Technical field

The present disclosure relates to the field of communication technology, and in particular, to a direct link configuration method, device, terminal and network equipment.

Background technique

In the 5G New Radio (NR) (new wireless access technology) vehicle wireless communication technology (vehicle to Direct communication. Before business data transmission, it is first necessary to determine the time-frequency resources used for direct link data transmission. The main criterion for determining time-frequency resources is to avoid collisions between time-frequency resources used by different terminals to avoid mutual interference. . In NR V2X, there are two resource scheduling modes. The first is Mode 1 resource allocation mode. The base station uniformly schedules the time and frequency resources used by each terminal in direct link communication. The second is Mode 2 resources. In the allocation mode, the terminal independently selects the time-frequency resources used in direct link communication without the participation of the base station.

Among them, 5G NR-V2X Mode 2 uses distributed resource scheduling. Since there is no unified scheduling by the base station, the terminal (UE) needs to determine the resource occupancy of other UEs through the resource sensing mechanism, and select resources based on the resource sensing results. Compared with a completely random resource selection mechanism, the resource awareness mechanism can improve resource utilization, reduce collision probability, and improve system performance.

Specifically, in the related technology, in the distributed resource scheduling mode, the terminal will exclude resources based on the results of its own resource sensing, that is, it will eliminate the conflicting resources it perceives. However, in current network deployment, 4G terminals and 5G terminals will exist at the same time. In this way, when there is direct link communication between 4G terminals and 4G terminals, and there is also direct link communication between 5G terminals and 5G terminals, due to These two direct link communications belong to different communication standards, so they cannot sense each other, and the resources occupied by the 4G direct link and the 5G direct link will collide, causing mutual interference. The problem.

From the above, the related technology cannot support the problem of collision avoidance of scheduling resources of different communication standards.

The content involved in the solution provided by the embodiment of the present disclosure is first introduced below.

The steps for 5G NR-V2X direct link Mode2 resource allocation include the following:

(1) Resource awareness: Resource awareness means that the terminal determines whether the resource is used by other terminals based on the RSRP (Reference Signal Received Power) strength of the signal received on a resource. In the resource sensing process, it is necessary to consider the different characteristics of periodic services and non-periodic services in mixed service scenarios in NR V2X applications, as well as the impact of service types on resource sensing results. At the same time, appropriate resource-aware configuration needs to be performed based on the time-frequency resource granularity in the physical channel, resource pool settings and other information. The resource sensing window refers to the time window for the terminal to sense resources.

(2) Resource exclusion: The main purpose of resource exclusion is to exclude resources that are not available for resource selection within the resource selection window based on the sensing results, such as excluding the time-frequency resources required by the terminal to receive data (NR V2X terminal uses half-duplex (half-duplex means that the terminal cannot send and receive data at the same time), forming a candidate resource set, reducing the probability of resource collision and improving reliability.

(3) Resource selection: The resource selection mechanism is to select the appropriate transmission time and frequency resources for the business packet TB (transmission block) to be sent in the candidate resource set. It needs to consider the priority, delay, business packet size, and transmission reliability of the business. Sexuality requires resource selection. The resource selection window refers to the time window for the terminal to select resources.

Among them, 5G NR-V2X Mode 2 adopts a distributed resource scheduling mechanism. Since there is no unified scheduling by the base station, the UE needs to determine the resource occupancy of other UEs through the resource sensing mechanism, and make resource selections based on the resource sensing results. Compared with a completely random resource selection mechanism, the resource awareness mechanism can improve resource utilization, reduce collision probability, and improve system performance. 4G LTE Mode4 also uses the distributed resource scheduling mechanism mentioned above.

When the service arrives, the terminal receives the data packet within the resource awareness window and decodes the SCI (cut-through link control information). The resources that fall within the resource selection window and have RSRP greater than the RSRP threshold need to be excluded. The remaining resources are candidate resources. Then the resources required for direct link transmission are randomly selected from 20% of the candidate resources with the smallest RSSI (received signal strength indication) or directly from all candidate resources. The length of the resource selection window can be configured as the maximum period of the service.

Before sending data on the direct link, the terminal first performs resource sensing and selects resources based on the results of resource sensing. This mechanism can avoid collisions to a certain extent. As shown in Figure 2, when the terminal selects resources, it will exclude perceived conflicting resources.

Based on the above, embodiments of the present disclosure provide a direct link configuration method, device, terminal and network equipment to solve the problem in related technologies of being unable to support scheduling resources of different communication formats to avoid collisions.

Example 1 (base station, terminal B or terminal C sends indication information);

This example involves the following:

Terminal A and terminal B (pre)configure the resource pool or SL DRX according to the instruction information.
