摘　　要：为了响应国家绿色网络的号召,提出了一个在5G混合网络中基于TDMA的联合考虑用户关联和功率控制的能效优化方案。以基站最大关联用户数为约束条件、最大化系统能效为目标设计用户关联算法,根据已知的用户关联算法利用Dinkelbach算法和凸优化工具箱优化功率控制。通过用户关联和功率控制的交替迭代优化获得系统最大能效。对提出的交替优化算法进行了仿真分析,进一步验证了所提优化方案具有较好的能效性能。In order to respond to the green network,this paper proposes an energy efficiency optimization scheme based on TDMA system by jointly optimizing user association and power control in5G hybrid network.With the goal of maximizing the energy efficiency of the system and the constraint condition of the maximum quantity of user associated with a base station,the association algorithm is designed.Based on the known user association,the Dinkelbach algorithm and the convex optimization toolbox are used to optimize the power control.The maximum energy efficiency is achieved through the alternate iteration optimization of user association and power control.Finally,the proposed the algorithm is simulated and analyzed,and the simulation results show the proposed algorithm has better energy efficiency performance.
