Abstract: A wireless communication method includes receiving, by a terminal device, first information sent by a network device. The first information includes a first offset. The first offset is a difference between a frame number of a first system frame and a frame number of a first direct frame. The first system frame and the first direct frame overlap in a time domain. The wireless communication method also includes determining, by the terminal device, the first direct frame based on at least one of the first offset or the frame number of the first system frame.

Abstract: The present disclosure relates to sidelink communication methods and apparatus. In one example method, a terminal device sends first information to a network device, where the first information includes a first destination address, a first carrier index, and a first quality of service (QoS) parameter, and there is a correspondence between the first destination address, the first carrier index, and the first QoS parameter. The network device receives the first information from the terminal device. The network device determines sidelink radio bearer (SLRB) configuration information based on the first information, and sends the SLRB configuration information to the terminal device. The terminal device receives the SLRB configuration information from the network device.
