference signal measurement and reporting method provided in an embodiment of the present application, a receiving end detects a first reference signal sent by a transmitting end, determines a first parameter corresponding to the first reference signal, and determines a measurement purpose of the first reference signal. Then, based on the first parameter, a feedback channel resource corresponding to the first reference signal is determined from a set of feedback channel resources corresponding to the first reference signal, and a first feedback channel for the first reference signal is sent to the transmitting end on the feedback channel resource. This allows the same reference signal to be used to achieve different measurement purposes, conserves reference signal resources, and avoids resource conflicts for the reference signal feedback channel.

[0067] The reference signal measurement reporting method provided in the embodiments of the present application is described in detail below using different specific embodiments.

[0068] Example 1

[0069] First, take the example of a transmitting UE sending a reference signal. The transmitting UE is UE1, the reference signal is an S-SSB, and the feedback channel for the S-SSB is a PSFCH. The S-SSB can be used for measurements of multiple UEs and for various purposes. The S-SSB corresponds to a feedback channel resource set, which includes R1 PSFCH resources. Each receiving UE determines the PSFCH resource to be used from the S-SSB feedback channel resource set based on its corresponding first parameter.

[0070] In one example, a receiving UE, for example UE2, receives an S-SSB, and UE2 wants to establish a unicast connection with UE1. If UE2 wants to complete the initial beam pairing with UE1, UE2 can determine a feedback channel resource in the feedback channel resource set according to the first parameter to send a PSFCH to notify UE1 of the beam status of the S-SSB. In one example, the PSFCH resource used by UE2 is numbered (ID0) mod (R1), where ID0 is the first parameter determined by UE2. In one example, ID0 can be equal to a predefined default value or a configured value, such as 0; or ID0 can be equal to (P ID +M ID ), where P ID One or more physical identifiers indicated in the S-SSB. For example, the S-SSB may carry the identifier corresponding to UE1 and may also carry the target receiving identifier to limit the receiver of the S-SSB. IDIt can be equal to a predefined default value or a configured value, such as 0. It can be seen that UE2 has not yet established a connection with UE1 and cannot obtain configuration information from UE1. The PSFCH resources it uses are not unique to UE2. For example, if another receiving UE, UE3, has not established a connection with UE1, and UE3 also sends PSFCH on the PSFCH resource set corresponding to S-SSB, then the PSFCH resources it uses are the same as those used by UE2. From the perspective of UE1 at this time, if UE1 receives feedback from the PSFCH resource numbered (ID0) mod (R1), it can only determine that there is UE feedback in the S-SSB beam direction, but cannot determine which UE or how many UEs it comes from. At this time, the first parameter can be understood as the default parameter, and its corresponding feedback resource can also be understood as the default resource.

[0071] It should be noted that (ID0) mod (R1) above represents the modulo operation of ID0 with respect to R1. If ID0 is always less than R1, the modulo operation still equals ID0, and the modulo operation can be omitted. In other words, (ID0) mod (R1) described above can be replaced with ID0. This is also true in subsequent examples and will not be further explained.

[0072] In one example, a receiving UE, for example UE4, has established a unicast connection with UE1. UE1 has configured a set of RSs for UE4 for beam maintenance, where the set of RSs includes S-SSB. If UE4 wants to provide feedback for S-SSB, UE4 determines a resource in the feedback channel resource set based on the first parameter to send PSFCH to notify UE1 of the beam status of S-SSB. In one example, the PSFCH resource used by UE4 is numbered (ID4) mod (R1), where ID4 is the first parameter determined by UE4. In one example, ID4 comes from a value configured by UE1. For example, when UE1 configures the RS for beam maintenance, it also configures the first parameter used by UE4 for S-SSB; or ID4 can be equal to (P ID +M ID4 ), where P ID is one or more physical identifiers indicated in the S-SSB, M ID4 The value configured by UE1, for example, when UE1 configures the RS for beam maintenance, it also configures the M used by UE4 for S-SSB. ID It can be seen that most of the time, ID4 and M IDIn reality, these parameters are equivalent and can be derived from each other through computation. They are collectively referred to as the first parameter used to determine PSFCH resources. Whether UE1 directly configures ID4 or configures M_ID4 to obtain the first parameter, this can be collectively referred to as configuring a corresponding first parameter for UE4. When UE4 establishes a connection with UE1 and obtains configuration information from UE1, the PSFCH resources it uses based on the first parameter are unique to UE4.

