Downlink Co-Frequency Interference Analysis for Beam-Hopping Multi-Layer LEO Constellations Based on Stochastic Geometry

With the rapid deployment of multi-layer low Earth orbit (LEO) constellations, spectrum scarcity has led to severe downlink co-frequency interference. While beam-hopping offers a flexible solution for resource allocation in these systems, its inherent spatio-temporal dynamics introduce significant complexity for interf...

Space-Based Control Node Placement for Joint Handover and Migration Delay Optimization in LEO Networks

A rolling-horizon migration-aware dynamic greedy control node placement algorithm (RH-MA-DGCNP) is proposed, which updates the CN placement and the affiliation between access-layer satellites and CNs at each reconfiguration epoch while jointly considering the handover delay and the migration delay caused by transferrin...
