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.
