Problems solved by technology

However, the number of SL resources in an SL resource pool or the number of SL resources in an SL resource pool cycle or the number of SL resources in a given time (for example, 10240ms) may not be guaranteed to be an integer multiple of the PSFCH cycle
At this time, some SL resources will not meet the PSFCH of the preset mapping relationship, thus affecting transmission and / or feedback
Therefore, in the prior art, there is a problem of low reliability of SL transmission

Abstract

The invention discloses a side link resource processing method, a resource determining method and related equipment. The method comprises the following steps: acquiring side link SL resource pool configuration; determining SL resources and feedback resources in a first time period according to the SL resource pool configuration; under the condition that the SL resources comprise target SL resources meeting a first condition, determining an operation behavior, wherein the feedback resource comprises a first feedback resource with a period of N. The first condition is that a first feedback resource satisfying a first mapping relationship with the target SL resource does not exist, or at least two feedback resources satisfying a first mapping relationship with the target SL resource exist, and the first mapping relationship is a mapping relationship between the first feedback resource and the SL resource. According to the embodiment of the invention, the reliability of SL transmission is improved.

Description

Technical field [0001] This application belongs to the technical field of communication, and more particularly to a side link resource processing method, resource determination method and related equipment. Background technique [0002] In the V2X system, the Physical Sidelink Feedback Channel, PSFCH resource is used to transfer feedback from the side link (Sidelink, SL) transmission block based on the femaback, and TB). The transmitting end (TX UE) can determine whether the next PSSCH retransmission is determined according to the feedback result transmitted by the previous physical Sidelink Shared Channel, PSSCH. At present, PSFCH resources are periodic, cycles are Periodpsfchresource, PeriodPsfchresource can be 1,2,4 SL time slots (slot), each SL SLOT can be called SL resources. However, the number of SL resources in the SL resource in the SL resource pool or the number of SL resources in the SL resource pool or a given time (for example, 10240ms) may not guarantee the integer ...
