[0057] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0058] Figure 1 is a schematic diagram of a communication system applicable to embodiments of the present application. Transmission resources for vehicle-mounted terminals (vehicle-mounted terminal 121 and vehicle-mounted terminal 122) are allocated by base station 110. The vehicle-mounted terminals transmit data on the sidelink based on the resources allocated by base station 110. Specifically, base station 110 can allocate resources for a single transmission to a terminal, or it can allocate resources for semi-static transmission to the terminal.

[0059] Figure 2 is a schematic diagram of another communication system applicable to an embodiment of the present application. Vehicle-mounted terminals (vehicle-mounted terminal 131 and vehicle-mounted terminal 132) autonomously select transmission resources on the sidelink for data transmission. Alternatively, the vehicle-mounted terminals can select transmission resources randomly or through interception.

[0060] It should be noted that device-to-device communication is a sidelink (SL) transmission technology based on D2D. Unlike traditional cellular systems, where communication data is received or sent via base stations, this technology offers higher spectrum efficiency and lower transmission latency. The connected vehicle system utilizes direct end-to-end communication. 3GPP defines two transmission modes: Mode 1 (sidelink resource allocation mode 1) and Mode 2 (sidelink resource allocation mode 2).

[0061] Mode 1: The base station allocates transmission resources to the terminal, and the terminal transmits data on the sidelink based on the allocated resources. The base station can allocate resources for single transmissions or semi-static transmissions. When the terminal is within network coverage, the network allocates transmission resources for sidelink transmissions.

[0062] Second mode: The terminal selects a resource from the resource pool for data transmission. If the terminal is outside the cell coverage area, the terminal autonomously selects a transmission resource from the pre-configured resource pool for sideline transmission; or the terminal autonomously selects a transmission resource from the network-configured resource pool for sideline transmission.

[0063] New Radio-Vehicle to Everything (NR-V2X) supports autonomous driving, placing higher demands on data exchange between vehicles, such as higher throughput, lower latency, greater reliability, wider coverage, and more flexible resource allocation. NR-V2X supports unicast, multicast, and broadcast transmission modes.

[0064] In the second mode, the terminal decodes sidelink control information and measures the sidelink received power, then selects resources from the resource pool that are not reserved by other terminals, or that are reserved by other terminals but have lower received power. This reduces the probability of resource collisions and improves communication reliability. The second mode generally inherits the main design of the resource selection mechanism in LTE-V2X Mode 4, and performs resource selection based on resource reservation, resource listening, and resource exclusion.

[0065] For inter-UE coordinated resource selection, one terminal (UE-A) provides resource coordination information to another terminal (UE-B) performing the second mode of resource selection. UE-B then selects the final transmission resource based on its own resource sensing results and the received resource coordination information, or based solely on the resource coordination information, as shown in Figure 3. For example, the transmitter selects the final transmission resource based on Quality of Service (QoS) information (such as logical channel (LCH) priority and packet delay budget (PDB)) and the resource transmission set recommended by the receiver, for sidelink (SL) transmission between terminals (UE-UE), transmission between terminals and relays (UE-relay), transmission between terminals and relays (UE-Relay-UE), or transmission between relays (Relay-Relay).

[0066] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0067] 5G needs to support real-time QoS parameters, including round-trip time (RTT). RTT is the transmission delay between two endpoints. How to support bidirectional QoS requirements, namely RTT requirements, on the SL is a problem that needs to be solved.

[0068] Based on the above problems, this application proposes a side communication solution. In the case of bidirectional QoS requirements, the sender and / or receiver can perform relevant operations based on the bidirectional QoS requirement information, thereby improving the side communication quality.

[0069] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0070] FIG4 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG4 , the wireless communication method 200 may include at least part of the following contents:

[0071] S210, the receiving end performs a first operation based on the bidirectional QoS requirement information on the side link; wherein the first operation includes at least one of the following: determining the PDB of the reverse link, adjusting the PDB of the reverse link, determining the PDU set delay budget (PSDB) of the reverse link, adjusting the PSDB of the reverse link, determining the remaining delay, determining the remaining delay of the reverse link, deleting packets, recommending the forward link PSDB, recommending the forward link PDB, adjusting the selected resources, adjusting the selected resource set, selecting transmission resources, selecting a transmission resource set, recommending optional resources for the sending end, recommending an optional resource set for the sending end, triggering feedback, performing feedback, obtaining or determining time information, obtaining or determining delay information, obtaining or determining auxiliary information.

