Method and apparatus for transmitting/receiving channel quality information in a communication system using orthogonal frequency division multiplexing scheme, and system thereof

The present invention relates to a method and apparatus for transmitting and receiving channel quality information (CQI) for subcarriers between a terminal (MSS) and a base station in a communication system using an orthogonal frequency division multiplexing. UE to about bands each consisting of sub-carriers adjacent to the predetermined number of measuring channel quality information (CQI) value, corresponding to the CQI measured value is selected at least two bands, and, in the selected band to transmit information about the differential CQI indicating a change of the CQI measurement to the base station. The present invention, while having the least amount of signaling overhead, so that CQI is reflected in real time for each frame. CQICH, subchannel allocation, band, throughout CQI, the differential CQI
