B5G:泛在融合信息网络

B5G: Ubiquitous Fusion Information Networks

延续"线"—"面"—"体"的演进趋势,超5代移动通信系统(B5G)继续提高通信速率,拓展通信空间,完善通信智慧,演进为泛在融合信息网络。B5G使用更高的频段作为信号载体,数据速率达到太比特每秒量级。伴随网络性能的增强,B5G的适用空间拓展至陆海空天。与以往移动通信系统不同,人工智能(AI)成为B5G性能提升的强劲引擎。基于AI的干扰管理、深度学习智能信号处理以及太赫兹技术成为物理层关键技术。基于极化码的中继、多天线、多址技术是传输层关键技术。基于AI的移动网络架构、面向人机物泛在融合的全析网络架构以及认知增强与决策推演的智能定义网络架构等方式的新架构被应用于网络层。

Following the'line-plane-cube'evolution trend, Beyond Fifth Generation(B5 G) in mobile communication system aims at improving communication data rate, extending communication dimensions, implementing communication intelligence and is on the way to evolve into ubiquitous fusion information networks. Higher spectrum bands are used in B5 G and the peak data rate could be T bits per second. With the enhancement of network ability, the support scenarios of B5 G includes the land, the sea, the sky and the aerospace. Different with the existing generations, artificial intelligence(AI) becomes a powerful engine for B5 G. The key technologies in the physical layer include the AI-based interference management, deep learning intelligent signal processing and THz technology.The transport layer uses the polar code-based relay, multiple input multiple output(MIMO) and multiple access technologies. The AIbased mobile network framework, the ubiquitous fusion fully-analyzed network framework for human-machine-things and the intelligent definition network framework for cognitive enhancement and decision deduction are used in the network layer.
