Title:
FEEDBACK INFORMATION TRANSMISSION METHOD AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/017792
Kind Code:
A1
Abstract:
A feedback information transmission method and terminal device. Said method can be applied to the Internet of Vehicles, such as V2X, LTE-V and V2V, or can be applied to fields such as intelligent driving and intelligent connected vehicle. Said method comprises: after a first terminal device has received at least two data packets on a sidelink, the first terminal device sending, according to priorities of at least two pieces of feedback information for the at least two data packets, at least one piece of feedback information among the at least two pieces of feedback information. In this way, upon reception of multiple data packets, the terminal device can determine, according to the priorities of the multiple pieces of feedback information corresponding to the multiple data packets, to send one or more pieces of feedback information among the multiple pieces of feedback information. Provided is a solution by which the terminal device can perform HARQ feedback for multiple data packets. Furthermore, sending feedback information according to priorities can reduce a transmission delay of a service having a high priority, and can improve a resource utilization rate of a sidelink.
