Abstract
A method for obtaining a precoding matrix includes obtaining a joint precoding matrix of M terminals based on statistical autocorrelation matrices respectively corresponding to N terminals in the M terminals, where M and N are positive integers, M≥2, and 1≤N≤M. The method further includes outputting information that is useable to indicate the joint precoding matrix. The N terminals include a terminal n, wherein a statistical autocorrelation matrixcorresponding to the terminal nis obtainable by filtering an autocorrelation matrix Rcorresponding to the terminal nin a frequency domain or a time domain, j is a positive integer, 1≤j≤N, and the autocorrelation matrix Rcorresponding to the terminal nis obtainable based on a channel estimation result Hcorresponding to the terminal n.
