- Sidelink was first introduced in the LTE system and is mainly used in D2D (Device to Device Communication) technology. The main purpose is to ensure the effective communication of public safety information (Public Safety Communication). Later, the concept of V2X (Vehicle to Everything, Internet of Vehicles) was introduced into the LTE system, and Sidelink was also part of the V2X standardization. Sidelink is defined as a communication mode that realizes direct communication of short-range services between terminal devices through the PC5 interface. In the latest version of 3GPP (3rd Generation Partnership Project), Sidelink resource allocation based on air interface assistance and PC5 interface management is regarded as the focus of the next research, which helps to meet the requirements of V2X in NR systems. The requirements for communication performance such as delay and reliability are of great significance to the communication scenarios in which users who can only conduct V2X communication through Sidelink independently select the resource mode.

- FIG. 2 The communication process of Sidelink is shown in Figure 2, which is divided into two parts: synchronization and communication.
- the synchronization process in order to make all terminal devices enter the synchronization state, there are currently two types of Sidelink synchronization processes: the synchronization process based on GNSS (Global Navigation Satellite System, Global Navigation Satellite System) and the synchronization process based on base stations.
- the allocation of resources is divided into two ways.
- Figure 3A shows the resource allocation method based on the base station. In this resource allocation method, there is a control link between the base station and the terminal device;
- Figure 3B shows the terminal's autonomous selection. In this resource allocation method, there is no control link between the base station and the terminal device.
- Figure 3C shows the specific process of the resource allocation method based on the base station.
- the terminal 1 needs to send data, it sends a resource request to the base station.
- the resource is sent to Terminal 1.
- terminal 1 After receiving the DCI message, terminal 1 sends data to terminal 2 using the resources indicated in the DCI message. It can be seen from the above process that in the base station-based resource allocation method, the sidelink resources of the terminal need to be centrally allocated by the base station, so the resource allocation method shown in FIG. 3C generally does not cause resource conflicts.
- Figure 3D shows the specific process of the terminal autonomously selecting the resource allocation method.
- terminal 1 When terminal 1 needs to send data, terminal 1 first performs resource sensing (Resource Sensing). Specifically, terminal 1 measures all resources in the resource pool. Then select a set of resources from the resource pool to send data.
- the configuration of the resource pool is divided into two scenarios. One is that the terminal is within the coverage of the base station network, and the configuration of the resource pool can be obtained from the system messages of the base station; the other is that the terminal is not within the coverage of the base station network, and the configuration of the resource pool is preconfigured. It can be seen from the above process that in the resource allocation method independently selected by the terminal, the terminal selects resources completely autonomously. Therefore, the resource allocation method shown in FIG.
- the resource allocation method independently selected by the terminal is also applicable to scenarios where the terminal is not within the coverage of the base station network, or the base station network coverage is poor.

- the mechanism that operates in units of groups has become the main research object, and groups are also called communication groups.
- the operating mechanism in groups has many advantages. Specifically, in a heavy load scenario, if all user equipments compete for resources autonomously, the probability of resource conflict and collision is very high. If there is a group head to coordinate the allocation of resources, the probability of resource conflict and collision can be greatly reduced. Resources are negotiated at a large granularity between groups, and group heads within a group uniformly allocate resources, which can improve the efficiency of resource use. In addition, since the information interaction with the base station is reduced, the delay of the air interface can be reduced.

- the embodiments of the present application mainly relate to the problem of resource competition between groups in the Sidelink technology.
- the resources of each group can compete for resources in a group, or compete independently for each terminal device.
- the resources between groups can be orthogonal to each other or partially overlap. Resources between groups need to be competed for the entire group by the group head.
- selecting overlapping resources will cause greater signal interference on the overlapping resources. Therefore, two group heads that are close in distance will avoid selecting overlapping resources to improve the probability of successful signal demodulation.
- two group heads that are far apart will try to select overlapping resources to improve resource utilization. Therefore, the positions of the group heads are different, which will lead to a large difference in the resource results obtained by competition, and some resources are not necessarily suitable for the group members in the group.
- Group A there are three groups in the figure, namely Group A, Group B-1 and Group B-2.
- the group header in Group B-1 is far away from Group A, so when the group header in Group B-1 competes for resources, it may think that Group A has little interference with Group B-1, so it chooses to intersect with Group A. overlapping or completely overlapping resources.
- the group members in the lower left corner of Group B-1 are very close to Group A. If resources completely overlapping with Group A are used, serious interference will occur, resulting in poor performance of these user equipments.
- the group head in Group B-2 is closer to Group A, so when the group head in Group B-2 competes for resources, it may think that Group A interferes greatly with Group B-2, so it may choose to be completely the same as Group A. Staggered resources.
- the group members in the lower right corner of Group B-2 are far away from Group A, so they can use resources that overlap with Group A, which will result in low resource utilization.
