Kind Code:

A1

Abstract:

[PROBLEMS] To perform a scheduling for improving the throughput, while suppressing the amount of control information notified from a communication terminal apparatus. [MEANS FOR SOLVING PROBLEMS] A communication terminal apparatus (200), which communicates with a communication control apparatus (100), comprises a receiving part (220) that receives a control signal from the communication control apparatus; a reception quality measuring part (250) that measures the reception quality of each of channels; a reception quality information generating part (260) that selects, based on the received control signal and the results of reception quality measurements, some of the channels as selection channels and further generates reception quality information for notifying a communication destination apparatus of both selection channel information used for identifying the selected selection channels and the results of reception quality measurements of the selected selection channels; and a transmitting part (290) that transmits the generated reception quality information to the communication control apparatus. The receiving part (220) receives from the communication control apparatus (100) a data signal assigned to at least one channel included in the selection channels.
