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 the embodiments of this disclosure are also applicable to similar technical problems.

[0066] In related technologies, sidelink communication is introduced to support direct communication between terminal devices. Additionally, Packet Data Convergence Protocol (PDCP) multiplexing involves retransmitting a data packet, thus improving transmission reliability and reducing latency, meeting high reliability and low latency requirements. PDCP multiplexing can also be used in sidelink communication; therefore, how to activate sidelink PDCP multiplexing is a problem that urgently needs to be solved.

[0067] In this disclosure, the terminal device can receive first indication information sent by the network device, and activate or deactivate the side link PDCP multiplexing of the side link radio bearer (SLRB) according to the first indication information. The activation method and apparatus for side link PDCP multiplexing provided in this disclosure will be described in detail below with reference to the accompanying drawings.

[0068] Please see Figure 2 , Figure 2 This is a flowchart illustrating an activation method for side-link PDCP multiplexing provided in an embodiment of this disclosure. The method is executed by a first terminal device. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0069] Step 201: Receive the first instruction information sent by the network device.

[0070] The first indication information can be used to activate or deactivate the SLRB side link PDCP multiplexing.

[0071] In this disclosure, the first indication information can be used to indicate the activation or deactivation of the SLRB side link PDCP multiplexing, or the first indication information can be used to indicate the packet quality of service identity (PQI) threshold corresponding to the first terminal device, and the PQI threshold can be used to determine the activation or deactivation of the SLRB side link PDCP multiplexing.

[0072] In this disclosure, PQI can represent multiple different dimensions of service quality requirements, such as requirements for reliability, latency, etc.

[0073] Step 202: Activate or deactivate the SLRB side link PDCP multiplexing according to the first instruction information.

[0074] In this disclosure, if the first indication information is used to indicate the activation or deactivation of the SLRB side-link PDCP multiplexing, then the first terminal device can activate or deactivate the SLRB side-link PDCP multiplexing according to the first indication information. If the first indication information indicates a PQI threshold corresponding to the first terminal device, then the first terminal device can determine whether to activate or deactivate the SLRB side-link PDCP multiplexing according to the PQI threshold.

[0075] In this embodiment of the present disclosure, the first terminal device can receive the first indication information sent by the network device, and activate or deactivate the side link PDCP multiplexing of the SLRB according to the first indication information, thereby realizing the activation or deactivation of the side link PDCP multiplexing.

[0076] See Figure 3 , Figure 3 This is a flowchart illustrating another activation method for side-link PDCP multiplexing provided in an embodiment of this disclosure, the method being executed by a first terminal device. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0077] Step 301: Receive the first configuration information of SLRB sent by the network device via RRC signaling.

[0078] In this disclosure, a network device can send first configuration information of an SLRB to a first terminal device via radio resource control (RRC) signaling. This first configuration information can be used to configure the SLRB. Consequently, the first terminal device can receive the first configuration information of the SLRB sent by the network device via RRC signaling.

[0079] Optionally, the first terminal device may receive the first configuration information of each SLRB sent by the network device.

[0080] In this disclosure, RRC signaling can be dedicated RRC signaling or system information block (SIB) system messages, and this disclosure does not limit it.

[0081] Optionally, the initial configuration information for SLRB can also be pre-configured.

[0082] Step 302: Determine the first indication information according to the value of the preset bit in the first configuration information, wherein the first indication information is used to indicate the activation or deactivation of the SLRB side link PDCP multiplexing.

[0083] In this disclosure, the first configuration information of the SLRB may carry first indication information, wherein the first indication information may be used to indicate the activation or deactivation of the SLRB side link PDCP multiplexing.

[0084] In this disclosure, the value of the preset bit in the first configuration information can be used to represent the first indication information. That is, the value of the preset bit in the first configuration information can be used to indicate the activation or deactivation of the SLRB side link PDCP multiplexing.

[0085] Optionally, in this disclosure, the first indication information can be represented by a single bit. For example, if the value of a single bit is 1, it can indicate that the SLRB side-link PDCP multiplexing is activated; if the bit is omitted, it can indicate that the SLRB side-link PDCP multiplexing is deactivated. That is, if the bit is not set in the first configuration information, it can indicate that the SLRB side-link PDCP multiplexing is deactivated. As another example, if the value of a single bit indicates an enable state, the SLRB side-link PDCP multiplexing can be activated; if the bit is omitted, the SLRB side-link PDCP multiplexing can be deactivated.

[0086] Optionally, in this disclosure, the first indication information can also be represented by the value of two bits. For example, the two bits can indicate 0 and 1. When indicating 1, it can indicate that the SLRB's side-link PDCP multiplexing is activated; when indicating 0, it can indicate that the SLRB's side-link PDCP multiplexing is deactivated. When these two bits are omitted in the first configuration information, it can also indicate that the SLRB's side-link PDCP multiplexing is deactivated. As another example, the two bits can indicate an enable state and a disable state. When the two bits indicate an enable state, the SLRB's side-link PDCP multiplexing is activated; when the two bits indicate a disable state, the SLRB's side-link PDCP multiplexing is deactivated. When these two bits are omitted in the first configuration information, it can also indicate that the SLRB's side-link PDCP multiplexing is deactivated.

