ATIS endorses 3GPP IMT 2020 RIT submission to ITU-R WP 5D; sees no need for separate LMLC India national option

IMT-2020/VVV: “Process, use of the Global Core Specification (GCS), references, and related certifications in conjunction with Recommendation ITU-R M.[IMT 2020.SPECS]”

From Alliance for Telecommunications Industry Solutions (ATIS):     ATIS Insights

The 3GPP candidate radio-interface technology (RIT) for IMT-2020 (or 5G as it is known commercially) has demonstrated via the current in-progress submissions (including initial self‑evaluations to ITU-R WP 5D) that it is capable of meeting and, in fact, exceeding the requirements and evaluation criteria of IMT-2020 as expressed in Reports ITU-R M.2410 (requirements), ITU-R M.2411 (submission), and ITU-R M.2412 (evaluation), which were published in November 2017. It is widely anticipated that the 3GPP specifications in Release 15 and Release 16 will meet the futuristic vision of IMT-2020, as expressed in Recommendation ITU-R M.2083 for both developed and developing countries.

One national need (expressed by India) was for capabilities to permit low mobility large cell (LMLC) deployments. This need was, in fact, part of the submissions to WP 5D in 2016 and 2017, which drove the ITU-R Performance requirements, the ITU-R evaluation criteria/scenarios and hence the 3GPP specifications in Release 15 to be suitably modified to accommodate LMLC needs, thus illustrating the success of working within the framework of the current 3GPP process. Additionally, through the use of the established process, currently familiar to the entire ITU membership, a “national need” was recognized to actually be a global need in both ITU and in 3GPP. As such, the added technical capability can take advantage of the economies of scale afforded to a global marketplace. It is further noted that in technical submissions so far received by ITU-R WP 5D from 3GPP that this requirement for LMLC is indeed satisfied by the 3GPP technology capabilities already included in Release 15 published in September 2018.

ATIS urges that ITU-R Members, relevant external organizations, and others work within the established ITU-R IMT process and within the process established in the respective external organizations engaged in the development of IMT (and 5G) in order to ensure that IMT remains a unified and global technology with strong industry and governmental support. Only in this way, avoiding the division of the technical underpinnings, permits taking full advantage of the economies of scale to permit IMT-2020 to be available to the widest extent to ensure a globally-connected society at all strata, addressing both business and societal needs, while ensuring that IMT is technically capable of continuing global interoperability and roaming. The entire wireless industry and wireless user community will benefit from a single global standard; fragmentation of the standard reduces the benefits of a global ecosystem and diminishes the ITU IMT-2020 vision.
It will be very interesting to see how India’s TSDSI delegation to ITU-R WP 5D responds to this ATIS contribution.

India’s TSDSI Backgrounder: 

Global Activities of Telecommunications Standards Development Society India (TSDSI):
a) ITU-R:
TSDSI members’ proposal on Low Mobility Large Cell (LMLC) configuration has been included as a mandatory test configuration under the Rural eMBB test environment in IMT 2020 Technical Performance Requirements (TPR) in ITU-R with an enhanced Inter Sire Distance (ISD) of 6 km. Incorporation of LMLC in IMT2020 will help address the requirements of typical Indian Rural settings and will be a key enabler for bridging the rural-urban divide with 5G rollouts.

TSDSI’s initial proposal on candidate Radio Interface technology (RIT/SRIT) for IMT 2020 technologies, related to improving coverage and spectral efficiency performance, has been accepted in the WP 5D meeting #30 held in Cancun Mexico.

b) 3GPP:
TSDSI is Organizational Partner of 3GPP along with six other Regional Standardisation bodies. This entitles TSDSI members to become individual members of 3GPP through TSDSI and to take their IP into the global arena. Membership of 3GPP enables members to contribute in the development of upcoming standards such as 5G.

  1. 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…”

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

    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.
