作为5G关键技术之一的超密集组网是满足未来千倍数据流量需求的主要手段。然而,网络密集化部署将导致严重的干扰问题,因此干扰管理是5G超密集网络中的重要研究课题。首先从规避及利用两个方面归纳总结现有的干扰管理算法。其次,为了更好地适应未来5G无线网络智能化、异构化的发展趋势,提出了一种智能的无线网络干扰管理体系,实现了无线网络环境与干扰管理的动态紧耦合。最后,从干扰管理与资源管理的本质联系这一角度出发,介绍了3种联合异构网络资源的新型干扰管理算法,有效实现了网络资源的高效利用和网络容量的提升。
As one of the key technologies in 5G networks, ultra-dense wireless network is utilized to approach thefuture 1 000 ultra-high traffic volume. Nevertheless, the dense deployment of network nodes would result in severeinterference, and thus interference management was proposed as the big principle behind 5G ultra-dense wirelessnetworks research. Firstly, the interference management schemes were classifed from two aspects: avoidance andutilization. Then, an intelligent interference management architecture was proposed to accommodate the developmenttrend of future wireless networks in terms of intelligence and heterogeneity in order to realize the dynamic tightlycoupled interference management of wireless network environment and interference management. Taking the intrinsicrelationship between interference management and resource management into consideration, three cutting-edgeinterference management schemes were introduced, which could significantly improve the network resource utilizationand the network capacity.
