Abstract

This article investigates the outage performance of reconfigurable intelligent surfaces (RIS)-assisted hybrid time division multiple access (TDMA) and non-orthogonal multiple access (NOMA)-based indoor flying networks (IFNs), taking into account the influence of dynamic blockages and imperfect successive interference cancellation (SIC) conditions. We utilize a stochastic geometry framework to demonstrate that the RIS-assisted hybrid TDMA–NOMA-enabled IFN system improves outage performance over the traditional OMA scheme with RIS. The results reveal that achieving optimal performance with integration of hybrid TDMA–NOMA into IFNs requires precise adjustments to the range of unmanned aerial vehicle (UAV) deployment heights within a specific threshold.

动态阻塞和不完全SIC条件下TDMA-NOMA-RIS混合动力室内飞行网络性能研究

本文研究了可重构智能表面（RIS）辅助的混合时分多址（TDMA）和基于非正交多址（NOMA）的室内飞行网络（ifn）的中断性能，考虑了动态阻塞和不完全连续干扰消除（SIC）条件的影响。我们利用一个随机几何框架来证明RIS辅助的混合tdma - noma IFN系统比传统的RIS OMA方案提高了停机性能。结果表明，将混合TDMA-NOMA集成到ifn中，需要在特定阈值内精确调整无人机（UAV）部署高度的范围，以实现最佳性能。
