Abstract

The invention discloses a sidelink feedback resource configuration method, an information processing method and equipment, and belongs to the field of communication. The sidelink feedback resource configuration method comprises the following steps: acquiring resource configuration information; determining a sidelink feedback resource corresponding to a target mapping mode according to the resource configuration information, wherein the target mapping mode is one of a plurality of mapping modes corresponding to the same resource pool. Therefore, the understanding of each terminal device on the auxiliary link feedback resource configuration can be kept consistent, and the coexistence of mapping modes with different feedback periods is realized, so the auxiliary link feedback resource conflict is avoided. Furthermore, the terminal equipment can support the configuration of a plurality of mapping modes in the same resource pool, and the terminal equipment configured with different mapping modes can communicate with each other. Meanwhile, the terminal equipment can flexibly adapt to various communication requirements.

Description

technical field [0001] The present application relates to the communication field, and in particular to a secondary link feedback resource configuration method, information processing method and equipment. Background technique [0002] Currently, a Long Term Evolution (Long Term Evolution, LTE) system supports transmission of a side link (Sidelink, SL, which may also be referred to as a side link, a side link, or a side link, etc.). The SL is used for direct data transmission between user equipments (User Equipment, UE, also referred to as terminal equipment) without going through network equipment. The new air interface (New Radio, NR) system that can be used in the working frequency band above 6 GHz that is not supported by the LTE system and supports a larger working bandwidth also supports Sidelink interface communication for direct communication between UEs. [0003] Wherein, the UE sends sidelink control information (Sidelink Control Information, SCI) through a physic...
