Patent ID: 8599942

Claim:
A receiving device, comprising: received power control means for controlling a received power of a communication signal transmitted from a base station via at least one of subchannels according to an orthogonal frequency division multiple access system, depending on a maximum received power of a signal received together with the communication signal via any of the subchannels; and modulation and coding scheme determining means for determining a modulation and coding scheme for a new communication signal to be transmitted from the base station, based on signal quality of the communication signal subjected to the received power controlled by the received power control means, the receiving device for requesting the base station to transmit the new communication signal, using the modulation and coding scheme determined by the modulation and coding scheme determining means, the receiving device further comprising: received power difference detecting means for detecting a received power difference between the maximum received power of the signal transmitted from the base station and a maximum received power of a signal arriving from a device different from the base station, wherein the modulation and coding scheme determining means determines the modulation and coding scheme of the new communication signal, based further on the received power difference detected by the received power difference detecting means.