[0073] It can be seen that since the configuration information related to the first parameter is bound to the measurement RS configured for a specific purpose, Example 1 can be understood as UE1 distinguishing the PSFCH resources corresponding to measurements for different purposes of different UEs by configuring the first parameter or configuring various identification information.

[0074] In one example, a receiving UE, for example UE5, has established a unicast connection with UE1. UE1 has configured a set of RSs for UE5 for beam failure detection, where this set of RSs includes S-SSB. If UE5 wants to provide feedback for S-SSB, UE5 determines a resource in the feedback channel resource set based on the first parameter to send PSFCH to notify UE1 of the beam status of S-SSB. Similarly, the PSFCH resource used by UE5 is numbered (ID5) mod (R1), where ID5 is the first parameter determined by UE4 based on the configuration information of UE1. Similar to the above, ID5 can come directly from the UE1 configuration, or can be equal to (P ID +M ID5 ), where P ID is one or more physical identifiers indicated in the S-SSB, M ID5 Similarly, in one example, for a receiving UE, such as UE6, a set of RSs may be configured to determine candidate beams. If S-SSB is included, the same UE6 may be configured according to the configuration of UE1 (ID6 or M ID6 ) determines the corresponding first parameter and finally determines the PSFCH resource number used. The process is similar to the above process and will not be repeated here.

[0075] In addition, in one example, for the same UE, one RS can be configured for multiple purposes. For example, UE1 can also configure another set of RS for UE4 for BFD, which also includes S-SSB, and configure the relevant information to determine the corresponding first parameter, such as the configuration ID 4x or M ID4x, used to determine the corresponding PSFCH resources. Generally, in order to allow UE1 to distinguish the purpose for which UE4 sends feedback, for S-SSB, the first parameter determined by BM is different from the first parameter determined by BFD, so that the feedback resources corresponding to the two different purposes are also different. In addition, for different UEs, UE1 should configure different parameters for them in order to distinguish different UEs, such as configuring different IDs or M ID , to determine different first parameters, thereby determining different PSFCH resources. Furthermore, when UE1 configures parameters for determining the first parameter of the receiving UE, it should try to avoid conflicts with the default first parameter, i.e., try to avoid using the default feedback resource. That is, in Example 1, the first parameter can be used to distinguish different receiving UEs and different measurement purposes.

[0076] Example 1.1

[0077] For each S-SSB, it corresponds to a feedback channel resource set, which includes R1 PSFCH channel resources. In one example, UE1 can further divide the feedback channel resource set into different subsets, each of which corresponds to one or more purposes. Furthermore, UE1 can configure information to allow a receiving UE to determine its corresponding first parameter and PSFCH resource in a PSFCH subset.

[0078] For example, among R1 PSFCH resources, resource number 0 is used for IBP, resources numbered 1 to n are used for BM, resources numbered n+1 to m are used for BFD, and resources from m to R1-1 are used for CBD. It should be noted that this is only an example of a division. The specific division can also be discretely selected and assigned to specific purposes. There is no restriction on the specific subset division method. In addition, different purposes can also correspond to a subset. For example, the subsets corresponding to BFD and CBD can be the same subset. UE1 can notify the receiving UE established with it of these subset divisions and the correspondence between the subsets and measurement purposes through configuration information.

