Cross-link Interference Modeling in 6G Millimeter Wave and Terahertz LEO Satellite Communications
One of the important questions when discussing next-generation near-Earth
mmWave and terahertz (THz) band satellite communications as an integral part of
the 5G-Advanced and 6G landscape is the potential interference-related issues
when deploying such systems. While the space-to-ground and ground-to-space
interference has been explored in multiple works already, the interference at
mmWave and THz cross-links, the links between the satellites themselves, have
not been extensively studied yet. However, severe cross-link interference may
both challenge the reliability of the data exchange within the constellation,
as well as compromise the efficient co-existence of multiple satellite
constellations (i.e., by different providers) covering the same or neighboring
areas. In this paper, both relevant mathematical models and extensive
simulation studies are presented for cross-link mmWave and THz satellite
communications. Our results indicate that the cross-link interference in the
considered setups is a non-negligible factor that must be further explored and
accounted for in the design and deployment of next-general mmWave and THz
satellite communication systems.Comment: 7 pages, 7 figures, accepted to IEEE International Conference on
