Abstract

The invention relates to the technical field of communication, in particular to a feedback information transmission method and device, a terminal and a storage medium. The method comprises the following steps: when the HARQ-ACK information of the side chain needs to be sent in the target time unit, sending the HARQ-ACK information of the side chain to the target time unit; and the first terminal sending a side link HARQ-ACK codebook on a physical layer uplink channel in the target time unit, wherein the side link HARQ-ACK codebook comprises side link HARQ-ACK information corresponding to at least one piece of side link data. According to the method, the first terminal can support data transmission when the side chain HARQ-ACK information needs to be sent in the target time unit. The condition that the first terminal cannot correspond the side chain resources to the PDSCH SLIV when the DCI contains the side chain resources in the related technology is avoided, and the success rate of side chain HARQ-ACK codebook feedback in a side chain communication scene is ensured.

Description

Technical field [0001] The present disclosure relates to the field of communication technology, and in particular to a method, device, terminal and storage medium for transmitting feedback information. Background technique [0002] In the Vehicle to Everything (V2X) technology, vehicle-mounted devices and other devices (such as other vehicle-mounted devices, roadside infrastructure, etc.) can communicate with each other through sidelinks (English: sidelink). [0003] In the related art, the side-chain communication method based on the scheduling of access network equipment includes: the access network equipment sends scheduling information to the side-chain communication sending end user equipment (referred to as the first) through Downlink Control Information (DCI). Terminal), the first terminal sends the side-chain resource to the side-chain communication receiving end user equipment (referred to as the second terminal for short) according to the scheduling information of the acc...
