[0053] This disclosure provides an information processing method, apparatus, and storage medium.

[0054] In a first aspect, embodiments of this disclosure provide an information processing method, executed by a first terminal, the method comprising:

[0055] Determine that the first beam used for communication with the second terminal has failed, and determine the second beam;

[0056] The first information is sent to the second terminal via the second beam, and the first information is used to indicate that the first terminal has experienced beam failure.

[0057] In the above embodiments, the first terminal determines a second beam for transmitting the first information, so that the first terminal can reliably transmit the first information to the second terminal, ensuring reliable communication between the first terminal and the second terminal in the event of beam failure.

[0058] In conjunction with some embodiments of the first aspect, in some embodiments, the second beam is not any one or more of the following:

[0059] A beam that uses the same transmission configuration indication TCI configuration as the first beam; a beam that is quasi-co-located with the TCI configuration used by the first beam; a beam that is quasi-co-located with the first beam; a beam that has spatial co-location with the first beam.

[0060] In the above embodiments, not using these beams can avoid the problem that the second beam is similar to or close to the failed first beam, which would prevent the first information from being reliably sent to the second terminal.

[0061] In conjunction with some embodiments of the first aspect, in some embodiments, the second beam is any one or more of the following:

[0062] A beam that uses the same TCI configuration as the candidate beam; a beam that is quasi-co-located with the TCI configuration used by the candidate beam; a beam that is quasi-co-located with the candidate beam; a beam that is spatially consistent with the candidate beam.

[0063] In the above embodiments, the second beam can be determined as a candidate beam that is close to or similar to the first beam that can be used to send information from the first terminal to the second terminal, so that the first terminal can reliably send the first information to the second terminal.

[0064] In conjunction with some embodiments of the first aspect, in some embodiments, the method includes, before determining the second beam:

[0065] Send a second message to the network device, the second message including any one or more of the following:

[0066] The beam identifier of the first beam; the beam identifier of the candidate beam; the beam identifier of the beam using the same TCI configuration as the first beam; the beam identifier of the beam quasi-co-located with the TCI configuration used by the first beam; the beam identifier of the beam quasi-co-located with the first beam; the beam identifier of the beam spatially consistent with the first beam; the beam identifier of the beam using the same TCI configuration as the candidate beam; the beam identifier of the beam quasi-co-located with the TCI configuration used by the candidate beam; the beam identifier of the beam quasi-co-located with the candidate beam; the beam identifier of the beam spatially consistent with the candidate beam.

[0067] In the above embodiments, the network device can accurately obtain the beam-related information of the first terminal, thereby enabling more accurate instructions so that the first terminal can reliably send the first information to the second terminal.

[0068] In conjunction with some embodiments of the first aspect, in some embodiments, determining the second beam includes:

[0069] Receive third information sent by the network device;

[0070] The second beam is determined based on the third information.

[0071] In the above embodiments, the first terminal can receive third information sent by the network device and determine the second beam based on the third information, and then send the first information based on the beam indicated by the network, which can effectively ensure that the first terminal reliably sends the first information to the second terminal.

[0072] In conjunction with some embodiments of the first aspect, in some embodiments, the first information includes any one or more of the following:

[0073] The beam identifier of the first beam; the beam identifier of the candidate beam.

[0074] In the above embodiments, by carrying the beam identifier of the beam in the first information, the second terminal can be effectively informed of the failed beam and the candidate beam, thereby enabling the second terminal to select the third beam based on the first information, so that the second terminal can reliably send information to the first terminal based on the third beam to achieve beam recovery.

[0075] In conjunction with some embodiments of the first aspect, in some embodiments, the candidate beam is one or more beams whose measurement results satisfy a preset threshold condition; or, the candidate beam is the beam with the best measurement results.

[0076] In the above embodiments, candidate beams that can be used to send information from the first terminal to the second terminal can be effectively determined, and then the first information can be reliably sent to the second terminal based on the candidate beams to ensure reliable communication between the first terminal and the second terminal in the event of beam failure.

[0077] In conjunction with some embodiments of the first aspect, in some embodiments, the method includes:

[0078] The fourth information is received, which is sent by the second terminal through the third beam after receiving the first information.

[0079] In the above embodiments, the first terminal can receive the fourth information sent through the third beam after beam failure, effectively ensuring reliable communication between the first terminal and the second terminal and realizing beam recovery after beam failure.

[0080] In conjunction with some embodiments of the first aspect, in some embodiments, the third beam is any one or more of the following:

[0081] Candidate beam; beam using the same TCI configuration as the second beam; beam quasi-co-located with the TCI configuration used by the second beam; beam quasi-co-located with the second beam; beam having spatial co-location with the second beam.

