A method of transmitting a channel quality indicator (CQI) includes obtaining CQIs for each of a plurality of sub-bands, a sub-band comprising a plurality of sub-carriers, dividing the plurality of sub-bands into a plurality of layers according to a CQI of a sub-band, a layer comprising at least one sub-band, obtaining a representative value of a representative layer, the representative layer including a sub-band having maximum CQI and transmitting the representative value of the representative layer. Signaling overhead due to CQI feedback can be reduced.