[0087] It should be noted that the values ​​of the aforementioned bits and their corresponding indications are merely examples and should not be considered as limitations on this disclosure. Furthermore, the number of bits used to represent the first indication information in the first configuration information can be one, two, or other numbers; this disclosure does not limit this.

[0088] Step 303: Activate or deactivate the SLRB side link PDCP multiplexing according to the first instruction information.

[0089] In this disclosure, if the first indication information is used to indicate the activation of the SLRB side link PDCP multiplexing, then the first terminal device can activate the SLRB side link PDCP multiplexing; if the first indication information is used to indicate the deactivation of the SLRB side link PDCP multiplexing, then the first terminal device can deactivate the SLRB side link PDCP multiplexing.

[0090] In this embodiment of the present disclosure, the first terminal device can receive the first configuration information of the SLRB sent by the network device through RRC signaling, and determine the first indication information according to the value of the preset bit in the first configuration information. The first indication information is used to indicate the activation or deactivation of the SLRB side link PDCP multiplexing. Thus, the first terminal device can activate or deactivate the SLRB side link PDCP multiplexing according to the side link PDCP multiplexing activation or deactivation indication carried in the SLRB configuration information, thereby realizing the activation or deactivation of the side link PDCP multiplexing.

[0091] See Figure 4 , Figure 4 This is a flowchart illustrating another activation method for side-link PDCP multiplexing provided in an embodiment of this disclosure, the method being executed by a first terminal device. Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0092] Step 401: Receive the MAC CE sent by the network device.

[0093] In this disclosure, the network device can send a PDCP multiplexing activation instruction to the first terminal device to activate or deactivate the SLRB via the media access control element (MAC CE), thereby enabling the first terminal device to receive the MAC CE sent by the network device.

[0094] Step 402: Determine the first indication information based on the value of the bit corresponding to SLRB in MAC CE, wherein the first indication information is used to indicate the activation or deactivation of SLRB side link PDCP multiplexing.

[0095] In this disclosure, the MAC CE may carry first indication information, wherein the first indication information is used to indicate the activation or deactivation of the SLRB side link PDCP multiplexing.

[0096] In this disclosure, the value of the bit corresponding to SLRB in MAC CE can be used to represent the first indication information. That is, the value of the bit corresponding to SLRB in MAC CE can be used to indicate the activation or deactivation of SLRB side link PDCP multiplexing.

[0097] Optionally, MAC CE can have n Eight bits are used to indicate the activation or deactivation of the side link PDCP, where n is a positive integer. Each bit corresponds to indicating the activation or deactivation of a side link PDCP multiplexing of an SLRB. The bits of the MAC CE can correspond one-to-one with the ID of the SLRB in ascending or descending order.

[0098] For example, if the value of the bit corresponding to a certain SLRB in MAC CE is 1, it can indicate that the PDCP multiplexing of the side link of that SLRB is activated. If the value of the bit corresponding to that SLRB is 0, it can indicate that the PDCP multiplexing of the side link of that SLRB is deactivated.

[0099] Step 403: Activate or deactivate the SLRB side link PDCP multiplexing according to the first instruction information.

[0100] In this disclosure, if the first indication information is used to indicate the activation of the SLRB side link PDCP multiplexing, then the first terminal device can activate the SLRB side link PDCP multiplexing; if the first indication information is used to indicate the deactivation of the SLRB side link PDCP multiplexing, then the first terminal device can deactivate the SLRB side link PDCP multiplexing.

[0101] In this embodiment of the present disclosure, the first terminal device can receive a MAC CE sent by the network device and determine the first indication information according to the value of the bit corresponding to the SLRB in the MAC CE. The first indication information is used to indicate the activation or deactivation of the SLRB side-link PDCP multiplexing. Thus, the first terminal device can activate or deactivate the SLRB side-link PDCP multiplexing according to the side-link PDCP multiplexing activation or deactivation indication carried in the MAC CE, thereby realizing the activation or deactivation of the side-link PDCP multiplexing.

[0102] See Figure 5 , Figure 5 This is a flowchart illustrating another activation method for side-link PDCP multiplexing provided in an embodiment of this disclosure, the method being executed by a first terminal device. Figure 5 As shown, the method may include, but is not limited to, the following steps:

[0103] Step 501: Send second indication information to the second terminal device, wherein the second indication information is used to instruct the second terminal device to activate or deactivate the SLRB side link PDCP multiplexing.

[0104] In this disclosure, the first terminal device can send a second instruction message to the second terminal device to notify the second terminal device to activate or deactivate the SLRB side link PDCP multiplexing according to the second instruction message.

[0105] Optionally, the first terminal device may receive a first indication message sent by the network device and activate or deactivate the lateral link PDCP multiplexing of the SLRB according to the first indication message. The first terminal device may also send a second indication message to the second terminal device to notify the second terminal device to activate or deactivate the lateral link PDCP multiplexing of the SLRB.