[0082] In the above embodiments, using a candidate beam or a beam similar to or close to the second beam can effectively ensure that the second terminal can reliably send the fourth information to the first terminal, thus ensuring reliable communication between the first terminal and the second terminal.

[0083] In conjunction with some embodiments of the first aspect, in some embodiments, the third beam is not any one or more of the following:

[0084] The first beam; a beam using the same TCI configuration as the first beam; a beam quasi-co-located with the TCI configuration used by the first beam; a beam quasi-co-located with the first beam; a beam having spatial co-location with the first beam.

[0085] In the above embodiments, since the first beam is a beam that has already failed, not using the above beam as the third beam can effectively avoid the problem that the third beam is close to or similar to the first beam, which would cause the fourth information to be unreliably sent to the first terminal, thus ensuring that the second terminal can effectively send the fourth information to the first terminal.

[0086] In conjunction with some embodiments of the first aspect, in some embodiments, during the first timer's operating time, the third beam is not any one or more of the following:

[0087] The first beam; a beam using the same TCI configuration as the first beam; a beam quasi-co-located with the TCI configuration used by the first beam; a beam quasi-co-located with the first beam; a beam having spatial co-location with the first beam.

[0088] In the above embodiments, since a failed beam may recover after a period of time, by setting a timer, the beam will not be used as a third beam only during the time period corresponding to the timer. After a certain period of time, a beam that is close to the failed beam can be used as a third beam.

[0089] In conjunction with some embodiments of the first aspect, in some embodiments, the first information is also used to instruct the second terminal to start the first timer.

[0090] In the above embodiments, by instructing the second terminal to start the first timer through the first information, the second terminal can trigger the timer immediately after receiving the first information, thus ensuring the immediacy of the timer start-up.

[0091] In conjunction with some embodiments of the first aspect, in some embodiments, the first timer is sent to the second terminal by the first terminal or network device, or the first timer is obtained by the second terminal from a pre-configuration.

[0092] In the above embodiments, the first timer can be sent to the second terminal through the first terminal or network device without the second terminal needing to configure the timer, which effectively saves the resource consumption of the second terminal. The timer can also be obtained by the second terminal from the pre-configuration, which makes the timer more suitable for the capabilities of the second terminal.

[0093] Secondly, embodiments of this disclosure provide an information processing method, executed by a second terminal, the method comprising:

[0094] The system receives first information, which is transmitted via a second beam. The first information is used to indicate that the first terminal has experienced a beam failure.

[0112] In conjunction with some embodiments of the second aspect, in some embodiments, the first information is also used to instruct the second terminal to start the first timer.

[0113] In conjunction with some embodiments of the second aspect, in some embodiments, the first timer is sent to the second terminal by the first terminal or network device, or the first timer is obtained by the second terminal from a pre-configuration.

[0114] In conjunction with some embodiments of the second aspect, in some embodiments, the method includes, before determining the third beam:

[0115] Send a fifth message to the network device, the fifth message including any one or more of the following:

[0175] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown, or a part thereof, but not limited to it. Figure 1 The entities shown are illustrative; a communication system may include... Figure 1 All or part of the main body, or may include Figure 1 Other than the entities mentioned above, the number of each entity is arbitrary, and the connection relationship between the entities is illustrative. Entities may or may not be connected, and the connection can be in any manner, including direct or indirect connections, wired or wireless connections. In some embodiments, the communication system 100 may only include a first terminal 111 and a second terminal 112, which can be connected via a side link. Furthermore, the names of the communication system and each entity are not limited.

[0176] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0177] In this embodiment, the beam is a special transmit or receive configuration, configured and indicated by a TCI (Transmission Configuration Indicator). A TCI configuration is called a TCI state. The TCI configuration indicates a series of time-frequency resource locations. When a physical channel transmits according to the beam indicated by the TCI configuration, this channel is said to be quasi-co-located with the corresponding TCI state, where quasi-co-location can also be referred to as approximately co-located. When the UE receives the downlink beam configured by the network, it can send uplink data to the base station using mutually corresponding uplink beams based on channel heterogeneity. The UE detects the Beam Failure Detection Reference Signal (BFD-RS) and records the number of Beam Failure Indications (BFI) (BFI_COUNTER). If BFI_COUNTER reaches its maximum value (beamFailureInstanceMaxCount), a beam failure is determined, and Beam Failure Recovery (BFR) is triggered. In BFR, the UE sends an indication to the network, indicating the failed beam. Based on the indication, the network reconfigures the downlink beam.

