Non-Terrestrial Networks (NTNs) will constitute a cornerstone of the next-to-come Sixth-Generation (6G) technology. Specifically, Low-Earth Orbit (LEO) satellite constellations play a crucial role, either as a stand-alone networking solution or as a complement to terrestrial networks, in providing network access and services anywhere and anytime with lower latency than … [Read more...] about Tackling Satellite Mobility in Leo-Based Non-Terrestrial Networks: Principles and Enhancements of Feeder Link Switch

IRS-Aided High-Accuracy Positioning for Autonomous Driving Toward 6G: A Tutorial
The increasing number of vehicles on the road places high demands for autonomous driving in future intelligent transportation systems (ITSs). To realize automated services in ITSs, high-accuracy positioning is increasingly important, while positioning simultaneity for high-mobility vehicles should be guaranteed. Existing positioning systems have many constraints in locating … [Read more...] about IRS-Aided High-Accuracy Positioning for Autonomous Driving Toward 6G: A Tutorial
Aerial Base Stations for Global Connectivity: Is It a Feasible and Reliable Solution?
Even though achieving global connectivity represents one of the main goals of 5G and beyond wireless networks, exurban areas are still suffering frequent outages because of the lack of proper telecom infrastructures, which are often available only in urban areas. Indeed, cellular network design is usually capacity driven, and thus the densities of base stations (BSs) follow … [Read more...] about Aerial Base Stations for Global Connectivity: Is It a Feasible and Reliable Solution?
Satellite Clustering for Non-Terrestrial Networks: Concept, Architectures, and Applications
Recently, megaconstellations with a massive number of low Earth orbit (LEO) satellites are being considered as a possible solution for providing global coverage due to relatively low latency and high throughput compared to geosynchronous orbit (GEO) satellites. However, as the number of satellites and operators participating in the LEO constellation increases, inter-satellite … [Read more...] about Satellite Clustering for Non-Terrestrial Networks: Concept, Architectures, and Applications
Multicasting Over 6G Non-Terrestrial Networks: A Softwarization-Based Approach
Multicast/broadcast delivery is a critical challenge of future 6G mobile networks where massive Internet of Things (IoT) deployment and extended reality multimedia such as teleportation are target application scenarios. Non-terrestrial networks (NTNs) are considered essential for the success of 6G, which aims to provide true “global” services by extending mobile access … [Read more...] about Multicasting Over 6G Non-Terrestrial Networks: A Softwarization-Based Approach
