[0171] In some embodiments, the terminal herein may be an entity on the user side for receiving or transmitting signals, such as a mobile phone.

The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0175] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0176] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0177] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0178] To support direct communication between terminals, a direct link (also called sidelink, SL) communication mode is introduced, and the interface between terminals is PC-5. In some embodiments, three transmission modes are supported on the sidelink based on the corresponding relationship between the sending and receiving terminals: unicast, multicast, and broadcast.

[0179] In some embodiments, sidelink communication has two modes of allocating transmission resources: one is dynamic scheduling by the network (mode 1), and the other is autonomous selection by the terminal from a network-configured or pre-configured resource pool (mode 2). Dynamic scheduling is when the network dynamically allocates transmission resources on the sidelink to the terminal based on the terminal's buffered data report, while autonomous selection is when the terminal randomly selects transmission resources from a network-configured or pre-configured resource pool. The network can configure multiple resource pools for a terminal on a single BWP (Bandwidth Part). The specific allocation method used is configured by the network side through RRC (Radio Resource Control) signaling.

[0180] Carrier aggregation is a key technology in LTE-A. To meet the requirements for single-user peak data rates and improved system capacity, one of the most direct approaches is to increase the system transmission bandwidth. Therefore, LTE-Advanced introduces a bandwidth-enhancing technology called Carrier Aggregation (CA). CA aggregates multiple carriers (also called component carriers, CCs) to effectively increase uplink and downlink transmission rates.

[0181] Packet data convergence protocol duplication (PDCP duplication, also called Packet duplication) is to send a data packet repeatedly. This can repeat the transmission, improve the reliability of data packet transmission, and reduce the delay of repeated transmission to meet the requirements of Ultra Reliable Low Latency Communication (URLLC). In some embodiments, if PDCP multiplexing is not enabled, a PDCP data packet will be transmitted to an RLC (Radio Link Control) entity, which will process it and then send it to the MAC (Medium Access Control) layer, which will complete the data scheduling. In some embodiments, if PDCP multiplexing is enabled, a PDCP packet will be transmitted to two RLC entities, for example, the Primary RLC entity and the Secondary RLC entity in Figure 2. These two RLC entities will process the packet independently and transmit the processed packet to the MAC layer. From the MAC layer's perspective, these are two independent packets. The MAC cannot identify whether these are packets multiplexed by PDCP. The MAC layer only needs to schedule them according to the algorithm.

[0182] It should be noted that in some embodiments, the protocol in the CA scenario requires that the two packets multiplexed by PDCP be transmitted on different cells using different LCHs (logical channels). On the NR Uu interface, the LCH used for PDCP multiplexing is configured by the network device for the terminal through the RB (Radio Bearer) configuration.

[0183] LTE V2X already supports PDCP multiplexing. In LTE V2X, the activation of PDCP multiplexing is achieved through a reliability threshold (such as threshSL-Reliability) configured by the network equipment, and each RB has its own associated PPPR (Per packet reliability) reliability. When the terminal determines that the PPPR reliability associated with an RB is higher than this configured threshold, it activates PDCP multiplexing, and the PDCP entity copies the PDCP PDU (Protocol Data Unit) and delivers it to two RLC entities. This is because LTE V2X does not support SLRB (SL radio bearer) configured by the network equipment. NR sidelink (new air interface sidelink) also supports carrier aggregation. Unlike LTE V2X, NR sidelink supports network equipment to configure SLRB for terminal equipment through dedicated signaling / SIB (system information block) / pre-configuration. In some embodiments, in the NR sidelink CA scenario, PDCP multiplexing can be activated or deactivated through SLRB configuration.

[0184] In some embodiments, a terminal in an RRC connected state may report some measurement reports to a network device, and the network device may activate or deactivate PDCP multiplexing of the SLRB based on the QoS (Quality of Service) attributes of the terminal's SLRB, measurement reports, etc.

