A multicarrier communication method capable of improving the frequency utilization efficiency and the throughput of the communication system, while satisfying the QoS. A communication terminal reports the CQI about all of the subchannels included in the bandwidth of a communication channel during a first CQI report, as shown in the upper figure portion. Unlike the first report, during the second and following CQI reports, in which much time is left in terms of the permissible delay time, the communication terminal reports the CQI only about subchannels 1 and 2 assigned by the second and following frequency assignments, as shown in the lower figure portion.
