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 L1 beam vectors in a beam vector set, K1 frequency domain vectors in a frequency domain vector set, and T1 space-frequency component matrices. A weighted sum of the T1 space-frequency component matrices is used to determine a precoding vector of each frequency domain unit. The T1 space-frequency component matrices are selected from M1 space-frequency component matrices corresponding to the L1 beam vectors and the K1 frequency domain vectors, each space-frequency component matrix is uniquely determined by one beam vector and one frequency domain vector.
