  1. 5G NTN Prof. Kiran Kuchi IIT HyderAbad

  2. NTN: Non Terrestrial Networks • 3GPP enables the cooperation of satellite with terrestrial networks to provide the 5G services with the promised key performance indicators: • Global coverage & mobility • Service ubiquity • Overall network reliability and security NG-C NG-U Data Network N6 NGC UE gNB

  3. 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

  4. Satellite Subsystem in 5G • NTN: • Space-borne vehiclesin • Low Earth Orbits (LEO) • Medium Earth Orbits (MEO) • Geostationary Earth Orbit (GEO) or in Highly Elliptical Orbits (HEO) • Airborne vehiclesHigh 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
