Referring to FIG. 1 , in a scenario where direct communication is performed between direct communication devices, the network device configures various transmission parameters for data transmission for the direct communication device 1 . The direct communication device 1, the direct communication device 2 and the direct communication device 3 perform direct communication. There may be obstacles between the direct communication device 2 and the direct communication device 3 . The link for communication between the network device and the direct communication device is an uplink and downlink, and the link between the direct communication device and the direct communication device is a direct link (Sidelink).

In the present disclosure, the communication scenario of direct communication between directly connected communication devices may be a vehicle wireless communication technology (Vehicle to Everything, V2X) business scenario. Among them, V represents the on-board device, and X represents any object that interacts with the on-board device. Currently X mainly includes in-vehicle devices, handheld devices, traffic roadside infrastructure and networks. The information mode of V2X interaction includes: between vehicle equipment and vehicle equipment (Vehicle to Vehicle, V2V), between vehicle equipment and roadside equipment (Vehicle to Infrastructure, V2I), between vehicle equipment and handheld equipment (Vehicle to Pedestrian, V2P), the interaction between vehicle equipment and network (Vehicle to Network, V2N).

With the development of the new generation of 5G mobile communication technology, 5G NR technology is used in 3GPP Rel-16 to support new V2x communication services and scenarios, such as Vehicles Platooning, Extended Sensors, advanced Driving (Advanced Driving), and remote driving (remote driving), etc. Generally speaking, 5G V2x sidelink can provide higher communication rate, shorter communication delay, and more reliable communication quality.

The communication scenario of direct communication between directly connected communication devices may also be a device-to-device (Device to Device, D2D) communication scenario. The direct communication devices for direct communication in the embodiments of the present disclosure may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user Equipment (User Equipment, UE), mobile station (Mobile station, MS), terminal (terminal), terminal equipment (Terminal Equipment) and so on. For convenience of description, the embodiments of the present disclosure are described below by taking a directly connected communication device as a user equipment as an example.

Among them, the enhancement of NR Sidelink can improve transmission reliability and reduce delay. In the enhancement of NR Sidelink, in terms of enhancing Mode2 resource allocation, the 3GPP working group reached a conclusion that it is necessary to study a method for assisting resource selection among user equipment.

For the non-preferred auxiliary resource set type of user equipment B, user equipment B makes a difference set between the perceived resource set and the non-preferred auxiliary resource set type of user equipment B, that is, user equipment B excludes user equipment B's non-preferred resource set from the perceived resource set Auxiliary resource set type to determine the resource set required for data transfer.

In an example, taking the first user equipment as UEA and the second user equipment as UEB as an example, the method for performing communication based on the auxiliary resource set provided by the embodiment of the present disclosure is exemplarily described.

Example 1: The UEA provides a corresponding type of resource set according to the type of the auxiliary resource set pre-configured in the sending resource pool where the UEA is located. The UEB knows the resource set type configured in its sending resource pool, and performs corresponding resource selection behavior.

For example, the TX resource pool of UE A and the TX resource pool of UE B are in the same resource pool. For example, the serial number of the TX pool is 1, and the resource pool with the serial number is 1, and the auxiliary resource set configured is the preferred resource set. UEA provides the preferred resource set to UEB, and UEB also knows that it receives the preferred resource set, and the resource set perceived by UEB is intersected with the preferred resource set. If it is a non-preferred resource set, the resource set perceived by UEB and the non- The preferred resource set is a difference set, that is, the UEB excludes the non-preferred resource set from the resource set it perceives.

Example 2: UEA needs to obtain the configuration information of UEB's transmission resource pool, and provide auxiliary resource sets according to the preconfigured resource set type of UEB's transmission resource pool; UEB executes the corresponding resource set type according to the resource set type configured in its own transmission resource pool. Choose behavior.

Wherein, the UEB carries the configuration information of the transmission resource pool of the UEB (including the type of the auxiliary resource set) and/or the configuration information of the type of the auxiliary resource set of the transmission resource pool of the UEB in the assistance request. Or through high-level signaling, after the UEA and the UEB exchange signaling, the UEA acquires the resource pool where the UEB is located and the configuration information of the auxiliary resource set type of the resource pool.

For example, the sending resource pool of the UEA and the sending resource pool of the UEB are in different resource pools. For example, the sequence number of the sending resource pool of UEA is 1, and the sequence number of the sending resource pool of UEB is 2. UEA acquires the auxiliary resource set type configuration information of UEB's transmission resource pool as non-preferred resource set, and UEA provides non-preferred resource set to UEB. UEB also knows that it has received a non-preferred resource set, and UEB will intersect the perceived resource set with the preferred resource set.
