Title:
CODEBOOK FOR MULTIPLE-INPUT MULTIPLE-OUTPUT SYSTEM AND COMMUNICATION METHOD AND DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/093918
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a scheme for reducing feedback overhead when quantizing and feeding back channel state information in a multiple-input multiple-output (MIMO) system. A method for operating a receiver in a MIMO system, according to one embodiment of the present invention, comprises the steps of: performing Trellis coded quantization for received channel information by using a codebook selected from a plurality of codebooks; and transmitting, to a transmitter, feedback information including the quantization result. The step of performing Trellis coded quantization for the received channel information comprises a step of truncating the received channel information and codewords included in the selected codebook into multiple groups of channel vectors and multiple groups of codewords, respectively, and performing Trellis coded quantization for each of the groups of channel vectors by using each of the groups of codewords.
