Abstract:
There is provided a method for transmitting channel quality information in a wireless communication system. Over-all band of the wireless communication system is divided by a plurality of sub-bands. The method includes selecting a first sub-band having the highest CQI among the plurality of sub-bands, transmitting CQI of the first sub-band and transmitting CQI of a second sub-band, the second sub-band having the CQI lower than the first sub-band, wherein the number of CQI levels of the second sub-band is less than that of CQI levels of the first sub-band. Overheads incurred by CQI feedback can be reduced.
