LEO Constellation Design and Link Analysis for Non-Terrestrial Networks

Non-terrestrial networks (NTNs) has played a vital role in providing ubiquitous, secure and resilient infrastructure. It is an indispensable part of 6G’s vision of fully connected intelligent world, as it provides connections for not only terrestrial users but also non-terrestrial platform like flight and unmanned aerial vehicle (UAV). In this paper, we focused on analyzing the performance of Low Earth Orbit (LEO) satellite constellations in 6G non-terrestrial networks, aiming to provide insights into the integration of satellite and terrestrial communications. A LEO Walker satellites constellation is constructed and its coverage has been studied. The spectral efficiency is analyzed for enhanced mobile broadband (eMBB) and massive machine-type communications.
