The evolution of mobile wireless systems into heterogeneous networks, along with the introduction of fifth generation systems, significantly increased the complexity of radio resource management. Current mobile networks consist of a multitude of spectrum bands, use cases, system features, licensing schemes, radio technologies, and network layers. Additionally, the traffic demand is uneven in terms of spatial and temporal domains, calling for a dynamic approach to radio resource allocation. To cope with these complexities, a generic and adaptive scheme is required for efficient operation of heterogeneous networks. This article proposes using a hierarchical and modular framework as an approach to cover the mentioned challenges and to generalize this scheme to different network layers. The proposed management solution is based on three main components: specialized solutions for individual requirements, exposed to the coordination layer, through abstraction middleware. In this approach, new items can be added as "plugins".

适用于 5G 及更高版本的分层模块化无线电资源管理架构


移动无线系统向异构网络的演进以及第五代系统的引入，显着增加了无线电资源管理的复杂性。当前的移动网络由多种频段、用例、系统功能、许可方案、无线电技术和网络层组成。此外，流量需求在空间和时间域上不均匀，需要动态的无线资源分配方法。为了应对这些复杂性，需要一种通用且自适应的方案来实现异构网络的有效运行。本文建议使用分层和模块化框架作为解决上述挑战并将该方案推广到不同网络层的方法。所提出的管理解决方案基于三个主要组件：针对个体需求的专门解决方案，通过抽象中间件暴露给协调层。在这种方法中，新项目可以作为“插件”添加。
