IRS assisted hybrid HAP UAV uplink NOMA networks: an interference aware optimization framework
This paper proposes an IRS-assisted hybrid HAP-UAV uplink NOMA framework to enhance sum rates, reliability, and spectral efficiency in dense, interference-limited environments. By jointly optimizing UAV deployment, user association, power allocation, and IRS phase shifts using a Block Coordinate Descent (BCD) framework, the system significantly outperforms conventional aerial and terrestrial benchmarks. Key benefits include improved uplink sum rates (up to 23.03% with IRS), enhanced spectral efficiency, and reduced outage probability, making it a scalable and reliable solution for future 6G networks, particularly for critical applications like mining sector digitalization.

System Model
The system model details a dual-layer IRS-enabled HAP-UAV uplink communication network supporting single-antenna ground users. It integrates UAV 3D deployment, IRS-assisted composite channels, SIC-based uplink NOMA reception, and cross-tier interference management between HAP and UAV layers. This comprehensive model forms the foundation for optimizing network performance in dense, shared-spectrum environments.
Optimization Framework
The proposed optimization framework addresses a highly non-convex mixed-integer problem by formulating a joint uplink sum-rate maximization problem. It rigorously incorporates practical constraints such as UAV mobility limits, user association, power budgets, QoS, and interference thresholds. A Block Coordinate Descent (BCD) approach decomposes this into tractable subproblems for iterative optimization of UAV deployment, user association, power allocation, and IRS phase shifts.
Performance Evaluation
Extensive simulations demonstrate the framework's superior performance compared to conventional benchmarks. It achieves significant improvements in uplink sum rate, average per-user rate, and drastically reduces outage probability across various user loads and SINR ranges. These gains highlight the effectiveness of integrating IRS with hybrid HAP-UAV architecture for robust 6G communication.
