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.

Abstract: This application provides example communication methods and example terminal apparatuses. One example method includes obtaining, by a first terminal apparatus, resource pool configuration information, where the resource pool configuration information includes information about a physical sidelink control channel (PSCCH) time domain resource. The first terminal apparatus can then determine a PSCCH frequency domain resource based on the resource pool configuration information and a format of control information. The first terminal apparatus can then send the control information to a second terminal apparatus, where the control information is carried on a PSCCH time-frequency resource, and where the PSCCH time-frequency resource includes the PSCCH time domain resource and the PSCCH frequency domain resource.

Abstract: A beam training method and a related device are disclosed. The method includes: sending, by a first communications device, sidelink control information (SCI) to a second communications device, where the SCI is used to instruct the first communications device to send at least one channel state information-reference signal (CSI-RS) to the second communications device; and sending, by the first communications device, the at least one CSI-RS to the second communications device based on the SCI, where the at least one CSI-RS is used by the second communications device to determine that a beam corresponding to a CSI-RS with highest signal strength in the at least one CSI-RS is a beam for communication between the second communications device and the first communications device. The CSI-RS used for beam training is dynamically sent based on the instruction of the SCI, and therefore, flexibility and efficiency of beam training are improved.

Abstract: This application provides a sidelink feedback information transmission method and a communication apparatus. The method includes: A first terminal sends first indication information to a second terminal, where the first indication information indicates that first channel occupancy time includes a first physical sidelink feedback channel PSFCH resource; and the first terminal receives, on the first PSFCH resource, feedback information from the second terminal. In this application, the second terminal sends the feedback information by using a resource contended by the first terminal. Compared with a solution in which the second terminal contends for a resource to send the feedback information, this solution in this application can reduce a possibility of a contention failure of the second terminal, and improve accuracy of data transmission.
