[0001] The present application belongs to the field of communication technology, and specifically relates to a beam management method, device and terminal. Background Art

[0002] The 5G New Radio (NR) system can support higher data rates and lower latency. In order to ensure system performance, the relevant technology mainly obtains and maintains a set of optimal beams for uplink and downlink transmissions through beam management, thereby ensuring the precise alignment of the transmit / receive beams required for directional links. At present, the beam management process involved in the 5G NR system mainly involves beam scanning, beam measurement, beam selection, and beam reporting, and its implementation process is determined by the terminal and network-side equipment (i.e., base stations, etc.).

[0003] However, for the sidelink (SL) scenario, SL transmission is determined by the terminal, which makes the relevant beam management process proposed in the 5G NR system not applicable to the SL scenario.

It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0030] It is worth noting that Figure 1 The terminals 11 shown in the figure can communicate directly with each other, and the link for direct communication between the terminals can be called a side link (sidelink, SL, or translated as secondary link, side link, side link, etc.).

[0031] Based on this, the technical solution provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0032] like Figure 2 As shown, it is a flowchart of a beam management method 200 provided by an exemplary embodiment of the present application. The method 200 can be, but is not limited to, executed by a first terminal, and can be specifically executed by hardware and / or software installed in the first terminal. In this embodiment, the method 200 can at least include the following steps.

[0033] S210: The first terminal measures or demodulates a first reference signal to obtain a first result.

[0034] Among them, the first reference signal can be sent by the second terminal based on the SL between the second terminal and the first terminal to implement beam management, such as beam failure detection, beam failure recovery, beam switching, beam update, etc. Optionally, the first reference signal can be but is not limited to a radio link monitoring (Radio Link Monitoring, RLM) reference signal (Reference Signal, RS), a beam failure detection (Beam Failure Detection, BFD) RS, a signal state information reference signal (Channel State Information-Reference Signal, CSI-RS), a synchronization signal block (Synchronization Signal and PBCH block, SSB), etc.

[0035] Based on this, in one implementation, the first result may be the measured beam quality of the receiving beam, the beam identification, whether the wireless link fails, etc., which is not limited here.

[0036] S220: Send a first transmission to a second terminal according to the first result.

[0037] Wherein, the first transmission is used for beam management. In one implementation, when implementing the beam management, the information carried in the first transmission may be different according to the type of the beam management, such as the first transmission may carry a beam failure recovery request (Beam Failure Recovery Request, BFRQ), beam switching information, channel state information (Channel State Information, CSI) reporting information, UE collaboration information (or UE recommendation information), data information, etc., which are not limited here.

[0038] Of course, in this embodiment, the first transmission can be SL physical random access channel (Physical Random Access Channel, PRACH), physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH), physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH), sidelink control information (Sidelink Control Information, SCI), medium access control element (Medium Access Control Control Element, MAC CE), etc., without limitation here.

[0039] Correspondingly, after receiving the first transmission, the second terminal can perform beam management according to the first transmission, such as beam switching, beam updating, beam failure recovery, etc., to ensure the beam quality in the SL scenario.

[0040] In this embodiment, in the SL, the first terminal sends a first transmission for beam management to the second terminal based on the measurement or demodulation result of the first reference signal, thereby enabling beam management on the SL to ensure beam quality.

[0041] like Figure 3 As shown, it is a flowchart of a beam management method 300 provided by an exemplary embodiment of the present application. The method 300 can be, but is not limited to, executed by a first terminal, and can be specifically executed by hardware and / or software installed in the first terminal. In this embodiment, the method 300 can at least include the following steps.

[0042] S310: A first terminal measures or demodulates a first reference signal to obtain a first result.

[0043] S320: Send a first transmission to the second terminal according to the first result.

[0044] Wherein, the first transmission is used for beam management.

[0045] It can be understood that the implementation process of S310-320 can refer to the relevant description in the aforementioned method embodiment 200, and will not be repeated here to avoid repetition.

[0046] S330: Receive a first response sent by the second terminal.

[0047] The first response corresponds to the first transmission, that is, the first response may be sent by the second terminal according to the first transmission.

[0048] In this embodiment, in order to ensure that the first terminal can correctly receive the first response, in one implementation, at least one of the following (11)-(12) may be satisfied between the first transmission and the first response.

