Two non-geostationary orbit (NGSO) mega-constellations over shared spectrum leads to inter-constellation interference. Existing mitigation mainly relies on frequency/time partitioning, spatial isolation and satellite selection. However, these approaches may sacrifice resource reuse or be constrained by spatial geometry...

Time-varying aggregate interference from low-Earth-orbit (LEO) satellites challenges terrestrial-network (TN) protection, whereas conservative control degrades LEO quality of service (QoS). This letter proposes a hierarchical framework combining geometry-based interference estimation, QoS-constrained power control, ada...
The dynamic topology and heterogeneous traffic demands of multi-satellite systems present substantial challenges for beam-hopping (BH) resource management. This letter develops a topology-aware cooperative BH framework for multi-satellite systems under partial observability. A lightweight load-balancing scheme first de...
