摘要
2019年为5G通信商用元年,随着5G系统的开启,研究人员开始对下一代即第六代移动通信系统(the 6th Generation Mobile Communication System,6G)进行研究。文本探讨了6G通信系统的需求和场景,用4个关键词概括6G愿景:智慧通信、深度认知、全息体验、泛在连接;分析了6G系统面临的技术挑战:超高峰值速率、超海量接入、超高能耗、超广泛在通信网络;论述了6G系统支撑理论(空间信息论、压缩感知、人工智能)和潜在关键技术(太赫兹通信、可见光通信、非正交多址接入技术、超大规模天线技术、频谱认知技术、个性化的极化码技术、新电池与无线能量传输、定位技术)。文本探讨了6G系统的研究现状、需求分析、应用场景、技术挑战、支撑理论和关键技术,构建6G系统的技术框架,为后续开展6G系统研究提供一些指导和建议。
With the deployment of 5G networks in 2019,more and more researchers are beginning to study the next generation,that is,the 6G,mobile communication systems,which are the extensions of 5G systems.The paper first investigates the requirements and scenarios of 6G,and then summarizes the 6G vision with four aspects:smart communication,deep cognition,holographic experience and ubiquitous connectivity.It goes on to analyze the technical challenges of achieving the 6G vision such as ultra-high peak rate,super-mass access,super-high energy consumption,and super-ubiquitous network.Finally,it discusses the 6G-supporting theories(spatial information theory,compressed sensing,artificial intelligence)and potential key technologies(terahertz communication,visible light communication,non-orthogonal multiple access,access technology,ultra-large antenna technology,spectrum awareness technology,personalized polarization code technology,new battery and wireless energy transmission,and positioning technology).This paper attempts to outline the overall framework of 6G by investigating the 6G vision,needs and challenges,as well as the supporting theories and potential key technologies,and aims to provide a directional guidance for the subsequent 6G researches.
