Abstract

Extensive deployment of LTE cellular networks can enhance network throughput via the shared spectrum utilization; however, the energy efficiency is largely ignored during the current spectral efficiency maximization, which is especially important in large-scale LTE networks. By now, we know that green communications and energy efficiency are important for the future sustainable 5G networks. Power control can improve both spectral efficiency and energy efficiency. In this paper, a distributed power control method is investigated for LTE uplink, which is based on the formulation and analysis of a defined cooperative game theoretic power control framework. A novel utility function is designed with the energy efficiency into consideration. Furthermore, the location-aware weighted bargaining game theory is formulated with a denoted balancing factor. Finally, simulation results show that the presented algorithm is with a fast convergence rate. Meanwhile, it can ensure the SINR of all users with reducing power consumption, therefore, improve energy efficiency.
