Provided is a wireless communication mobile station device by which a throughput can be improved in multicarrier communication. In the device, a group control section (107) controls a subcarrier group, of which CQI is to be reported, among a plurality of subcarrier groups to periodically change, by following pattern information. For instance, the group control section (107) changes the subcarrier group whose CQI is to be reported, by frame or TTI (Transmission Time Interval). Furthermore, the group control section (107) specifies the subcarrier group whose CQI is to be reported, to an SINR detecting section (108) and a CQI generating section (109).
