LTE-A异构网的能效仿真研究

With the rapid growth of mobile communication industry, increasingly importance has been attached to the associated energy consumption issue of the radio access network.Heterogeneous networks (HetNets) are expected to reduce the energy consumption and maintain the system capacity with deploying dense low power Pico nodes. This paper investigate the energy efficiency gains of HetNets with introducing ABS-based eICIC scheme. First, based on the power consumption models, we analyize the system capacity and give the performance metric. A HetNets system-level simulation platform is built and we evaluate the effect of the different deployment of HetNets and eICIC configurations. The results shows that the system energy efficiency is significantly improved and simultaneously the users` QoS is maintained with proper deployment and eICIC configuration.
