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, for a current discrete time value t, control of total average transmission power {P}(t) of the radio base station according to a back-off power control loop. The total average transmission power {P}(t) is computed over an averaging time window T of the present value of momentary transmission power and the N−1 values of momentary transmission power preceding the present value of momentary transmission power. The method comprises evaluating, for a future discrete time value less than, or equal to, t+T, the total average transmission power, assuming that values of momentary transmission power for all discrete time values from t up to t+T, starting at the next discrete time value t+1, is limited to a minimum value of said momentary transmission power. The method comprises limiting the momentary transmission power to the minimum value for at least the next future discrete time value when the evaluated total average transmission power, for any of the future discrete time values, exceeds a power threshold value based on a regulatory limit.
