Patent ID: 8855131

Claim:
A transmission apparatus that uses a first mode for allocating transmission data to a contiguous frequency band and a second mode for dividing the transmission data into a plurality of clusters and allocating the plurality of clusters to non-contiguous frequency bands, the apparatus comprising: a control section configured to control a transmission power of the transmission data in accordance with the first mode or the second mode; and a transmission section configured to transmit the transmission data at the transmission power, wherein in the first mode, the control section sets the transmission power based on a transmission power control method set for the contiguous frequency band and, in the second mode, the control section sets a bandwidth of a first frequency band, which is derived from a lowest frequency in a cluster allocated to a lowest frequency band among the plurality of clusters and a highest frequency in a cluster allocated to a highest frequency band among the plurality of clusters, as a bandwidth of the contiguous frequency band in the first mode, and calculates a first power based on the set bandwidth of the contiguous frequency band and the transmission power control method, and the control section calculates the transmission power, using the first power and a ratio between the bandwidth of the first frequency band and a bandwidth of a second frequency band that includes the non-contiguous frequency bands to which the plurality of clusters are allocated.
