DATA TRANSMISSION METHOD AND APPARATUS IN MIMO COMMUNICATION SYSTEM

摘要

A method and apparatus for efficiently transmitting data in an MIMO communication system are provided. The method comprises receiving a first Channel State Information (CSI) fed back from a plurality of terminals, respectively: requesting feedback of a second CSI from the respective terminals, the second CSI differing from the first CSI; and determining the terminals to be grouped by using at least one of the first CSI and second CSI, when the second CSI is fed back from the respective terminals.
