Abstract
Official abstract text for this publication.
The present description relates to a method of using a terminal to adaptively feed back channel information relating to multi-cell cooperative communication includes: measuring an average signal-to-noise ratio of a virtual multi-antenna channel between a terminal and at least one cell to transmit same to a base station; receiving, from a base station, a number of allowable feedback bits determined on the basis of the average signal-to-noise ratio and cooperative communication information; selecting a codebook from a plurality of predetermined codebooks on the basis of the number of allowable feedback bits and the cooperative communication information; and quantizing channel information on a virtual multi-antenna channel using the selected codebook, and transmitting feedback information including the quantized channel information to a base station. The codebook may be selected to transmit the feedback information using the entire number of allowable feedback bits.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of adaptively feeding back, by a terminal, channel information relating to multi-cell cooperative communication, the method comprising: measuring average signal-to-noise ratio of virtual multi-antenna channels between the terminal and one or more cell, the average signal-to-noise ratio being transmitted to a base station; receiving, from the base station, a number of allowable feedback bits and cooperative communication information determine…
