Mobile station, base station, communication system, and communication method
First Claim
1. In an IQ multiplexing method of IQ multiplexing transmission data for a data channel, control data for a control channel and control data for an exclusive control channel for high speed downlink packet data, of generating a complex signal, the improvement comprising:
- assigning transmission data for a data channel alternately to I-axis and Q-axis and assigning to I-axis at first,assigning control data for a control channel to Q-axis,assigning control data for an exclusive control channel for high speed downlink packet data, to a Q axis when a set number for the data channel is an odd number, and to an I axis when an even number, andscrambling the data of each channel after the IQ-multiplexed one for the data of each channel.

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.
