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: The embodiments of the present invention provide a method, apparatus, and system. The method comprises: sending, by a centralized processing node, control information containing address information of a service ERRU and the transmission mode of ERRUs to the ERRUs in a COMP set; receiving the compressed uplink COMP frequency domain data sent by the service ERRU according to the transmission mode, wherein the compressed uplink COMP frequency domain data are data obtained by the service ERRU by compressing the original uplink COMP frequency domain data sent by the non-service ERRUs and the original uplink COMP frequency domain data of the service ERRU, and receiving the original uplink COMP frequency domain data sent by at least one ERRU according to the transmission mode. In the present invention, the data are compressed to reduce the uplink transmission flow between the ERRUs in the COMP set and the centralized processing node.
