Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0127] In some embodiments, the link for direct communication between terminals is PC-5. The interface between the terminals is PC-5. Based on the correspondence between the sending and receiving terminals, three transmission modes are supported on the sidelink: unicast, multicast, and broadcast. The sending terminal sends sidelink control information (SCI) on the physical sidelink control channel (PSCCH) and sends the second-stage SCI on the physical sidelink shared channel (PSSCH), which carries the resource location of the transmitted data and the source and destination identifiers. For data packets with hybrid automatic repeat request (HARQ) feedback enabled, the receiving terminal performs hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback on the physical sidelink feedback channel (PSFCH) for the PSSCH.

[0128] In some embodiments, sidelink communication has two transmission resource allocation modes: one is the network dynamic scheduling mode (mode 1, also called the first resource allocation mode), and the other is the terminal autonomous selection mode from the network configured or pre-configured resource pool (mode 2, also called the second resource allocation mode). Dynamic scheduling means that the network dynamically allocates transmission resources on the sidelink to the terminal based on the terminal's cached data report, while autonomous selection means that the terminal randomly selects transmission resources from the network configured or pre-configured resource pool. The network can configure multiple resource pools for the terminal on a BWP (Bandwidth Part). The specific allocation mode to be used is configured by the network side through RRC (Radio Resource Control) signaling.

[0129] It should be noted that a beam is a special transmission or reception configuration, including uplink and downlink beams, used for uplink transmission and downlink reception by the terminal, respectively. Beams are directional, which can improve resource utilization and reduce interference. In Uu-FR2 (Uni-band Frequency Range 2), to achieve highly directional transmission links, the base station (such as a gNB) and the terminal need to establish an initial beam pair, such as a TX (transmit) beam and an RX (receive) beam. Due to the highly directional transmission of extremely narrow beams, the base station can transmit multiple TX beams, which can be detected by the terminal. All of these detected beams can potentially be used for communication. The purpose of initial beam pairing is to determine the TX-RX beam pair for communication. Initial beam pairing is a terminal-side behavior. Through beam training, the optimal TX beam with the best RX beam is found. The optimal TX-RX pair is initially used for RACH (Random Access Channel), thereby establishing a communication link between the terminal and the network over the optimal TX-RX pair.

[0130] In Uu-FR2, after the initial beam pairing, the base station and the terminal can transmit and receive through the paired TX beam and RX beam. Due to fluctuations in channel quality or migration of the terminal within the cell, the terminal needs to maintain the beam pair to ensure link connectivity. In the beam management framework implemented in Uu, the update of the beam pair is based on periodic SSB (Synchronization Signal / PBCH Block) and / or CSI-RS (Channel State Information-Reference Signal) measurements through beam scanning. The base station periodically sends SSB and / or CSI-RS measurement and reporting configurations to the terminal, and instructs the terminal to measure the SSB and / or CSI-RS beams, and the terminal reports the beam quality indicators of the CSI-RS, SSB or both signals to the base station. After receiving the measurement report including SSB and / or CSI-RS, the base station determines the TX beam suitable for transmitting the downlink signal.

[0131] In Uu-FR2, beam asymmetry may occur due to channel fluctuations, obstacles or terminal mobility. Beam asymmetry means that the signal quality received in the current beam pair is worse than expected by the physical layer. For beam failure detection of the beam pair, the base station configures a beam failure detection reference signal (SSB or CSI-RS) for the terminal. The terminal performs beam failure detection on the beam failure detection reference signal (SSB or CSI-RS) set and records the number of beam failure indications (BFI) (such as BFI_COUNTER). Before the configured timer expires, when the number of beam failures BFI_COUNTER displayed by the physical layer reaches the configured threshold, the terminal determines that a beam failure has occurred and beam failure recovery (BFR) is required.

[0132] Optionally, if the BFR is in a PCell (Primary Cell), the terminal performs the following operations:

[0133] 1) Triggering beam failure recovery by initiating a random access procedure on the PCell;

[0134] 2) Select an appropriate beam to perform beam failure recovery;

[0135] 3) After the random access procedure is completed, the beam failure recovery of the PCell is considered complete.

