Abstract: Embodiments of this application disclose a communication method and apparatus. Therefore, a beam gain of downlink channel transmission is improved, and a phase mismatch performance loss is small. The method in embodiments of this application includes: A network device may determine a first downlink statistical autocorrelation matrix of a downlink channel based on a first uplink statistical autocorrelation matrix of an uplink channel, indicate, based on a first weight indicated by a terminal, the terminal to receive a second weight of data, then determine a third weight different from the second weight based on the first downlink statistical autocorrelation matrix and the second weight, and send the data to the terminal based on the third weight.
