Abstract: Embodiments of this application provide a communication method: A first terminal device sends first information to at least one second terminal device, to indicate the at least one second terminal device to perform feedback. The first terminal device receives a feedback of a third terminal device, where the third terminal device is a terminal device that is in the at least one second terminal device and that has performed feedback. The first terminal device sends first resource indication information, to indicate a first resource, where the first resource is for the third terminal device to perform transmission, and the first resource is included in a channel occupancy time COT preempted by the first terminal device. A UE 1 allocates a COT resource to a UE 2 that has performed feedback. This can reduce resource waste, avoid COT interruption, improve spectrum resource utilization and improve system transmission performance.

Abstract: A communication method and a communications device are disclosed. A first device in a communications system separately sends, to a second device, responses used to indicate a transmission result of target data: a first response and a second response. An indication manner of the first response is different from an indication manner of the second response. This approach can improve flexibility of a response indication manner. Therefore, the communications system can flexibly adjust indication manners of responses sent at different times to ensure indication precision of the responses while reducing transmission resources of the responses.
