SMTC Configuration and Window Adjustment Strategies for Beam Hopping in NR‐NTN

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Beam hopping is an effective transmission strategy for nonterrestrial networks (NTNs), enabling satellites to allocate limited power and spectrum resources across different geographical regions over time. However, in NR‐based NTN systems, beam hopping complicates synchronization monitoring because synchronization signal block (SSB) arrivals ...