[0185] However, for terminals in RRC IDLE / INACTIVE or OOC state, due to the lack of information interaction with network devices, if the activation or deactivation of PDCP multiplexing of SLRB is determined only based on the SLRB configuration in the SIB or pre-configuration by the network device, PDCP multiplexing of some SLRBs may still be activated when the channel conditions are relatively poor.

[0186] To this end, the embodiments of the present disclosure propose a method and apparatus for sidelink data packet convergence protocol PDCP multiplexing, which can activate or deactivate PDCP multiplexing of SLRB based on the measurement results of the terminal and / or the QoS requirements of SLRB, and can realize the activation or deactivation of sidelink PDCP multiplexing. Since the PDCP multiplexing of SLRB is activated or deactivated in combination with the current channel conditions, PDCP multiplexing can be effectively used.

[0187] FIG3A is an interactive diagram illustrating a method for multiplexing a sidelink data packet convergence protocol (PDCP) according to an embodiment of the present disclosure. As shown in FIG3A , the method according to the 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.

[0188] Step S3101: The network device 102 sends measurement configuration information.

[0189] In some embodiments, the network device 102 sends measurement configuration information to the terminal 101. Optionally, the terminal 101 receives the measurement configuration information. Exemplarily, the measurement configuration information may be sent by the network device 102 to the terminal 101. That is, the terminal 101 may receive the measurement configuration information sent by the network device 102.

[0190] In some embodiments, the measurement configuration information is used by terminal 101 to perform measurements so that terminal 101 can activate or deactivate PDCP multiplexing of the SLRB based on the measurement results and / or the QoS requirements of the SLRB. Optionally, activating PDCP multiplexing of the SLRB can also be referred to as using PDCP multiplexing of the SLRB; deactivating PDCP multiplexing of the SLRB can also be referred to as not using PDCP multiplexing of the SLRB.

[0191] In some embodiments, the network device 102 sends second configuration information, which includes the measurement configuration information and / or a preset threshold. The preset threshold is used by the terminal 101 to activate or deactivate PDCP multiplexing of the SLRB. Exemplarily, the network device 102 sends the second configuration information to the terminal 101.

[0192] In some embodiments, the second configuration information may be sent by the network device 102 to the terminal 101 , that is, the terminal 101 may receive the second configuration information sent by the network device 102 .

[0193] In some embodiments, terminal 101 is in any of the following states: RRC IDLE state; RRC INACTIVE state; OOC state. In some embodiments, when terminal 101 is in RRC IDLE / INACTIVE or OOC state, network device 102 may send the measurement configuration information to terminal 101 via SIB / pre-configuration information. Exemplarily, network device 102 may send the second configuration information to terminal 101 via SIB / pre-configuration information, where the second configuration information includes the measurement configuration information, so that terminal 101 can perform measurement according to the measurement configuration information.

[0194] In some embodiments, the transmission resource allocation mode of the terminal 101 may be an autonomously selected allocation mode (ie, the above-mentioned mode 2).

[0195] In some embodiments, the sidelink of terminal 101 adopts carrier aggregation technology.

[0196] Step S3102 : The terminal 101 performs measurement according to the measurement configuration information to determine the measurement result of the carrier aggregated by the terminal 101 .

[0197] In some embodiments, the measurement configuration information may include, but is not limited to, at least one of the following: CBR (Channel Busy Ratio) measurement configuration; RSSI (Received Signal Strength Indication) measurement configuration; RSRP (Reference Signal Receiving Power) measurement configuration; and CO (Channel Occupancy) measurement configuration. Exemplarily, the measurement configuration information may include a CBR measurement configuration. Alternatively, the measurement configuration information may include an RSSI measurement configuration. Alternatively, the measurement configuration information may include an RSRP measurement configuration. Alternatively, the measurement configuration information may include a CO measurement configuration. Alternatively, the measurement configuration information may include both a CBR measurement configuration and an RSSI measurement configuration. Alternatively, the measurement configuration information may include both a CBR measurement configuration and an RSRP measurement configuration. Alternatively, the measurement configuration information may include both a CBR measurement configuration and a CO measurement configuration. Alternatively, the measurement configuration information may include both an RSSI measurement configuration and an RSRP measurement configuration. Alternatively, the measurement configuration information may include both an RSSI measurement configuration and a CO measurement configuration. Alternatively, the measurement configuration information may include both an RSRP measurement configuration and a CO measurement configuration. Alternatively, the measurement configuration information may include a CBR measurement configuration, an RSSI measurement configuration, and an RSRP measurement configuration. Alternatively, the measurement configuration information may include a CBR measurement configuration, an RSRP measurement configuration, and a CO measurement configuration. Alternatively, the measurement configuration information may include an RSSI measurement configuration, an RSRP measurement configuration, and a CO measurement configuration. Alternatively, the measurement configuration information may include a CBR measurement configuration, an RSSI measurement configuration, an RSRP measurement configuration, and a CO measurement configuration.

