FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a wireless communication mobile station device. In said device, a group control unit (107) controls a group of subcarriers from a plurality of subcarrier groups, the CQI of which is to be reported, in order to periodically change the group according to pattern information. For example, the group control unit (107) changes the group of subcarriers, the CQI of which is to be reported based on a frame or a transmission time interval (TTI). Furthermore, the group control unit (107) sets a group of subcarriers, the CQI of which is to be reported, to a SINR determining unit (108) and a CQI generating unit (109).
EFFECT: high throughput during multi-carrier communication.
