Other Standards bodies 450 MHz Alliance AISG Bluetooth Broadband Forum (BBF) CableLabs International Special Committee on Radio Interference (CISPR) CTIA  Digital Video Broadcasting (DVB) Project Ecma International Expert Group for Emergency Access (EGEA) Eurescom COST 273 European Radiocommunications Committee (ERC) Fixed Mobile Convergence Alliance (FMCA) Global Certification Forum (GCF) Global TD-LTE Initiative (GTD) GPS Industry Council GSM Association HomeRF Forum IDB Forum IEEE Internet Engineering Task Force (IETF) IrDA International Multimedia Telecomunications Consortium (IMTC) Internet Streaming Media Alliance ISO-ITU expert group ISO MPEG / JPEG ITU-T SG2 JAIN tm (Javatm APIs for Integrated Networks) The Java Community Process (JCP) Liberty Alliance Project LTE/SAE Trial Initiative (LSTI) Metro Ethernet Forum (MEF) NENA NGMN (Next Generation Mobile Networks) oneM2M OMA (Open Mobile Alliance ) Open Networking Foundation (ONF) Open IPTV Forum Object Management Group (OMG) PCS Type Certification Review Board (PTCRB) Portable Computer and Communications Association (PCCA) Presence and Availability Management (PAM) Forum RSA Laboratories SDR Forum Sun Micro Systems Inc Steerco SyncML Initiative Trusted Computing Group (TCG) TeleManagement Forum (TMF) TCCA TIA /TR45 TIA/TR47 TV-anytime Forum Voice eXtensible Mark-up Language (VXML) Forum Wi-Fi Alliance Wireless Broadband Alliance (WBA) WLAN Smart Card Consortium Wireless World Research Forum (WWRF) World Wide Web Consortium (W3C) • Specific inputs, in the form of market requirements may also come in to the Project via any of the 18 Market Representation Partners in 3GPP. These organizations have all signed up to the 3GPP Project scope and objectives. Partners (OP & MRPs) 5G Projects • There is also a lot of external cooperation with other standards bodies and a broad variety of other groups, by way of formal Liaisons. Certification Bodies

  4. The role of 3GPP • 3GPP is part of the invention, proof of concept, standardization, trials, commercialization …cycle • Its role is to specify and maintain a complete system description for mobile telecommunications • The system description is characterized by a number of standardized interfaces, not a description of standardized deployment • This standardization approach enables an interoperable, multi-vendor approach to deployment and generates mass market economies of scale, without stifling innovation

  5. Where are we now on 5G? • 3GPP continues to expand the LTE platform to improve its efficiency to meet the mobile broadband demand • 3GPP is on schedule with the standardization of 5G, addressing the expanded connectivity needs of the future • Phases for the normative 5G work • Phase 1 (Rel-15): Addresses the more urgent subset for commercial deployments • Phase 2 (Rel-16): Completes the IMT 2020 submission, addresses all identified use cases & requirements Release 15 Release 16 Release 17 5G Study 5G Phase 1 5G … 5G Phase 1 5G Phase 2

  6. The IMT vision Initial driver for early adopters of 3GPP 5G Future capabilities will tip the balance of network load towards IoT

  7. Multiple breakthrough technologies Perfect storm of : • Low latency radio with fully flexible network • Artificial Intelligence and Automation • Device revolution for AR/VR • Vertical industries going cellular

  8. Software- and Service-centric Transformation • One Network fits all Open & Flexible Enabler • Telecom OperatorsMultiple Stakeholders • Phones Things • Procedures Services • Static Topology On-demand Resources • Dedicated Hardware Orchestrated Resources • Network FunctionVirtualization • Single NetworkSlice

  9. Project Coordination Group (PCG)

  10. Bringing the work in to the groups

  11. TSG RAN Progress

  12. What is 5G NR ? • Operation from low to very high bands: 0.4 – 100Ghz • Including standalone operation in unlicensed bands • Ultra wide bandwidth • Up to 100MHz in <6GHz • Up to 400MHz in >6GHz • Set of different numerologies for optimal operation in different frequency ranges 3GPP will standardize the Radio Access Architecture and Interfaces for a New Radio Technology for 5G.

  13. What is 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 end-to-end support for Network Slicing TR 38.801 - New RAN architecture

  14. Release 16 – 5G Expansion 2018 Q3 2018 Q4 2019 Q4 2019 Q1 2019 Q2 2019 Q3 5G Vehicle to X (V2X) 5G Industrial IoT 5G Expansion 5G URLLC enhancements 5G for Unlicensed spectrum operation 5G for Satellite 5G above 52.6GHz

  15. V2X evolution • V2X phase 1 - Release 14, basic set of requirements - sufficient for basic road safety service. Vehicles can exchange their own status such as position, speed and heading, with vehicles, infrastructure nodes and/or pedestrians. • V2X phase 2 in Release 15, sidelink updated features include: carrier aggregation, high order modulation, latency reduction, and feasibility study on both transmission diversity and short ‘transmission time interval’ in sidelink. • V2X phase 3 – eV2X – in four use case groups: • Vehicles Platooning • Extended Sensors to increase the perception of the environment for a broad and holistic view of the local situation. • Advanced Driving - semi-automated or full-automated driving. • Remote Driving • Both LTE and NR are candidates to support ‘eV2X’. TSG RAN has agreed (TR 38.913) that eV2X is to complement LTE V2X for advanced V2X services

