摘　　要：为解决基站数十亿通信设备的通信能耗和D2D通信过程中复用频谱资源对蜂窝用户造成的干扰问题,建立一种优化模型系统,解决用户通信服务质量(quality of service,QoS)和系统能效的权衡问题。针对优化问题中遇到的NP难题,提出一种启发式资源分配算法1-search,降低用户搜索范围以及匹配用户的搜索时间;利用松弛的方法忽略次要干扰的影响,降低算法复杂度。仿真结果表明,1-search算法可以提高系统能效,具有较好的收敛性。To solve the communication energy consumption of the base station’s billions of communication devices and the interference caused by the multiplexed spectrum resources in the D2D communication process on the cellular users,an optimization model system was established to solve the trade-off between the user’s communication quality of service(QoS)and the system energy efficiency.Aiming at the NP hard problem encountered in the optimization problem,a heuristic resource allocation algorithm 1-search was proposed to reduce the user search range and match the user’s search time.The slack method was used to ignore the influence of the secondary interference and reduce the complexity of the algorithm.The simulation results show that the 1-search algorithm can not only improve the system energy efficiency,but also shows better convergence.
