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.

Abstract: This application may be applied to an internet of vehicles, for example, V2X and LTE-V. A first terminal apparatus determines, a first resource pool. The first terminal apparatus detects control information of a second terminal apparatus, where the control information indicates second service data of the second terminal apparatus, and the control information includes location information of the second terminal apparatus, a first frequency domain resource, and a periodicity of the second service data. The first terminal apparatus determines an unavailable time-frequency resource in the first resource pool based on location information of the first terminal apparatus, the location information of the second terminal apparatus, a first threshold, the first frequency domain resource, and the periodicity of the second service data. The first terminal apparatus selects a first time-frequency resource from available time-frequency resources in the first resource pool to transmit first service data.