[0136] Optionally, if the BFR is in a SCell (Secondary Cell), the terminal performs the following operations:

[0137] 1) Triggering beam failure recovery by initiating a BRF MAC CE transmission; the BRF MAC CE contains a failed beam indication and candidate beams;

[0138] 2) When a PDCCH is received indicating a new transmission uplink grant for the HARQ process scheduled for BFR MAC CE transmission, beam failure recovery for this SCell is considered complete.

[0139] In Uu-FR2, if the BFR MAC CE is triggered but there are no available uplink resources, the terminal triggers an SR (scheduling request). Uu-FR2 defines a dedicated SR configuration for BFR.

[0140] It should be noted that beam failure recovery is also required in the sidelink communication scenario. In some embodiments, the receiving terminal (RX UE) can perform sidelink beam failure detection based on certain SL reference signals. If SLBFR (sidelink beam failure) occurs on the PC5 link, the RX UE needs to send the SL BFR MAC CE (Sidelink Beam Failure Recovery Media AccessControl Control Element) to the transmitting terminal (TX UE) to assist the TX UE in performing SL beam failure recovery. The TX UE in the RRC connected state may need to report the SL BFR MAC CE to the network device to assist the network device in performing SL beam failure recovery.

[0141] However, how to trigger beam failure recovery through SL BFR MAC CE transmission in sidelink communication scenarios has become an urgent problem to be solved.

[0142] To this end, the embodiments of the present disclosure provide an information processing method and device thereof, which can determine the order of the logical channel priority of the SL BFR MAC CE sent on the SL resource through the first terminal, so that the SL BFR MAC CE is sent to the second terminal according to the order to trigger beam failure recovery, thereby assisting the second terminal in performing SL beam failure recovery, solving the problem of unclear logical channel priority of the SL BFR MAC CE sent on the SL resource, thereby ensuring communication quality.

[0143] FIG2A is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in FIG2A , the information processing method according to an embodiment of the present disclosure can be applied to a communication system 100 , and the method includes but is not limited to the following steps.

[0144] In step S2101 , the first terminal 101 determines that a sidelink beam failure (SL BFR) occurs in the PC5 link between the first terminal 101 and the second terminal 102 .

[0145] Among the terminals for sidelink communication, they can be divided into transmitting terminals (TX UE) and receiving terminals (RX UE) according to the classification of transmission and reception. In some embodiments, the first terminal 101 can be a receiving terminal, and the second terminal 102 can be a transmitting terminal. Exemplarily, based on the RX (receive) detection beam failure scenario, the receiving terminal determines that SL BFR occurs on the PC5 link between the receiving terminal and the transmitting terminal, and the receiving terminal needs to send the SL BFR MAC CE to the transmitting terminal to assist the transmitting terminal in performing SL beam failure recovery. Before the receiving terminal sends the SL BFR MAC CE to the transmitting terminal, it is necessary to first determine the order of the logical channel priority of the SL BFR MAC CE sent on the SL resource.

[0146] In some embodiments, the first terminal 101 may perform sidelink beam failure detection based on the SL reference signal to determine whether a sidelink beam failure occurs in the PC5 link between the first terminal 101 and the second terminal 102. Exemplarily, the SL reference signal may include, but is not limited to, at least one of the following: S-CSI-RS; S-SSB (sidelink synchronization signal block).

[0147] For example, assuming that first terminal 101 can be a receiving terminal and second terminal 102 can be a transmitting terminal, the receiving terminal detects whether a sidelink beam failure has occurred in the PC5 link between the receiving terminal and the transmitting terminal using the SL reference signal, and records the number of sidelink beam failure indications. Before a configured timer expires, if the number of sidelink beam failures indicated by the physical layer of the receiving terminal reaches a configured threshold, the receiving terminal determines that a sidelink beam failure has occurred in the PC5 link between the receiving terminal and the transmitting terminal.

[0148] In step S2102 , the first terminal 101 determines the order of logical channel priorities of the SL BFR MAC CE (Sidelink BFR Reporting MAC CE) sent on the SL resource.

