Abstract
Provided is a method for transmitting and receiving a channel quality indicator (CQI) in a multi carrier wireless system which does not increase load while efficiently feeding back a change of the channel quality. The method for transmitting the channel quality indicator in a Orthogonal Frequency Division Multiple Access (OFDMA)-based terminal, includes the steps of: a) transmitting a first report indicator requesting transmission of a measured channel quality indicator to a base station through a control channel when a change range of a channel quality indicator is greater than a predetermined threshold value; and b) transmitting the measured channel quality indicator to the base station through allocated radio resources when a response to the first report indicator is received from the base station.
