    摘要: A method and apparatus for transmitting/receiving feedback information in a multi-user multi-antenna system and a system supporting the same are provided, in which all possible combinations are created using column vectors included in a precoding codebook, column vectors are correlated in each of the combinations, column vectors comprising correlations exceeding a reference threshold are designated as similar vectors, at least two similar vector sets are formed with the similar vectors, and feedback information is generated based on the at least two similar vector sets and transmitted.
