METHOD AND APPARATUS FOR GENERATING A PRECODING MATRIX CODEBOOK GROUP

摘要

A method and an apparatus for generating a precoding matrix codebook group are provided by the present invention. The method includes: a step for generating a channel matrix set; a step for generating a performance parameter matrix; and a step for generating a precoding matrix codebook group: based on the generated performance parameter matrix, according to contribution of every precoding matrix to the performance parameter of the communication system, ranking the precoding matrices in precoding matrix universal set, so as to achieve an ordered precoding matrix universal set as the precoding matrix codebook group. A method for assigning a precoding matrix for a multi-antenna communication system, a method for transmitting data for a multi-antenna communication system, a base station and a mobile station thereof are provided by the present invention.
