作为2030年智能信息社会的关键推动因素，6 G网络有望提供上级于5G的性能，并满足新兴服务和应用。在本文中，我们提出了我们对6 G的愿景，并描述了每秒数TB（Tb/s）和智能6 G网络的使用场景和要求。我们提出了一个大的维度和自治的网络架构，集成空间，空中，地面和水下网络，提供无处不在的和无限的无线连接。我们还讨论了用于自主网络和创新空中接口设计的人工智能（AI）和机器学习[1]，[2]。最后，我们确定了6 G生态系统的几项有前途的技术，包括太赫兹（THz）通信、超大规模天线阵列[即，超大质量（SM）多输入多输出（MIMO）]、大型智能表面（利斯）和全息波束成形（HBF）、轨道角动量（OAM）复用、激光和可见光通信（VLC）、基于区块链的频谱共享、量子通信和计算、分子通信以及纳米物联网。
A key enabler for the intelligent information society of 2030, 6G networks are expected to provide performance superior to 5G and satisfy emerging services and applications. In this article, we present our vision of what 6G will be and describe usage scenarios and requirements for multi-terabyte per second (Tb/s) and intelligent 6G networks. We present a large-dimensional and autonomous network architecture that integrates space, air, ground, and underwater networks to provide ubiquitous and unlimited wireless connectivity. We also discuss artificial intelligence (AI) and machine learning [1], [2] for autonomous networks and innovative air-interface design. Finally, we identify several promising technologies for the 6G ecosystem, including terahertz (THz) communications, very-large-scale antenna arrays [i.e., supermassive (SM) multiple-input, multiple-output (MIMO)], large intelligent surfaces (LISs) and holographic beamforming (HBF), orbital angular momentum (OAM) multiplexing, laser and visible-light communications (VLC), blockchain-based spectrum sharing, quantum communications and computing, molecular communications, and the Internet of Nano-Things.
