Abstract: Embodiments of the present invention provide a communication method. A first network device configures power configuration information for each of at least two precoding matrix groups, and sends the power configuration information to a second network device. The power configuration information is used to indicate a power configuration of a corresponding precoding matrix group of the at least two precoding matrix groups, and the at least two precoding matrix groups belong to a same resource used to measure channel state information CSI. When the second network device performs CSI measurement, different power values of different precoding matrix groups can be considered, thereby increasing accuracy of the CSI measurement.