[0178] It is worth noting that when the directions of two beams coincide, it indicates that the two beams are spatially consistent.

[0179] The network can configure the UE with a Beam Failure Detection Reference Signal (BFD-RS), candidate beams for beam recovery, and a Beam Failure Received Power (RSRP) threshold. The UE measures the BFD-RS and records the number of received Beam Failure Indications (BFI) (BFI_COUNTER). If the BFI_COUNTER reaches a preset maximum threshold, which can be set to, for example, the parameter beamFailureInstanceMaxCount, then Beam Failure Recovery (BFR) is triggered. The UE can send an indication to the network via BFR, indicating the failed beam and the beams among the candidate beams for beam recovery whose RSRP is greater than the beam recovery RSRP threshold. Based on the indication, the network reconfigures the downlink beams.

[0180] In this embodiment of the disclosure, a sidelink communication method is introduced to support direct communication between UEs, and beams can also be introduced on the sidelink. UEs communicate and receive via the beams on the sidelink. In some embodiments, after introducing beams on the sidelink, if beam transmission fails, the terminal needs to select a beam to transmit for beam failure recovery information. If the selected beam continues to fail, beam failure recovery will fail.

[0181] Figure 2a This is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure, such as... Figure 2a As shown, this disclosure relates to an information processing method for a communication system 100, the method comprising:

[0182] Step S2101: The first terminal 111 determines that the first beam communicating with the second terminal 112 has failed and determines a candidate beam.

[0183] Optionally, the candidate beams can be used for beam recovery between the first terminal and the second terminal. Optionally, the first terminal 111 can determine one or more candidate beams if it determines that the first beam communicating with the second terminal 112 has failed. Optionally, the first terminal 111 can determine one or more candidate beams in response to the first beam communication with the second terminal 112 failing. Optionally, the first terminal 111 determines one or more candidate beams when it determines that the first beam communicating with the second terminal 112 has failed.

[0184] In some embodiments, the first beam may include one or more beams, and the number of the first beam is not limited in the embodiments disclosed herein.

[0185] In some embodiments, the first terminal 111 may measure the BFD-RS corresponding to the first beam and record the number of times a beam failure indication is received (BFI_COUNTER), and determine that the first beam has failed when the value of BFI_COUNTER is greater than a preset threshold. Alternatively, the first terminal 111 may determine that the first beam has failed when the signal-to-noise ratio of the signal transmitted to the second terminal 112 through the first beam is greater than a preset threshold. This disclosure does not limit the scope of the embodiments.

[0186] In some embodiments, candidate beams are beams whose measurement results meet preset threshold conditions.

[0187] For example, if the beams that can be used for communication between the first terminal 111 and the second terminal 112 include N beams, then the beams whose measurement results satisfy the preset threshold conditions among the N beams can be selected as candidate beams.

[0188] Optionally, the first terminal 111 can detect the signal strength of the reference signal for each beam. The measurement result can be, for example, the signal strength, and the preset threshold condition can be that the signal strength is greater than a preset strength threshold. Alternatively, the first terminal 111 can measure the BFD-RS and record the number of times a beam failure indication is received (BFI_COUNTER). The measurement result can be, for example, BFI_COUNTER, and the preset threshold condition can be, for example, that BFI_COUNTER is less than a preset number threshold. Alternatively, the first terminal 111 can also measure the signal-to-noise ratio (SNR) of the information transmitted using each beam. The preset threshold condition can be, for example, that the SNR is less than a preset SNR threshold. This embodiment of the present disclosure does not limit the type of measurement result or the specific conditions of the preset threshold condition.

[0189] In some embodiments, the candidate beam is the beam with the best measurement results.

[0190] For example, if the beams that can be used for communication between the first terminal 111 and the second terminal 112 include N beams, then the beam with the highest measurement result among the N beams can be selected as the candidate beam. Alternatively, if it is determined that there are M beams whose measurement results meet a preset threshold, then the beam with the best measurement result among the M beams can be selected as the candidate beam.

[0191] Step S2102: The first terminal 111 sends the second information to the network device 120.

[0192] In some embodiments, the second information is used to report beam-related information of the first terminal 111, such as UCI (Uplink Control Information), or other information. This disclosure does not limit the name.

[0193] In some embodiments, the second information includes any one or more of the following: the beam identifier of the first beam; the beam identifier of the candidate beam; the beam identifier of the beam that uses the same TCI configuration as the first beam; the beam identifier of the beam that is quasi-co-located with the TCI configuration used by the first beam; the beam identifier of the beam that is quasi-co-located with the first beam; the beam identifier of the beam that is spatially aligned with the first beam; the beam identifier of the beam that uses the same TCI configuration as the candidate beam; the beam identifier of the beam that is quasi-co-located with the TCI configuration used by the candidate beam; the beam identifier of the beam that is quasi-co-located with the candidate beam; and the beam identifier of the beam that is spatially aligned with the candidate beam.

