Abstract: A mobile station, and corresponding system and method, the mobile station including an IQ multiplexer configured to IQ multiplex transmission data for data channels, control data for a control channel, and control data for an exclusive control channel for high speed downlink packet data, and to generate a complex signal; and a transmitter configured to modulate and transmit the complex signal generated by the IQ multiplexer. The IQ multiplexer assigns the transmission data for the data channel to the I axis and the Q axis, alternately, and assigns control data to the Q axis. When control data for high speed downlink packet data are added, the IQ multiplexer assigns the control data for high speed downlink packet data to the Q axis when a set number for the data channel is an odd number and to the I axis when the set number is an even number.

Abstract: It aims at suppressing power consumption of a transmission system amplifier and increasing a communication time period by controlling operation characteristics of the transmission system amplifier, based on a maximum transmission power value required at a transmission position of the mobile station 100. The base station 900 monitors the transmission position and reception quality of the mobile station 100. The maximum transmission power required at the transmission position is calculated by statistics processing or prediction. Based on this, the mobile station 100 controls the operation characteristics of the amplifier in order to output the required maximum transmission power.
