5G NTN PROF. KIRAN KUCHI IIT HYDERABAD
NTN: Non Terrestrial Networks 3GPP enables the cooperation of satellite with terrestrial networks to provide the 5G services with the promised key performance indicators: oGlobal coverage & mobility oService ubiquity oOverall network reliability and security NG-C NG- U N6 Data Network UE gNB NGC
NTN: Use cases 5G service roll out in un-served or underserved areas to upgrade the performance of terrestrial networks. Reinforce service reliability by providing service continuity for user equipment or for moving platforms. Increase service availability everywhere; especially for critical communications, future railway/maritime/aeronautical communications Enable 5G network scalability through the provision of efficient multicast/broadcast resources for data delivery towards the network edges or even directly to the user equipment
Satellite Subsystem in 5G NTN: Space-borne vehicles in Low Earth Orbits (LEO) Medium Earth Orbits (MEO) Geostationary Earth Orbit (GEO) or in Highly Elliptical Orbits (HEO) Airborne vehicles High Altitude Platforms (HAPs) encompassing Unmanned Aircraft Systems (UAS) (tethered UAS, Lighter than Air UAS and Heavier than Air UAS) - operating at altitude; typically between 8 and 50 km, quasi-stationary Roles and benefits of satellites in 5G have been studied in 3GPP Release 14 Service provisions considering integration of 5G in satellite access
