Green resource allocation in LTE system for unbalanced low load networks

In Long Term Evolution (LTE) networks, Energy-Efficient (EE) and Mobility Load Balancing (MLB) are two important functions to optimize the network performance. In order to deal with the energy consumption in downlink LTE system for unbalanced low load scenarios, we built an effective EE resource allocation optimization model and employed a low complexity method to achieve the goal of the optimization in this paper, named EE-VBEM. Simulation results show that EE-VBEM can reduce the overall downlink energy consumption significantly and enhance the spectrum efficiency effectively in unbalanced low load networks.