[0049] (11) There is a correspondence between the time domain resources used for sending the first transmission and the time domain resources used for receiving the first response.

[0050] As an implementation method, the time domain resources used for sending the first transmission may be the first time unit in which the first transmission is located, or the first time window in which the first transmission is located, such as the time unit in which the first transmission is located (such as a time slot or symbol), or the time unit (slot or symbol) in which the first transmission starts or ends.

[0051] As an implementation method, the time domain resources used for receiving the first response may be a second time window or a second time unit in which the first response is received, and the first response may be received within at least one of a time not earlier than the first time upper limit and not later than the first time lower limit.

[0052] For example, after the first terminal sends the first transmission at time N1, it listens to the first response within the time window of N1+K1 to N1+K2, or listens to the first response at a time no earlier than N1+t1, or listens to the first response at a time no later than N1+t2. Thus, by limiting or constraining the timeline between the first transmission and the first response, the first terminal can correctly receive the first response.

[0053] Correspondingly, for the second terminal, after receiving the first transmission, if the second terminal receives the first transmission at time N2, then the first response can be sent within the time window of N2+K1 to N2+K2, or the first response can be sent no earlier than N2+t1, or the first response can be sent no later than N+t2. Thus, by limiting or constraining the timeline between the first transmission received by the second terminal and the first response sent, the first terminal can correctly receive the first response. Optionally, the correspondence between the time domain resources and the time domain resources can be determined by protocol pre-definition, network or terminal configuration, negotiation between the first terminal and the second terminal, etc.

[0054] As an implementation manner, at least one of the second time window, the second time unit, the first time upper limit, and the first time lower limit may be predefined by the protocol, configured or indicated by the network, configured or indicated by the first terminal, or negotiated between the first terminal and the second terminal, and is not limited here.

[0055] In addition, the resources selected by the second terminal when sending the first response may give priority to resources within the time domain resources to ensure that the first terminal can correctly receive the first response.

[0056] (12) There is a correspondence between the transmission beam used for the first transmission transmission and the reception beam used for the first response reception.

[0057] Among them, there is a corresponding relationship between the transmission beam used for the first transmission and the reception beam used for the first response reception, which may include but is not limited to at least one of the following (a)-(b).

[0058] (a) The transmit beam used for sending the first transmission is the same as the receive beam used for receiving the first response, that is, the beam used by the first terminal to receive the first response is equivalent to the beam used to send the first transmission.

[0059] (b) The receive beam used for the first response reception at least includes (or at least covers) the transmit beam used for the first transmission transmission.

[0060] Correspondingly, for the second terminal, the transmitting beam used for sending the first response and the receiving beam used for receiving the first transmission also have a corresponding relationship, such as the transmitting beam used for sending the first response is the same as the receiving beam used for receiving the first transmission, or the transmitting beam used for sending the first response at least includes the receiving beam used for receiving the first transmission.

[0061] Among them, the correspondence between the beam corresponding to the first transmission and the beam of the first response is defined through the aforementioned implementation method, which can ensure that the first terminal correctly receives the response to the first transmission and achieve the purpose of beam management.

[0062] It is worth noting that, for the aforementioned first response, in this embodiment, depending on the type of beam management corresponding to the first transmission, the first response can be used for at least one of the following (21)-(23).

[0063] (21) Indicating beam information or time domain resource information between the second terminal and the first terminal, so that the first terminal performs beam management based on the beam information or time domain resource information.

[0064] (22) The first terminal updates the beam information where the beam failure occurs to implement beam management.

[0065] (23) Confirmation of the first transmission by the second terminal.

[0066] In this embodiment, by limiting or constraining the time domain resources and the transceiver beams between the first transmission and the first response, it can effectively ensure that the first terminal correctly receives the response to the first transmission, thereby achieving the purpose of beam management.

[0067] like Figure 4 As shown, it is a flowchart of a beam management method 400 provided by an exemplary embodiment of the present application. The method 400 can be, but is not limited to, executed by a first terminal, and can be specifically executed by hardware and / or software installed in the first terminal. In this embodiment, the method 400 can at least include the following steps.