[0149] In some embodiments, the above-mentioned SL BFR MAC CE may include but is not limited to at least one of the following: a failed beam indication; a candidate beam.

[0150] In some embodiments, beam failure recovery may be triggered by the SL BFR MAC CE. In some embodiments, when a sidelink beam failure occurs in the PC5 link between the first terminal 101 and the second terminal 102, the first terminal 101 may send the SL BFR MAC CE to the second terminal 102, and the SL BFR MAC CE may assist the second terminal 102 in performing SL beam failure recovery.

[0151] In some embodiments, before sending the above-mentioned SL BFR MAC CE to the second terminal 102, the first terminal 101 needs to determine the order of the logical channel priority of the SL BFR MAC CE sent on the SL resource. Optionally, the order of the logical channel priority of the SL BFR MAC CE sent on the SL resource can be determined at any position in the SL MAC PDU, or the order of the logical channel priority of the SL BFR MAC CE sent on the SL resource can be determined at a high priority position in the SL MAC PDU, so that the first terminal 101 can send the SL BFR MAC CE to the second terminal 102 according to the order of the logical channel priority, so as to assist the second terminal 102 in performing SL beam failure recovery.

[0152] In some embodiments, the first terminal 101 determines that the logical channel priority of the SL BFR MAC CE sent on the SL resource is ranked between the SLCSI (Channel State Information) MAC CE and the data from the SCCH (Sidelink Control Channel). Exemplarily, the SL BFR MAC CE can be multiplexed into the SL MAC PDU for transmission. When the SL MAC PDU is packaged, the SCCH data (data from SCCH) can be placed first, followed by the SL BFR MAC CE, SLCSIMAC CE (Sidelink CSI Reporting MAC CE), SL terminal internal collaboration IUC request MAC CE (Sidelink Inter-UE Coodination Request MAC CE) and SL IUC information MAC CE (Sidelink Inter-UE Coodination Information MAC CE), SL DRX command MAC CE (Sidelink DRX Command MAC CE), any STCH (Sidelink Traffic Channe, sidelink traffic channel) data (data from any STCH), and finally other lower priority data. Therefore, by determining that the logical channel priority of the SL BFR MAC CE is sorted between the SL CSI MAC CE and the data from the SCCH, it is convenient to determine the position of the SL BFR MAC CE in the SL MAC PDU when packaging the SL MAC PDU, thereby solving the problem of unclear logical channel priority of the SL BFR MAC CE sent on the SL resources.

[0153] In some embodiments, the first terminal 101 determines that the logical channel priority of the SL BFR MAC CE sent on the SL resource is ranked between the SLCSIMAC CE and the first information; wherein the first information includes the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE. Exemplarily, the SL BFR MAC CE can be multiplexed into the SL MAC PDU for transmission. When the SL MAC PDU is packaged, the SCCH data can be placed first, followed by the SLCSIMAC CE, the SL BFR MAC CE, the first information (such as the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE), the SL DRX command MAC CE, the data of any STCH, and finally the data of other lower priorities. Therefore, by determining that the logical channel priority of the SL BFR MAC CE is ranked between the SLCSIMAC CE and the above-mentioned first information, it is convenient to determine the position of the SL BFR MAC CE in the SL MAC PDU when packaging the SL MAC PDU, thereby solving the problem of unclear logical channel priority of the SL BFR MAC CE sent on the SL resources.

[0154] In some embodiments, the first terminal 101 determines that the logical channel priority of the SL BFR MAC CE sent on the SL resource is sorted between the first information and the SLDRX command MAC CE; wherein the first information includes the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE. Exemplarily, the SL BFR MAC CE can be multiplexed into the SL MAC PDU for transmission. When the SL MAC PDU is packaged, the SCCH data can be placed first, followed by the SLCSIMAC CE, the first information (such as the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE), the SL BFR MAC CE, the SL DRX command MAC CE, the data of any STCH, and finally the data of other lower priorities. Therefore, by determining that the logical channel priority of the SL BFR MAC CE is sorted between the SLDRX command MAC CE and the above-mentioned first information, it is convenient to determine the position of the SL BFR MAC CE in the SL MAC PDU when packaging the SL MAC PDU, thereby solving the problem of unclear logical channel priority of the SL BFR MAC CE sent on the SL resources.

