论文摘要
通过与高海拔平台站和卫星组成的非事物网络（NTN）之间的地面网络之间的合作，将实现下一代通信技术。此外，随着人类踏上在其他行星上建立新栖息地的漫长道路时，NTN和深空网络（DSN）之间的合作将是必要的。在这方面，我们建议使用可重构的智能表面（RIS）来改善这些网络之间的协调，因为RIS与空间操作的大小，重量和功率限制完全匹配。提出了一个全面的RIS辅助非事业和星际通信的框架，以指出挑战，用例和开放问题。此外，根据模拟结果讨论了RIS辅助NTN在太阳闪烁和卫星阻力等环境效应下的性能。
Next-generation communication technology will be made possible by cooperation between terrestrial networks with non-terrestrial networks (NTN) comprised of high-altitude platform stations and satellites. Further, as humanity embarks on the long road to establish new habitats on other planets, cooperation between NTN and deep-space networks (DSN) will be necessary. In this regard, we propose the use of reconfigurable intelligent surfaces (RIS) to improve coordination between these networks given that RIS perfectly match the size, weight, and power restrictions of operating in space. A comprehensive framework of RIS-assisted non-terrestrial and interplanetary communications is presented that pinpoints challenges, use cases, and open issues. Furthermore, the performance of RIS-assisted NTN under environmental effects such as solar scintillation and satellite drag is discussed in light of simulation results.