  16. Industrial IoT and URLLC • Focus on both commercial and industry use • AR/VR, Factory automation, Transport Industry (incl Automotive), Electrical Power Distribution • Establishing Rel-15 baseline performance • Time Sensitive Networking (TSN) • Accurate reference timing, wireless Ethernet, etc… • Reliability and latency enhancements: L1/L2/L3 concepts • Intra-UE prioritization and multiplexing

  17. 5G NR in unlicensed bands RP-181339 • NR-based access to unlicensed spectrum being studied in Release 16 • Looking into scenarios and solutions where NR-LAA is anchored to a legacy LTE carrier by dual-connectivity (DC) • Looking at CA based aggregation with a 5G NR anchor • and considering standalone operation of NR in unlicensed spectrum • Focus is on bands below 7GHz • Co-existence with LTE-LAA and other incumbent technologies “…essential to ensure that a NR-based unlicensed access wideband system operates as a “good neighbour” towards all forms of legacy systems.”

  18. Release 16 – 5G Efficiency 2018 Q3 2018 Q4 2019 Q4 2019 Q1 2019 Q2 2019 Q3 Interference Mitigation 5G SON & Big Data 5G MIMO enhancements 5G Efficiency 5G Location and positioning enhancements 5G Power Consumption improvements Dual Connectivity enhancements Device capabilities exchange Mobility enhancements Non-orthogonal Multiple Access (NOMA)

  19. Positioning in 5G • Going beyond basic regulatory requirements (E911) • Start with identifying accuracy, latency, capacity and coverage requirements • Both commercial and regulatory scenarios • Both indoor and outdoor • Both low (FR1) and high (FR2) frequency bands • TR 38.913 • The NR should enable, and improve if suitable, state-of-art positioning techniques, such as RAN-embedded (Cell-ID, E-Cell ID, OTDOA, UTDOA, etc.) and RAN-external (GNSS, Bluetooth, WLAN, Terrestrial Beacon Systems (TBS), sensors, etc.). Additionally, potential D2D based positioning techniques should be considered. • The NR positioning shall exploit high bandwidth, massive antenna systems, network architecture/ functionalities (e.g. heterogeneous networks, broadcast, MBMS) and deployment of massive number of devices. NR positioning shall support indoors and outdoors use cases. • NR design targets for commercial positioning use cases include: • 1. Support for range of accuracy levels, latency levels and device categories • 2. Support accuracy and latency as defined in TR 22.862 for some (Critical comms) use cases • 3. Reduced network complexity • 3. Reduced device cost • 4. Reduced device power consumption • 5. Efficient signalling over the air interface and in the network • 6. Support for hybrid positioning methods • 7. Scalability (support for large number of devices) • 8. High security • 9. High availability • Support UE speed as defined in TR 22.862 (Critical Comms)

  20. System and Core Network progress

  21. System and Core Network Aspects • System Aspects include: Security, Media and Codecs, Operations and Management, Applications, Terminal and End to End Aspects, Interworking with External Networks and Smart Card Application Aspects • Core Network Aspects include: all functions to support for services provided by the 3GPP system. • These categories are somewhat arbitrary. Some functions could be considered both Core Network and System Aspects.

  22. 5G core network deployments • 5G core network • 5G security architecture • 5G media • 5G charging and management • + Support for eMBB, mCIoT, URLLC & TR38.801

  23. 5G Core Technologies • Orchestration and Virtualization (NFV) – de-couple logical function from hardware • Slicing – logical end-2-end networks tailored to customer needs • Edge Computing (MEC) – resources where they are needed (URLLC) • API Exposure – 3rd party access to 5G services • Service Based Architecture (SBA) – stateless, open, flexible • Harmonized Protocols & Access Agnostic – generic solutions

  24. Control Plane Feature – Service Based Architecture • Compared to previous generations the 3GPP 5G system architecture is service based. That means wherever suitable the architecture elements are defined as network functions that offer their services via interfaces of a common framework to any network functions that are permitted to make use of these provided services. Network repository functions (NRF) allow every network function to discover the services offered by other network functions.  • Each Network Function (NF) as a combination of mono-functional NF services. • NFs provide and consume services to and from each other using a unified protocol. • Stateless NF was specified for access control and mobility management (AMF). • In Release 16 NF service granularity will diminish and more NFs will become stateless.

  25. Future outlook • 5G Vertical support • Vehicle Communication, Mission Critical Communications, Industrial Automation and Verticals, Audio Visual Production, • Enhancements for the system: • 5G LAN, High Precision Positioning, Cellular IoT for 5G, URLLC capabilities, Fixed and Satellite as 3GPP accesses, ONAP interworking, QoS Monitoring, Network Automation, protocol and core network improvements… • 5G will span several releases, look out for early Rel-17 studies*: • Asset Tracking Use Cases • Communication Services for Critical Medical Applications • enhancement for Unmanned Aerial Vehicles (UAVs) • enhanced Relays for Energy efficiency and Extensive Coverage • Network Controlled Interactive Services • Audio-Visual Service Production * Many existing Rel-16 work items and studies will also mature in Rel-17

  26. Conclusions • 3GPP is an industry driven standardization activity with truly global reach • Standardization of interfaces enables an interoperable, multi-vendor approach to deployment and generates mass market economies of scale • NR remains high focus for RAN groups • IMT-2020 ‘5G’ process progressing – 3GPP leading the way • Release 16 focus continues to expand towards new use cases and new sectors • The 3GPP processes are necessarily complex, but we need to adapt to bring new sectors in to the work • 5G will be a multi-Release technology (beyond Release 16)
