Abstract

The present application provides a method and a communication device for transmitting sidelink feedback information, which can be applied to systems such as Internet of Vehicles, V2X, and V2V. The method includes: sending sidelink information to the first terminal device on the first channel The side link scheduling information is used to schedule the first terminal device to send side data to the second terminal device on the side link; determine the second channel, and the second channel is used to receive data from the first terminal device. HARQ information of the sidelink data. In the method provided by this application, after sending the sidelink scheduling information to the first terminal device on the first channel, by determining the position of the second channel, it is clear that the information received on the second channel is HARQ information of sidelink data scheduled on the channel. It is clarified that the HARQ information is aimed at the HARQ process scheduled by the first channel, which ensures that the data retransmission mechanism on the sidelink can be effectively realized.

Description

[0001] This application is a divisional application of the patent application No. 201910760454.1, titled "Method and Communication Device for Sidelink Feedback Information Transmission". technical field [0002] The present application relates to the field of communication, and more specifically, to a method and a communication device for transmitting sidelink feedback information. Background technique [0003] Vehicle to everything (V2X) communication is an important key technology to realize environment perception and information interaction in the Internet of Vehicles. The communication link between different user terminal equipment may be called a sidelink (sidelink, SL). Vehicle-to-everything (V2X) communication with other entities (entity) may be performed using sidelinks. Physical resource allocation in V2X communication includes two allocation methods: the first allocation method is based on the scheduling of network equipment (such as base stations), and the user e...