[0198] In some embodiments, the above-mentioned measurement configuration information includes a CBR measurement configuration. The terminal 101 can perform measurements on the first resource pool of each carrier in the aggregated carriers according to the measurement configuration information to determine the measurement results of the first resource pool on each carrier in the aggregated carriers; the terminal 101 determines the measurement results of the first resource pool on each carrier as the measurement results of each carrier, that is, the terminal 101 can determine the measurement results of each carrier in the carriers aggregated by the terminal 101, that is, the measurement results of the carriers aggregated by the terminal 101 can be determined. Exemplarily, when the above-mentioned measurement configuration information includes a CBR measurement configuration, the terminal 101 can perform measurements on the first resource pool of each carrier in the aggregated carriers according to the CBR measurement configuration to determine the measurement results of the first resource pool on each carrier in the aggregated carriers, and determine the measurement results of the first resource pool on each carrier as the CBR measurement results of the corresponding carrier.

[0199] In some embodiments, the first resource pool of each carrier may be a resource pool selected on the carrier by the terminal 101. The transmission resource allocation mode of the terminal 101 may be an autonomous selection allocation mode (ie, the above-mentioned mode 2).

[0200] Optionally, the one resource pool may be the first selected resource pool. Exemplarily, the first resource pool of each carrier may be the resource pool first selected by terminal 101 on the carrier. For example, taking the carriers aggregated by terminal 101 including carrier 1 and the resource pools selected by terminal 101 on carrier 1 including resource pool 1 and resource pool 2 as an example, the first resource pool of carrier 1 may be the first resource pool selected by terminal 101 on carrier 1, i.e., resource pool 1. Optionally, the one resource pool may be determined based on one or more resource pools selected by terminal 101. That is, the one resource pool may be a resource pool determined by terminal 101 from one or more selected resource pools. For example, taking the carriers aggregated by terminal 101 including carrier 1 and the resource pools selected by terminal 101 on carrier 1 including resource pool 1 and resource pool 2 as an example, the first resource pool of carrier 1 may be a resource pool determined by terminal 101 from resource pool 1 and resource pool 2. For example, the first resource pool of carrier 1 may be resource pool 1, or the first resource pool of carrier 1 may be resource pool 2.

[0201] In some embodiments, the measurement configuration information includes at least one of the following: RSSI measurement configuration, CO measurement configuration, and RSRP measurement configuration. Terminal 101 may perform measurements on each carrier aggregated by terminal 101 based on the measurement configuration information to determine a measurement result for each carrier aggregated by terminal 101. In other words, the measurement result for the carriers aggregated by terminal 101 may be determined. The transmit resource allocation mode of terminal 101 may be an autonomously selected allocation mode (i.e., Mode 2 described above).

