摘要
近年来,5G的建设取得了丰硕的成果.以3GPP为首的标准组织正在积极开展5G第二阶段(5G Advanced,5G-A)以及6G的候选技术及标准工作.电磁波的轨道角动量技术(Orbital Angular Momentum,OAM)是IMT-2030推进组在6G布局的重要研究方向,以其优异的理论容量性能在学术界和产业界获得了大量关注.文章总结OAM技术应用于通信的优势,例如可支持视距超多流并行传输,提升通信物理层安全,与智能超表面(Reconfigurable Intelligence Surface,RIS)技术结合赋能等,提出在大数据和工业互联网等应用场景下,利用OAM技术建立的超大规模无线数据中心将助力实现数据要素深度参与工业生产,提升全产业链生产效率,推动6G与产业协同发展.
Abstract
The construction of the Fifth-Generation Mobile Communication System(5G)has achieved fruitful results recently.Standard organizations like 3GPP are actively carrying out the work on candidate technologies and standards for the 5G Advanced(5G-A)phase and the Sixth-Generation Mobile Communication System(6G).The Orbital Angular Momentum(OAM)of electromagnetic waves is an important research direction in the 6G layout of the IMT-2030 promotion group,it has attracted a lot of attention in the academic and industrial circles due to its excellent theoretical capacity performance.OAM can support ultra-multi-stream parallel transmission over line-of-sight,enhance the physical layer security of communications,and can be combined with Reconfigurable Intelligent Surface(RIS)technology.Scenarios such as big data and the industrial internet,the establishment of ultra-large scale wireless data centers using OAM technology will help to realize the coordinated development of 6G with industry.
