Method and apparatus for constructing codebook, and method, apparatus and system for precoding
Abstract:
The present invention discloses a method and apparatus for constructing a codebook. The method comprises: receiving grouping information on a plurality of transmit antennas of a base station; obtaining a channel model for a channel between a mobile terminal and the base station; and determining an optimal precoding matrix corresponding to each antenna group according to the grouping information and the channel model, so as to construct a codebook used for precoding. The present invention further discloses a method and apparatus for selecting a precoding matrix, as well as a method, apparatus and system for precoding.
