ABSTRACT:
Channel quality estimating section104estimates the channel quality from the reception signal quality and outputs the result to transmission method determining section105and control signal dividing section108. Transmission method determining section105determines a transmission method of a signal transmitted to communication partner from channel conditions and outputs the result to switch106, switch107and control signal dividing section108. Control signal dividing section108divides the transmission method information into high-speed control signal which is transmitted periodically and low-speed control signal which is transmitted on demand rather than periodically. Moreover, control signal dividing section108determines the combinations of low-speed control signal and high-speed control signal outputted from a tendency of communication quality, and outputs the result to modulator114. Modulator114modulates the high-speed control signal and low-speed control signal, and outputs the result to multiplexer115.
