Abstract :
As energy saving becomes a major concern in LTE, we propose a novel energy saving approach with interference reduction enhancement in LTE. Firstly, new power model is introduced in energy saving gain analysis. Then three categories of symbol level PA shutdown schemes are analyzed and their performance is also evaluated quantitatively. In the end, a comprehensive strategy is proposed, simulation results show that it can achieve 15-20% energy gain and keep throughput at a reasonable level. It can be applied in current LTE network.
