Abstract
This application discloses methods and apparatuses for determining precoding vector. One example method includes: determining, by a network apparatus, a precoding vector of one or more frequency domain units based on the first indication information. The first indication information is used to indicate Lbeam vectors in a beam vector set, Kfrequency domain vectors in a frequency domain vector set, and Tspace-frequency component matrices. A weighted sum of the Tspace-frequency component matrices is used to determine a precoding vector of each frequency domain unit. The Tspace-frequency component matrices are selected from Mspace-frequency component matrices corresponding to the Lbeam vectors and the Kfrequency domain vectors, each space-frequency component matrix is uniquely determined by one beam vector and one frequency domain vector.
