  • Base station device, control station device, and transmission power control method
    Patent number: 7054655
    Abstract: A total-transmission-power measurement section 113 measures a total-transmission-power-value output from a transmitting RF circuit 112, and outputs the measured value to a total-transmission-power comparison section 152. A reference-total-transmission-power setting section 151 outputs a reference total-transmission-power-value, which is a target of the total-transmission-power-value of a base station, to the total-transmission-power comparison section 152. The total-transmission-power comparison section 152 outputs instructions to reduce allowable transmission-power-values to allowable-transmission-power setting sections 153 of users 1–n, when a value obtained by subtracting of the reference total-transmission-power-value, which has been input from the reference-total-transmission-power setting section 151, from the total-transmission-power-value input from the total-transmission-power measurement section 113 exceeds a predetermined value.
