Abstract

The invention provides a resource selection method and device and terminal equipment. The method relates to the technical field of communication, is applied to coordinated UE of a V2X straight-throughlink system, and comprises the following steps: sending straight-through link resource coordination request information; receiving straight-through link resource coordination information for coordinating the UE; and performing resource selection of the straight-through link according to the straight-through link resource coordination information. According to the invention, the problem that the direct link resource coordination information overhead is too large due to imperfect direct link resource coordination request information can be solved; the timeliness of the straight-through link resource coordination information is poor; and the bearing mode of the straight-through link resource coordination request information is uncertain due to the uncertain overhead of the straight-through link resource coordination request information.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a resource selection method, device and terminal equipment. Background technique [0002] In the Rel-16 NR-V2X Mode2 resource allocation mechanism, the user equipment (User Equipment, UE) resource selection process is as follows: [0003] A) The UE will reserve the resources within the resource selection window and receive the Reference Signal Receiving Power (RSRP) of the Physical Sidelink Shared Channel (PSSCH) greater than the RSRP threshold according to its own perception results Excluded from the resource selection window; wherein, the RSRP threshold is determined according to the priority of the received service package and the priority of the service package to be sent; [0004] B) After resource exclusion, determine the proportion of available resources. If the ratio of available resources is less than X% of the total resources in the resource sel...
