Abstract: This application provides a CSI measurement method and apparatus. In the method, a terminal may send, to a network device, a first RS that occupies a plurality of frequency domain resource segments in one time domain unit, where the plurality of frequency domain resource segments are discontinuously distributed on a frequency band of the terminal, and the network device receives the first RS on a corresponding frequency domain resource segment, and measures CSI based on the first RS. Currently, to avoid channel aging, a method is to shorten an SRS periodicity. Because frequency domain resources occupied by the SRS are continuously distributed on an entire frequency band, this method leads to a waste of time-frequency resources. However, the first RS in this application is discontinuously distributed on a frequency band of the terminal, and a relatively small quantity of time-frequency resources are occupied.
