摘要
随着5G走向商用,6G日益成为业界研究的热点。空天地一体化具有扩展覆盖、节省成本等多种优势,被业界当作6G的重要关键技术。对6G的空天地一体化系统设计和关键技术进行研究,首先分析了空天地一体化系统设计的驱动力,探讨了空天地一体化系统设计的基本理念,剖析了空天地一体化系统设计面临的问题和挑战,最后提出了空天地一体化系统设计的系列关键技术并进行了深入研究,为后续6G的关键技术研究、系统设计与标准推进,以及6G的产业化提供参考和借鉴。
As 5G goes into commercial use,6G has increasingly become a research hotspot by academics and industries.The integrated air-space-terrestrial communication(IASTC)is regarded as an important key technology of 6G,due to its advantages such as expanding coverage and saving cost.In this paper,the system design and key technologies of 6G IASTC are studied.Firstly,the driving force of 6G IASTC is analyzed,then the basic concept of system design is discussed,and then the difficulties and challenges are analyzed.Finally,a series of key technologies for 6G IASTC are proposed and discussed in depth.The research of this paper will provide reference for future work on 6G,including key technology research,system design,standard promotion and also industrialization.