[0079] The method for determining the first parameter and feedback channel resources is described by taking the receiving end UE2 and UE3 performing CBD as an example. UE1 divides the feedback channel resource set corresponding to an S-SSB into several subsets. When UE1 configures UE2 and UE3 with reference signals for CBD, it also notifies UE2 and UE3 of the feedback channel resource subset corresponding to the reference signal. Assuming that an S-SSB is configured in both the reference signal used by UE2 for CBD and the CBD reference signal of UE3, a subset is divided from the PSFCH resource set corresponding to the S-SSB for CBD, and the subset contains R2 PSFCH resources. In one example, UE1 configures UE2 to determine the first parameter of the PSFCH resource in the subset, for example, configure Then the corresponding PSFCH resource number in the subset is The number of the PSFCH in the PSFCH resource set can be obtained by the number in the subset, which will not be described in detail later. Similarly, for UE3, UE1 configures the first parameter of UE3 to determine the PSFCH resource in the subset, for example, Then the corresponding PSFCH resource number in the subset is

[0080] A receiving UE can also correspond to measurements for multiple purposes and multiple subsets. UE1 can configure the first parameter corresponding to each subset to the receiving UE. For example, the reference signal used by UE2 for BFD also includes S-SSB, and UE1 allocates a subset of PSFCH resources to BFD. Assuming that the subset contains R3 PSFCH resources, UE1 needs to notify UE2 of the division of the subset. In one example, UE1 configures UE2 to determine the first parameter of the PSFCH resource in the subset corresponding to BFD, for example, Then the corresponding PSFCH resource number in the subset is

[0081] Example 1.2

[0082] For one S-SSB, it corresponds to a feedback channel resource set, which contains R1 PSFCH channel resources. In one instance, the network side, the base station, or other high-level entities (hereinafter referred to as the network side in this application) can further divide the feedback channel resource set into different subsets, and one subset can correspond to one or more purposes. For example, among the R1 PSFCH resources, the resource numbered 0 is used for the purpose of IBP, the resources numbered 1 to n are used for BM, the resources n+1 to m are used for BFD, and the resources from m to R1-1 are used for CBD. It should be noted that this is only an example of division, and the specific division can also discretely select some numbered divisions for specific purposes, and there is no restriction on the specific subset division method; in addition, different purposes can also correspond to a subset, for example, the subsets corresponding to BFD and CBD can be the same subset. The network can notify the UE of the division of these subsets and the correspondence between the subsets and the measurement purposes through configuration information.

[0083] Furthermore, UE1 can use configuration information to allow a receiving UE to determine its corresponding first parameter and PSFCH resource within a PSFCH subset. The specific details are similar to those in Example 1.1 and are not further described here. That is, the main difference between this example and Example 1.1 is that the division of the PSFCH resource subsets is configured by the network, while the process for the receiving UE to determine the corresponding first parameter and PSFCH resource within the subset is the same.

[0084] Example 1.3

[0085] One S-SSB may correspond to multiple feedback channel resource sets. As shown in Example 1, the network side may configure multiple PSFCH candidate resource sets. Different candidate PSFCH resource sets correspond to different purposes. As shown in Example 1, through the mapping relationship between S-SSB and PSFCH resources, one S-SSB may obtain its corresponding multiple PSFCH resource sets. For example, set 1 is a PSFCH resource set mapped from the candidate resource set for IBP, which contains R1 PSFCH resources. Similarly, set 2 containing R2 PSFCHs is used for BM, and set 3 containing R3 PSFCH resources is used for BFD, etc.

[0086] Furthermore, UE1 can configure a receiving UE to determine its corresponding first parameter and PSFCH resource within a PSFCH resource set through configuration information. The details are similar to those in Example 1.1 and are not further described here. That is, Examples 1.1, 1.2, and 1.3 are essentially similar solutions, in that one S-SSB corresponds to multiple sets or subsets, and the process of determining the corresponding first parameter and PSFCH resource within a subset or set is consistent.

[0087] Example 2

[0088] This embodiment is illustrated by taking a group of RSs consisting of multiple RSs as an example. For example, the UE may send multiple RSs on a basic time domain unit, such as sending multiple channel state information reference signals (CSI-RS) in one slot, and multiple RSs may correspond to multiple beam directions. Assume that a group of RSs sent by the UE in one slot may include at most N1 RSs. According to the method of embodiment 1, this group of RSs can be regarded as a whole, that is, when mapping PSFCH resources, this group of RSs is similar to an S-SSB in embodiment 1. In one instance, a group of RSs is mapped to a PSFCH resource set, and the resource set includes R1 PSFCH resources. It can be seen that embodiment 1 can actually be regarded as a special case of embodiment 2, that is, a group of RSs contains only one RS.