[0068] S410: A first terminal measures or demodulates a first reference signal to obtain a first result.

[0069] S420: Send a first transmission to a second terminal according to the first result.

[0070] Wherein, the first transmission is used for beam management.

[0071] It can be understood that in addition to referring to the relevant descriptions in the aforementioned method embodiments 200-300, the implementation process of S410-S420, as a possible implementation method, depending on the type of beam management, the first transmission may carry or indicate at least one of the following (31)-(34).

[0072] (31) A beam failure recovery request, used to request the second terminal to perform beam failure recovery.

[0073] (32) Beam switching information, used by the first terminal to trigger the second terminal to perform beam switching. In this embodiment, the beam switching information may also be referred to as a beam switching indication, a beam switching request, etc.

[0074] In this case, as a possible implementation method, the beam switching information may include but is not limited to at least one of the following (321)-(323).

[0075] (321) Information of a first beam or a beam pair, where the first beam or the beam pair is a beam or a beam pair used after beam switching. In other words, the first beam or the beam pair is a new beam or a beam pair.

[0076] Optionally, the information of the first beam or beam pair includes but is not limited to a beam identifier (ID), a beam pair identifier, a transmission configuration indicator (TCI), a resource identifier (resource ID), etc. The beam identifier or the beam pair identifier is used to instruct the second terminal to switch to the corresponding first beam or beam pair, and the beam pair identifier is a logical identifier (Logic ID). It can be understood that at least one beam or beam pair can be maintained (or maintained) between the first terminal and the second terminal.

[0077] The TCI is used to instruct the second terminal to switch to the first beam or beam pair.

[0078] The resource identifier is used to instruct the second terminal to switch to the resource where the first beam or beam pair is located.

[0079] (322) Time domain resource information (such as a time domain resource identifier) ​​associated with the first beam or beam pair, so that the second terminal can determine a new beam to switch to based on the time domain resource information.

[0080] For example, the time domain resource information of the first beam or beam-associated beam may be the time domain resources associated with the beam or beam pair (i.e., the second beam or beam pair) that is replaced (or before switching) (i.e., the beam switching information only indicates the switched beam, and the time domain resources of the replaced beam are still valid).

[0081] Alternatively, the time domain resource information associated with the first beam or beam pair may also be time domain resource information specially configured for the first beam or beam pair.

[0082] (323) Information about a second beam or a beam pair, where the second beam or a beam pair is the beam or a beam pair used before the beam switching, that is, the beam or a beam pair to be replaced.

[0083] For example, assuming that multiple beam pairs are maintained between the first terminal and the second terminal, where the second terminal transmits using beam #1, and the first terminal discovers that beam #2 of the second terminal has failed based on measurement or decoding of the first reference signal, then the first terminal can instruct a new beam to replace beam #2, while the second terminal can still transmit using beam #1.

[0084] It is worth noting that in this embodiment, when performing beam switching, the first terminal indicates the beam switching information to the second terminal to trigger the second terminal to perform beam switching according to the beam switching information, thereby ensuring the reliability of the beam switching and ensuring communication performance.

[0085] In this case, as a possible implementation, when the first terminal triggers beam switching through the beam switching information, it can send the first transmission to the second terminal based on the first result and based on a specific resource or a specific beam, wherein the specific beam or the specific resource is used to implicitly indicate beam switching. That is, when the first transmission is sent based on a specific beam or a specific resource, it is equivalent to implicitly carrying the beam switching information in the first transmission to trigger beam switching.

[0086] Alternatively, the first terminal may also send the first transmission to the second terminal according to the first result, wherein the first transmission carries the beam switching information. That is, the first transmission explicitly carries the beam switching information to trigger the beam switching.

[0087] Therefore, by providing the aforementioned different beam switching triggering methods, the flexibility of beam switching can be achieved.

[0088] Correspondingly, for the second terminal, when the first terminal sends a first transmission based on a specific beam or specific resources, the second terminal determines that beam switching is required, and switches to the specific first beam to send a first response and subsequent other transmissions.

[0089] It can be understood that the aforementioned specific beam and specific first beam may be a default beam, and the default beam may be predefined by the protocol, configured / indicated by the network or terminal (such as the first terminal or the second terminal), or determined by negotiation between the first terminal and the second terminal. For example, the default beam may be the wide beam used for initial access, etc.

