Abstract
Example communication methods and apparatus are described. One example method includes receiving a reference signal from a network device by a terminal device. The reference signal has an association relationship with a weight matrix and a channel between the network device and the terminal device, a quantity of rows or columns of the weight matrix is N, and N is a positive integer less than or equal to a quantity of receive ports of the terminal device. The terminal device determines an estimation result of the weight matrix based on the reference signal, where the estimation result of the weight matrix is used by the terminal device to perform signal detection on a data signal received by the terminal device from the network device, or is used by the terminal device to precode a data signal sent by the terminal device to the network device.
