摘要
作为第5代移动通信系统(5G)的一种重要组网方式,基于控制用户分离的高低频无线协作组网在提升区域覆盖能力的同时,还能大幅提升系统整体频谱效率,为接入用户提供无缝高速体验。系统性地介绍了高低频无线协作组网的网络架构及其关键技术,并深入探究无线回程、干扰协调、越区切换等关键技术的研究现状和未来的发展趋势。研究具有超高覆盖率和系统容量的高低频无线协作组网方案对于未来超密集组网的实现有着重要的理论意义。
As an important networking method of 5G,the multi-bands wireless collaborative networking based on the control user separation will improve the capability of regional coverage,and boost the spectrum efficiency of overall system.In this way,it can provide the high speed seamless experience for accessed users.In this paper,the network architecture and some key technologies of multi-bands wireless collaborative networking are introduced systematically,then the research status and future development trend of wireless backhaul,interference coordination,and handover are discussed.The research of multi-bands wireless collaborative networking with ultra coverage rate and system capacity has important theoretical significances for the realization of ultra dense network(UDN).
