An HSDPA-compatible mobile terminal comprises a first measurement unit that measures the CPICH reception quality, a second measurement unit that measures the HS-PDSCH reception quality, a control unit that exerts control, depending on the reception environment, to either generate the CQI information using, primarily, the measurement results in the first measurement unit, or to generate the CQI in the first measurement unit, or to generate the CQI information using, primarily, the measurement results in the second measurement unit, and a transmission unit for transmitting said CQI information to a ground base station.
