5G毫米波蜂窝网组网关键技术综述

Review of Networking Key Technology for 5 G Millimeter Wave Network

微小区网络(small cell network)密集化部署是一种解决未来5 G网络组建时面临挑战的重要方法,而无线回传是多基站通过相互协作的方式将海量用户数据传输至核心网的关键技术。结合5 G网络的应用愿景,瞄准5 G中的接入、回传及组网等关键技术,分析了5 G毫米波网络中接入组网、带内回传方面的问题与挑战,并给出了初步的解决方案与仿真结果。此外,又从时隙分配、资源调度等方面简单阐述了毫米波基站的资源分配方式。

Microcell network intensive deployment is an important method to solve the challenges in future formation of 5 G network,and wireless backhaul is a key technology in transmitting massive user data to the core network through mutual coordination of multiple stations. Combined with 5 G network application vision,this paper focuses on the key technology of accessing,backhauling and networking and so on for 5 G,analyzes the main problems and challenges of backhaul architecture,topological structure,stations deployment and accessing method faced by 5 G millimeter wave network,and gives some potential solutions accordingly. In addition,this paper also describes a simple way of resources allocating method of millimeter wave station from the terms of the time slot allocating,resource scheduling and other aspects.
