Abstract: Embodiments of this application provide a PSFCH sending method and an apparatus, and relate to the field of communication technologies, in particular, to V2X, an intelligent vehicle, autonomous driving, an intelligent connected vehicle, and the like. The method may include: A first terminal apparatus receives first sidelink data from a second terminal apparatus, and determines, based on a transmission resource of the first sidelink data, a feedback resource used to send SFCI. The transmission resource of the first sidelink data and the feedback resource include the same quantity of resource elements, for example, N resource elements, and N is a positive integer. When X resource elements are required for sending first feedback information, and X is less than N, the first terminal apparatus sends at least one piece of SFCI to the second terminal apparatus on the feedback resource through at least one PSFCH. The SFCI includes the first feedback information, and the first feedback information is used to indicate whether the first terminal apparatus correctly receives the first sidelink data.

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.