[0202] Exemplarily, when the measurement configuration information includes an RSSI measurement configuration, terminal 101 may perform measurement on each carrier among the carriers aggregated by terminal 101 according to the RSSI measurement configuration, and determine an RSSI measurement result for each carrier among the carriers aggregated by terminal 101. Exemplarily, when the measurement configuration information includes a CO measurement configuration, terminal 101 may perform measurement on each carrier among the carriers aggregated by terminal 101 according to the CO measurement configuration, and determine a CO measurement result for each carrier among the carriers aggregated by terminal 101. Exemplarily, when the measurement configuration information includes an RSRP measurement configuration, terminal 101 may perform measurement on each carrier among the carriers aggregated by terminal 101 according to the RSRP measurement configuration, and determine an RSRP measurement result for each carrier among the carriers aggregated by terminal 101. Exemplarily, when the measurement configuration information includes both an RSSI measurement configuration and a CO measurement configuration, terminal 101 may perform measurement on each carrier among the carriers aggregated by terminal 101 according to the RSSI measurement configuration and the CO measurement configuration, and determine a measurement result for each carrier among the carriers aggregated by terminal 101, the measurement result including an RSSI measurement result and a CO measurement result. Exemplarily, when the above-mentioned measurement configuration information includes RSSI measurement configuration and RSRP measurement configuration, terminal 101 can perform measurement on each carrier in the carriers aggregated by terminal 101 according to the RSSI measurement configuration and RSRP measurement configuration, and determine the measurement result of each carrier in the carriers aggregated by terminal 101, where the measurement result includes the RSSI measurement result and the RSRP measurement result. Exemplarily, when the above-mentioned measurement configuration information includes CO measurement configuration and RSRP measurement configuration, terminal 101 can perform measurement on each carrier in the carriers aggregated by terminal 101 according to the CO measurement configuration and RSRP measurement configuration, and determine the measurement result of each carrier in the carriers aggregated by terminal 101, where the measurement result includes the CO measurement result and the RSRP measurement result. Exemplarily, when the above-mentioned measurement configuration information includes RSSI measurement configuration, CO measurement configuration and RSRP measurement configuration, the terminal 101 can perform measurements on each carrier in the carriers aggregated by the terminal 101 according to the RSSI measurement configuration, CO measurement configuration and RSRP measurement configuration, and determine the measurement results of each carrier in the carriers aggregated by the terminal 101, and the measurement results include RSSI measurement results, CO measurement results and RSRP measurement results.

[0203] In step S3103 , the terminal 101 activates or deactivates PDCP multiplexing of the SLRB according to the measurement results of one or more carriers among the carriers aggregated by the terminal 101 and / or the QoS requirements of the SLRB.

[0204] In some embodiments, the terminal 101 may activate or deactivate the PDCP multiplexing of the SLRB based on the measurement results of one or more carriers among the carriers aggregated by the terminal 101. In one possible implementation, the terminal 101 may activate or deactivate the PDCP multiplexing of one or more SLRBs based on the measurement results of one or more carriers among the carriers aggregated by the terminal 101. Optionally, the terminal 101 in the RRC IDLE / INACTIVE / OOC state may activate or deactivate the PDCP multiplexing of the SLRB based on the measurement results of the carriers aggregated by the terminal 101. Exemplarily, the terminal 101 may compare the measurement results of the carriers aggregated by the terminal 101 with a preset threshold (such as a size comparison), and determine whether to activate the PDCP multiplexing of the SLRB or deactivate the PDCP multiplexing of the SLRB based on the comparison result.

[0205] In one possible implementation, the terminal 101 determines that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than or equal to a preset threshold, and the terminal 101 activates the PDCP multiplexing of the SLRB. Alternatively, the terminal 101 determines that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold, and the terminal deactivates the PDCP multiplexing of the SLRB. Exemplarily, if the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than the preset threshold, the terminal 101 determines to activate the PDCP multiplexing of the SLRB; if the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are greater than the preset threshold, the terminal 101 determines to deactivate the PDCP multiplexing of the SLRB; if the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are equal to the preset threshold, the terminal 101 may activate the PDCP multiplexing of the SLRB, or may also deactivate the PDCP multiplexing of the SLRB. As an example, if the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are equal to the preset threshold, the terminal 101 can determine whether to activate the PDCP multiplexing of the SLRB or deactivate the PDCP multiplexing of the SLRB based on the terminal implementation, or, based on the protocol, the terminal 101 determines whether to activate the PDCP multiplexing of the SLRB or deactivate the PDCP multiplexing of the SLRB. The present disclosure does not make specific limitations on this.

