<P>PROBLEM TO BE SOLVED: To solve a problem that when a reception power value deviates from an appropriate value, degradation in reception characteristics arises both in the cases that the reception power value is too high and that it is too low in radio communication equipment. <P>SOLUTION: The control of the gain of a reception circuit on the basis of the result of the determination of the quality of a reception signal in a signal processing circuit, and the control of the transmission power of a transmission circuit and of the gain of the reception circuit by using a transmission power control signal included in the reception signal are performed collectively. By performing the controls, the optimum operation of the transmission power of a radio communication system and reception characteristics in demodulating the reception signal is obtained. Furthermore, as the result of the optimum operation, the power consumption of the entire radio communication equipment is reduced by avoiding the excessive consumption of power consumed in the reception circuit, power consumed in the signal processing circuit, and power consumed in the transmission circuit. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
