Abstract

The invention discloses a sidelink feedback resource configuration method and device, and equipment, which belong to the field of communication. The method comprises the following steps of: acquiring resource configuration information; and 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, and code domain multiplexing is carried out between the sidelink feedback resource corresponding to the target mapping mode and the sidelink feedback resource corresponding to the first mapping mode in the plurality of mapping modes. By adopting the sidelink feedback resource configuration method and device of the invention, the understanding of each set of terminal equipment on sidelink feedback resource configuration can be kept consistent, the coexistence of mapping modes with different feedback periods is realized, and the conflict of the sidelink feedback resources 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, thereby flexibly adapting 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, device, 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.). SL is used for direct data transmission between user equipment (User Equipment, UE, also called terminal equipment) without going through network side 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 physical sidelink control channel (P...
