Abstract

Embodiments of this application provide a resource indication information transmission method, a device, and a system, which are applicable to fields such as internet of vehicles, intelligent connected vehicle, assisted driving, and intelligent driving. In an example method, a first terminal device determines X sets of candidate single-time-unit resources based on a number of sub-channels to be used by a second terminal device for physical sidelink shared channel (PSSCH) and/or physical sidelink control channel (PSCCH) transmission, and indicates, to the second terminal device, K candidate single-time-unit resources whose time domain locations are in a first time window in the X sets of candidate single-time-unit resources. The second terminal device determines a first time-frequency resource based on the K candidate single-time-unit resources. The first time window is a time window included in a selection window corresponding to at least one of the X sets of candidate single-time-unit resources.
