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 1):
An integrated circuit, comprising:\n control circuitry which, in operation, controls:\n storing an extended codebook which is generated by combining a first basic codebook and a second basic codebook along a column direction, wherein the first basic codebook includes N groups, each consisting of four basic pre-coding column vectors (N is a natural number equal to or larger than 2), and wherein the second basic codebook is generated by applying phase offsets to the N groups, respectively, each of the phase offsets, applied to the N groups, being different from each other; \n receiving, from a terminal apparatus via a multi-antenna array, information including a pre-coding matrix indicator (PMI) that identifies one pre-coding extended column vector from among 4N pre-coding extended column vectors included in the extended codebook; \n pre-coding data using the pre-coding extended column vector identified by the PMI; and \n at least one output, coupled to the control circuitry, which, in operation, outputs the pre-coded data for transmission via the multi-antenna array to the terminal apparatus.
