Abstract

An embodiment of the present invention provides a HARQ feedback method, a first terminal, and a computer-readable storage medium. The method includes: receiving information carried by PSCCHs and PSSCHs of at least two second terminals in the same time window, and the first terminal and each The transmission configuration of a second terminal requires sidelink HARQ ACK / NACK feedback; according to the information carried by the PSCCH and PSSCH of all the second terminals received, and / or the transmission configuration information of the first terminal and each second terminal, Determine to perform sidelink HARQ ACK / NACK feedback on the PSSCH of at least one second terminal. The embodiments of the present invention can reduce feedback conflicts.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a HARQ feedback method, a first terminal and a computer-readable storage medium. Background technique [0002] In the 5G new air interface (New Radio, NR) system, it supports greater bandwidth, higher throughput, more complex services, and more complex processing technologies that match it. With the further development of the Internet of Vehicles technology, some new application scenarios have emerged, such as vehicle formation, advanced driving, sensor information sharing, and remote control application scenarios. In these application scenarios, broadcast, multicast, and unicast communication modes are required to be provided on the sidelink (the link for direct communication between the terminal (UE) and the terminal). These application scenarios put forward higher requirements for the sidelink between UEs, requiring larger data packets, higher transmission ...
