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

open access: yesInternational 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 ...

Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Long‐Term Propagation Measurements in Madrid in a Q‐Band Satellite‐to‐Earth Link

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The Q/V band (40/50 GHz) is gaining interest as satellite operators will need larger bandwidth to be able to provide their services, which are experiencing an increasingly high demand. An accurate characterization of the satellite‐to‐Earth propagation channel is of paramount importance to guarantee a high level of quality of service, by ...

Spaceborne Distributed Array Processing for Precision Source Localization

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Satellite‐based signals intelligence and spectrum sensing increasingly rely on low‐latency signal localization. However, operational processing chains often remain ground‐based, stressing feeder links and limiting scalability as constellations grow.
