Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems
International Journal of Satellite Communications and Networking, Volume 44, Issue 6, Page 757-765, November/December 2026.ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...
