摘　　要：针对5G通信网络系统提供以大容量、高速率、低时延为主要特征的服务导致频谱资源紧缺现象日趋严重的问题,进行了5G频谱资源动态分配的研究,给出了5G异构接入网频谱资源特征描述、表达方法和一种基于双层优化的动态频谱分配方案。仿真实验结果表明,给出的动态频谱分配方案在系统吞吐量和分配公平性两个指标上均有较好表现,具有较好应用价值。To solve 5G communication network systems＇ increasingly serious problem of spectrum resource shortage caused by providing the high-capacity, high-rate and low-latency services, the dynamic allocation of 5G spectrum resources was studied, thus a method for description and expression of the spectrum resources characteristics of 5 G heterogeneous networks was given, and a novel dynamic spectrum allocation scheme based on two-layer optimization was proposed. The results of the simulation experiment showed the proposed dynamic spectrum allocation scheme had better performance in system throughput and fairness of allocation, thus showing its better application value.
