5G超密集网络面临的挑战与解决方案研究
|
摘要
超密集组网能够大幅提升无线网络容量,成为解决5G网络数据流量爆炸式增长问题的关键技术之一,但是这种各类无线接入点超密集部署的新型网络形态带来了新的挑战。文章从干扰管理、移动性管理、能效管理、网络架构等四个方面讨论了超密集网络在应用时所面临的挑战,并阐述了相应的解决方案。
Ultra dense network can greatly increase the capacity of wireless network and become one of the key technologies to solve the explosive growth of data traffic on 5 G network. However, the new network form of various types of wireless access points ultra-dense deployment has also brought new challenges. This paper discusses the challenges faced by ultra-dense network in terms of interference management, mobility management, energy efficiency management, and network architecture. At the same time, the corresponding solutions are explained for the challenges.
