Abstract: This application provides a communication method, apparatus, and system. In the method, a terminal receives channel state information-reference signal (CSI-RS) configuration information. When a CSI-RS resource configured by a network device includes both a resource for uplink transmission and a resource for downlink transmission, the CSI-RS resource is divided into a plurality of resource sets, so that the terminal device performs CSI-RS measurement only on the resource for downlink transmission, to avoid impact of CSI-RS measurement performed by the terminal on the uplink resource. This improves accuracy of channel measurement, so that communication performance can be further improved.
