The contemporary mobile communication has undergone a significant shift toward a novel phase characterized by the emergence of beyond 5G (B5G) and 6G technologies. These advancements underscore a focus on enhanced spectral efficiency, minimized latency, and expansive connectivity. This paper thoroughly examines 6G wireless communication networks, including their architectural framework, key technologies, application scenarios, use cases, and challenges. The architectural blueprint of 6G networks integrates space, terrestrial, aerial, and undersea communications to facilitate deep connectivity across various scenarios, which is to meet the increasing future communication requisites. Toward this end, the paper proposes 15 key technologies such as terahertz communication, visible light communication, dynamic spectrum sharing, ultra-massive multiple-input multiple-output (MIMO), and in-band full-duplex. Furthermore, typical scenarios and emerging use cases of 6G are detailed. Conclusively, this paper expounds upon potential challenges in developing and suggests the corresponding solutions, fostering a global dialogue on this transformative technological frontier.
当代移动通信已朝着一个以超越5G（B5G）和6G技术的出现为特征的新阶段发生了重大转变。这些进步突出了对提高频谱效率、最小化延迟和扩大连接性的关注。本文全面研究了6G无线通信网络，包括其架构框架、关键技术、应用场景、用例和挑战。6G网络的架构蓝图整合了空间、地面、空中和海底通信，以促进各种场景下的深度连接，从而满足未来不断增长的通信需求。为此，本文提出了太赫兹通信、可见光通信、动态频谱共享、超大规模多输入多输出（MIMO）和带内全双工等15项关键技术。此外，还详细介绍了6G的典型场景和新兴用例。最后，本文阐述了发展中可能面临的挑战并提出了相应的解决方案，促进了在这一变革性技术前沿的全球对话。