[0206] Exemplarily, the preset threshold may be obtained by the terminal 101 through the second configuration information configured by the network device 102. Alternatively, the preset threshold may be predefined by a protocol, or may be obtained based on the implementation of the terminal 101.

[0207] Exemplarily, the number of the above-mentioned one or more carriers may be configured by the network device 102, or may be agreed upon by the protocol, or may be obtained based on the implementation of the terminal 101. For example, assuming that the number of the above-mentioned one or more carriers is represented by M (it may also be represented by other symbols, which is not specifically limited in the present disclosure), the network device 102 configures the value of M for the terminal 101, and the terminal 101 obtains the M through the configuration of the network device 102, where M may be greater than or equal to 1 and less than or equal to the total number of carriers in the carriers aggregated by the terminal 101. When the terminal 101 determines that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, the terminal 101 activates the PDCP multiplexing of the SLRB. If it is determined that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold, the terminal 101 deactivates the PDCP multiplexing of the SLRB.

[0208] In another possible implementation, the terminal 101 determines that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, and the terminal 101 deactivates the PDCP multiplexing of the SLRB. Alternatively, the terminal 101 determines that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold, and the terminal 101 activates the PDCP multiplexing of the SLRB. Exemplarily, if the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are greater than the preset threshold, the terminal 101 determines to activate the PDCP multiplexing of the SLRB; if the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than the preset threshold, the terminal 101 determines to deactivate the PDCP multiplexing of the SLRB; if the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are equal to the preset threshold, the terminal 101 may activate the PDCP multiplexing of the SLRB, or may also deactivate the PDCP multiplexing of the SLRB. As an example, if the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are equal to the preset threshold, the terminal 101 can determine whether to activate the PDCP multiplexing of the SLRB or deactivate the PDCP multiplexing of the SLRB based on the terminal implementation, or, based on the protocol, the terminal 101 determines whether to activate the PDCP multiplexing of the SLRB or deactivate the PDCP multiplexing of the SLRB. The present disclosure does not make specific limitations on this.

[0209] Exemplarily, the preset threshold may be obtained by the terminal 101 through the second configuration information configured by the network device 102. Alternatively, the preset threshold may be predefined by a protocol, or may be obtained based on the implementation of the terminal 101.

[0210] Exemplarily, the number of the above-mentioned one or more carriers may be configured by the network device 102, or may be agreed upon by the protocol, or may be obtained based on the implementation of the terminal 101. For example, assuming that the number of the above-mentioned one or more carriers is represented by M, the network device 102 configures the value of M to the terminal 101, and the terminal 101 obtains M through the configuration of the network device 102, where M may be greater than or equal to 1 and less than or equal to the total number of carriers in the carriers aggregated by the terminal 101. When the terminal 101 determines that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold, the terminal 101 activates the PDCP multiplexing of the SLRB. If it is determined that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, the terminal 101 deactivates the PDCP multiplexing of the SLRB.

[0211] In some embodiments, the terminal 101 may activate or deactivate the PDCP multiplexing of the SLRB based on the QoS requirements of the SLRB. In one possible implementation, the terminal 101 may activate or deactivate the PDCP multiplexing of one or more SLRBs based on the QoS requirements of the one or more SLRBs. Optionally, the terminal 101 in the RRC IDLE / INACTIVE / OOC state may activate or deactivate the PDCP multiplexing of the SLRB based on the QoS requirements of the SLRB. In one possible implementation, the terminal 101 determines that the QoS requirements of the SLRB meet the first condition, and the terminal 101 activates the PDCP multiplexing of the SLRB; or, the terminal 101 determines that the QoS requirements of the SLRB do not meet the first condition, and the terminal 101 deactivates the PDCP multiplexing of the SLRB.

