Abstract: A communication method and apparatus, and a system. A first terminal device obtains first information, where the first information includes a first multicast and broadcast service MBS service identifier and first sidelink SL resource information. A mapping relationship exists between the first MBS service identifier and the first SL resource information. A first MBS is an MBS supported by a first relay terminal device, and the first SL resource information is usable for transmitting data of the first MB S to the first terminal device. The first terminal device receives, based on the first SL resource information, the data that is of the first MBS and that is sent by the first relay terminal device. The first terminal device transmits MBS data in a scenario in which a relay terminal device supports an MBS service.

Abstract: A communication method, apparatus, and system are provided. In the method, the second user equipment receives first information from a first user equipment, where the first information includes an identifier of a first multicast broadcast service (MBS), and the first MBS is an MBS that the first user equipment is interested in. Also in the method, the second user equipment sends a first message to the first user equipment, where the first message includes first configuration information, the first configuration information is for configuring a sidelink (SL) radio bearer, and the SL radio bearer is for transmitting data of the first MBS. The method can resolve a problem that a remote user equipment cannot receive data of an MBS of a network device because a relay user equipment does not forward, to the remote user equipment, the data of the MBS broadcast by the network device.

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.