[0194] Optionally, the TCI configuration can be, for example, a TCI state. For example, a beam that uses the same TCI configuration as the first beam can be, for example, a beam with the same TCI state as the first beam; a beam that is quasi-co-located with the TCI configuration used by the first beam can be, for example, a beam quasi-co-located with the TCI state of the first beam.

[0195] Optionally, the beam identifier of each beam can be indicated by the network device 120 through TCI configuration. For example, the beam identifier can be a TCI state identifier, i.e., a TCI state ID, and each beam can be uniquely indicated by the TCI state identifier.

[0196] For example, the second information may only include the beam identifier of the first beam and / or the beam identifier of the candidate beam. The network device 120 can determine, based on the information in the second information, beams using the same TCI configuration as the first beam, beams quasi-co-located with the TCI configuration used by the first beam, and so on. It is understood that the specific information included in the second information can be configured by those skilled in the art according to actual needs, and this disclosure does not describe every possible combination in detail.

[0197] Step S2103: Network device 120 sends third information to first terminal 111.

[0198] In some embodiments, the third information may include one or more beam identifiers. The third information may be used to indicate a second beam for transmitting the first information. For example, the beam identifier may be used to indicate that the first terminal 111 transmits the first information through the beam corresponding to the beam identifier. The name of the third information is not limited in the embodiments of this disclosure.

[0199] In some embodiments, the third information may be determined by the network device 120 based on the second information, or the third information may be determined by the network device 120 itself; this disclosure does not limit this. For example, the beam identifier included in the third information may be determined based on the second information, or the network device 120 may determine the third information based on its own information after receiving the second information.

[0200] Step S2104: The first terminal 111 determines the second beam.

[0201] In some implementations, the first terminal 111 may determine the second beam based on third information.

[0202] For example, the first terminal 111 may determine the second beam from the beam identifier included in the third information. Alternatively, the first terminal 111 may also determine the second beam based on information it has determined itself, such as the first beam and candidate beams, as well as the third information.

[0203] In some embodiments, the second beam is not any one or more of the following: a beam that uses the same TCI configuration as the first beam; a beam that is quasi-co-located with the TCI configuration used by the first beam; a beam that is quasi-co-located with the first beam; and a beam that has spatial co-location with the first beam.

[0204] For example, if the first terminal 111 determines the second beam based on the third information, the network device 120 can determine, based on the second information reported by the first terminal 111, that the beam included in the third information is not the aforementioned beam, and instruct the first terminal 111 through the third information so that the second beam determined by the first terminal 111 is not the aforementioned beam. Alternatively, the first terminal 111 can also exclude the aforementioned beam from the beams included in the third information based on the first beam, so that the determined second beam is not the aforementioned beam.

[0205] In some embodiments, the second beam is any one or more of the following: a beam that uses the same TCI configuration as the candidate beam; a beam that is quasi-co-located with the TCI configuration used by the candidate beam; a beam that is quasi-co-located with the candidate beam; and a beam that is spatially aligned with the candidate beam.

[0206] For example, if the first terminal 111 determines the second beam based on the third information, the network device 120 can determine the beam indicated by the third information as the aforementioned beam based on the second information reported by the first terminal 111, and instruct the first terminal 111 through the third information to make the second beam determined by the first terminal 111 the aforementioned beam. Alternatively, the first terminal 111 can also determine the aforementioned beam from the beams included in the third information as the second beam based on candidate beams.

[0207] In some implementations, the first terminal 111 can determine a second beam based on a first beam and / or candidate beams. For alternative implementations of determining the second beam based on the first beam and / or candidate beams, please refer to [link to relevant documentation]. Figure 2b Step S2202.

[0208] Step S2105: The first terminal 111 sends the first information to the second terminal 112 through the second beam.

[0209] In some embodiments, the first information may be Beam Failure Recovery (BFR) information, or the first information may specifically be a Beam Failure Recovery Media Access Control Element (BFR MAC CE), such as a Sidelink Beam Failure Recovery Media Access Control Element (SL BFR MAC CE).

[0210] In some embodiments, the first information is used to indicate that a beam failure has occurred at the first terminal 111. Optionally, the first information may also be used to instruct the second terminal 112 to begin determining a third beam, or the first information may also be used to instruct the second terminal 112 to determine a third beam based on the first information. The name of the first information is not limited in the embodiments of this disclosure.

