Outline 3GPP structure and membership 5G vision  5G NR 3GPP releases and 5G NR standards

3GPP structure and membership

3GPP structure Technology Standards for global cellular technologies: GSM, GPRS, EDGE, W-CDMA, HSPA, LTE-(A) (incl LAA), and 5G-NR (including NR-U) Technology Standards for the full system: Radio, Core, Security, O&M, Codecs, Testing

3GPP facts & figures 600+ Companies from 45 Countries 75,000 delegate days per year 100,000 meeting documents per year 1,200 specifications per Release 10,000 change requests (CRs) per year New Release every ~18 months

Membership expansion The 5G effect: variety of new members Agriculture (e.g., John Deere, Husqvana, etc) Car manufacturers (e.g, Volkswagen, Volvo, Toyota) Railway (e.g., International Union of Railways) Industry Automation (e.g., Siemens) Energie sector (e.g., Legrand) Broadcast (e.g., EBU, BBC, TDF) Satellite (e.g., ESO, Inmarsat, THALES) Defense and space (e.g., Lockheed Martin, BAE) Online commerce (e.g., Alibaba) Social Media (e.g., Facebook) Teljes lista: http://www.3gpp.org/about-3gpp/membership

3GPP organization

5G vision  5G NR

5G vision Perfect storm of multiple technology breakthroughs: Low latency radio with fully flexible network Millimeter wave operation Vertical industries going wireless Device revolution for AR/VR Artificial Intelligence and Automation

5G vision  5G NR Ultra wide bandwidth Operation from low to very high bands: 0.4 – 100Ghz Including standalone operation in unlicensed bands (NR-U) Ultra wide bandwidth Up to 100MHz in <6GHz Up to 400MHz in >6GHz Set of different numerologies for optimal operation in different frequency ranges Massive MIMO for better performance

5G vision  5G NR Native forward compatibility mechanisms New channel coding LDPC for data channel, Polar coding for control channel Native support for Low Latency and Ultra Reliability Flexible and modular RAN architecture: split fronthaul, split control- and user-plane Native support for Network Slicing

Release 15 – the advent of 5G

Timeline “Main drop” “Late drop” “Early drop” 2017 2018 2019 2020 Q4 Rel-15 NSA (option-3) freeze Rel-15 NSA (option-3) ASN.1 “Main drop” Rel-15 freeze (incl 5G SA) Rel-15 ASN.1 (incl 5G SA) “Late drop” “Early drop” Rel-15 late drop freeze Rel-15 late drop ASN.1 Rel-16 Study phase Rel-16 Study and Normative phase Rel-16 RAN1 freeze Rel-16 freeze

Why the multiple “drops” “Early drop” for Non-Standalone 5G Addresses the most urgent deployment needs for eMBB Uses LTE anchor with 5G NR in Dual Connectivity configuration Accelerated specification to ensure a single global ecosystem “Main drop” for Standalone 5G Contains full standalone 5G support with 5G Core “Late drop” for some migration needs Contains specs for all potential migration options