[0155] In some embodiments, the first terminal 101 determines that the logical channel priority of the SL BFR MAC CE sent on the SL resource is ranked between the SL DRX command MAC CE and the data from any sidelink service channel STCH. Exemplarily, the SL BFR MAC CE can be multiplexed into the SL MAC PDU for transmission. When the SL MAC PDU is grouped, the SCCH data can be placed first, followed by the SLCSIMAC CE, the first information (such as the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE), the SL DRX command MAC CE, the SL BFR MAC CE, the data of any STCH, and finally the data of other secondary priorities. Therefore, by determining that the logical channel priority of the SL BFR MAC CE is ranked between the SLDRX command MAC CE and the STCH data, it is convenient to determine the position of the SL BFR MAC CE in the SL MAC PDU when the SL MAC PDU is grouped, thereby solving the problem of unclear logical channel priority of the SL BFR MAC CE sent on the SL resource.

[0156] In some embodiments, the value of the logical channel priority of the SL BFR MAC CE sent on the above-mentioned SL resource is a first value. In some embodiments, the first value may be 1, or the first value represents the highest priority. Exemplarily, the value of the logical channel priority of the SL BFR MAC CE sent on the SL resource may be 1. Alternatively, the value of the logical channel priority of the SL BFR MAC CE may also be other values, such as 2, etc., which is not specifically limited in the present disclosure. Exemplarily, the smaller the value of the logical channel priority of the SL BFR MAC CE sent on the above-mentioned SL resource, the higher the logical channel priority of the SL BFR MAC CE, and thus the higher the ranking of the logical channel priority of the SL BFR MAC CE.

[0157] In some embodiments, the SL BFR MAC CE sent on the above-mentioned SL resource can be sent by the first terminal 101 to the second terminal 102 in a unicast manner, or can be sent in a multicast or broadcast manner.

[0158] In some embodiments, the sidelink transmission resource allocation mode of the first terminal is a first resource allocation mode or a second resource allocation mode, wherein the first resource allocation mode is that the network device schedules the sidelink transmission resource; and the second resource allocation mode is that the terminal autonomously selects the sidelink transmission resource.

[0159] In some embodiments, the first terminal may be in any of the following states: RRC connected (RRC CONNECTED) state; RRC idle (RRC IDLE) state; RRC inactive (RRC INACTIVE) state, OOC (out of coverage) state.

[0160] Step S2103: The first terminal 101 sends a SL BFR MAC CE.

[0161] In some embodiments, the SL BFR MAC CE may be sent by the first terminal 101 to the second terminal 102. In some embodiments, the first terminal 101 sends the SL BFR MAC CE to the second terminal 102. The second terminal 102 receives the SL BFR MAC CE sent by the first terminal 101.

[0162] In some embodiments, during the LCP process, the first terminal 101 sends the SL BFR MAC CE to the second terminal 102 on the SL resource according to the order of the logical channel priority of the SL BFR MAC CE sent on the SL resource, so as to assist the second terminal 102 in performing SL beam failure recovery.

[0163] In some embodiments, the first terminal 101 may send the SL BFR MAC CE to the second terminal 102 via unicast.

[0164] In some embodiments, the first terminal 101 may send the SL BFR MAC CE to the second terminal 102 by broadcasting;

[0165] In some embodiments, the first terminal 101 may send the above-mentioned SL BFR MAC CE to the second terminal 102 via multicast.

[0166] In some embodiments, the second terminal 102 can receive the SL BFR MAC CE sent by the first terminal 101 through the SL resource, wherein the SL BFR MAC CE is sent after an SL beam failure occurs in the PC5 link between the first terminal 101 and the second terminal 102, and the logical channel priority of the SL BFR MAC CE sent on the SL resource is determined.

