Abstract:
A method for feeding back a Channel Quality Indicator (CQI) in a mobile communication system is provided. The method includes determining a number of subchannels for which the MS feeds back CQIs based on a preset feedback efficiency factor, selecting the determined number of subchannels in a descending order of channel quality, and feeding back the CQIs of the selected subchannels to a Base Station (BS).