[0090] The specific resources are predefined by the protocol, configured / indicated by the network or the terminal (such as the first terminal or the second terminal), or determined by negotiation between the first terminal and the second terminal. For example, the specific resources are specific PSFCH resources or specific sequences.

[0091] In addition, there may be a correspondence between a specific first beam in which the second terminal sends the first response and a beam in which the first transmission is received.

[0092] (33) CSI reporting information, used by the second terminal to perform beam update, such as updating the reference signal received power (RSRP) measurement information of the beam, transmitting beam information, etc.

[0093] The CSI reporting information may include but is not limited to at least one of the following (331)-(334).

[0094] (331) CSI report, wherein the CSI report may carry the beam identifier, CSI-RS Resource Indicator (CRI), RSRP, Acknowledgement (ACK), etc. of a new beam (such as the aforementioned first beam or beam pair, candidate beam), and may also carry the beam identifier, CRI, RSRP, ACK, etc. of a current beam (i.e., a beam receiving a first reference signal, etc.), so that the second terminal can perform a beam update according to the CSI report, such as selecting a new transmit beam.

[0095] (332) beam status information or beam change information; for example, the beam status information or beam change information may be beam status information or beam change information of multiple beams or beam pairs maintained between the first terminal and the second terminal, such as RSRP of the multiple beams or beam pairs, whether the multiple beams or beam pairs are available, etc.

[0096] (333) The resource unit (such as a time slot, etc.) where the beam or reference signal corresponding to the CSI report is located.

[0097] (334) The time domain offset between the beam or reference signal corresponding to the CSI report and the first transmission.

[0098] In addition, the first terminal may also trigger CSI reporting and send a CSI report of the new beam to the second terminal so that the second terminal updates the transmitting beam according to the CSI report; or the first terminal may send a measured CSI report to the second terminal so that the second terminal updates the RSRP information of the beam according to the CSI report and selects a new transmitting beam to achieve beam update.

[0099] In one implementation, if the first transmission carries or indicates the CSI reporting information, then the sending time of the CSI reporting information satisfies at least one of the following (a)-(b).

[0100] (a) The CSI reporting information is sent within a first number of time units after the first reference signal is received. That is, the first terminal sends the CSI reporting information within a first number of time units after receiving the first reference signal.

[0101] Optionally, the first number and the subsequent second number may be predefined by a protocol, configured / indicated by a network or terminal, determined by negotiation between the first terminal and the second terminal, etc., and are not limited here.

[0102] (b) When the first reference signal is a periodic signal, the sending time of the CSI reporting information is before the receiving time of the first reference signal of the next period.

[0103] For example, after receiving the first reference signal and before receiving the first reference signal of the next period, the first terminal sends the CSI reporting information to the second terminal.

[0104] (c) In the case where there are multiple first reference signals, the sending time of the CSI reporting information is within a first number of time units after the receiving time of a second reference signal, wherein the second reference signal is one of the multiple first reference signals.

[0105] For example, if the first terminal measures a group of first reference signals (i.e., multiple first reference signals), the first terminal can send CSI reporting information to the second terminal within a first number of time units after the Nth (e.g., the last) first reference signal in a group of first reference signals.

[0106] In addition, in another implementation, if the first terminal needs to send the CSI reporting information to the second terminal multiple times, then the sending time of each CSI reporting information also satisfies any one of the following (d)-(g).

[0107] (d) The difference between the sending time of the first CSI reporting information and the sending time of the second CSI reporting information, which are adjacent in sending time, is not less than the second number of time units.

[0108] Among them, the first CSI reporting information and the second CSI reporting information mentioned in this embodiment belong to the CSI reporting information sent multiple times.

[0109] (e) When the reporting process of the first CSI reporting information is triggered by the first terminal and the reporting process of the second CSI reporting information is triggered by the second terminal, within a second number of time units after the first CSI reporting information, the second CSI reporting information is allowed to be sent, or the second CSI reporting information is not allowed to be sent.

