Abstract: A communication method includes receiving N pilot signals from a network device by using N channel state information (CSI) resources. The N CSI resources are in a one-to-one correspondence with the N pilot signals, N is an integer greater than or equal to 2, and the N pilot signals correspond to N mapping relationships between antenna ports of the network device and transceiver antennas of the network device, wherein at least two of the N mapping relationships between the antenna ports of the network device and the transceiver antennas of the network device are different, or the N pilot signals correspond to N inter-polarization phases, wherein at least two of the N inter-polarization phases are different. The method also includes performing channel measurement on the N CSI resources based on the corresponding pilot signals. The method further includes sending channel state information to the network device.
