Abstract:
A precoding matrix determining method and apparatus are provided. A terminal determines a precoding matrix, where the precoding matrix includes at least two column vector sets, a column vector associated with any column vector set of the at least two column vector sets exists in the at least two column vector sets, and both the any column vector set and the associated column vector are applied on different polarization antennas; the terminal determines a first precoding matrix indicator (PMI) and a second PMI based on the precoding matrix; and the terminal sends the first PMI and the second PMI to a base station. In this solution, different column vectors are applied to different polarization antennas. Therefore, a prior-art defect of unbalanced beam coverage performance is overcome.

Claim (Index 3):
The method according to  claim 1 , wherein the precoding matrix satisfies the following rule: W = [ v n 1 v n 2 \u2026 v n k \u03d5 1 \ue89e v m 1 \u03d5 2 \ue89e v m 2 \u2026 \u03d5 K \ue89e v m k \ue89e ] , wherein\n v n k  and v m k  indicate an n k th  column vector and an m k th  column vector that are in a vector group set, v n k  is associated with v m k , n k \u2260m k  is satisfied, k=1, 2, . . . , K, and \u03d5 i  is a phase compensation factor.
