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.

Abstract: This application relates to a communication method, apparatus, and system, and is applicable to fields such as internet of vehicles, intelligent driving, assisted driving, and intelligent connected vehicles. A first terminal apparatus detects sidelink control information from at least one second terminal apparatus to determine a first time-frequency resource. The first terminal apparatus sends first information to a third terminal apparatus, to trigger determining of second information. The first terminal apparatus receives the second information from the third terminal apparatus, to indicate a second time-frequency resource. The first terminal apparatus determines the third time-frequency resource based on the second time-frequency resource and the first time-frequency resource. The first terminal apparatus may use both a sensing result of the first terminal apparatus and a sensing result of the third terminal apparatus as consideration factors to select a resource for sending data, to improve signal received quality.

Abstract: A sidelink resource determining method includes determining, by a first terminal device, a first sidelink candidate resource through monitoring. The method also includes receiving, by the first terminal device, at least one piece of resource indication information from a second terminal device. The at least one piece of resource indication information indicates at least one second sidelink candidate resource obtained by the second terminal device through monitoring. The method further includes determining, by the first terminal device, a sidelink sending resource based on the first sidelink candidate resource and based on the at least one second sidelink candidate resource. The method additionally includes sending, by the first terminal device, sidelink control information and data on the sidelink sending resource.

Abstract: A communication method and apparatus that is used in fields such as V2X, an internet of vehicles, intelligent driving, and assisted driving. The method includes a first terminal apparatus detects SCI from at least one second terminal apparatus, to determine a first resource. The first terminal apparatus sends, to the third terminal apparatus, first information for triggering determining of second information, and receives the second information from the third terminal apparatus. The first terminal apparatus determines, based on the first resource and the second resource, the resource for sending the data. The first terminal apparatus selects, based on a sensing result of the first terminal apparatus and the resource recommended by the third terminal apparatus, the resource for sending the data, so that both interference around the first terminal apparatus and interference around the third terminal apparatus are considered, thereby reducing interference and improving communication quality.
