Abstract: A communication method, a terminal apparatus, and a system. A first terminal apparatus and a second terminal apparatus determine, based on first configuration information, a plurality of candidate resources in a slot, and perform sidelink communication based on the candidate resources. A first symbol in any candidate resource in one slot is used to send first information. In response to a channel access moment of the first terminal apparatus being after a start moment of a first symbol in one candidate resource in a first slot, the first terminal apparatus further sends the first information based on the first symbol in another candidate resource after the channel access moment, without waiting for a next slot after the first slot. In this way, a sidelink communication delay is reduced.

Abstract: A communication method and an apparatus relate to fields such as V2X, intelligent connected vehicles, intelligent driving, and assisted driving, to resolve a technical problem that a current SL lacks an indication of an SL TCI identifier. The SL TCI identifier is able to be implemented in at least two ways. An explicit indication is able to be used. A first terminal apparatus sends first indication information to a second terminal apparatus. The second terminal apparatus determines the SL TCI identifier of the first reference signal based on the first indication information. Alternatively, a first terminal apparatus generates a first signal based on an SL TCI identifier of the first signal, and sends the first signal to a second terminal apparatus. Then, the second terminal apparatus determines the SL TCI identifier of the first signal based on the first signal.
