摘要： There is provided a wireless communication apparatus which achieves high efficiency in power use in such a manner that transmission power is adequately distributed in simultaneous transmission to multiple base stations. The wireless communication apparatus provided by the present invention, at the same time, transmits a first data signal to a first base station apparatus by using a first CC and transmits a second data signal to a second base station apparatus by using a second CC. The wireless communication apparatus includes a transmission-power controller that scales transmission power by using different scaling factors for the first data signal and the second data signal, when the sum of transmission power of the first data signal and transmission power of the second data signal is larger than a predetermined value. The transmission power of the first data signal is calculated to obtain predetermined reception power in the first base station apparatus. The transmission power of the second data signal is calculated to obtain predetermined reception power in the second base station apparatus.