[0110] Exemplarily, for the situation where the sending of the second CSI reporting information is allowed, if the content contained in the first CSI reporting information is the same as the dimension of the second CSI reporting, such as both reporting the RSRP of the reference signal, then the same signaling can be used to send the first CSI reporting information and the second CSI reporting information together, thereby saving signaling overhead and improving reporting efficiency.

[0111] Alternatively, if the first CSI reporting information and the second CSI reporting information are obtained according to the same reference signal, the first CSI reporting information and the second CSI reporting information may be sent together using the same signaling, thereby saving signaling overhead and improving reporting efficiency.

[0112] Alternatively, if the first CSI reporting information and the second CSI reporting information are obtained according to different reference signals, the first CSI reporting information and the second CSI reporting information are sent using different signaling, that is, the first CSI reporting information and the second CSI reporting information need to be sent separately, thereby ensuring the accuracy of the CSI reporting information.

[0113] (f) When both the reporting process of the first CSI reporting information and the reporting process of the second CSI reporting information are triggered by the first terminal, sending the second CSI reporting information is not allowed within a second number of time units after the first CSI reporting information, thereby avoiding frequent triggering of reporting by the first terminal.

[0114] (g) when the reporting process of the first CSI reporting information is triggered by the second terminal and the reporting process of the second CSI reporting information is triggered by the first terminal, within a second number of time units after the first CSI reporting information, sending the second CSI reporting information or not allowing the sending of the second CSI reporting information.

[0115] Among them, similar to the aforementioned (e), for the situation where the second CSI reporting information is allowed to be sent, if the content contained in the first CSI reporting information is the same as the dimension of the second CSI reporting, such as both reporting the RSRP of the reference signal, then the same signaling can be used to send the first CSI reporting information and the second CSI reporting information together, thereby saving signaling overhead and improving reporting efficiency.

[0116] Alternatively, if the first CSI reporting information and the second CSI reporting information are obtained according to the same reference signal, the first CSI reporting information and the second CSI reporting information may be sent together using the same signaling, thereby saving signaling overhead and improving reporting efficiency.

[0117] Alternatively, if the first CSI reporting information and the second CSI reporting information are obtained according to different reference signals, the first CSI reporting information and the second CSI reporting information are sent using different signaling, that is, the first CSI reporting information and the second CSI reporting information need to be sent separately, thereby ensuring the accuracy of the CSI reporting information.

[0118] In addition, when the CSI reporting information includes multiple CSI reports corresponding to the first reference signals, the position or order of each CSI report in the CSI reporting information is determined according to the index size (such as ascending or descending order) of each first reference signal, or the index size (such as ascending or descending order) of the resource unit where each first reference signal is located, so as to ensure that the second terminal can accurately receive each CSI report.

[0119] (34) First UE cooperation information, used to assist the second terminal in beam management.

[0120] Among them, the first UE collaboration information includes at least one item among the following (341)-(347).

[0121] (341) The first terminal recommends resource information (such as time domain resources, etc.) for the first response or the first communication process; wherein the first communication process includes a beam failure recovery process or a data transmission process, etc.

[0122] (342) The first terminal does not recommend resource information for the first response or the first communication process.

[0123] Exemplarily, for the aforementioned (341)-(342), when the second terminal receives resource information recommended or not recommended by the first terminal, if it needs to determine the resources corresponding to the first response or the first communication process, then the second terminal may give priority to the resource information recommended by the first terminal, or give priority to excluding the resource information not recommended by the first terminal.

[0124] (343) The first terminal recommends offset information of time domain resources between the time domain resources used for the first response and the first reference signal.

[0125] (344) The first terminal does not recommend offset information of time domain resources between the time domain resources used for the first response and the first reference signal.

[0126] Exemplarily, for the aforementioned (343)-(344), when the second terminal receives the offset information of the time domain resources recommended or not recommended by the first terminal, if it needs to determine the resources of the first response, then the second terminal may give priority to the resources on the recommended time domain offset, or give priority to excluding the resources on the not recommended time domain offset.

[0127] (345) The first terminal recommends beam information for the first response or the first communication process.

[0128] (346) The first terminal does not recommend beam information for the first response or the first communication process.

[0129] Exemplarily, for the aforementioned (345)-(346), when the second terminal receives beam information recommended or not recommended by the first terminal, the second terminal gives priority to using the recommended beam information to send the first response or perform the first communication process, or gives priority to excluding the not recommended beam information.

