Energy-Aware Configuration Of Small Cell Networks

We propose a new approach for jointly scheduling deep sleep and allocating pilot and data transmit power in small cells with the aim of minimising energy consumption while maximising user utility within a mixed macro/small cell network. Our approach exploits the relatively predictable nature of traffic load across each day/week and is demonstrated to achieve an average energy reduction of 37 %, and peak energy reductions of 70 % under realistic traffic loads and network topologies.
