CODEBOOK FOR LARGE-SCALE MIMO SYSTEMS AND COMMUNICATION METHOD AND APPARATUS USING THE SAME

摘要

The embodiment of the present invention provides a kind of reduction feedback overhead, and when quantization and feeding back channel state information is from multi-input multi-output system. It is a kind of for operating the multi-input multi-output system of receiver according to one embodiment, include the following steps: to execute Trellis coding quantization receiving channel information by using selecting multiple code books in code book; And having sent feeding information includes that quantized result is sent to transmitter. It include processing truncation receiving channel information in the receiving channel information for executing Trellis coding quantization include that code word in selected code book is converted into the groups of multiple code words of multiple groups multichannel vector sum and is respectively connected with; The each channel vector for row format structural type coded quantization group of going forward side by side is because utilize each code word of group. ;The 2015 of copyright KIPO submissions