[0130] (347) Resource information associated with a third beam, wherein the third beam belongs to a beam or a beam pair maintained between the first terminal and the second terminal.

[0131] Exemplarily, assuming that multiple pairs of beams are maintained between the first terminal and the second terminal, and the first terminal indicates resource #1 associated with beam #1 and resource #1 associated with beam #2, then the second terminal can use beam #1 to send on resource #1 and use beam #2 to send on resource #2.

[0132] In one implementation, before sending the first transmission, the first terminal may also receive second UE cooperation information sent by the second terminal to assist or assist the beam management between the first terminal and the second terminal. For example, the first terminal may determine the first UE cooperation information and the resources corresponding to the first transmission based on the second UE cooperation information.

[0133] Optionally, the second UE collaboration information includes at least one item of the following (51)-(57).

[0134] (51) The second terminal recommends resource information for the first transmission or the second communication process; wherein the second communication process includes a beam failure recovery process.

[0135] (52) the second terminal does not recommend resource information for the first transmission or the second communication process;

[0136] Exemplarily, for the aforementioned (51)-(52), when the first terminal receives resource information recommended or not recommended by the second terminal, it may give priority to the recommended resource information for the first transmission or second communication process, or give priority to excluding not recommended resources.

[0137] (53) The second terminal recommends offset information of time domain resources between the time domain resources used for the first transmission and the first reference signal.

[0138] (54) The second terminal does not recommend offset information of time domain resources between the time domain resources used for the first transmission and the first reference signal.

[0139] Exemplarily, for the aforementioned (53)-(54), when the first terminal receives the offset information of the time domain resources recommended or not recommended by the second terminal, if it is necessary to determine the time domain resources of the first transmission, then the first terminal may give priority to the resources on the recommended time domain offset, or give priority to excluding the resources on the not recommended time domain offset.

[0140] (55) The second terminal recommends beam information for the first transmission or second communication process.

[0141] (56) The second terminal does not recommend beam information for the first transmission or the second communication process.

[0142] Exemplarily, for the aforementioned (55)-(56), when the first terminal receives beam information recommended or not recommended by the second terminal, the second terminal preferentially uses the recommended beam information for the first transmission or second communication process, or preferentially excludes the not recommended beam information.

[0143] (57) Resource information associated with a fourth beam, where the fourth beam belongs to a beam or a beam pair maintained between the first terminal and the second terminal.

[0144] Exemplarily, assuming that multiple pairs of beams are maintained between the first terminal and the second terminal, and the second terminal indicates resource #1 associated with beam #1 and resource #1 associated with beam #2, then the first terminal can use beam #1 to send on resource #1 and use beam #2 to send on resource #2.

[0145] It is worth noting that for the aforementioned beam failure recovery request, beam switching information, CSI reporting information, and first collaborative information, the first terminal can use one or more of the beam information used to indicate beam management (such as beam switching, beam updating, and beam failure recovery) so that the second terminal can perform beam management according to the indicated beam information; alternatively, the second terminal can autonomously determine the beam information used for beam management (such as beam switching, beam updating, and beam failure recovery) based on the beam failure recovery request, beam switching information, CSI reporting information, and first collaborative information sent by the first terminal, thereby implementing beam management, thereby ensuring the flexibility of beam management.

[0146] In one implementation, in order to avoid frequent reporting of the first transmission, in this embodiment, when the first terminal sends the first transmission to the second terminal according to the first result, the first terminal sends the first transmission to the second terminal according to the first result when the following first condition is met. The first condition includes at least one of the following (61)-(63).

[0147] (61) The beam quality within a predetermined time period is lower than a first threshold value.

[0148] (62) The transmission beam of the second terminal expected by the first terminal is different from the transmission beam used by the second terminal.

[0149] For example, if the transmit beam of the second terminal corresponding to the receive beam expected by the first terminal is different from the current transmit beam of the second terminal, the first terminal triggers reporting of the first transmission.

[0150] (63) The number of times that the measurement result of the first reference signal is (continuously) lower than the second threshold value reaches a predetermined value.

