Overview of ITU activities on 5G Martin Adolph, Programme Coordinator, ITU Telecommunication Standardization Bureau

Background: IMT-2000, IMT-Advanced, IMT-2020 All of today’s 3G and 4G mobile broadband systems are based on the ITU’s IMT standards. ITU established the detailed specifications for IMT-2000 and the first “3G” deployments commenced around the year 2000. In January 2012, ITU defined the next big leap forward in wireless cellular technology – IMT-Advanced – and this is now being progressively deployed worldwide. The detailed investigation of the key elements of IMT-2020 is already well underway, once again using the highly successful partnership ITU-R has with the mobile broadband industry and the wide range of stakeholders in the 5G community.

Organizations involved in the development of IMT 3GPP, 3GPP2 5G Americas 5G Infrastructure Public Private Partnership 5G Innovation Centre APT Wireless Group Fifth Generation Mobile Communications Promotion Forum ARIB ATIS CCSA CDG ETSI EU METIS Project GSMA IEEE IMT‐2020 Promotion Group ITRI NGMN NYU Wireless TSDSI TIA TTA TTC UMTS Forum WiMax Forum Wireless World Research Forum We welcome any other interested partners

ITU-R WP 5D is working together with these partners in the same open process to establish the criteria for IMT-2020. Recommendation ITU‑R M.2083‑0, approved in September 2015, defines the framework and overall objectives of the future development of IMT for 2020 and beyond.

ITU 5G Vision (i) Recommendation ITU‑R M.2083‑0, approved in September 2015, defines the framework and overall objectives of the future development of IMT for 2020 and beyond. Source: Recommendation ITU-R M.2083, https://www.itu.int/rec/R-REC-M.2083-0-201509-I/en (09/2015)

ITU 5G Vision (ii) IMT-2020 would be able to provide 1 ms over-the-air latency, capable of supporting services with very low latency requirements. “To achieve ultra-low latency, the data and control planes may both require significant enhancements and new technical solutions addressing both the radio interface and network architecture aspects.” Source: Recommendation ITU-R M.2083, https://www.itu.int/rec/R-REC-M.2083-0-201509-I/en (09/2015)

New radio interfaces The broad range of IMT-2020 requirements and use cases envisaged may necessitate specification of new radio interfaces as well as operation in new frequency bands Extremely high data rates Very low latency Long range, low power applications Interworking with IMT-Advanced will need to be ensured Need to limit the complexity of terminal equipment (handsets, but more generally, things)

ITU-T Focus Group IMT-2020 Studying the requirements and standardization needs of the wireline in support of 5G (explicitly non-radio/RF based) Chair: Huawei; Vice-Chairs: CMCC (China), NTT (Japan), TI (Italy), ETRI (Korea) Using ITU-R M.2083 and other 5G whitepapers as starting point, extrapolate what a 5G wireline network would look like Led production of report with 85 identified gaps, http://itu.int/en/ITU-T/focusgroups/imt-2020

2015: Identifying the non-radio gaps Executive Summary + Gaps + Supplemental info Useful background A.17 OAM protocols Priority: High Description: OAM protocols are not standardized in some parts of IMT networks such as the front haul network. Standard OAM protocols should be studied for fault management and performance management between network equipment that may be commonly used across the IMT-2020 network. Related work: A.18 End-to-end network management in a multi-domain environment Priority: High Description: Multiple network management protocols in different network domains make it difficult to support unified network operations over multiple network domains. A unified end-to-end network management should be considered to ensure compatibility and flexibility for the operation and management of an IMT-2020 network. Related work: SG13 85 gaps: E2E QoS; Network softwarization; Fronthaul/Backhaul; Network architecture; Emerging networking technologies – information centric networking Network slicing. A.19 Mobility management for distributed flat network Priority: High Description: As the IMT-2020 core network is envisioned to be a flat distributed network, which is composed of the multiple distributed gateways to cope with traffic explosion and latency requirements of applications, mobility management should be studied aligning with those architectural changes. Related work: 3GPP, SG13 Network Architecture E2E QoS Network Softwarization Information centric networking Fronthaul/ Backhaul

2016: Standards and PoCs Tackling the gaps through: Draft international standards: Network softwarization, incl. slicing for front haul/back haul; Information centric networking; Network architecture refinement and fixed mobile convergence; New traffic models and associated QoS and OAM aspects applicable to 5G architecture. Demonstrations and prototyping: Candidate: E2E network slicing Output A: Several draft Recommendations close to final, to be progressed by ITU in 2017 Output B: Proofs of concept, e.g., E2E network slicing leveraging open source projects

Moving forward 8-11 March 2016, Seoul, Korea (hosted by KT): Initiated work on draft standards, saw demos and discussion of PoCs. 17-20 May 2016, Beijing, China (hosted by China Mobile, Datang): Progress reports/draft standards; narrow down, agree on scope of PoCs and demos. TBC: 6-9 September 2016, Palo Alto, United States (hosted by PARC): Progress reports/draft standards; progress the development of PoCs and demos. TBC: 8-11 November 2016, Geneva, Switzerland (ITU HQ): Finalize and adopt reports/draft standards; presentation of PoCs and demos. 25 May 2016, San Diego, United States: ITU/NGMN Workshop on Open Source and Standards in 5G.