[0212] In some embodiments, the above-mentioned QoS requirements may include at least one of the following parameters: priority, delay, reliability, bit error rate, etc. It should be noted that the above-mentioned QoS requirements contain different contents, and the corresponding first condition will also be different. For example, taking the QoS requirement including the bit error rate as an example, the first condition should be the first condition associated with the bit error rate. For example, when the terminal 101 determines that the bit error rate of the SLRB is less than a threshold, it is considered that the QoS requirement of the SLRB meets the first condition, and the terminal 101 activates the PDCP multiplexing of the SLRB, or the terminal 101 determines that the bit error rate of the SLRB is greater than or equal to the threshold, it is considered that the QoS requirement of the SLRB does not meet the first condition, and the terminal 101 deactivates the PDCP multiplexing of the SLRB. It can be understood that the QoS requirements of the SLRB may also include one or more parameters such as priority, reliability, and delay. The terminal 101 can determine whether the QoS requirements of the SLRB meet the first condition associated with the QoS requirements. If the QoS requirements of the SLRB meet the first condition associated with the QoS requirements, the terminal 101 determines to activate the PDCP multiplexing of the SLRB. If the QoS requirements of the SLRB do not meet the first condition associated with the QoS requirements, the terminal 101 determines to deactivate the PDCP multiplexing of the SLRB.

[0213] In some embodiments, the terminal 101 may activate or deactivate the PDCP multiplexing of the SLRB based on the measurement results of one or more carriers among the carriers aggregated by the terminal 101 and the QoS requirements of the SLRB. In one possible implementation, the terminal 101 may activate or deactivate the PDCP multiplexing of the one or more SLRBs based on the measurement results of one or more carriers among the carriers aggregated by the terminal 101 and the QoS requirements of the one or more SLRBs. Optionally, the terminal 101 in the RRC IDLE / INACTIVE / OOC state may activate or deactivate the PDCP multiplexing of the SLRB based on the measurement results of the carriers aggregated by the terminal 101 and the QoS requirements of the SLRB. Optionally, the terminal 101 may compare the measurement results of the carriers aggregated by the terminal 101 with a preset threshold (such as a size comparison), and determine whether to activate the PDCP multiplexing of the SLRB or deactivate the PDCP multiplexing of the SLRB based on the comparison results and whether the QoS requirements of the SLRB meet the first condition. Exemplarily, the above-mentioned preset threshold may be obtained by the terminal 101 through the second configuration information configured by the network device 102. Alternatively, the preset threshold may be predefined by a protocol, or may be obtained based on the implementation of the terminal 101 .

[0214] In one possible implementation, the terminal 101 determines that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, and the QoS requirement of the SLRB meets the first condition, and the terminal 101 activates the PDCP multiplexing of the SLRB. Alternatively, the terminal 101 determines that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, and the QoS requirement of the SLRB does not meet the first condition, and the terminal 101 deactivates the PDCP multiplexing of the SLRB. Alternatively, the terminal 101 determines that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold, and the QoS requirement of the SLRB meets the first condition, and the terminal 101 deactivates the PDCP multiplexing of the SLRB. Alternatively, the terminal 101 determines that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold, and the QoS requirement of the SLRB does not meet the first condition, and the terminal 101 deactivates the PDCP multiplexing of the SLRB.

[0215] Exemplarily, the number of the one or more carriers may be configured by the network device 102, or may be agreed upon by a protocol, or may be obtained based on the implementation of the terminal 101. For example, assuming that the number of the one or more carriers is represented by M, the network device 102 configures the value of M for the terminal 101, and the terminal 101 obtains M through the configuration of the network device 102, where M may be greater than or equal to 1 and less than or equal to the total number of carriers in the carriers aggregated by the terminal 101. When the terminal 101 determines that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are less than or equal to a preset threshold and the QoS requirements of the SLRB meet the first condition, the terminal 101 activates the PDCP multiplexing of the SLRB. If it is determined that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are less than or equal to the preset threshold and the QoS requirements of the SLRB do not meet the first condition, the terminal 101 deactivates the PDCP multiplexing of the SLRB. If it is determined that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold and the QoS requirements of the SLRB meet the first condition, the terminal 101 deactivates the PDCP multiplexing of the SLRB. If it is determined that the measurement results of M carriers among the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold, and the QoS requirement of the SLRB does not meet the first condition, the terminal 101 deactivates PDCP multiplexing of the SLRB.

