Abstract:
The present disclosure provides a method of generating codebook in a wireless communication system with multiple antenna arrays, as well as a wireless communication system, base station and terminal using the 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 precision of feedback for multi-antenna array is kept by applying the method of generating codebook and using the generated codebook in the wireless communication system, base station and terminal.

Claim (Index 5):
The integrated circuit according to  claim 1 , wherein:\n the at least one output, in operation, outputs the pre-coded data for transmission from a base station apparatus using two layers, the basic pre-coding column vectors included in the first basic codebook respectively include basic pre-coding matrix vectors w m  for one of the two layers and basic pre-coding matrix vectors w\u2032 m  for another one of the two layers, where m is an integer; and an angle difference between the vectors w m  and w\u2032 m  is selected from a set of angles including: 2\u03c0/32, 4\u03c0/32 and 6\u03c0/32.
