    Abstract: This application provides a method for obtaining a precoding matrix and an apparatus. The method includes: respectively obtaining autocorrelation matrices of N terminals based on channel estimation results of the N terminals, where the autocorrelation matrices are filtered in frequency domain and/or time domain to obtain statistical autocorrelation matrices; obtaining a joint precoding matrix of M terminals based on the statistical autocorrelation matrices respectively corresponding to the N terminals; and outputting information that indicates the joint precoding matrix, where the N terminals belong to the M terminals, M≥2, 1≤N≤M, and M and N are both positive integers.
