Abstract

The present application provides a resource selection method, apparatus and terminal device. It relates to the field of communication technologies, and the method is applied to a coordinated UE of a V2X direct link system. The method includes: sending direct link resource coordination request information; receiving direct link resource coordination information of the coordinating UE; The coordination information is used for resource selection of the direct link. The present application can solve the problem that the overhead of the direct link resource coordination information is too large due to the imperfect direct link resource coordination request information, the timeliness of the direct link resource coordination information is poor, and the direct link resource coordination request information overhead is uncertain due to the direct link. The problem of uncertainty about the way in which the road resource coordination request information is carried is uncertain.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a resource selection method, apparatus, and terminal device. 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) According to its own perception results, the UE will reserve resources within the resource selection window and the received Reference Signal Receiving Power (RSRP) of the Physical Sidelink Shared Channel (PSSCH) is greater than the RSRP threshold. 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 to-be-sent service package; [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...
