Abstract
There is provided mechanisms for controlling total average transmission power of a radio base station. A method is performed by a control device. The method comprises performing control of total average transmission power (Ptot)(t) of the radio base station according to a back-off power control loop. In the back-off power control loop, a setpoint value (Ptot)ref of the total average transmission power is compared with a value of the total average transmission power (Ptot)(t)—The value of the total average transmission power (Ptot)(t) is computed over an averaging time T. Control parameters of the back-off power control loop are scaled proportionally to the inverse of the averaging time T. The control parameters pertain to a response time of the back-off power control loop.
