基于QoS的5G切片间资源分配

新一代的无线通信实现了万物互联和多样化的业务需求，网络切片可以将网络在逻辑上进行隔离，每个网络服务于一类相似的业务，不同切片之间的业务差异性大，所需资源也不同。为了解决切片间的资源分配问题，为业务提供更好的服务，文章提出了基于服务质量的比例公平资源分配方案，权衡了各个切片之间的公平性和用户需求。将仿真结果与比例公平和最大载干比算法进行了对比，结果表明，新算法能在保证公平性的同时获得较高的用户频谱效率。

Abstract

The new generation of wireless communication has to meet the requirements in the Internet of Things with diversified business. The network slices can logically isolate the network, and each network works in a similar class of business. Therefore, the business differences between different slices is large, and the required resources are also different. In order to solve the problem of resource allocation among slices and provide better service for users, this paper proposes a fair proportion of resource allocation scheme based on Quality of Service （QoS）, which weighs the fairness and user’s requirements in each slice. The simulation results are compared with the proportional fairness and the maximum load-keeping ratio. The results show that the new algorithm can achieve higher user spectrum efficiency while guaranteeing the fairness.
