Base station power model and application for energy efficient LTE

Long Term Evolution (LTE) and LTE-A researchers are deploying variety of techniques such as Multiple Inputs Multiple Outputs (MIMO) to achieve the higher throughput, while paying little attention to power consumption. In this paper, meticulous base station power consumption model is proposed, while more significantly, the model is calibrated. Then the relations between system parameters and power consumption of each sub-components is established, this energy consumption model and LTE system level simulation platform are integrated as a system level power consumption simulation platform. Two different base station energy saving technology applications are verified. Result shows 1.7 times EE improvement on average day utilizing the two schemes, while maximum EE increase per hour is 4.3 times.
