1. A transmission method, comprising the steps ofgenerating a complex signal by IQ multiplexing transmission data for a data channel and control data for a control channel;
- andmodulating the complex signal generated in the IQ multiplexing and transmitting the modulated complex signal, whereinwhen control data for a control channel are added, the control data to be added are assigned to the I axis or the Q axis according to a set number for the data channel in the IQ multiplexing.

Abstract
A scrambler performs IQ multiplexing of output signals from a spreader and a distributor in order to generate a complex signal (I signal and Q signal), amplitude coefficients βcc(I) and βcc(Q) are determined in accordance with signal powers on I axis and Q axis.
