A mobile device includes a first receiving unit that receives a dedicated pilot signal included in a dedicated pilot signal part of a data unit that is transmitted from a base station to the self-device, an second receiving unit that receives a signal included in a dedicated pilot signal part of a data unit that is transmitted from the base station to the other device other than the self-device, a CQI generating unit that estimates a channel quality indicator that indicates a reception environment when the self-device receives data on the basis of the dedicated pilot signal received by the first receiving unit and the signal received by the second receiving unit, and a radio unit that transmits the channel quality indicator estimated by the CQI generating unit to the base station. Therefore, the present invention can contribute to the assignment optimization of a radio resource of the base station.
