Abstract
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.

9. A radio communication apparatus comprising:
-
an assigning section that assigns a subchannel to a communicating party based on a channel quality indicator reported from the communicating party; a deciding section that decides time left in an allowable delay time for data transmitted from the communicating party; and a commanding section that designates a channel quality indicator report method matching the time left to the communicating party, as a channel quality indicator report method with respect to the subchannel. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
