Abstract  Abstract

A channel quality information transmission method based on a difference scheme is disclosed. According to the present invention, when transmitting a channel quality information for a predetermined number of subbands selected by a receiver in a frequency selective channel, the UE transmits total average channel information, and the channel information for the selected predetermined number of subbands is divided into subbands And the subband difference information may be expressed in the form of a specific value within a differential value range having only a positive value. In the case of transmitting two or more channel quality information 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. At this time, In the form of a specific value within a difference value range set to have a range that is not symmetric with respect to 0 as a center.
