Transmission power control for a radio base station

A control device for controlling total average transmission power Ptot(t) of a radio base station over a fixed time period, the control device comprising:

• processing circuitry;
• and
• a memory comprising instructions which, when executed by the processing circuitry, cause the control device to:
• obtain values of average total transmission power of at least one previous transmission from the radio base station;
• determine a resource factor value y(t) from the value of average total transmission power and a setpoint value Ptotref of the average total transmission power Ptot(t), by calculating δ2Pmax,site≤Ptotref≤δ1Pmax,site, where Pmax,site denotes maximum transmission power of the radio base station, δ1 and δ2 are set threshold values, and γ(t) is set to 1 at δ1Pmax,site;
• determine, based on the resource factor value y(t), an action that restricts an amount of code-division multiple access (CDMA) resources to be used at least for a current transmission;
• and
• control the total average transmission power over the fixed time period by initiating enabling of the determined action at least for the current transmission when Ptot(t)>δ1Pmax,site and disabling the determined action when Ptot(t)<δ2Pmax,site.

A non-transitory machine readable storage medium comprising computer code which, when run on a processing circuitry of a control device, causes the control device to perform operations to control total average transmission power Ptot(t) of a radio base station over a fixed time period by performing operations comprising:

• obtaining values of average total transmission power of at least one previous transmission from the radio base station;
• determining a resource factor value y(t) from the value of average total transmission power and a setpoint value Ptotref of the average total transmission power Ptot(t), by calculating δ2Pmax,site≤Ptotref≤δ1Pmax,site, where Pmax,site denotes maximum transmission power of the radio base station, δ1 and δ2 are set threshold values, and γ(t) is set to 1 at δ1Pmax,site;
• determining, based on the resource factor value y(t), an action that restricts an amount of code-division multiple access (CDMA) resources to be used at least for a current transmission;
• and
• controlling the total average transmission power over the fixed time period by initiating enabling of the determined action at least for the current transmission when Ptot(t)>δ1Pmax,site and disabling the determined action when Ptot(t)<δ2Pmax,site.
