Abstract  Abstract

A channel quality information transmission method based on a differential method is started. According to the present invention, when transmitting channel quality information for a predetermined number of subbands selected by a receiving end in a frequency selective channel, the entire average channel information is transmitted, and the selected predetermined number of subbands is transmitted. Is transmitted in the form of subband difference information with respect to the average channel information, and at this time, the subband difference information can be represented in the form of a specific value within a difference value range having only positive values. In addition, when two or more channel quality information is transmitted in a multi-antenna system, channel quality information for one channel is transmitted, and channel quality information for another channel is transmitted in the form of spatial difference information. The information can be transmitted in the form of a specific value within a difference value range that is set to have a range that is not symmetrical about zero. (Selection) Figure 7
