Abstract  Abstract

The invention claims a method for transmitting channel quality information based on a differential scheme. When the channel quality information of a pre-determined number of sub-bands selected by a receiver in a frequency selective channel is transmitted the total average channel information is transmitted. Channel information of the selected sub-bands is transmitted as sub-band differential information associated with the 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 pieces of channel quality information are transmitted by an MIMO system the channel quality information of one channel is transmitted and then the 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.
