3GPP Workshop: IMT 2020 Submission to ITU-R WP5D and Timelines for 5G Standards Completion

3GPP RAN for IMT 2020, by Balazs Bertenyi, Chairman of 3GPP RAN (Nokia):

The Workshop on 3GPP submission towards IMT-2020 was held in Brussels, Belgium, October 24-25, 2018, hosted by the European Commission. The meeting was intended to inform the Independent Evaluation Groups and the industry in general about the 5G mobile communication system and corresponding evaluations that 3GPP has and will submit as a candidate for IMT-2020 to ITU-R. The workshop also had a live streaming service kindly provided by the host and announced shortly before the meeting via the 3GPP web page (see reference below) and the RAN reflector.

Introduction:

3GPP has been working extremely hard to bring 5G NR standards to the industry in an accelerated manner. Non-standalone 5G NR (New Radio) was completed in December 2017, and the corresponding ASN.1 has been stabilized in June/2018.

Standalone 5G NR was completed in June 2018, and the corresponding ASN.1 scheduled to be frozen in September/2018.

Some of the architecture options to facilitate migration from LTE to 5G NR will be completed in December 2018 and will still be within 3GPP Release 15.

3GPP has also approved the work program for Release 16 containing a host of new and enhanced functionalities for 5G NR. The target completion for Release 16 is December/2019.

3GPP submission to IMT2020 (ITU-R WP5D) will contain both Release 15 and (mostly) Release 16 functionality.

Busting a Myth: 3GPP Roadmap to true 5G (IMT 2020) vs AT&T “standards-based 5G” in Austin, TX

10 thoughts on “3GPP Workshop: IMT 2020 Submission to ITU-R WP5D and Timelines for 5G Standards Completion

  1. As per the IMT-2020 process for “Submission/Reception of the RIT and SRIT proposals and acknowledgement of receipt” and in accordance with Document IMT-2020/2(Rev.1), the evaluation process for Independent Evaluation Groups (IEGs) started from Working Party (WP) 5D 31st meeting in October 2018 and will proceed until ITU-R WP 5D 34th meeting in February 2020.

    Considering the tight schedule of the evaluation process, and the potential intensive evaluation work which addresses a variety of configurations as well as Test Environments for the three Usage Scenarios (eMBB, mMTC and URLLC) as defined in Report ITU-R M.2412, WP 5D expects to receive the final evaluation report(s) at the 34th WP 5D meeting and recommends that the independent evaluation groups to provide interim evaluation reports before or at the 33rd WP 5D meeting, which is tentatively scheduled in December 2019.

  2. From an AT&T-Ericsson Jan 15 2019 Contribution to ITU-R WP 5D on IMT 2020:

    Operators, manufacturers, and technology developers along with other ITU-R Members have expressed significant concerns about impacts to global roaming, customer confusion/misperception, and other matters if “look alike yet variant standards” are created, where the variant standard purports to be closely aligned with one particular global set of specifications/standards and yet does not clearly and explicitly identify itself as a separate and unique “technology and standard” in its presentation, naming, marketing and/or adoption.

    Document only available to ITU TIES members

  3. Guidance offered by Mr. Francois Rancy, as a Director of the ITU Radiocommunication Bureau (ITU-R) in his opening remarks to the 19 November, 2018 ITU-R Study Group 5 meeting where he expressed the following views on IMT-2020:

    “Beyond WRC-19, I would like to stress the importance of the work of the Study Group for IMT-2020 telecommunications. Of course the work of the world conference is essential to provide harmonized spectrum, but in addition to that, the work of the standards in my mind is essential to ensure all those economies of scale for hopefully one standard and interoperability and roaming throughout the world.

    And if we want to build the global village which is the ambition of the ITU, we need to try to converge on a single standard harmonized worldwide to ensure. Not all parts of the world can be connected especially in the 50% population which currently is yet to be connected and to be able to do that we need to rely on the world’s globally harmonized standard. So thanks for your efforts.

    We have to keep in mind that investments for 5G will probably represent something like 10,000 billion dollars worldwide and when you are in this type of amount of money you can’t afford to have two standards, you can’t afford to divide the world into two incompatible types of devices. So this is really the challenge that Study Group 5 and Working Party 5D have to meet and I’m sure you are aware of the importance of these discussions…”

  4. From ITU NEWSLETTER:

    The first full-scale commercial deployments for 5G are expected shortly after IMT-2020 specifications are finalized in 2020. Regulators around the world are already auctioning licenses to operate 5G networks in the frequency bands allocated by ITU and identified or expected to be identified for IMT.

    ITU’s role, through its Radiocommunication Sector (ITU-R), is to ensure the rational, equitable, efficient and economic use of the radio-frequency spectrum by all radiocommunication services, including satellite services, in particular by avoiding and eliminating harmful interference.

    For this purpose, the radio-frequency spectrum is divided into frequency bands which are allocated to radiocommunication services in such a way that each band may be used only by services which can co-exist with each other. These allocations and the procedures ensuring the international recognition and protection from interference of spectrum uses in each country and in Space are contained in the ITU Radio Regulations (RR). The RR is an international treaty ratified and applied by all ITU Member States. It has been in force since 1906 and is updated every four years by the ITU World Radiocommunication Conferences (WRCs) to take into account the evolution of technologies and spectrum uses.

