    摘要: Embodiments of the present invention disclose a communication method, apparatus, and system. The method includes: A first terminal device sends a wake-up signal to a second terminal device by using a first frequency domain resource, where the wake-up signal is used to activate a second frequency domain resource, the first frequency domain resource is used by two or more terminal devices to transmit wake-up signals, and the first frequency domain resource does not overlap the second frequency domain resource; and the first terminal device sends sidelink SL data to the second terminal device by using the second frequency domain resource. Embodiments of the present invention can reduce power consumption of the terminal devices in sidelink communication.

    摘要: A first terminal apparatus sends K2 first reference signals to a second terminal apparatus in K1 directions. The first terminal apparatus determines that beams in the K1 directions all fail for N1 consecutive times. The first terminal apparatus sends P2 second reference signals to the second terminal apparatus in P1 directions. The first terminal apparatus determines, based on measurement results that are of the P2 second reference signals and that are from the second terminal apparatus, whether P1 beams corresponding to the P1 directions are available.

    摘要: This application provides a channel measurement method and an apparatus, which may be used in a field such as vehicle-to-everything V2X, smart internet of vehicles, autonomous driving, or an unmanned driving. In a sidelink channel report procedure, a transmit end apparatus for sidelink communication indicates one or more candidate time intervals to a receive end apparatus. The receive end apparatus may attempt to obtain an available PSSCH for sending a channel measurement report on one or more time domain resources corresponding to the one or more candidate time intervals.

    摘要: This application provides a wireless communication method and apparatus. The method includes: determining N first symbols in a first slot, where N is a positive real number greater than 1 and less than M, M is a quantity of symbols included in the first slot, M is a positive integer, a frequency domain resource corresponding to the first slot is an unlicensed spectrum, and the first symbols are unoccupied symbols in the first slot; and sending a first signal to a terminal device on the N first symbols. The first signal includes at least one of the following: a symbol copied from a second slot, a to-be-sent first transport block, or a cyclic prefix extension. The second slot is a next slot of the first slot. According to the disclosure, a channel resource in an unlicensed spectrum can be effectively occupied, thereby reducing waste of channel resources.

    摘要: This application provides a configuration information indication method and an apparatus, which are applicable to fields such as vehicle to everything V2X, intelligent connected vehicles, assisted driving, and intelligent driving, to resolve an existing-technology problem that SL transmission causes interference to DL transmission, and effectively reduce signaling overheads. This method is applied to a first terminal device, and includes: receiving an uplink-downlink time division multiplex TDD configuration sent by a network device; and sending indication information to a second terminal device based on the uplink-downlink TDD configuration, where the indication information is carried on a physical sidelink broadcast channel PSBCH of a sidelink synchronization signal block S-SSB, and the indication information is used to indicate periodicity information included in the uplink-downlink TDD configuration.
