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: This application relates to a resource selection method and a first terminal. The method includes: before determining a first transmission resource used to transmit a first transport block, a first terminal determines first duration required by the first terminal to perform first LBT, and determines an unavailable resource in a resource selection window based on the first duration; and/or determines second duration required by a second terminal to perform second LBT, and determines an unavailable resource in the resource selection window based on the second duration. The first terminal selects the first transmission resource based on at least one of the first unavailable resource or the second unavailable resource.

Abstract: Embodiments of this application provide a resource configuration method and a device. According to this method, a first terminal device may reserve N resources based on listen before talk LBT durations corresponding to N transmission requirements. Because the LBT durations are considered, cases in which an LBT duration of a transmission requirement has not ended when a resource corresponding to the transmission requirement arrives can be reduced, so that a probability that the first terminal device can transmit data on the resource corresponding to the transmission requirement can be increased, thereby ensuring communication efficiency of the terminal device.