[0211] In some embodiments, the first information includes at least one of the following: the beam identifier of the first beam and the beam identifier of the candidate beam.

[0212] Optionally, the candidate beam may include one or more beams. This embodiment of the disclosure does not limit the number of candidate beams. The candidate beam may be a beam that can be used for communication between the first terminal 111 and the second terminal 112.

[0213] In some embodiments, the first information may further include one or more of the following: beam identifiers of beams using the same TCI configuration as the first beam; beam identifiers of beams quasi-co-located with the TCI configuration used by the first beam; beam identifiers of beams quasi-co-located with the first beam; beam identifiers of beams spatially aligned with the first beam; beam identifiers of beams using the same TCI configuration as the candidate beam; beam identifiers of beams quasi-co-located with the TCI configuration used by the candidate beam; beam identifiers of beams quasi-co-located with the candidate beam; and beam identifiers of beams spatially aligned with the candidate beam.

[0214] Step S2106: The second terminal 112 sends the fifth information to the network device 120.

[0215] Optionally, after receiving the first information, the second terminal 112 sends the fifth information to the network device 120. Optionally, in response to the first information, the second terminal 112 sends the fifth information to the network device 120. Optionally, the second terminal 112 sends the fifth information to the network device 120 when it receives the first information.

[0216] In some embodiments, the fifth information is used to report beam-related information of the first terminal 111, such as UCI, or other information. The names are not limited in this disclosure.

[0217] In some embodiments, the fifth information includes any one or more of the following: the beam identifier of the first beam; the beam identifier of the second beam; the beam identifier of the candidate beam; the beam identifier of the beam that uses the same TCI configuration as the first beam; the beam identifier of the beam that is quasi-co-located with the TCI configuration used by the first beam; the beam identifier of the beam that is quasi-co-located with the first beam; the beam identifier of the beam that is spatially aligned with the first beam; the beam identifier of the beam that uses the same TCI configuration as the second beam; the beam identifier of the beam that is quasi-co-located with the TCI configuration used by the second beam; the beam identifier of the beam that is quasi-co-located with the second beam; and the beam identifier of the beam that is spatially aligned with the second beam.

[0218] It is understandable that if the fifth information includes the beam identifier of the candidate beam, the beam identifier of the candidate beam may be determined by the second terminal based on the first information.

[0219] Optionally, the TCI configuration can be, for example, a TCI state. For example, a beam that uses the same TCI configuration as the first beam can be, for example, a beam with the same TCI state as the first beam; a beam that is quasi-co-located with the TCI configuration used by the first beam can be, for example, a beam quasi-co-located with the TCI state of the first beam.

[0220] Optionally, the beam identifier of each beam can be indicated by the network device 120 through TCI configuration. For example, the beam identifier can be a TCI state identifier, i.e., a TCI state ID, and each beam can be uniquely indicated by the TCI state identifier.

[0221] Optionally, the first beam and the candidate beam may be determined by the second terminal 112 based on first information. For example, the first information may include the beam identifier of the first beam and / or the beam identifier of the candidate beam.

[0222] Optionally, the second beam may also be determined by the second terminal 112 based on the first information, such as the first information may include the beam identifier of the second beam. Alternatively, the second terminal 112 may determine the second beam for transmitting the first information, for example, based on a reference signal, after receiving the first information.

[0223] It is understood that the other beams in the beams included in the fifth information above may be determined by the second terminal 112 based on the first beam and the second beam.

[0224] Step S2107: Network device 120 sends the sixth information to the second terminal 112.

[0225] In some embodiments, the sixth information may be used to indicate the third beam used to transmit the fourth information, and the name of the sixth information is not limited in this disclosure.

[0226] In some embodiments, the sixth information may include one or more beam identifiers, which can be used to instruct the second terminal 112 to transmit the fourth information through the beam corresponding to the beam identifier. Optionally, the sixth information may be determined based on the fifth information.

[0227] Step S2108: The second terminal 112 determines the third beam.

[0228] In some embodiments, the second terminal 112 may determine the third beam based on the sixth information.

[0229] Optionally, the third beam may include one or more beams, and the number of third beams is not limited in the embodiments of this disclosure.

[0230] In some embodiments, the second terminal 112 may further determine the third beam based on the sixth information and the first information.

[0231] For example, the sixth information may include beam identifiers of one or more beams, and the second terminal 112 may determine the beam corresponding to the beam identifier as the third beam. Alternatively, the sixth information may include beam identifiers of one or more beams, and the second terminal 112 may also, based on the first information, exclude some beam identifiers included in the sixth information and determine the beam corresponding to the excluded beam identifiers as the third beam.

