Abstract:
1. A communication terminal apparatus comprising: a reporting unit that is configured to report a channel quality indicator (CQI) to a base station; a counting unit that is configured to count a number of times the reporting unit has reported the CQI; a receiving unit that is configured to receive allocation information from the base station; an accumulating unit that is configured to accumulate a number of subcarrier blocks that have been allocated to the communication terminal by the base station; a calculating unit that is configured to calculate a cumulative allocation rate based on the counted number of times and the accumulated number of subcarrier blocks; and a controlling unit that is configured to increase a number of subcarrier blocks for which the CQI is to be reported when the calculated cumulative allocation rate is lower than a threshold, and to decrease the number of subcarrier blocks for which the CQI is to be reported when the calculated cumulative allocation rate is higher than the threshold.
