    摘要: A method for transmitting channel quality information based on a differential scheme is disclosed. When channel quality information of a predetermined number of sub-bands selected by a receiver in a frequency selective channel is transmitted, total average channel information is transmitted. Channel information of the selected sub-bands is transmitted as sub-band differential information associated with average channel information. In this case, the sub-band differential information may be denoted by a specific value contained in a differential-value range including only positive (+) values. If at least two channel quality information is transmitted by a MIMO system, channel quality information of one channel is transmitted, then channel quality information of the other channel is transmitted as spatial differential information. In this case, the spatial differential information is denoted by a specific value contained in a differential-value range asymmetrical on the basis of “0”.

    摘要: A method of generating and transmitting a channel quality indicator is disclosed, by which a feedback size of channel quality information is reduced. The present invention includes selecting at least one subband by considering a channel quality of each of entire subbands formed by grouping a predetermined number of subcarriers, additionally selecting subbands adjacent to the at least one subband selected in the first selection step, and generating the channel quality indicator corresponding to the subbands selected in the first selection step and the second selection step.