[0089] In one instance, similar to S-SSB, a group of RSs is associated with an indication information. For example, the indication information can be carried in the sidelink control information (Sidelink Control Information, SCI), the MAC control element (MAC CE), or the broadcast information physical sidelink broadcast channel (Physical Sidelink Broadcast CHannel, PSBCH). SCI will be used as an example to illustrate below.

[0090] In one example, the transmitting UE, for example UE1, sends a set of RSs, including N2 RSs, where N2 is less than or equal to N1. A set of RSs can be used for measurement of multiple UEs and multiple purposes. A set of RSs corresponds to a feedback channel resource set, which includes R1 PSFCH resources.

[0091] In embodiment 1, each receiving UE determines the PSFCH resource to be used from a set of RS feedback channel resources according to its corresponding first parameter. The first parameter can come from at least one of the following: an instruction or configuration of UE1, a configuration of the network or base station, or a predefined default value.

[0092] In one example, a receiving UE, for example UE2, receives an S-SSB and UE2 wants to establish a unicast connection with UE1. If UE2 wants to complete the initial beam pairing with UE1, UE2 can determine a resource in the feedback channel resource set according to the first parameter to send a PSFCH to notify UE1 of the beam status of one or more RSs in a group of RSs. In one example, if UE2 wants to provide feedback for RS numbered n in a group of RSs, the PSFCH resource used is numbered (ID 0-n )mod(R1), where (ID 0-m ) is the first parameter determined by UE2. In one example, (ID 0-n ) can be equal to a predefined default value or a configured value, or a calculation based on the default value, for example, the predefined value is the number n of the RS in a group of RSs; or (ID 0-n ) is equal to (P ID +M ID ), where P ID One or more physical identifiers indicated in the indication information corresponding to a group of RSs. For example, the SCI may carry the identifier corresponding to UE1 and sometimes may also carry the target receiving identifier, which is used to limit the receiver of a group of RSs. ID It can be equal to a predefined default value or a configured value, for example, it can be equal to the number n of RS in a group of RSs. 0-n Equal to (P ID +M ID +n), where P ID is one or more physical identifiers indicated in the indication information corresponding to a group of RSs, M ID It can be equal to a predefined default value or a configured value, for example, equal to 0, and n is the number n of the RS in a group of RSs. It can be seen that these methods are actually equivalent and can be converted into each other, and will not be listed later. Since UE2 has not yet established a connection with UE1, it cannot obtain configuration information from UE1. Similar to Example 1, from the perspective of UE1, if UE1 receives feedback from a PSFCH resource corresponding to an RS, it can only determine that there is UE feedback in the RS beam direction, but cannot determine which UE or how many UEs it comes from. At this time, the first parameter can be understood as a default parameter for each RS, and its corresponding feedback resource can also be understood as the default resource of the RS.

[0093] In one example, a receiving UE, for example UE4, has established a unicast connection with UE1. UE1 configures RS for UE4 for beam maintenance, wherein the configured RS includes one or more of a group of RSs sent by UE1. If UE4 wants to provide feedback for an RS numbered n in the group of RSs, UE4 determines a resource in the feedback channel resource set according to the first parameter to send PSFCH. In one example, the number of the PSFCH resource used by UE4 is (ID 4-n )mod(R1), where ID 4-n The first parameter determined for UE4. In one example, ID 4-n The value configured by UE1, for example, when UE1 configures the RS for beam maintenance, it also configures the first parameter used by UE4 for RS; or it can be ID 4-n Equal to (P ID +M ID4-n ), where P ID is one or more physical identifiers indicated in the control information of RS, M ID4-n The value from UE1 configuration; or ID 4-n Equal to (P ID +N1*M ID4 +n), M ID4 The value configured by UE1. It can be seen that the above examples are equivalent. In short, for one RS in a group of RSs, UE1 can configure the first parameter corresponding to the RS for UE4 through configuration information and determine the corresponding PSFCH resource. As in Example 1, for different UEs and different purposes, their corresponding PSFCH feedback resources can be determined by configuring different first parameters. That is, in Example 2, different receiving UEs, different measurement purposes, and different RSs in a group of RSs can be distinguished through the first parameter.

