摘要
随着无线通信技术的发展,异构网络融合已成为下一代网络的发展趋势,用户-网络关联是无线资源管理的研究热点之一。用户-网络关联是指用户在异构网络中,根据性能指标选择最佳接入基站或接入点。研究大规模MIMO异构网络中基于能效和公平的用户-网络关联算法,以最大化系统能效为目标建立优化模型,提出一种基于一对多匹配博弈的用户-网络关联算法,并证明了该算法的收敛性和稳定性。通过仿真分析验证了该算法的能效和公平均衡能力。
With the development of wireless communication technology,heterogeneous network convergence has become the development trend of next generation network. User-cell association is one of the research hotspots of radio resource management,which means users select the best base station（ BS） or access point（ AP） according to the performance index in the heterogeneous network. In this paper,user-cell association algorithm is focused on energy efficiency and user fairness in massive MIMO heterogeneous networks. The mathematical model of optimization issue is established with the objective of maximizing system energy efficiency. A user-cell association algorithm is proposed based on one to many matching game,and the convergence and stability of proposed algorithm is proved. The simulation analysis of the performance proves the energy efficiency and user fairness of the proposed algorithm.
