Overview

This investigation shows enhanced downlink performance in UAV-assisted satellite networks, indicating significant efficiency improvements.

Key Points

  • The aim is to maximize the downlink sum-rate in a UAV-assisted satellite network using hybrid NOMA and OMA transmission.
  • Developed an end-to-end optimization framework for UAV placement.
  • Utilized a greedy transmission mode selection for performance evaluation.
  • Implemented a KKT-based scheme for bandwidth allocation in the satellite-to-UAV backhaul.
  • Achieved a 25–35% improvement in system sum rate and spectral efficiency under low satellite elevation angles.
  • Increased average user rate by up to 37% with moderate network sizes.
  • Maintained consistent performance gains as user numbers increased.
