A communication terminal apparatus that can eliminate the waste of reception quality report, suppress the interference of an upstream network, perform an optimum assignment using a scheduling, prevent the loss of resources, and ensure the fairness of transmission assignment using the scheduling. In this apparatus, a reception quality determining part (110) uses a pilot signal, which is included in a received signal, to determine the reception quality for each of subcarrier blocks. A CQI generating part (111) generates CQIs each of which is the information indicative of a result of the determination by the reception quality determining part (110). A sorting part (112) sorts the CQIs in descending or ascending order of the reception quality. A control part (113) instructs, based on information about the number of subcarrier blocks in which the CQIs have been transmitted, collision information and scheduling information, the sorting part (112) with respect to the number of subcarrier blocks in which the CQIs are outputted.
