    – SWG IMT Specifications (Chair: Mr. Yoshinori ISHIKAWA)
    – SWG Out of band emissions (Chair: Mr. Uwe LÖWENSTEIN)
    – SWG Radio Aspects (Chair: Mr. Marc GRANT, AT&T)
    ……………………………………………………………………………………….
    IMT-2020 submission:

    This meeting received updated information related to the proposal of candidate IMT-2020 radio interfaces from TSDSI (Doc. 5D/1138). SWG Coordination reviewed this contribution; and the respective IMT-2020 documents were revised accordingly.

    Preparation of IMT-2020 evaluation workshop:

    SWG Coordination discussed a received contribution on this subject (Doc. 5D/1131), and arrangement of future WP 5D meetings as well as the overall progress of IMT-2020 work. It’s decided to move the physical workshop from the 32nd WP 5D meeting to the 33rd WP 5D meeting to be held in December 2019 in Geneva. A draft liaison statement was developed (5D/TEMP/706(Rev.1)) to inform the registered Independent Evaluation Groups (IEGs) and GCS proponents about the workshop arrangement.

    IMT-2020 evaluation:

    This meeting received an evaluation report of the (S)RIT submissions of 3GPP from the IEG of TCOE (Doc. 5D/1179). SWG Evaluation reviewed this contribution and created a draft IMT-2020 document to record this evaluation report (5D/TEMP/689).

    Revision of Recommendation ITU-R M.1457:

    SWG IMT Specifications discussed revision of Recommendation ITU-R M.1457 and agreed not to set a concrete schedule for development of Revision 15 at this stage. It was also agreed that WP 5D would suspend the update of Recommendation ITU-R M.1457 until a request for updating the Recommendation is received from a GCS Proponent or a new IMT-2000 Radio Interface Technology proposal is submitted.

    IMT-2020/VVV:

    This meeting received five input contributions on the new IMT-2020 document, “Process and use of the Global Core Specification (GCS), references, and related certifications in conjunction with Recommendation ITU-R M.[IMT 2020.SPECS]”, from AT&T, Ericsson (Doc. 5D/1122), ATIS (Doc. 5D/1123), China (Doc. 5D/1128), Japan (Doc. 5D/1156) and Canada (Doc. 5D/1163). Those input documents were discussed together with the two carried forward documents of 5D/1071 (India) and 5D/1076 (China, Korea, Japan) at SWG IMT Specifications.
    However, the meeting did not conclude on some important issues like “Importance of the Global commonality / National or Regional flexibilities in technology part of RIT/SRIT” and “Usage of GCS and DIS”. No working document was created at this meeting. It was decided to carry forward all the input contributions to next meeting for further discussion.

    Synchronization of multiple IMT-2020 TDD networks:

    After reviewing and discussion on the received contribution (Doc. 5D/1134) from China, SWG Radio Aspects agreed to study synchronization operation of multiple IMT-2020 TDD networks. A work plan document was developed (5D/TEMP/674(Rev.1)).

  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. 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.

  8. SUMMARY OF ITU-R WORKING PARTY 5D WORKSHOP ON “IMT-2020 TERRESTRIAL RADIO INTERFACES EVALUATION”

    Working Party 5D (WP 5D) held a workshop on “IMT-2020 Terrestrial Radio Interfaces Evaluation” on 10 and 11 December 2019, with around 100 participants.
    The objectives of the workshop were:
    – to promote information sharing on IMT-2020;
    – to facilitate dialogue within ITU-R WP 5D and amongst the proponents as well as the proponents as well as the evaluation groups. The convener opened the workshop with remarks on its importance to promote efficient and intensive dialogue and discussion amongst the proponents and Independent Evaluation Groups, facilitating the IMT-2020 radio interface development process and by noting that each Independent Evaluation Group is required to submit its final evaluation report in February 2020. In the morning of the first day, the proponents of IMT-2020 terrestrial radio interfaces (3GPP Proponent, China, Korea, ETSI TC DECT, Nufront and TSDSI) presented their technologies and self-evaluation reports, followed by Q&A for technical clarifications and observations on future consensus building. During the course of the afternoon ten registered Independent Evaluation Groups presented their organization, evaluation methods, proposed technologies under evaluation, summary of interim evaluation reports submitted to WP 5D #33 meeting and so forth. There were observations and questions on the interim evaluation reports from proponents and other Independent Evaluation Groups. Some of the Independent Evaluation Groups had posted questions to proponents in the “Evaluation Groups discussion area” and it is encouraged to use this tool further to facilitate communication among the interested parties. The workshop session in the morning on the second day was a joint session with SWG Evaluation and SWG Coordination, in which the interim reports submitted to WP 5D #33 meeting were considered in detail. The objectives of the workshop were well achieved, and all the presentations made during the workshop can be found on the ITU-R WP 5D.