[0232] In some embodiments, the third beam is any one or more of the following: a candidate beam; a beam that uses the same TCI configuration as the second beam; a beam that is quasi-co-located with the TCI configuration used by the second beam; a beam that is quasi-co-located with the second beam; and a beam that is spatially aligned with the second beam.

[0233] For example, if the second terminal 112 determines the second beam based on the sixth information, the network device 120 can determine the beam indicated by the sixth information as the aforementioned beam based on the fifth information reported by the second terminal 112, and instruct the second terminal 112 through the sixth information so that the second terminal 112 determines the obtained third beam as the aforementioned beam. Alternatively, the second terminal 112 can first determine the second beam based on the first information, and based on the second beam, determine the aforementioned beam in the beam corresponding to the sixth information as the third beam, so that the third beam determined by the second terminal 112 is the aforementioned beam.

[0234] In some embodiments, the third beam is not any one or more of the following: the first beam; a beam using the same TCI configuration as the first beam; a beam quasi-co-located with the TCI configuration used by the first beam; a beam quasi-co-located with the first beam; and a beam spatially aligned with the first beam. This avoids identifying a failed beam or a beam close to a failed beam as the third beam, effectively preventing further failure of the third beam and thus ensuring the reliability of communication between the first terminal 111 and the second terminal 112.

[0235] For example, if the second terminal 112 determines the second beam based on the sixth information, the network device 120 can determine, based on the fifth information reported by the second terminal 112, that the beam indicated by the sixth information is not the aforementioned beam, and instruct the second terminal 112 through the sixth information so that the third beam determined by the second terminal 112 is not among the aforementioned beams. Alternatively, the second terminal 112 can first determine the second beam based on the first information, and based on the second beam, exclude the aforementioned beam from the beam corresponding to the sixth information, so that the third beam determined by the second terminal 112 is not the aforementioned beam.

[0236] In other embodiments, during the first timer operation period, the third beam is not any one or more of the following: the first beam; a beam using the same TCI configuration as the first beam; a beam quasi-co-located with the TCI configuration used by the first beam; a beam quasi-co-located with the first beam; and a beam having spatial co-location with the first beam.

[0237] Optionally, the first timer may be, for example, a beam recovery timer, which can be used for beam recovery timing.

[0238] Optionally, the second terminal 112 may not identify the third beam as the aforementioned beam during the operation of the first timer, and may identify the third beam as the aforementioned beam outside the operation of the first timer.

[0239] The first timer can be a hardware timing device or a software-implemented timing module. For example, after starting, the first timer can run continuously for a preset duration and then end the timing. The preset duration can be set according to actual needs, and this embodiment does not limit the preset duration.

[0240] It is understandable that a failed beam may recover after a period of time. Using this scheme, by setting a first timer, a beam close to the failed beam can be used as the third beam after a certain period.

[0241] Optionally, the first information may also be used to instruct the second terminal 112 to start a first timer. For example, the second terminal 112 may start the first timer after determining that it has received the first information sent by the first terminal 111, so that the first timer begins counting. In this way, the first timer can be triggered immediately upon receiving the first information.

[0242] Alternatively, the first timer may be started after the second terminal 112 sends the fifth message to the network device 120. Or, the first timer may be started after receiving the sixth message sent by the network device 120.

[0243] Optionally, the first timer is sent to the second terminal 112 by the first terminal 111 or the network device 120, or the first timer is obtained by the second terminal 112 from a pre-configuration. For example, the first terminal 111 can send the first timer to the second terminal 112 via first information, the network device 120 can send the first timer to the second terminal 112 via sixth information, or the second terminal 112 can obtain the first timer from its own stored pre-configuration. Optionally, the first terminal 111 or the network device 120 can send parameter information of the first timer, such as a preset duration corresponding to the first timer, so that the second terminal 112 obtains the first timer. Specifically, the second terminal 112 obtaining the first timer from the pre-configuration can involve obtaining the parameter information of the first timer from the pre-configuration.

[0244] In some embodiments, the second terminal 112 may also determine a third beam based on the first information and / or the second beam. For optional implementations of the second terminal 112 determining the third beam based on the first information and / or the second beam, please refer to [link to relevant documentation]. Figure 2b The optional implementation methods of step S2204 will not be elaborated here.

[0245] Step S2109: The second terminal 112 sends the fourth information to the first terminal 111 through the third beam.

[0246] Optionally, the third beam can be considered as the beam after the second terminal 112 performs beam failure recovery after determining that the first beam has failed.

