5G绿色超密集无线异构网络:理念、技术及挑战
发布时间：2019-01-03 06:20
【摘要】：超密集无线异构网络被公认为是大幅提升无线网络容量、解决蜂窝网所面临的1 000倍数据量挑战最富有前景的一种5G组网技术。但是,与5G愿景背道而驰的是网络的超密集化部署在提升谱效的同时也极度地增大了系统的能耗,降低了通信能效。旨在利用超密集异构网络具有的全网管理能力和网络分集效应,从宏观的网络匹配与微观的资源聚合两方面探索超密集异构网络绿色演进的关键理论与技术。首先论述了绿色演进的基本理念,然后提出了利用负载自适应的基站开关控制、主动缓存和干扰感知的跨网资源分配三大关键技术来提升网络的能效,同时也讨论了每种技术在应用时所面临的挑战。
[Abstract]:Ultra-dense wireless heterogeneous networks are widely recognized as a 5G networking technology that can greatly enhance the capacity of wireless networks and solve the challenge of 1,000 times the amount of data faced by cellular networks. However, contrary to the 5G vision, the super-dense deployment of the network not only improves the spectral efficiency, but also increases the energy consumption of the system and reduces the communication energy efficiency. The aim of this paper is to explore the key theories and technologies of the green evolution of ultra-dense heterogeneous networks from two aspects: macroscopic network matching and micro resource aggregation, taking advantage of the network management capability and network diversity effect of ultra-dense heterogeneous networks. This paper first discusses the basic concept of green evolution, and then proposes three key technologies to improve network energy efficiency, which are load adaptive base station switch control, active buffer and interference sensing resource allocation. At the same time, the challenges faced by each technology in its application are also discussed.