[0216] In another implementation, it is determined that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold, and the QoS requirement of the SLRB meets the first condition, and the terminal 101 activates the PDCP multiplexing of the SLRB; or, it is determined that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold, and the QoS requirement of the SLRB does not meet the first condition, and the terminal 101 deactivates the PDCP multiplexing of the SLRB; or, it is determined that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, and the QoS requirement of the SLRB meets the first condition, and the terminal 101 deactivates the PDCP multiplexing of the SLRB; or, it is determined that the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, and the QoS requirement of the SLRB does not meet the first condition, and the terminal 101 deactivates the PDCP multiplexing of the SLRB.

[0217] Exemplarily, the number of the one or more carriers may be configured by the network device 102, or may be agreed upon by a protocol, or may be obtained based on the implementation of the terminal 101. For example, assuming that the number of the one or more carriers is represented by M, the network device 102 configures the value of M for the terminal 101, and the terminal 101 obtains M through the configuration of the network device 102, where M may be greater than or equal to 1 and less than or equal to the total number of carriers in the carriers aggregated by the terminal 101. When the terminal 101 determines that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are greater than or equal to a preset threshold and the QoS requirements of the SLRB meet the first condition, the terminal 101 activates the PDCP multiplexing of the SLRB. If it is determined that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are greater than or equal to the preset threshold and the QoS requirements of the SLRB do not meet the first condition, the terminal 101 deactivates the PDCP multiplexing of the SLRB. If it is determined that the measurement results of the M carriers in the carriers aggregated by the terminal 101 are less than or equal to the preset threshold and the QoS requirements of the SLRB meet the first condition, the terminal 101 deactivates the PDCP multiplexing of the SLRB. If it is determined that the measurement results of the M carriers among the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, and the QoS requirement of the SLRB does not meet the first condition, the terminal 101 deactivates PDCP multiplexing of the SLRB.

[0218] It should be noted that, in some embodiments, when the above-mentioned measurement configuration information includes multiple types of CBR measurement configuration, RSSI measurement configuration, RSRP measurement configuration and CO measurement configuration, the measurement results associated with the measurement configuration information will also include multiple types accordingly. When determining whether the measurement results of the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, it is necessary to determine whether at least one measurement result of each measurement result of the carriers aggregated by the terminal 101 is less than or equal to the corresponding preset threshold. For example, taking the case where the above-mentioned measurement configuration information includes the CBR measurement configuration and the RSSI measurement configuration as an example, the measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than or equal to the preset threshold, including that the CBR measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than or equal to the preset threshold associated with the CBR measurement configuration and / or the RSSI measurement results of one or more carriers among the carriers aggregated by the terminal 101 are less than or equal to the preset threshold associated with the RSSI measurement configuration.

[0407] The present disclosure provides a method for SL PDCP multiplexing that can solve the problem of activating or deactivating PDCP multiplexing of SLRBs in a terminal in RRC IDLE / INACTIVE / OOC state. In some embodiments, a terminal in RRC IDLE / INACTIVE / OOC can activate PDCP multiplexing of SLRBs based on CBR measurement results.