[0167] In some embodiments, the logical channel priority of the SL BFR MAC CE sent on the SL resource is ranked between the SL CSI MAC CE and the data from the SCCH.

[0168] In some embodiments, the logical channel priority of the SL BFR MAC CE sent on the SL resource is ranked between the SLCSIMAC CE and the first information; wherein the first information includes the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE.

[0169] In some embodiments, the logical channel priority of the SL BFR MAC CE sent on the SL resource is sorted between the first information and the SLDRX command MAC CE; wherein the first information includes the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE.

[0170] In some embodiments, the logical channel priority of the SL BFR MAC CE sent on the SL resource is ordered between the SL DRX command MAC CE and data from any sidelink traffic channel STCH.

[0171] It should be noted that, in some embodiments, the above steps S2101 and S2102 can be exchanged in order or performed simultaneously. For example, step S2101 can be performed first and then step S2102. For example, when the first terminal 101 determines that a sidelink beam failure occurs in the PC5 link between the first terminal 101 and the second terminal 102, the first terminal 101 determines the ranking of the logical channel priorities of the SL BFR MAC CE sent on the SL resource. Alternatively, step S2102 can be performed first and then step S2101. If a sidelink beam failure occurs in the PC5 link between the first terminal 101 and the second terminal 102 after the first terminal 101 determines the ranking of the logical channel priorities of the SL BFR MAC CE sent on the SL resource, the first terminal 101 sends the above-mentioned SL BFR MAC CE to the second terminal 102. Alternatively, step S2101 and step S2102 can be performed simultaneously. This disclosure is not limited to this.

[0172] Step S2104: The second terminal 102 determines the order of logical channel priorities of the SL BFR MAC CE sent on the Uu resource.

[0173] In some embodiments, the above-mentioned SL BFR MAC CE may include but is not limited to at least one of the following: a failed beam indication; a candidate beam.

[0174] In some embodiments, the SL BFR MAC CE sent on the Uu resource is sent by the second terminal 102 to the network device 103. In some embodiments, the sidelink transmission resource allocation mode of the second terminal 102 is the first resource allocation mode or the second resource allocation mode, and the second terminal 102 is in an RRC connected state; wherein the first resource allocation mode is that the network device schedules the sidelink transmission resource; and the second resource allocation mode is that the terminal autonomously selects the sidelink transmission resource.

[0175] Exemplarily, the second terminal 102 in the RRC connected state can send the SL BFR MAC CE to the network device 103 to assist the network device 103 in performing SL beam failure recovery. Therefore, the second terminal 102 needs to determine the order of the logical channel priority of the SL BFR MAC CE sent on the Uu resource, so that the second terminal 102 can send the SL BFR MAC CE to the network device 103 on the Uu resource.

[0176] In some embodiments, the SL BFR MAC CE sent by the second terminal 102 on the Uu resource may be sent by the first terminal 101 to the second terminal 102. That is, the second terminal 102 receives the SL BFR MAC CE sent by the first terminal 101, and the second terminal 102 may send the SL BFR MAC CE to the network device 103 on the Uu resource to assist the network device 103 in performing SL beam failure recovery. Before the second terminal 102 sends the SL BFR MAC CE to the network device 103, it is necessary to determine the order of the logical channel priorities of the SL BFR MAC CE sent on the Uu resource.

[0177] In some embodiments, the second terminal 102 determines that the logical channel priority of the SL BFR MAC CE sent on the air interface Uu resource is ranked between the second information and the Sidelink Configured Grant Confirmation MAC CE.

