Abstract

The invention discloses an Internet of Vehicles communication feedback method, which comprises the following steps: downlink control information comprising indication information, and the indication information representing the time position of one or more uplink control channels; wherein the uplink control channel is used for bearing uplink control information; wherein the uplink control information comprises hybrid automatic repeat request feedback information of sidelink communication. The invention further provides a network device, a terminal device and a system which apply the method. The scheme of the invention solves the problem of how to reduce the feedback delay and improve the resource efficiency when the network device indicates the sending end terminal device to feed back theSL HARQ.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a timing method and device for communication feedback of the Internet of Vehicles. Background technique [0002] In the IoV communication, side link (SL) will be used to support terminal-to-terminal communication, and side link hybrid automatic repeat request feedback (SL HARQ) in unicast / multicast scenarios will be supported, where SL The HARQ information will be indicated by the Side Link Feedback Control Information (SFCI) carried by the Side Link Feedback Channel (PSFCH). The terminal device at the receiving end will feed back SLHARQ to the terminal device at the transmitting end, and then the terminal device at the transmitting end will transmit it to the network device (such as base station). [0003] When the base station indicates the transmission resources for SL to the terminal equipment at the sending end, it can indicate the initial transmi...