[0247] Optionally, the fourth information can be any sidelink data or signaling, or the fourth information can be used to carry any sidelink data or signaling. The name of the fourth information is not limited in the embodiments of this disclosure.

[0248] In some embodiments, if the first terminal receives the fourth information, it can determine that the beam failure recovery is complete.

[0249] In the embodiments disclosed herein, each step can be implemented as an independent embodiment. Steps S2104 and S2108 can be implemented as independent embodiments, as can steps S2103 and S2104, as can steps S2107 and S2108, as can steps S2101 to S2105, as can steps S2106 to S2109, but are not limited thereto.

[0250] In some embodiments, steps S2101 to S2103 and steps S2104 to S2109 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0251] In some embodiments, steps S2101 to S2107 and step S2109 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0252] In some embodiments, steps S2101 to S2105 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0253] In some embodiments, steps S2106 to S2109 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0254] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0255] In this embodiment of the present disclosure, when the first terminal 111 determines that the beam transmission of the communication beam with the second terminal 112 has failed, it can report the beam-related information of the first terminal 111 to the network device 120. Then, based on the network instruction, it determines a second beam for sending beam failure recovery information, and enables the first terminal 111 to reliably send the beam failure recovery information to the second terminal 112 based on the second beam. This enables the second terminal 112 to report the beam-related information of the second terminal 112 to the network device 120, and then, based on the network instruction, determines a third beam, and enables the second terminal 112 to reliably send communication data or information to the first terminal 111 based on the third beam. This allows for timely and reliable beam failure recovery when beam failure occurs between the first terminal 111 and the second terminal 112, ensuring reliable communication between the first terminal 111 and the second terminal 112.

[0256] Figure 2b This is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure, such as... Figure 2b As shown, this disclosure relates to an information processing method for a communication system 100, the method comprising:

[0257] Step S2201: The first terminal 111 determines that the first beam communicating with the second terminal 112 has failed and determines a candidate beam.

[0258] For optional implementations of step S2201, please refer to... Figure 2a The optional implementation methods corresponding to step S2101 shown will not be described in detail here.

[0259] Step S2202: The first terminal 111 determines the second beam based on the first beam and / or candidate beams.

[0260] In some embodiments, the second beam is not any one or more of the following: a beam that uses the same TCI configuration as the first beam; a beam that is quasi-co-located with the TCI configuration used by the first beam; a beam that is quasi-co-located with the first beam; and a beam that has spatial co-location with the first beam.

[0261] For example, after determining that the first beam transmission beam has failed, the first terminal 111 can, based on the first beam, not use the aforementioned beam as the second beam.

[0262] In some embodiments, the second beam is any one or more of the following: a beam that uses the same TCI configuration as the candidate beam; a beam that is quasi-co-located with the TCI configuration used by the candidate beam; a beam that is quasi-co-located with the candidate beam; and a beam that is spatially aligned with the candidate beam.

[0263] In some embodiments, candidate beams are beams whose measurement results meet preset threshold conditions.

[0264] For example, if the beams that can be used for communication between the first terminal 111 and the second terminal 112 include N beams, then the beams whose measurement results satisfy the preset threshold conditions among the N beams can be selected as candidate beams.

[0265] Optionally, the first terminal 111 can detect the signal strength of the reference signal for each beam. The measurement result can be, for example, the signal strength, and the preset threshold condition can be that the signal strength is greater than a preset strength threshold. Alternatively, the first terminal 111 can measure the BFD-RS and record the number of times a beam failure indication is received (BFI_COUNTER). The measurement result can be, for example, BFI_COUNTER, and the preset threshold condition can be, for example, that BFI_COUNTER is less than a preset number threshold. Alternatively, the first terminal 111 can also measure the signal-to-noise ratio (SNR) of the information transmitted using each beam. The preset threshold condition can be, for example, that the SNR is less than a preset SNR threshold. This embodiment of the present disclosure does not limit the type of measurement result or the specific conditions of the preset threshold condition.

[0266] For example, if the beams that can be used for communication between the first terminal 111 and the second terminal 112 include N beams, then the beam with the highest measurement result among the N beams can be selected as the candidate beam.

[0267] Step S2203: The first terminal 111 sends the first information to the second terminal 112 through the second beam.

[0268] For optional implementations of step S2203, please refer to... Figure 2a The optional implementation corresponding to step S2105 shown can also be found in [the following text is incomplete and requires further context]. Figure 2a Other related parts of the embodiments involved will not be described in detail here.