[0072] It should be understood that FIG4 shows the steps or operations of the wireless communication method 200, but these steps or operations are merely examples, and the embodiments of the present application may also perform other operations or variations of the operations in FIG4.

[0073] In the embodiment of the present application, in the case of a bidirectional QoS requirement, the receiving end may perform the first operation according to the bidirectional QoS requirement information, thereby ensuring the bidirectional QoS requirement and improving the side communication quality.

[0074] In the embodiments of the present application, the receiving end may also be referred to as a receiving end device, and the transmitting end may also be referred to as a transmitting end device. Optionally, the receiving end may be a terminal device, a receiving end terminal, or a relay, and the transmitting end may be a terminal device, a transmitting end terminal, or a relay. Optionally, the receiving end and the transmitting end communicate directly via a sidelink, or the receiving end and the transmitting end communicate via a relay link.

[0075] In the embodiment of the present application, the link from the transmitting end to the receiving end is a forward link, and the link from the receiving end to the transmitting end is a reverse link, as shown in FIG5 .

[0076] In an embodiment of the present application, the bidirectional QoS requirement, and the counterpart or counterparts to which it is directed, may be explicitly indicated (for example, both parties pre-configured by the application layer or the network, or a group pre-configured by the application layer or the network, or the interaction between the sending end and the receiving end, or the counterpart or counterparts configured to perform the first operation), or may be implicitly determined (for example, whether the configured QoS parameters include bi-directional QoS parameters, or whether bi-directional QoS is enabled, or the counterpart or counterparts that send and / or receive the bidirectional QoS requirement, or the counterpart or counterparts that perform the first operation).

[0077] In some embodiments, the bidirectional QoS requirement information is dynamic or semi-static.

[0078] For example, the first operation includes determining / adjusting the PDB of the reverse link. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the PDB of the reverse link according to the bidirectional QoS requirement information.

[0079] For example, the first operation includes determining / adjusting the PSDB of the reverse link. Thus, in the case of bi-directional QoS requirements, the receiving end can determine / adjust the PSDB of the reverse link according to the bi-directional QoS requirement information.

[0080] For example, the first operation includes determining / adjusting the reverse link PDB and determining / adjusting the reverse link PSDB. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the reverse link PDB and determine / adjust the reverse link PSDB based on the bidirectional QoS requirement information.

[0081] For example, the first operation includes determining / adjusting the reverse link PDB and determining the residual delay. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the reverse link PDB and determine the residual delay based on the bidirectional QoS requirement information, thereby enabling the receiving end to perform more reasonable transmission on the reverse link.

[0082] For example, the first operation includes determining / adjusting the reverse link PDB and adjusting the selected resources and / or resource sets. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the reverse link PDB and adjust the selected resources and / or resource sets based on the bidirectional QoS requirement information, thereby enabling the receiving end to perform more reasonable transmission on the reverse link.

[0083] For example, the first operation includes determining / adjusting the reverse link PDB and selecting transmission resources and / or resource sets. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the reverse link PDB and select transmission resources and / or resource sets based on the bidirectional QoS requirement information, thereby enabling the receiving end to perform more reasonable transmission on the reverse link.

[0084] For example, the first operation includes recommending resources and / or resource sets that are optional to the transmitter. Thus, in the case of bidirectional QoS requirements, the receiver can recommend resources and / or resource sets that are optional to the transmitter based on the bidirectional QoS requirement information, so that the transmitter can perform more reasonable transmission on the forward link.

[0085] For example, the first operation includes recommending resources and / or resource sets that the sender can select and performing feedback. Thus, in the case of bidirectional QoS requirements, the receiver can recommend resources and / or resource sets that the sender can select based on the bidirectional QoS requirement information and perform feedback, so that the sender can perform more reasonable transmission on the forward link.

[0086] For example, the first operation includes determining / adjusting the reverse link PDB, determining the remaining delay, or determining the remaining delay of the reverse link. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the reverse link PDB, determine the remaining delay, or determine the remaining delay of the reverse link based on the bidirectional QoS requirement information, thereby enabling the receiving end to perform more reasonable transmission on the reverse link.

[0087] For example, the first operation includes determining / adjusting the reverse link PDB and packet deletion. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the reverse link PDB and packet deletion based on the bidirectional QoS requirement information, thereby enabling the receiving end to perform more reasonable transmission on the reverse link.

