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

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

  1. 3GPP 5G – Briefing for Evaluation Groups
    October 27, 2018 by Kevin Flynn Marketing and Communications Officer, 3GPP

    This week’s 3GPP Workshop on 5G NR, hosted by the European Commission, has been a comprehensive briefing from the key experts in 3GPP for the benefit of the official Independent Evaluation Groups (IEGs), who’s job it will be to report to the International Telecommunications Union (ITU) on whether the 3GPP system for 5G meets the performance requirements (in ITU-R M.2412) for an IMT-2020 technology.

    IMT stands for International Mobile Telecommunications, the term is used by the ITU to describe generations of radio interface standards for mobile systems. The latest member of the IMT family is IMT-2020 which calls for support for enhanced mobile broadband (eMBB) and for new ‘use cases’ that require massive machine-type communications (mMTC) and ultra-reliable and low latency communications (URLLC).

    These objectives reflect perfectly 5G research project’s pre-standards work and also the priorities for 3GPP work from Release 15 onwards. It is a little bit of ‘chicken and egg’ in terms of which came first, but the alignment between IMT-2020, 5G R&D and the 3GPP work plan is an important achievement, which will help greatly at the World Radiocommunication Conference 2019, where deliberations on additional spectrum in support of IMT will take place.

    In closing the 3GPP Workshop, Balazs Bertenyi concluded that – based on the results presented – there is a high level of confidence in the community that 3GPP’s submission to IMT-2020 will meet the ITU requirements. He asked all of the Independent Evaluation Groups to contact the 3GPP leadership and experts directly at any time in the process, to build on the dialogue started in Brussels this week.

  2. 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.

  3. Balazs Bertenyi, TSG RAN Chairman: The 3GPP non-standalone (NSA) 5G radio specifications, which means that you need an LTE anchor and besides that LTE anchor, you have the 5G NR cell, but you basically do your control plane & control plane communications through LTE and you boost the user data capacity through 5G NR and the new radio technology.
    What we have to recognize is that to make the full 5G vision a reality takes time, it takes multiple phases, it takes multiple [3GPP] releases – just as it did with LTE. So, the full 5G vision is really one with the multiple pillars that guide the overall system development for the next ‘x’ number of years.
    So, this is where the slight disconnect comes from “OK, 5G’s wonderful, but the first release only provides mobile broadband”, but what I think we have to recognise is that you cannot fulfil the full vision [of 5G] in one go. You have to start somewhere and you obviously want to start at an area and at a set of features that you can deploy. Otherwise, how would you gain experience with the new technology?

    From autonomous driving, to all of those industry verticals that we want to target with our technologies. That is really what will make 5G a success, we cant be constrained by the LTE footprint, we have to go way beyond that. That’s the only way that we can make 5G a success.
    ……………………………………………………………………………………………………..

    Erik Guttman, TSG SA Chairman: The 5G system is being developed largely as a new 5G core network and all of the components of that network are being considered – both in terms of the functionality they will provide for the NR and other accesses, but also in interaction with the EPC (Evolved packet core) and the entire 4G system. We are going to have compatibility going forward, as people adopt the new technology.

    The new 5G system features capabilities that will allow for orchestration of virtualization, as the components are redesigned to offer a very cleanly separated control plane and user plane – It adopts an internal signalling architecture that’s novel. So, rather than following distinct paths it is a service based architecture, though it support all of the procedures and mechanisms needed to provide mobile telecommunications, these same capacities can be used for other services that can be offered by operators, in the future.
    I think that we are in very good shape for the months to come and it will be an exciting challenge to get through both phase 1 and phase 2 of this initial 5G process and I am very confident that we can achieve the targets that we set out too – for IMT-2020 and even exceed many of those goals.

  4. 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

  5. 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…”