[0269] Step S2204: The second terminal 112 receives the first information and determines the third beam based on the first information and / or the second beam.

[0270] Optionally, the third beam may include one or more beams, and the number of third beams is not limited in the embodiments of this disclosure.

[0271] Optionally, the second terminal 112 may determine a third beam in response to receiving the first information. Optionally, the second terminal 112 may determine the third beam when it receives the first information. Optionally, the second terminal 112 may determine the third beam in response to receiving the first information.

[0272] In some embodiments, the second terminal 112 may determine the third beam based on the first information and / or information determined by itself.

[0273] In some embodiments, the third beam is any one or more of the following: a candidate beam; a beam that uses the same TCI configuration as the second beam; a beam that is quasi-co-located with the TCI configuration used by the second beam; a beam that is quasi-co-located with the second beam; and a beam that is spatially aligned with the second beam.

[0274] For example, if the first information does not include the beam identifier of the candidate beam, the third beam can be determined based on the second beam. Optionally, the first information may also include the beam identifier of the second beam, and the second terminal can determine the second beam based on the beam identifier, and then determine the third beam based on the second beam. Alternatively, the second beam may be determined by the second terminal 112 itself based on a reference signal or other means.

[0275] In one possible implementation, the second terminal 112 may first determine the second beam, for example, based on a reference signal or based on first information, and then determine the third beam as the aforementioned beam based on the second beam.

[0276] For example, if the first information includes the beam identifier of at least one candidate beam, the third beam may be determined based on the at least one candidate beam, for example, the third beam may be any one or more beams among the at least one candidate beam.

[0277] Optionally, the third beam can also be the beam with the best measurement results among at least one candidate beam.

[0278] In some embodiments, the third beam is not any one or more of the following: the first beam; a beam that uses the same TCI configuration as the first beam; a beam that is quasi-co-located with the TCI configuration used by the first beam; a beam that is quasi-co-located with the first beam; and a beam that has spatial co-location with the first beam.

[0279] For example, the second terminal 112 can determine the first beam based on the beam identifier of the first beam included in the first information, and determine that the third beam is not the aforementioned beam.

[0280] In other embodiments, during the first timer operation period, the third beam is not any one or more of the following: the first beam; a beam using the same TCI configuration as the first beam; a beam quasi-co-located with the TCI configuration used by the first beam; a beam quasi-co-located with the first beam; and a beam having spatial co-location with the first beam.

[0281] Optionally, the second terminal 112 may not identify the third beam as the aforementioned beam during the operation of the first timer, and may identify the third beam as the aforementioned beam outside the operation of the first timer.

[0282] The first timer can be a hardware timing device or a software-implemented timing module. For example, after starting, the first timer can run continuously for a preset duration and then end the timing. The preset duration can be set according to actual needs, and this embodiment does not limit the preset duration.

[0283] Optionally, the first information is also used to instruct the second terminal 112 to start a first timer. For example, the second terminal 112 may start the first timer after determining that it has received the first information sent by the first terminal 111, so that the first timer begins counting.

[0284] Alternatively, the first timer may be started after the second terminal 112 sends the fifth message to the network device 120. Or, the first timer may be started after receiving the sixth message sent by the network device 120.

[0285] Optionally, the first timer is sent to the second terminal 112 by the first terminal 111 or the network device 120, or the first timer is obtained by the second terminal 112 from a pre-configuration. For example, the first terminal 111 can send the first timer to the second terminal 112 via first information, the network device 120 can send the first timer to the second terminal 112 via sixth information, or the second terminal 112 can obtain the first timer from its own stored pre-configuration. Optionally, the first terminal 111 or the network device 120 can send parameter information of the first timer, such as a preset duration corresponding to the first timer, so that the second terminal 112 obtains the first timer. Specifically, the second terminal 112 obtaining the first timer from the pre-configuration can involve obtaining the parameter information of the first timer from the pre-configuration.

[0286] Step S2205: The second terminal 112 sends the fourth information to the first terminal 111 through the third beam.

[0294] In this embodiment of the present disclosure, when the first terminal 111 determines that the beam transmission beam for communication with the second terminal 112 has failed, it can determine a second beam for transmitting beam failure recovery information, and enable the first terminal 111 to reliably transmit the beam failure recovery information to the second terminal 112 based on the second beam. After receiving the beam failure recovery information, the second terminal 112 can determine a third beam, and enable the second terminal 112 to reliably transmit communication data or information to the first terminal 111 based on the third beam. This enables timely and reliable beam failure recovery when beam failure occurs between the first terminal 111 and the second terminal 112, ensuring reliable communication between the first terminal 111 and the second terminal 112.
