Abstract
The mobile communication terminal of the present invention comprises an amplitude regulatorregulating the amplitudes of signals of the DPDCH, DPCCH, and HS-DPCCH, a transmission-power controllercontrolling the power-distribution ratio for the adjustment of transmission power of the individual transmission channels, and a priority-channel selectorchoosing a priority channel from among the individual transmission channels. If the total transmission power of the individual transmission channels is going to exceed the maximum transmission power, the transmission-power controllerdetermines the power-distribution ratio among the individual transmission channels by adjusting the transmission power of the priority transmission channel to a power level demanded by a base station on the one hand and adjusting the transmission power of the non-priority channel so as to confine the total transmission power to the maximum transmission power on the other hand. Accordingly, the base station can receive information correctly even if the transmission power demanded by the base station is beyond the maximum transmission power of the mobile communication terminal.
