Ensuring The Performance of NTN-NR 5G Communications

Abstract

The performance of 5G Non-Terrestrial Networks (NTN) combined with Low Earth Orbit (LEO) satellite constellations is evaluated in this thesis. The key performance indicators (KPIs), throughput, latency, coverage, and power efficiency are estimated across several scenarios where different subcarrier spacing (SCS), modulation schemes, and altitude are tested. The research emphasizes NTN’s contribution in balancing coverage, capacity, adaptive SCS selection, altitude deployment and hybrid designs. Difficulties in HARQ adaptation, interference control, and Doppler shift point out areas of future study direction.
