超密集组网通过小基站加密部署提升空间复用的方式,成为解决未来5G网络数据流量1 000倍以及用户体验速率10~100倍提升的有效解决方案。然而,小区密集部署带来的干扰问题以及小基站较小的覆盖范围导致的高速移动用户频繁切换问题,会降低网络容量和用户体验。因此,为了同时考虑未来5G超密集组网“覆盖”和“容量”的问题,提出了以控制承载分离以及簇化集中控制为主要技术特征的5G超密集组网网络架构。除此之外,针对宏—微和微—微的超密集组网部署场景,给出了具体实现方案。更进一步地,针对5G超密集组网网络架构中可能存在的问题与挑战进行了讨论,为后续研究发展提供参考。
Ultra dense network(UDN)is referred to as the most efficient technique for meeting the challenges of 1 000 times higher trafficvolume and 10~100 times higher user data rate,which can improve the network capacity dramatically through network densification.However,due to the limited coverage and higher density of small cell,the problems of frequent handover and inter-cell interference become intractable,which degrade the system capacity and user experience.Therefore,in order to satisfy the challenges of coverage and capacity simultaneously,the architecture of 5G ultra dense network was proposed,which was characterized as the separation of control and user planes and cluster-based centralized control.Besides,regarding to the UDN scenarios of macro-micro and micro-micro,different solutions were presented,respectively.In addition,the problems and challenges of the architecture of 5G ultra dense network were also discussed in detail,providing reference for future research and development.