[0151] Correspondingly, when the second terminal receives the first transmission sent by the first terminal and performs beam management according to the first transmission, its implementation method may include at least one of the following (71)-(74).

[0152] (71) Perform beam switching according to the first transmission.

[0153] For example, the second terminal can perform beam recovery or beam switching according to the BFRQ, beam switching information, CSI reporting information, etc. carried in the first transmission, and there is no limitation here.

[0154] (72) Sending a third reference signal to the first terminal according to the first transmission, and upon receiving beam feedback information corresponding to the third reference signal, performing beam recovery or beam switching according to the beam feedback information.

[0155] For example, the second terminal triggers the sending of the third reference signal according to the received first transmission, and performs beam recovery or beam switching after receiving the beam feedback information sent by the first terminal, thereby further ensuring the reliability of the beam management result.

[0156] (73) Stop a predetermined communication behavior according to the first transmission until the beam is restored, wherein the predetermined communication behavior is used for terminal energy saving.

[0157] Optionally, the stopping of the predetermined communication behavior includes but is not limited to stopping partial sensing and performing full sensing, turning off discontinuous reception (DRX), etc.

[0158] (74) During a beam failure recovery process or a beam switching process according to the first transmission, UE cooperation information obtained based on a fifth beam is ignored, where the fifth beam includes a beam in which a beam failure occurs or a beam before beam switching is performed.

[0159] In this embodiment, beam management between the first terminal and the second terminal can be achieved by sending the first transmission (such as BFRQ, beam switching information, CSI reporting information, UE cooperation information, etc.).

[0160] In particular, in the present application, by triggering beam switching, beam updating, etc., the beam failure recovery process can be quickly implemented, effectively reducing the signaling interaction between the first terminal and the second terminal.

[0161] Based on the description of the aforementioned method embodiments 200-400, the beam management method provided in the present application is exemplarily introduced in combination with Example 1 and Example 2, as follows.

[0162] Example 1

[0163] (1) When the first terminal determines that the beam failure occurs by decoding or measuring the first reference signal (such as BFD RS), the second terminal is informed of the beam failure through BFRQ (i.e., the first transmission) and a new candidate beam is indicated.

[0164] (2) After receiving the BFRQ, the second terminal replies to the first terminal with a beam failure recovery response (BFRR) (i.e., a first response) to confirm the new beam. The BFRR may include beam indication information for indicating new beam information and / or time domain resource information, so that the first terminal may subsequently use the new beam indicated by the BFRR for communication.

[0165] Among them, after sending the BFRQ, the first terminal uses a receiving beam covering the new beam to monitor the BFRR within a time window, and when the second terminal selects resources to send the BFRQ, it gives priority to the resources within the time window to send the BFRR. For example, the second terminal determines that the resource selection window is within the time window; or the second terminal at least ensures that some candidate resources are within the time window; or the second terminal gives priority to the candidate resources within the time window, thereby ensuring that the first terminal can correctly receive the first BFRR, and then ensure the smooth recovery of the beam failure.

[0166] Example 2

[0167] (1) When the first terminal determines that the current beam link quality is poor and beam failure occurs by decoding or measuring the first reference signal (such as RLM RS), beam switching is triggered to instruct the second terminal to switch to other links with better beam quality. The beam switching indication (i.e., the beam switching information carried or indicated in the first transmission) can be sent through the first transmission such as SL PRACH, PSFCH, SCI, MAC CE, etc.

[0168] If the information of the beam / measurement reference signal ID is maintained between the second terminal and the first terminal, the beam switching indication may indicate switching to a new beam / measurement reference signal ID.

[0169] If multiple beam pairs are maintained between the second terminal and the first terminal, and different beam pairs are represented by different logical IDs, the beam switching indication may indicate the logical ID of the new beam pair switched to. Based on this, the first terminal may also indicate the resource identifier of the measured new transmission beam in the beam switching indication, so that the second terminal determines the new beam to switch to based on the resource identifier.

[0170] In addition, the first terminal may also trigger CSI reporting and send a CSI report of the new beam to the second terminal so that the second terminal updates the transmitting beam according to the CSI report; or the first terminal may send a measured CSI report to the second terminal so that the second terminal updates the RSRP information of the beam according to the CSI report and selects a new transmitting beam to achieve beam update.
