Abstract: This application relates to a communication method, an apparatus, and a system, and is applicable to fields such as Internet of Vehicles, intelligent driving, assisted driving, and intelligent connected vehicles. The method includes: determining a first time based on a first reference time and a first time offset, and sending, to a first terminal apparatus at the first time or before the first time, coordination information indicating a first resource, where the first resource is for determining a second resource for receiving sidelink information from the first terminal apparatus. Therefore, the time for sending the coordination information is limited. This ensures that the first terminal apparatus has sufficient time to determine, when the first terminal apparatus receives the coordination information, the second resource for sending the sidelink information, thereby improving reliability of sidelink communication.

Abstract: A method for configuring a sidelink transmission resource is provided, including sending, by a network device, downlink control information (DCI) to a first terminal apparatus, the DCI comprising one or both of a first indication information or a second indication information. The first indication information indicating a time domain resource on which the first terminal apparatus sends sidelink hybrid automatic repeat request (HARQ) information to the network device, and the second indication information indicating a frequency domain resource on which the first terminal apparatus sends the HARQ information to the network device. The method further includes receiving, by the network device, the HARQ information from the first terminal apparatus based on the one or both of the first indication information or the second indication information.
