FIELD: information technology.
SUBSTANCE: in the device, data selection is used to schedule according to data type, at that for transmission it is determined whether to transmit Channel Quality Indicators (CQI) for each of all subcarrier blocks in communication frequency band or to transmit CQI indicating receive quality averaged by all subcarrier blocks in communication frequency band on the basis of control information included in the received signal, and CQI for each of all subcarrier blocks in communication frequency band or CQI indicating channel quality averaged by all subcarrier blocks in communication frequency band on the basis of determination.
EFFECT: higher transmission efficiency, achieving low power consumption and high speed of signal processing.
