Spectrum allocation in non-terrestrial wireless networks is efficiently and intelligently managed by predicting traffic loads for beam cells using historical network traffic data and a trained model. Beam cells with higher predicted traffic loads are assigned larger spectrum bandwidths, while other beam cells are assigned smaller, non-overlapping bandwidths that dynamically change frequencies according to a predefined hopping sequence. Example solutions disclosed herein optimize bandwidth utilization and minimize interference, enhancing service quality and coverage in satellite communication systems.
