Abstract:
The present invention relates to a method for feeding back, by a terminal, channel status information (CSI) in a wireless communication system. In detail, the method includes the steps of feeding back a subband channel quality indication (CQI) and a subband precoding matrix index (PMI), wherein a first subband size for the subband CQI and a second subband size for the subband PMI are set differently.