[0106] Optionally, in this disclosure, the second terminal device can be a terminal device that has established a unicast connection with the first terminal device. In this case, the first terminal device can send the second configuration information of the SLRB to the second terminal device through PC5 radio resource control (PC5-RRC) signaling based on the PC5 interface. The values ​​of preset bits in the second configuration information can represent second indication information. Optionally, the PC5-RRC signaling can be RRCReconfigurationSidelink signaling.

[0107] In this disclosure, the value of the preset bit in the second configuration information can represent the explanation of the second indication information. For a detailed description of how the value of the preset bit in the first configuration information can represent the first indication information, please refer to the above description. It will not be repeated here.

[0108] Optionally, in this disclosure, the second terminal device can be a terminal device that has established a unicast connection with the first terminal device. In this case, the first terminal device can also send a sidelink MAC CE to the second terminal device. The sidelink MAC CE carries second indication information, and the value of the bit corresponding to SLRB in the sidelink MAC CE can represent the second indication information.

[0109] In this disclosure, the value of the bit corresponding to SLRB in the sidelink MAC CE can represent the explanation of the second indication information. For a detailed description of how the value of the bit corresponding to SLRB in the MAC CE can represent the first indication information, please refer to the above description. It will not be repeated here.

[0110] Therefore, the first terminal device can send an instruction to activate or deactivate the SLRB sidelink PDCP multiplexing to the second terminal device that has established a unicast connection with the first terminal device via PC5-RRC signaling or sidelink MAC CE.

[0111] Optionally, the second terminal device can also be a terminal device within the same group as the first terminal device, or the second terminal device can also be a terminal device receiving broadcast services. The first terminal device can send a sidelink MAC CE to the second terminal device to notify other terminal devices in the group or terminal devices receiving broadcast services to activate or deactivate the sidelink PDCP multiplexing of the SLRB.

[0112] In this embodiment of the disclosure, the first terminal device may send a second indication message to the second terminal device to notify the second terminal device to activate or deactivate the SLRB side link PDCP multiplexing.

[0113] See Figure 6 , Figure 6 This is a flowchart illustrating another activation method for side-link PDCP multiplexing provided in an embodiment of this disclosure, the method being executed by a first terminal device. Figure 6 As shown, the method may include, but is not limited to, the following steps:

[0114] Step 601: Send a sidelink MAC CE to the second terminal device, wherein the sidelink MAC CE carries second indication information.

[0115] The second indication information can be used to indicate the activation or deactivation of the SLRB side link PDCP multiplexing.

[0116] In this disclosure, the first terminal device can send a sidelink MAC CE to the second terminal device. The sidelink MAC CE carries second indication information to notify the second terminal device to activate or deactivate the sidelink PDCP multiplexing of the SLRB.

[0117] The second terminal device can be a terminal device within the same group as the first terminal device, or it can be a terminal device receiving broadcast services. In other words, the first terminal device can send an instruction to activate or deactivate the side-link PDCP multiplexing to terminal devices within the same group receiving multicast services or to terminal devices receiving broadcast services.

[0118] In this disclosure, the bit corresponding to SLRB in the sidelink MAC CE can represent the second indication information. For a detailed explanation, please refer to the above description of the bit value corresponding to SLRB in the MAC CE representing the first indication information, which will not be repeated here.

[0119] In this embodiment, the second terminal device can be a terminal device within the same group as the first terminal device, or it can be a terminal device receiving broadcast services. The first terminal device can send a sidelink MAC CE to the second terminal device. The sidelink MAC CE carries second indication information, which is used to indicate the activation or deactivation of the sidelink PDCP multiplexing of the SLRB. Therefore, the first terminal device can send an indication to activate or deactivate the sidelink PDCP multiplexing of the SLRB to the terminal devices within the group receiving multicast services or the terminal devices receiving broadcast services via the sidelink MAC CE, thereby notifying the terminal devices within the group receiving multicast services or the terminal devices receiving broadcast services to activate or deactivate the sidelink PDCP multiplexing of the SLRB.

[0120] See Figure 7 , Figure 7 This is a flowchart illustrating another activation method for side-link PDCP multiplexing provided in an embodiment of this disclosure, the method being executed by a first terminal device. Figure 7 As shown, the method may include, but is not limited to, the following steps:

[0124] Step 702: Activate or deactivate the SLRB side link PDCP multiplexing based on the size between the PQI associated with the SLRB and the PQI threshold.

[0125] The PQI associated with SLRB can be configured by the network device or pre-configured; this disclosure does not limit this.

[0126] In this disclosure, the PQI associated with the SLRB can be compared with a PQI threshold. If the PQI associated with the SLRB is greater than or equal to the PQI threshold, the SLRB's side-link PDCP multiplexing can be activated; if the PQI associated with the SLRB is less than the PQI threshold, the SLRB's side-link PDCP multiplexing can be deactivated.
