摘　　要：三维连接技术作为地面网络(TN)与非地面网络(NTN)的融合组网技术,既能解决TN空天地海覆盖受限与NTN服务场景受限问题,又能促进后5G(B5G)与6G网络基础设施产业链的健康发展。首先简述了三维连接技术的发展历程,然后重点介绍了未来两年将要完成的5G NTN标准需求、部署结构、空中接口、频谱与终端方面的设计考虑,最后给出了对未来B5G/6G三维连接技术展望,提出了需要全球产学研机构共同研究创新的关键技术问题。Three-dimensional (3D) connectivity technology, as the integrated networking technology of terrestrial network(TN) and non-terrestrial network (NTN), can not only solve the TN’s limited coverage of space, sky and sea, and theNTN’s limitation of service scenarios, but also promote the healthy development of the industry chain of beyond 5G(B5G) and 6G network infrastructure. This paper briefl y introduces the development process of the 3D connectivitytechnology, and investigates the service requirements, the deployment architectures, the air interface design, and thespectrum and terminal aspects of 5G NTN standards to be completed in the future two years. Finally, we anticipatethe potentials of the 3D connectivity of future B5G/6G, and its key technologies to be further studied by the globalindustry and academia.