[0094] Example 2.1

[0095] Similar to Example 1.1, a set of RSs corresponds to a feedback channel resource set, and the set includes R1 PSFCH channel resources. In one instance, UE1 can further divide the feedback channel resource set into different subsets, and one subset can correspond to one or more measurement purposes. Furthermore, UE1 can allow a receiving UE to determine the first parameter and PSFCH resource corresponding to one of the RSs in a PSFCH subset through configuration information. UE1 can notify the receiving UE connected to it of the division of these subsets and the correspondence between the subsets and the measurement purposes through configuration information. Similarly, similar to Example 1.2, the division of the subsets and the correspondence with the measurement purposes can also be configured by the network, or similar to Example 1.3, a set of RSs corresponds to multiple feedback channel resource sets, and one set can correspond to one or more measurement purposes. That is, similarly, a set of RSs corresponds to multiple sets or subsets, and for each set or subset, the transmitting UE can further determine the corresponding PSFCH resource through the configured first parameter. Set-1 (set 1 or subset 1) corresponds to IBP, Set-2 (set 2 or subset 2) corresponds to BFD, and Set-3 (set 3 or subset 3) corresponds to CBD. Assume that Set-1, Set-2, and Set-3 each contain R1, R2, and R3 PSFCH resources.

[0096] The method for determining the first parameter and feedback channel resources is described by taking the receiving end UE2 and UE3 performing CBD as an example. UE1 sends a set of RSs. When this set of RSs is used for CBD, its PSFCH resources are Set-3, which contains R3 resources. An RS with a number or sequence number n in this set of RSs is configured in the reference signal used by UE2 for CBD and is also configured in the CBD reference signal of UE3. In one example, UE1 configures UE2 to determine the first parameter of the PSFCH resource in Set-3, for example, Then the corresponding PSFCH resource number in the subset is Similarly, for UE3, UE1 configures UE3 to determine the first parameter of the PSFCH resource in the subset, for example, Then the corresponding PSFCH resource number in the subset is Similar to Example 2, For example, it can be directly configured by UE1, or equivalently obtained by calculating other configured parameters, such as configuring M ID2-n , Or configure M ID2 , Or other operations are performed to obtain the first parameters, which are collectively referred to herein as the first parameters configured by UE1 for determining the corresponding PSFCH resources.

[0097] Example 3

[0098] This embodiment describes the PSFCH transmission conditions and content in various scenarios. The above embodiment describes how to determine the corresponding PSFCH resource when a receiving UE transmits PSFCH feedback, such as measurement results. This embodiment describes the conditions that must be met for a receiving UE to transmit PSFCH. Assuming UE1 is the UE transmitting RS, the transmission conditions may vary depending on the receiving UE's measurement purpose.

[0099] For example, if the receiving end UE2 performs IBP, if the Reference Signal Receiving Power (RSRP) of an RS is greater than or equal to the first threshold, UE2 can send a corresponding PSFCH to notify the UERS that sends the RS that the corresponding beam is the beam expected or selected by UE2. Or, relatively speaking, if the receiving energy of the RS is one of the largest N RSs received by UE2, then UE2 can send a corresponding PSFCH to notify the RS that the beam is the selected beam. A special case is that N is 1, that is, only the best beam is fed back. It can be seen from the above embodiments that the PSFCH resources used for IBP may be used by multiple UEs, so multiple UEs can send the same content on one PSFCH resource to avoid interference. For example, if multiple UEs send sequences on the PSFCH resource, the sequences they use are the same.

[0100] For example, if the receiving end UE2 performs BFD, if the RSRP of an RS is less than or equal to the second threshold or cannot be detected, UE2 can send a corresponding PSFCH to notify the UERS sending the RS that the beam corresponding to the RS has deteriorated or failed; in addition, optionally, if the received energy is greater than or equal to the third threshold, UE2 can also send a PSFCH to notify that the beam is still available. The third threshold can be the second threshold, or greater than or equal to the second threshold.