[0178] In some embodiments, the above-mentioned second information includes at least one of the following: BFRMAC CE (MAC CE for (Enhanced) BRF, Beam Failure Recovery MAC CE); Configured Grant Confirmation MAC CE (MAC CE for Configured Grant Confirmation, Configured Grant Confirmation MAC CE); Multiple Entry Configured Grant Confirmation MAC CE (MAC CE for Multiple Entry Configured Grant Confirmation, Multiple Entry Configured Grant Confirmation MAC CE). Exemplarily, the SL BFR MAC CE sent on the Uu resource can be multiplexed into the MAC PDU for transmission. When the MAC PDU is packaged, the third information (such as MAC CE for C-RNTI (MAC CE carrying C-RNTI), or data from UL-CCCH (data of the uplink common control channel)) can be placed first, followed by the above-mentioned second information (such as MAC CE for (Enhanced) BRF (BFRMAC CE), or MAC CE for Configured Grant Confirmation (MAC CE carrying configuration authorization confirmation), or MAC CE for Multiple Entry Configured Grant Confirmation (MAC CE carrying multiple entry configuration authorization confirmation)), SL BFR MAC CE (MAC CE for Sidelink BFR, MAC CE carrying sidelink beam failure recovery), MAC CE for Sidelink Configured Grant Confirmation (MAC CE carrying sidelink configuration authorization confirmation), MAC CE for LBT failure (MAC CE carrying listen-before-talk failure indication), and finally other MAC CEs of lower priority. CE and / or data.

[0179] In some embodiments, the value of the logical channel priority of the SL BFR MAC CE sent on the above-mentioned Uu resource can be a second value. For example, the second value can be 1, or the second value represents the highest priority, or it can also be other values. This disclosure does not make any specific limitations on this.

[0180] Step S2105 : The second terminal 102 sends the SL BFR MAC CE to the network device 103 .

[0197] Figure 2B is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2B, the information processing method according to an embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0198] Step S2201 : The second terminal 102 determines that SL BFR occurs on the PC5 link between the second terminal 102 and the first terminal 101 .

[0199] Among the terminals for sidelink communication, they can be divided into transmitting terminals (TX UE) and receiving terminals (RX UE) according to the classification of transmission and reception. In some embodiments, the first terminal 101 can be a receiving terminal, and the second terminal 102 can be a transmitting terminal. Exemplarily, based on the TX (transmit) detection beam failure scenario, the transmitting terminal determines that SL BFR occurs on the PC5 link between the transmitting terminal and the receiving terminal, and the transmitting terminal needs to send an SL BFR MAC CE to the receiving terminal to assist the receiving terminal in avoiding selecting these failed beams when the receiving terminal acts as a transmitting terminal. Before the transmitting terminal sends the SL BFR MAC CE to the receiving terminal, it is necessary to first determine the order of the logical channel priority of the SL BFR MAC CE sent on the SL resource.

[0200] In some embodiments, the second terminal 102 may perform sidelink beam failure detection based on the SL reference signal to determine whether a sidelink beam failure occurs in the PC5 link between the second terminal 102 and the first terminal 101. Exemplarily, the SL reference signal may include, but is not limited to, at least one of the following: an S-CSI-RS; or an S-SSB.

[0201] For example, assuming that first terminal 101 can be a receiving terminal and second terminal 102 can be a transmitting terminal, the transmitting terminal detects whether a sidelink beam failure has occurred in the PC5 link between the transmitting terminal and the receiving terminal using the SL reference signal, and records the number of sidelink beam failure indications. Before a configured timer expires, if the number of sidelink beam failures indicated by the physical layer of the transmitting terminal reaches a configured threshold, the transmitting terminal determines that a sidelink beam failure has occurred in the PC5 link between the transmitting terminal and the receiving terminal.

[0202] Step S2202: The second terminal 102 determines the order of logical channel priorities of the SLBFRMACCE sent on the SL resources.

[0203] In some embodiments, the above-mentioned SL BFR MAC CE may include but is not limited to at least one of the following: a failed beam indication; a candidate beam.

[0204] In some embodiments, beam failure recovery may be triggered by the SL BFR MAC CE. In some embodiments, when the second terminal 102 determines that a sidelink beam failure has occurred in the PC5 link between the second terminal 102 and the first terminal 101, the second terminal 102 may send the SL BFR MAC CE to the first terminal 101. The SL BFR MAC CE may assist the receiving terminal in avoiding selecting the failed beams when the receiving terminal acts as a transmitting terminal.

[0205] In some embodiments, before sending the above-mentioned SL BFR MAC CE to the first terminal 101, the second terminal 102 needs to determine the order of the logical channel priority of the SL BFR MAC CE sent on the SL resource, so that the second terminal 102 can send the SL BFR MAC CE to the first terminal 101 according to the order of the logical channel priority.

