Abstract
Disclosed is a method whereby a channel quality indicator is fed back by a terminal in a multiple-antenna wireless communication system. More specifically the method comprises the steps of: receiving reference signals corresponding to a plurality of data streams from a base station; using the reference signals to calculate a channel quality indicator; and transmitting the calculated channel quality indicator to the base station; and in the step in which the channel quality indicator is calculated the channel quality indicator is calculated under the assumption that at least one of the reference signals has been transmitted using either the spatial-multiplexing technique or the transmission diversity technique depending on the feedback setting of the terminal.
