In wireless access networks the traffic load varies strongly along a day and efficient concepts to adapt the power consumption of LTE macro base stations to the required traffic load are currently widely under study. Significant daily energy savings up to 35% can be achieved for different deployment scenarios by introducing energy adaptive hardware features in combination with energy aware scheduling...
In today's macro base stations, the transceiver system is one of the most power-consuming components, simply due to low energy efficiency of the power amplifier. The decreased performance in medium and low load situations gives significant room for energy saving. For exploiting this potential, different concepts are proposed by the EARTH project to mitigate the energy wastage in transceiver systems...
