Abstract: This application provides a sidelink feedback information transmission method and a communication apparatus. The method includes: A first terminal sends first indication information to a second terminal, where the first indication information indicates that first channel occupancy time includes a first physical sidelink feedback channel PSFCH resource; and the first terminal receives, on the first PSFCH resource, feedback information from the second terminal. In this application, the second terminal sends the feedback information by using a resource contended by the first terminal. Compared with a solution in which the second terminal contends for a resource to send the feedback information, this solution in this application can reduce a possibility of a contention failure of the second terminal, and improve accuracy of data transmission.

Abstract: A data transmission resource determining method, a device, and a system are applicable to fields such as the Internet of vehicles, intelligent connected vehicles, assisted driving, and intelligent driving, and can improve transmission flexibility and reduce transmission overheads. In this solution, a terminal device determines an initial time interval and an interval difference, and determines, based on the initial time interval and the interval difference, a time domain position of a first time-frequency resource used when a first TB is transmitted for the ith time. The initial time interval is a time interval between a time domain position at which the first TB is transmitted for the first time and a time domain position at which the first TB is transmitted for the second time, and the interval difference is a difference between a first time interval and a second time interval.
