WIRELESS COMMUNICATION SYSTEM, BASE STATION, TERMINAL AND METHOD OF GENERATING CODEBOOK

摘要

FIELD: radio engineering, communication.SUBSTANCE: invention relates to a wireless communication system comprising a base station and terminal using a generated codebook. The device and method of generating a codebook in a wireless communication system with multiple antenna arrays use said codebook for communication. The method comprises steps of: providing a basic codebook which contains multiple pre-coding matrices; and assigning phase offsets to certain pre-coding matrices in the basic codebook to form a codebook with phase offset. The feedback overhead from a client to a base station side is reduced and a good accuracy of feedback for a multielement antenna array is maintained.EFFECT: high accuracy of feedback for a multielement antenna array.20 cl, 1 tbl, 13 dwg