[0088] For example, the first operation includes determining / adjusting the reverse link PDB, determining the remaining delay or determining the remaining delay of the reverse link, and adjusting the selected resources and / or resource sets. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the reverse link PDB, determine the remaining delay or determine the remaining delay of the reverse link, and adjust the selected resources and / or resource sets based on the bidirectional QoS requirement information, thereby enabling the receiving end to perform more reasonable transmission on the reverse link.

[0089] For example, the first operation includes determining / adjusting the reverse link PDB, determining the remaining delay or determining the remaining delay of the reverse link, adjusting the selected resources and / or resource sets, and deleting packets. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the reverse link PDB, determine the remaining delay or determining the remaining delay of the reverse link, adjust the selected resources and / or resource sets, and delete packets based on the bidirectional QoS requirement information, thereby enabling the receiving end to perform more reasonable transmission on the reverse link.

[0090] In some embodiments, when the first operation includes adjusting the PDB of the reverse link, the receiving end may adjust the PDB of the reverse link based on preset PDB parameters, or the receiving end may adjust the PDB of the reverse link based on PDB parameters determined by negotiation between the receiving end and the transmitting end, or the receiving end may independently decide how to adjust the PDB of the reverse link.

[0091] In some embodiments, when the first operation includes adjusting the PSDB of the reverse link, the receiving end may adjust the PSDB of the reverse link based on preset PSDB parameters, or the receiving end may adjust the PSDB of the reverse link based on PSDB parameters determined by negotiation between the receiving end and the transmitting end, or the receiving end may independently decide how to adjust the PSDB of the reverse link.

[0092] In some embodiments, when the first operation includes recommending a forward link PSDB, the receiving end may recommend the forward link PSDB based on preset PSDB parameters, or the receiving end may recommend the forward link PSDB based on PSDB parameters determined by negotiation between the receiving end and the transmitting end, or the receiving end may independently decide how to recommend the forward link PSDB.

[0093] In some embodiments, when the first operation includes recommending a forward link PDB, the receiving end may recommend the PDB of the forward link based on preset PDB parameters, or the receiving end may recommend the PDB of the forward link based on PDB parameters determined by negotiation between the receiving end and the transmitting end, or the receiving end may independently decide how to recommend the PDB of the forward link.

[0094] In some embodiments, both the reverse link PSDB and the reverse link PDB may be determined / adjusted, or only the reverse link PSDB may be determined / adjusted, or only the reverse link PDB may be determined / adjusted.

[0095] In some embodiments, if a PSDB exists or is indicated to be determined, only the PSDB of the reverse link is determined / adjusted, or the PSDB of the reverse link is determined / adjusted, or the PDB of the reverse link is not determined / adjusted.

[0096] In some embodiments, if a PDB exists or is indicated to be determined, only the PDB of the reverse link is determined / adjusted, or the PDB of the reverse link is determined / adjusted, or the PSDB of the reverse link is not determined / adjusted.

[0097] In some embodiments, if the PSDB does not exist, or an indication is given that the PSDB is uncertain, only the PDB of the reverse link is determined / adjusted, or the PDB of the reverse link is determined / adjusted, or the PSDB of the reverse link is not determined / adjusted.

[0098] In some embodiments, when the first operation includes packet deletion, the receiving end may delete data packets or data to be transmitted or buffered. The data or data packets to be transmitted or buffered may be data or data packets transmitted via a reverse link, or data or data packets transmitted to a higher layer (e.g., a non-access stratum (NAS) or an application layer).

[0099] In some embodiments, when the first operation includes packet deletion, the receiving end may request the transmitting end or the peer end to send packet deletion auxiliary information. The packet deletion auxiliary information is used by the receiving end to perform the packet deletion operation. The auxiliary information includes but is not limited to a sequence number.

[0100] In some embodiments, when the first operation includes packet deletion, the receiving end may send packet deletion information to the sending end or the peer end. The packet deletion information is used to indicate the packet information deleted by the receiving end. The packet deletion information includes but is not limited to a sequence number.

[0101] In some embodiments, where the first operation includes determining the residual delay, the receiving end may determine the residual delay of the reverse link and / or the forward link.

[0102] For example, the first operation includes determining the residual delay. Thus, in the case of bidirectional QoS requirements, the receiving end can determine / adjust the PDB of the reverse link and / or forward link based on the bidirectional QoS requirement information, thereby enabling the receiving end to perform more appropriate transmission on the reverse link and / or the transmitting end to perform more appropriate transmission on the forward link.
