Abstract
A method and apparatus for efficiently transmitting data in an MIMO communication system are provided. The method includes receiving first Channel State Information (CSI) fed back from a plurality of terminals; requesting feedback of 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.
