5G NR Non-Terrestrial Networks: From Early Results to the Road Ahead
For the telecommunications industry, this work provides an overview and simulation-based evaluation of 5G NTN standards, but it is largely a survey and simulation study without novel technical contributions.
This paper reviews the 3GPP 5G NR-NTN standard evolution from Rel. 18 to 20 and evaluates satellite network configurations via ns-3 simulations, demonstrating NTNs' potential to extend connectivity to remote areas and alleviate terrestrial congestion.
This paper overviews the 3GPP 5G NR-NTN standard, detailing the evolution from Rel. 18 to 19 and innovations for Rel. 20. Using realistic ns-3 simulations validated against 3GPP calibration data, we evaluate various satellite network configurations. The results highlight the potential of NTNs to extend wireless connectivity to remote areas, serve requests during emergency, and alleviate terrestrial network congestion.