[0101] For example, if the receiving end UE2 performs CBD, if the RSRP of an RS is greater than or equal to the fourth threshold, UE2 can send the corresponding PSFCH to notify the UERS that sends the RS that the beam corresponding to the new candidate beam is a new candidate beam; in addition, optionally, if the received energy is less than or equal to the fifth threshold, UE2 can also send PSFCH to notify that the beam is not a new selected beam. The fifth threshold can be the fourth threshold, or less than or equal to the fourth threshold. In addition, for UE2 to detect the RS corresponding to the CBD, in one example, UE2 detects the RS corresponding to the CBD only after detecting the beam failure. In one example, beam failure can mean that for RSs used for BFD, UE2 determines that these RSs have all failed beams, or the number or proportion of failed RSs or beams reaches a certain level; in another example, UE2 can also periodically detect the RS of the CBD and send PSFCH according to the above process. The feedback at this time does not necessarily notify the new candidate beam. For example, it can only notify whether the beam of the RS exceeds the threshold. In addition, for UE1 sending the RS corresponding to CBD, UE1 can send it periodically, or start sending the RS corresponding to CBD only after UE1 detects a beam failure. Here, UE1 detects the beam failure because UE1 receives a beam failure indication from UE2, or UE1 determines the beam failure based on other feedback information from UE2 or based on the inability to receive feedback information from UE2.

[0102] For example, if the receiving end UE2 performs BM, if the RSRP of an RS is greater than or equal to the sixth threshold, UE2 can send a corresponding PSFCH to notify the UERS that sends the RS that the beam corresponding to the RS is greater than or equal to the threshold. Or, relatively speaking, if the received energy of the RS is one of the largest N RSs received by UE2, then UE2 can send a corresponding PSFCH to notify the RS that the beam is one of the best N beams. A special case is that N is 1, that is, only the best beam is fed back. In addition, optionally, if the received energy is less than or equal to the seventh threshold, or the RS cannot be detected, UE2 can also send feedback information to notify that the beam corresponding to the RS is less than or equal to the threshold. The seventh threshold can be considered the sixth threshold, or less than or equal to the sixth threshold.

[0103] In addition to measuring and reporting the reference signal based on the beam as in the above example, the UE may also perform measurements and feedback based on other purposes. The method for obtaining the corresponding first parameter and feedback channel resources can use the above method. The present invention does not limit the purpose of measuring the reference signal. For example, other measurement purposes may include but are not limited to measuring RS to obtain channel state information (CSI), to obtain positioning information, to obtain propagation delay information, to obtain the receiving end UE received energy, to obtain timing deviation, to obtain frequency deviation, to obtain phase deviation, and so on.

[0104] In the above example, PSFCH carries binary information such as yes / no, good / bad. In some examples, PSFCH can also carry received energy information, or received energy level and other information. Similarly, this application does not limit the content carried by PSFCH. When PSFCH carries other information, the method of the present invention can still be used to determine the first parameter and the resources used by PSFCH.

[0105] In addition, the UE may need to send multiple PSFCHs at the same time. If these PSFCHs exceed the number of transmissions supported by the UE or exceed the total power transmitted by the UE, the UE needs to give priority to sending PSFCHs with higher priorities while meeting the power and transmission number restrictions.

[0106] For the PSFCH corresponding to the above-mentioned beam measurement, its priority may be equal to the priority of its corresponding indication information, such as the priority corresponding to or indicated by the PSBCH or SCI.

[0107] Alternatively, the network side may predefine or configure a priority for the PSFCH corresponding to the beam measurement, or predefine or configure different priorities for the PSFCH corresponding to measurements for different purposes, for example, configuring one priority for the feedback corresponding to the CBD and another priority for the BM measurement feedback.

[0108] In one example, the priority of the PSFCH corresponding to beam measurement can always be lower than the priority of the PSFCH carrying Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK). That is, if there are PSFCHs carrying HARQ-ACK information, these PSFCHs should be sent first. Alternatively, the priority values ​​of the two can be directly compared, for example, the one with a higher priority value has a lower priority.