[0206] In some embodiments, the second terminal 102 determines that the logical channel priority of the SL BFR MAC CE sent on the SL resource is ranked between the SL CSI MAC CE and the data from the SCCH. Exemplarily, the SL BFR MAC CE can be multiplexed into the SL MAC PDU for transmission. When the SL MAC PDU is packaged, the SCCH data can be placed first, followed by the SL BFR MAC CE, the SLCSI MAC CE, the SL terminal internal collaboration IUC request MAC CE and the SL IUC information MAC CE, the SL DRX command MAC CE, the data of any STCH, and finally the data of other lower priorities.

[0207] In some embodiments, the second terminal 102 determines that the logical channel priority of the SL BFR MAC CE sent on the SL resource is ranked between the SLCSIMAC CE and the first information; wherein the first information includes the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE. Exemplarily, the SL BFR MAC CE can be multiplexed into the SL MAC PDU for transmission. When the SL MAC PDU is packaged, the SCCH data can be placed first, followed by the SLCSIMAC CE, the SL BFR MAC CE, the first information (such as the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE), the SL DRX command MAC CE, the data of any STCH, and finally the data of other lower priorities.

[0208] In some embodiments, the second terminal 102 determines that the logical channel priority of the SL BFR MAC CE sent on the SL resource is sorted between the first information and the SLDRX command MAC CE; wherein the first information includes the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE. Exemplarily, the SL BFR MAC CE can be multiplexed into the SL MAC PDU for transmission. When the SL MAC PDU is packaged, the SCCH data can be placed first, followed by the SLCSIMAC CE, the first information (such as the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE), the SL BFR MAC CE, the SL DRX command MAC CE, the data of any STCH, and finally the data of other lower priorities.

[0209] In some embodiments, the second terminal 102 determines that the logical channel priority of the SL BFR MAC CE sent on the SL resource is ranked between the SL DRX command MAC CE and the data from any sidelink service channel STCH. Exemplarily, the SL BFR MAC CE can be multiplexed into the SL MAC PDU for transmission. When the SL MAC PDU is packaged, the SCCH data can be placed first, followed by the SLCSIMAC CE, the first information (such as the SL terminal internal collaboration IUC request MAC CE and / or the SL IUC information MAC CE), the SL DRX command MAC CE, the SL BFR MAC CE, the data of any STCH, and finally the data of other lower priorities.

[0210] In some embodiments, the value of the logical channel priority of the SL BFR MAC CE sent on the above-mentioned SL resource is a first value. In some embodiments, the first value may be 1, or the first value represents the highest priority. Exemplarily, the value of the logical channel priority of the SL BFR MAC CE sent on the SL resource may be 1. Alternatively, the value of the logical channel priority of the SL BFR MAC CE may also be other values, such as 2, etc., which is not specifically limited in this disclosure.

[0211] In some embodiments, the SL BFR MAC CE sent on the above-mentioned SL resource can be sent by the second terminal 102 to the first terminal 101 in a unicast form, or can be sent in a multicast or broadcast form.

[0212] In some embodiments, the sidelink transmission resource allocation mode of the first terminal is a first resource allocation mode or a second resource allocation mode, wherein the first resource allocation mode is that the network device schedules the sidelink transmission resource; and the second resource allocation mode is that the terminal autonomously selects the sidelink transmission resource.

[0213] In some embodiments, the first terminal may be in any of the following states: RRC connected (RRC CONNECTED) state; RRC idle (RRC IDLE) state; RRC inactive (RRC INACTIVE) state, OOC (out of coverage) state.

[0214] Step S2203 , the second terminal 102 sends SLBFRMACCE to the first terminal 101 .

[0215] Optionally, the first terminal 101 receives a SLBFR MAC CE sent on the SL resource by the second terminal 102. The SL BFR MAC CE can assist the receiving terminal in avoiding selecting the failed beams when the receiving terminal acts as a transmitting terminal.

