Abstract: A resource selection method includes: A first terminal device determines an initial candidate resource set including M resources, and determines, based on an RSRP and a collision index that are associated with SCI received in a sensing window, whether to exclude an ith resource in the M resources from the initial candidate resource set, to obtain a candidate available resource set. The collision index is an index of a collision between a reserved resource indicated by the SCI received in the sensing window and an ith periodic resource. The ith periodic resource includes the ith resource and a resource obtained after the ith resource is extended based on a preset first period. Herein, M is a positive integer, and i is a positive integer from 1 to M.

Abstract: A resource processing method includes a first device receiving first sidelink control information (SCI) having first indication information. The first indication information indicates a first time-frequency resource, and the first indication information further indicates the first device to send second SCI. The first device sends the second SCI. The second SCI includes second indication information indicating a second time-frequency resource. The first time-frequency resource is a time-frequency resource reserved for a second device to send data to the first device or a time-frequency resource that is reserved for the second device to send data to the first device and that is reserved for the first device to receive data. The second time-frequency resource is a time-frequency resource reserved for the first device to receive data.

Abstract: This application provides a communication method and apparatus. The method includes: A first device receives a control channel and a first data channel, where the first device receives the control channel and the first data channel based on a same spatial domain receive parameter, or the first device receives both the control channel and the first data channel through an omnidirectional beam, and indication information of a spatial domain receive parameter of a second data channel is carried on the control channel and/or the first data channel. The first device receives the second data channel based on the indication information. In this application, the first device may first determine the spatial domain receive parameter of the second data channel based on the indication information of the spatial domain receive parameter of the second data channel in the control channel or the first data channel.

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.
