A radio base station that measures a reception power of a downlink radio signal transmitted for a first radio area and controls a transmission power for a radio resource assigned to a downlink radio signal to be transmitted for a second radio area according to the measured reception power, the radio resource including a plurality of resource units obtained by dividing the radio resource in a frequency domain, the control being performed by increasing a per-unit transmission power that is a transmission power per resource unit and decreasing a number of the resource units assigned to the downlink radio signal.
A method for controlling a transmission power in a radio base station, the method comprising:
- measuring a reception power of a downlink radio signal transmitted for a first radio area;
- and
- controlling a transmission power for a radio resource assigned to a downlink radio signal to be transmitted for a second radio area according to the measured reception power, the radio resource including a plurality of resource units obtained by dividing the radio resource in a frequency domain, the control being performed by increasing a per-unit transmission power that is a transmission power per resource unit and decreasing a number of the resource units assigned to the downlink radio signal.