[0408] In one possible implementation, a terminal in RRC IDLE / INACTIVE / OOC determines whether to activate PDCP multiplexing of SLRB based on the CBR measurement result. Exemplarily, the terminal operates in the above-mentioned mode2. Exemplarily, the terminal obtains the CBR of the carrier, and the CBR of the carrier can be the CBR of the resource pool on the carrier. For example, the measured CBR of the first resource pool selected on the carrier is the CBR of the carrier. Exemplarily, if the CBRs of the carriers aggregated by the terminal are all less than or equal to the preset threshold, the terminal activates PDCP multiplexing of SLRB. Exemplarily, if the CBRs of M carriers in the carriers aggregated by the terminal are less than or equal to the preset threshold, the terminal activates PDCP multiplexing of SLRB. M is a multiple of the total number of carriers in the aggregated carriers, 0 <M<1。

[0409] In one possible implementation, the terminal may determine whether to activate PDCP multiplexing in combination with the PDCP multiplexing indication in the SLRB configuration (such as the first configuration information of the SLRB mentioned above). Exemplarily, the terminal obtains the SLRB configuration through SIB or pre-configuration. Exemplarily, if the PDCP multiplexing indication in the SLRB configuration activates the PDCP multiplexing of the SLRB, and the CBRs of the carriers aggregated by the terminal are all less than or equal to the preset threshold (or M of the carriers aggregated by the terminal are less than or equal to the preset threshold), the terminal activates the PDCP multiplexing of these SLRBs.

[0410] In some embodiments, a terminal in RRC IDLE / INACTIVE / OOC may deactivate PDCP multiplexing of SLRB based on CBR measurement results. In one possible implementation, a terminal in RRC IDLE / INACTIVE / OOC determines whether to deactivate PDCP multiplexing of SLRB based on CBR measurement results. Exemplarily, the terminal obtains the CBR of the carrier, and the CBR of the carrier may be the CBR of the resource pool on the carrier. For example, the measured CBR of the first resource pool selected on the carrier is the CBR of the carrier. Exemplarily, if the CBRs of the carriers aggregated by the terminal are all greater than or equal to the preset threshold, the terminal deactivates PDCP multiplexing of SLRB. Exemplarily, if the CBRs of M carriers among the carriers aggregated by the terminal are greater than or equal to the preset threshold, the terminal deactivates PDCP multiplexing of SLRB. M is a multiple of the total number of carriers in the aggregated carriers, 0 <M<1。

[0411] In one possible implementation, the terminal may determine whether to deactivate PDCP multiplexing in combination with the PDCP multiplexing indication in the SLRB configuration (such as the first configuration information of the SLRB mentioned above). Exemplarily, the terminal obtains the SLRB configuration through SIB or pre-configuration. Exemplarily, if the PDCP multiplexing indication in the SLRB configuration activates the PDCP multiplexing of the SLRB, and the CBRs of the carriers aggregated by the terminal are all greater than or equal to the preset threshold (or M of the carriers aggregated by the terminal are greater than or equal to the preset threshold), the terminal deactivates the PDCP multiplexing of these SLRBs.

[0412] In some embodiments, a terminal in an RRC connected state determines whether to activate PDCP multiplexing of the SLRB based on the PDCP multiplexing indication in the SLRB configuration. In one possible implementation, a terminal in an RRC connected state, a terminal working in the above-mentioned mode 1 and / or the above-mentioned mode 2, determines whether to activate PDCP multiplexing of the SLRB based on the PDCP multiplexing indication in the SLRB configuration. If the SLRB configuration indicates that the SLRB activates PDCP multiplexing, the terminal activates PDCP multiplexing for the SLRB; if the SLRB configuration indicates that the SLRB deactivates PDCP multiplexing, the terminal deactivates PDCP multiplexing for the SLRB. Exemplarily, the terminal can obtain the SLRB configuration through dedicated signaling.

[0413] In some embodiments, the network side carries the SLRB PDCP multiplexing activation / deactivation indication through MAC CE. In one possible implementation, the MAC CE may have n*8 bits, where the value range of n is 1 to 64. Exemplarily, each bit corresponds to the SL PDCP multiplexing activation / deactivation status of an SLRB, 1 indicates that the corresponding SLRB activates SL PDCP multiplexing, and 0 indicates that the corresponding SLRB deactivates SL PDPC duplication. Exemplarily, each bit corresponds to the configuration index configuration index in the SLRB configuration list, for example: the activation / deactivation indication information of the SLRB corresponding to SLRB-Uu-ConfigIndex.
