Optimizing power consumption of a base station

A base station apparatus, the base station apparatus being located in a cell of a mobile telecommunication network, wherein the base station apparatus comprises:

• an amplifier for amplifying signals;
• an antenna for transmitting the amplified signals and for receiving signals;
• a processor adapted to:
• determine if the traffic load is lower than a first traffic load threshold;
• decrease a maximum used output load of the amplifier of the base station, if the traffic load is lower than the first traffic load threshold;
• adjust an operation point of the amplifier, if the traffic load is lower than the first traffic load threshold;
• determine if the traffic load is higher than a second traffic load threshold;
• increase the maximum used output load of the amplifier, if the traffic load is higher than the second traffic load threshold;
• and
• adjust the operation point of the amplifier, if the traffic load is higher than the second traffic load threshold;
• and
• a timer, the timer defining a time, wherein the timer is started directly after having decreased or increased the output load of the amplifier, and wherein a further increasing or decreasing of the output load is disabled during the time defined by the timer.

A non-transitory computer-readable storage medium comprising instructions that when executed by a base station apparatus cause the base station apparatus to perform a method of communicating in a cell of a mobile telecommunication network, wherein at least one resource is divided into a plurality of resource blocks, the resource blocks being used for scheduling data transmissions in said telecommunication network, wherein the method comprises:

• measuring a traffic load in the cell;
• determining, if the traffic load is lower than a first traffic load threshold;
• decreasing a maximum used output load of an amplifier of the base station, if the traffic load is lower than the first traffic load threshold, wherein the amplifier amplifies signals being transmitted by the base station;
• adjusting an operation point of the amplifier, if the traffic load is lower than the first traffic load threshold;
• determining, if the traffic load is higher than a second traffic load threshold;
• increasing the maximum used output load of the amplifier of the base station, if the traffic load is higher than the second traffic load threshold;
• adjusting the operation point of the amplifier, if the traffic load is higher than the second traffic load threshold;
• and
• defining a time by a timer, wherein the timer is started directly after having decreased or increased the output load of the amplifier, and wherein a further increasing or decreasing of the output load is disabled during the time defined by the timer.