[0216] In some embodiments, during the LCP process, the second terminal 102 sends the SL BFR MAC CE to the first terminal 101 on the SL resource according to the order of the logical channel priority of the SL BFR MAC CE sent on the SL resource. The SL BFR MAC CE can assist the receiving terminal in avoiding selecting these failed beams when the receiving terminal acts as a transmitting terminal.

[0217] In some embodiments, the second terminal 102 may send the SL BFR MAC CE to the first terminal 101 via unicast.

[0220] It should be noted that, in some embodiments, the above steps S2201 and S2202 can be exchanged in order or performed simultaneously. For example, step S2201 can be performed first and then step S2202. For example, when the second terminal 102 determines that a sidelink beam failure occurs in the PC5 link between the second terminal 102 and the first terminal 101, the second terminal 102 determines the ranking of the logical channel priorities of the SL BFR MAC CE sent on the SL resource. Alternatively, step S2202 can be performed first and then step S2201. For example, after the second terminal 102 determines the ranking of the logical channel priorities of the SL BFR MAC CE sent on the SL resource, the second terminal 102 determines that a sidelink beam failure occurs in the PC5 link between the second terminal 102 and the first terminal 101, then the second terminal 102 sends the above-mentioned SL BFR MAC CE to the first terminal 101. Alternatively, step S2201 and step S2202 can be performed simultaneously. This disclosure is not limited to this.

[0221] Step S2204: The second terminal 102 determines the order of the logical channel priorities of the SLBFRMACCE sent on the air interface Uu resources.

[0224] Exemplarily, the second terminal 102 in the RRC connected state can send the SL BFR MAC CE to the network device 103 to assist the network device 103 in performing SL beam failure recovery. Therefore, the second terminal 102 needs to determine the order of the logical channel priority of the SL BFR MAC CE sent on the Uu resource, so that the second terminal 102 can send the SL BFR MAC CE to the network device 103 on the Uu resource.

[0225] In some embodiments, the SL BFR MAC CE sent by the second terminal 102 on the Uu resource may be a sidelink beam failure recovery MAC CE when the second terminal 102 determines that a sidelink beam failure has occurred on the PC5 link. For example, taking the second terminal 102 as a transmitting terminal, if the transmitting terminal determines that a sidelink beam failure has occurred on the PC5 link, the transmitting terminal sends an SL BFR MAC CE to the network device 103 to assist the network device 103 in performing SL beam failure recovery. Before sending the SL BFR MAC CE to the network device 103, the transmitting terminal needs to determine the order of the logical channel priorities of the SL BFR MAC CE sent on the Uu resource.

[0226] In some embodiments, the second terminal 102 determines that the logical channel priority of the SL BFR MAC CE sent on the air interface Uu resource is ranked between the second information and the Sidelink Configured Grant Confirmation MAC CE.

Exemplarily, the SL BFR MAC CE sent on the Uu resource can be multiplexed into the MAC PDU for transmission. When the MAC PDU is packaged, the third information (such as MAC CE for C-RNTI (MAC CE carrying C-RNTI), or data from UL-CCCH (data of the uplink common control channel)) can be placed first, followed by the above-mentioned second information (such as MAC CE for (Enhanced) BRF (BFRMAC CE), or MAC CE for Configured Grant Confirmation (MAC CE carrying configuration authorization confirmation), or MAC CE for Multiple Entry Configured Grant Confirmation (MAC CE carrying multiple entry configuration authorization confirmation)), SL BFR MAC CE (MAC CE for Sidelink BFR, MAC CE carrying sidelink beam failure recovery), MAC CE for Sidelink Configured Grant Confirmation (MAC CE carrying sidelink configuration authorization confirmation), MAC CE for LBT failure (MAC CE carrying listen-before-talk failure indication), and finally other MAC CEs of lower priority. CE and / or data.

[0228] In some embodiments, the value of the logical channel priority of the SL BFR MAC CE sent on the above-mentioned Uu resource can be a second value. For example, the second value can be 1, or the second value represents the highest priority, or it can also be other values. This disclosure does not make any specific limitations on this.