    As part of the four-year process of studies and preparations for the ITU World Radiocommunication Conference 2019 (WRC-19), global stakeholders are working towards building consensus to allocate and identify additional spectrum for International Mobile Telecommunications (IMT, the generic term used by ITU to designate 2G, 3G, 4G, 5G and future generations of mobile broadband services) during that conference.
    ………………………………………………………………………………………………..
    Setting standards for globally harmonized, stable, secure and reliable 5G

    ITU has a rich history in the development of global standards for mobile communications. The framework of standards for international mobile telecommunications (IMT) spans 3G and 4G industry perspectives and will continue to evolve as 5G with IMT-2020.

    In early 2012, ITU initiated the development of “IMT for 2020 and beyond”, setting the stage for 5G research activities and establishing the requirements and vision for 5G. Under ITU’s IMT-2020 programme, ITU membership is developing the international standards to achieve well-performing 5G networks.

    ITU standards are supporting networking innovations such as software-defined networking, network virtualization, information-centric networking and advanced fronthaul and backhaul. These innovations will play a key role in making 5G networks faster, smarter and more cost-effective. These ITU standards are also enabling telecommunication companies to provide innovative services as they adapt to shifting customer needs in an era of great change. These standards for software-driven networking innovation are expected to achieve their full potential in the 5G environment.

    This standard-setting process unites governments, regulators, mobile operators, manufacturers, industry organizations, academia and other standardization bodies from around the world, to support the development of 5G applications in the areas of network reliability and stability, cybersecurity, data privacy, the analysis of Big Data, energy efficiency and Artificial Intelligence to enhance the efficiency of 5G networks. ITU’s adoption of the IMT-2020 standards will provide investors in 5G networks with the assurance that these standards will be applied universally, bringing economies of scale, and thus demonstrating the benefits of global harmonization.

    [1] Network stability allows everyone to communicate, access data, and share information reliably, as needed.
    [2] Network security is an over-arching term that describes that the approach, policies and procedures implemented by a network administrator to avoid unauthorized access, exploitation, or modification of a network and its resources.
    [3] Reliability is when computer-related networks or components perform consistently according to expectations.

  5. 3GPP Release 16, when completed (early 2020?), will have the ultra low latency included. It is NOT available in any so called “5G” networks till then! So don’t expect ultra low latency on any “5G” smartphone for several years. Note also that 1 way latency is the cumulative delay through: the access network, mobile packet core, and edge network at the service provider point of presence. It is NOT just the access network (e.g. 5G NR transmission).

    Title: Study on physical layer enhancements for NR ultra-reliable and low latency case (URLLC)
    Status: Draft
    Type: Technical specification (TS)
    Initial planned Release: Release 16

    The follow key use cases were identified to be considered:
    – Release 15 enabled use case improvements
    – Such as AR/VR (Entertainment industry)
    – New Release 16 use cases with higher requirements
    – Factory automation
    – Transport Industry, including the remote driving use case
    – Electrical Power Distribution

  7. From the ITU-R 5D Chairman’s report (18 March 2019) of their 11-15 February 2019, Geneva, Switzerland meeting:

    IMT-2020/VVV
    This meeting reviewed the received a number of input contributions on “Process and use of the Global Core Specification (GCS), references, and related certifications in conjunction with Recommendation ITU-R M.[IMT 2020.SPECS]” and there continues to be two diverse philosophies on how to proceed with the document – one desiring to significantly alter the process to support specific national needs in the transposition phase of the process and the other demonstrating how the same objective could be accomplished with the existing process remaining unaltered in its scope, steps, and procedures.

    In the WP 5D Plenary, one Administration requested that for clarity and transparency, and to assist further discussions, that the two alternate views provided on the SharePoint during the course of the 31 bis meeting (based on contributions to meetings Nos. 31 and 31 bis) be referenced in the Chairman’s Report. The two views are Indian Way Forward (provided by TSDSI) and Summary of a Proposed IMT-2020 VVV Way Forward (AT&T v3 2-14-19) (provided by AT&T).
    ………………………………………………………………….
    Doc. IMT-2020/YYY Input Submissions Summary

    Based on the input contributions, the working document towards an acknowledgment template was further developed. This acknowledgement is to be developed for each candidate technology submission that ITU-R WP 5D determines is a “complete” submission in Step 3. This template also contains a checklist which could assist in determination of “completeness. This document will need to be completed at Meeting #32 to capture the final RIT/SRIT submissions submitted from the proponents.
    …………………………………………………………………………………………..
    ITU-R Working Party 5D Workshop on IMT-2020 Terrestrial Radio Interfaces Evaluation

    WP 5D will hold a workshop on IMT-2020 focussing on the evaluation of the candidate terrestrial radio interfaces in conjunction with the 33rd meeting in December 2019 (shifted from the prior plan of holding this at Meeting #32), in which interim evaluation reports are expected. This will facilitate the possibility on the IEGs to understand the details of the proposed candidate technologies, and to interact with WP 5D and other IEGs participating in the ITU-R evaluation process on IMT 2020. This workshop is a continuation of the previous workshop on IMT-2020 held in 2017, Munich, which addressed the process, requirements, and evaluation criteria for IMT-2020 as well as views from proponents on the developments on IMT-2020 radio interface(s) and IEGs activities.
