Controlling total average transmission power of a radio base station

A control device for controlling total average transmission power of a radio base station, the control device comprising:

• processing circuitry, the processing circuitry being configured to cause the control device to:
• perform, for a current discrete time value t, control of total average transmission power of the radio base station according to an average power control loop and subject to an upper average power threshold value that is based on a computed exclusion zone,
• wherein the total average transmission power is computed over an averaging time window T of a present value of momentary transmission power and N−1 values of momentary transmission power preceding the present value of momentary transmission power,
• wherein the total average transmission power in the average power control loop is controlled to not exceed the upper average power threshold value by a resource threshold factor that limits the momentary transmission power and by for at least one future discrete time value less than, or equal to, t+T predicting a future value of the total average transmission power for a future assumed resource threshold factor;
• and
• gradually change the resource threshold factor as a function of a present state of the average power control loop, wherein the present state at least pertains to the total average transmission power.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause a control device to control average transmission power of a radio base station by performing operations comprising:

• performing, for a current discrete time value t, control of total average transmission power of the radio base station according to an average power control loop and subject to an upper average power threshold value that is based on a computed exclusion zone,
• wherein the total average transmission power is computed over an averaging time window T of a present value of momentary transmission power and N−1 values of momentary transmission power preceding the present value of momentary transmission power,
• wherein the total average transmission power in the average power control loop is controlled to not exceed the upper average power threshold value by a resource threshold factor that limits the momentary transmission power and by for at least one future discrete time value less than, or equal to, t+T predicting a future value of the total average transmission power for a future assumed resource threshold factor;
• and
• gradually changing the resource threshold factor as a function of a present state of the average power control loop, wherein the present state at least pertains to the total average transmission power.
