A power control bit inserting method between a base station and a terminal. The base station and the terminal each use a plurality of adjacent frequency bands as signal paths with independent signal paths of a real part and an imaginary part given to each frequency. In the power control bit inserting method, a unit time is set to a power control group period, n-bit data is allocated to each signal path, the power control group period is divided by the number of signal paths, and a power control bit is inserted in each divided segment, so that the insertion positions in the real and imaginary parts of each frequency are spaced from each other by n/2 bit and the start position of the real signal path of each frequency is inserted at an appointed bit position of the corresponding frequency.
