A METHOD FOR ADAPTIVE FEEDBACK AND ADAPTIVE TRANSMISSION MODE DETERMINATION FOR MULTI-CELL COOPERATIVE TRANSMISSION AND AN APPRATUS FOR THE SAME

摘要

The present invention more particularly pertains to a wireless communication system, is the adaptive feedback and adaptive transmission mode decision method and apparatus for a multi-cell cooperative communication is disclosed. The present day method for the UE feeding back the channel information to adaptively for a multi-cell cooperative communication according to the embodiment of the invention, wherein by measuring the terminal and the average signal-to-noise ratio between the one or more cells and a virtual multiple-antenna channel for transmitting to the base station step; From the base station receiving a number of allowed feedback bits and cooperative communication information determined based on the average signal-to-noise ratio; Comprising, based on the number of allowed feedback bits and the cooperative communication information, selecting a codebook from among a plurality of codebooks defined in advance; And said using the selected codebook to quantize the channel information for the virtual multiple-antenna channel, and transmitting the feedback information including the quantized channel information to the base station, and wherein the codebook is the number of the allowed feedback bits using both may be selected to transmit the feedback information.
