Abstract: This application provides a communication method. The communication method includes: A first device sends indication information, where the indication information is used to indicate whether the first device sends a first synchronization signal block in a synchronization slot of a sidelink, and the synchronization slot is used to transmit a synchronization signal block; and the first device sends first data in the synchronization slot of the sidelink. Because the first device indicates a sending behavior of the first device in the synchronization slot before sending the first data, a receiver may determine a processing manner of the receiver in the synchronization slot based on the indication information.

Abstract: This application discloses a reference signal sending method, a base station, and user equipment, to relieve a problem of low utilization of time-frequency resources. The method may include receiving, by a base station, a measurement result, sent by user equipment (UE), of a downlink reference signal from a serving cell of the UE, where the base station is a base station to which the serving cell belongs. The method may also include determining, by the base station based on the measurement result, whether a predetermined handover preparation condition is met. When the predetermined handover preparation condition is met, the method may include instructing, by the base station, a neighboring cell to send the downlink reference signal to the UE using a time-frequency resource configured by the base station, where the neighboring cell does not send the downlink reference signal to the UE before the neighboring cell is instructed. Furthermore, the method may include instructing, by the base station, the UE to receive the downlink reference signal using the time-frequency resource configured by the base station.

Abstract: Example beam training methods and apparatus are described. In one example method, a first terminal apparatus sends a first message to a second terminal apparatus, where the first message includes a request for a first list, the first list includes an identifier of at least one sidelink synchronization signal, and the at least one sidelink synchronization signal is a sidelink synchronization signal that is not used by the second terminal apparatus within a preset time range and/or that is not used by another terminal apparatus within an area in which the second terminal apparatus is located. The first terminal apparatus receives a second message from the second terminal apparatus, where the second message includes the first list. A first sidelink synchronization signal is determined based on the identifier of the at least one sidelink synchronization signal in the first list. The first sidelink synchronization signal is used for beam training.
