5G NR Non-Terrestrial Networks: Open Challenges for Full-Stack Protocol Design
Francesco Rossato, Mattia Figaro, Alessandro Traspadini +7
As 5th generation (5G) networks continue to evolve, there is a growing interest toward the integration of Terrestrial Networks (TNs) and Non-Terrestrial Networks (NTNs). Specifical…
5G NR Non-Terrestrial Networks: From Early Results to the Road Ahead
Mattia Figaro, Francesco Rossato, Marco Giordani +7
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 ca…
Discrete Beamforming Optimization for RISs with a Limited Phase Range and Amplitude Attenuation
Dogan Kutay Pekcan, Hongyi Liao, Ender Ayanoglu
This paper addresses the problem of maximizing the received power at a user equipment via reconfigurable intelligent surface (RIS) characterized by phase-dependent amplitude (PDA)…
Achieving Optimum Received Power with Elementwise Updates in the Least Number of Steps for Discrete-Phase RISs
Dogan Kutay Pekcan, Ender Ayanoglu
The problem of optimizing discrete phases in a reconfigurable intelligent surface (RIS) to maximize the received power at a user equipment is addressed. Necessary and sufficient co…
