METHOD AND APPARATUS FOR SETTING PRE-CODING CODEBOOK

摘要

The present invention discloses a method and an apparatus for setting a pre-coding codebook, and the method comprises that the pre-coding codebook is set, wherein the pre-coding codebook is composed of a first class pre-coding matrix set and a second class pre-coding matrix set, the first class pre-coding matrix set contains X matrixes with four rows and three columns, and the second class pre-coding matrix set contains Y matrixes with four rows and three columns; X+Y=N, N is the total number of the matrixes contained in the pre-coding codebook, the numeric range of N is 6-40, the numeric range of X is 0-N, and the numeric range of Y is 0-N. By adopting the present invention, a base station can reasonably select pre-coding matrixes according to the condition of the channel and the scene where user equipment is positioned, thus improving the whole transmission performance and effect of the system.
