Abstract
A controller of a private base station receives data on a travel time depending on a propagation delay between a private base station and a user terminal. The controller outputs a control signal to a controllable amplifier for decreasing a transmission power of the private base station if the measured travel time is longer than a predetermined reference time or quality of service is lower than reference quality.
