1. A communication method, wherein the communication method comprises:
receiving, by a terminal device, a reference signal sent by a network device, wherein the reference signal has an association relationship with a weight matrix and a channel between the network device and the terminal device, wherein the weight matrix is determined at least based on a predetermined factor associated with transmit power of the network device, and wherein 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; and
determining, by the terminal device, an estimation result of the weight matrix based on the reference signal, wherein:
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
the estimation result of the weight matrix is used by the terminal device to precode a data signal sent by the terminal device to the network device.
