Abstract: This application provides a sidelink configuration method and apparatus, a device, and a storage medium. In one example, before each sidelink transmission is performed, a terminal device at a transmit end sends SCI to a terminal device at a receive end. In this solution, transmission on information needed for sidelink transmissions is performed by using sidelink RRC, so that the terminal device at the receive end obtains a time-frequency resource configuration of sidelink transmissions, and further obtains a HARQ process identifier of each transmission.

Abstract: When a channel is not occupied within a first COT, a network device sends indication information to a terminal device within the first COT, where the indication information is used to indicate that the channel is not occupied within the first COT. When the channel is occupied within the first COT, the network device obtains a second COT within the first COT, and sends start information of the second COT to the terminal device. Correspondingly, when receiving the indication information, the terminal device may perform blind PDCCH detection in a first manner. If the terminal device does not receive the indication information, it indicates that the channel is occupied within the first COT, and the terminal device performs blind detection on the start information of the second COT.

Abstract: A feedback method and apparatus which are used to provide a feedback mechanism in a sidelink communications system, and may be applied to the internet of vehicles, for example, V2X, LTE-V, and V2V. The method includes: a first terminal device determines that a feedback condition is met, and sends feedback information to a second terminal device, where the feedback information includes at least one of channel state information and a receive response, and the receive response includes a positive acknowledgment, a negative acknowledgment, or discontinuous transmission. In this way, the feedback condition is set, so that the first terminal device sends the feedback information only when the feedback condition is met. In this way, resource overheads and information redundancy that are caused when each terminal device in a communication group sends feedback information are effectively avoided.
