Meeting schedule

The following table shows the proposed meeting dates for Working Party 5D following on WRC‑15. Some adjustment of these dates might be required to accommodate availability of facilities at specific venues. Every effort will be made to keep these dates as listed. Please check the ITU website in case meeting details have changed. (http://www.itu.int/events/monthlyagenda.asp?lang=en)

………………………………………………………………………………………………………………………………..

Work with involved organizations, including research entities:

The strategy for ITU-R WP 5D going forward is to gather information from the organizations involved in the global research and development and those that have an interest in the future development of IMT and to inform them of the framework and technical requirements in order to build consensus on a global level.

ITU-R WP 5D can play an essential role to promote and encourage these research activities towards common goals and to ensure that information from the WP 5D development on the vision, spectrum issues, envisioned new services and technical requirements are widespread among the research community. In the same manner, WP 5D encourages inputs from the external communities involved in these research and technology developments.

It is evident that continuing dialogue between the ITU and the entities taking part in research is a key to the continuing success of the industry in advancing and expanding the global wireless marketplace.

Working Party 5D, as is the case with all ITU organizations, works from input contributions submitted by members of the ITU. In order to facilitate receipt of information from external entities who may not be direct members of ITU, the Radiocommunication Bureau Secretariat may be considered as the point of interface, in accordance with Resolution ITU-R 9‑5.

The following major activities are foreseen to take place outside of the ITU, including WP 5D, in order to successfully complement the WP 5D work:

– research on new technologies to address the new elements and new capabilities of IMT‑2020;

– the ongoing development of specifications for IMT and subsequent enhancements.

The following table provides the schedule of when approval of the planned major deliverables will be achieved following the procedures of WP 5D.

…………………………………………………………………………………………………………………………………

Detailed timeline and process for Technology related work stream towards IMT-2020:

Working Party 5D has developed a work plan, timeline, process and required deliverables for the future development of IMT, necessary to provide by 2020 timeframe, the expected ITU-R outcome of evolved IMT in support of the next generation of mobile broadband communications systems beyond IMT-Advanced.

Circular Letter(s) are expected to be issued at the appropriate time(s) to announce the invitation to submit formal proposals and other relevant information.

It has been agreed that the well-known process and deliverable formats utilized for both IMT-2000 and IMT-Advanced should be utilized also for IMT-2020 and considered as a “model” for the IMT‑2020 deliverables to leverage on the prior work.

…………………………………………………………………………………………………………………

Dates have been decided for RA-19 (21-25 October 2019) and WRC-19 (28 October – 22 November 2019).

The WP 5D #32 (July) is the main meeting for year 2019.

The WP 5D #33 is to be held in December with a focus on the evaluation process (WG Technology Aspects).

If needed there is an opportunity for expert meeting to focus on preparation towards WRC-19 (WG General Aspects and WG Spectrum Aspects) prior to the WP 5D #32 (July).

Timeline for IMT 2020 (5G) Radio Access Recommendations + Evaluation Methodology

Introduction:

This article was written based on the ITU-R WP5D Niagara Falls, Canada meeting that concluded last week.  We attempt to present the true picture for standardizing IMT 2020 (5G) Radio Interface Technologies (RITs – aka Radio Access Networks or Radio Access Interfaces).

We don’t mention 3GPP release 15 (“5G” features over a LTE network) or 16 (pure 5G- no LTE) which will provide different levels of “5G” support.  Those specs might be submitted to ITU-R WP 5D for their consideration, based on the IMT 2020 RIT Evaluation methodology described in item 2. below.

Global carriers that have announced 5G specs and trials will likely have to do a major upgrade to their “5G” base stations to support the ITU-R IMT 2020 RIT specifications to be completed at the end of 2020 as per item 1. below.  It’s a mystery (to me and other IEEE members on the ComSocSCV email discussion group) as to what companies will provide the pre-standard “5G” handsets and other mobile/fixed end point devices that will have to be upgraded or replaced completely when standardized 5G is finalized in late 2020.

Note: SK Telecom said that’s not a problem as mobile device refresh/replace time is 18 months, so pre-standard 5G handsets will be obsolete when standardized 5G is finally deployed.

…………………………………………………………………………………………………………………………………….

2.  Key Sections of Evaluation of IMT 2020 Radio Interfaces (from new ITU-R WP5D draft report):

Scope:

This Report provides guidelines for the procedure, methodology and the criteria (technical, spectrum and service) to be used in evaluating the candidate IMT-2020 radio interface technologies (RITs) or Set of RITs (SRITs) for a number of test environments. These test environments are chosen to simulate closely the more stringent radio operating environments. The evaluation procedure is designed in such a way that the overall performance of the candidate RITs/SRITs may be fairly and equally assessed on a technical basis. It ensures that the overall IMT‑2020 objectives are met.

This Report provides, for proponents, developers of candidate RITs/SRITs and independent evaluation groups, the common evaluation methodology and evaluation configurations to evaluate the candidate RITs/SRITs and system aspects impacting the radio performance.   This Report allows a degree of freedom so as to encompass new technologies. The actual selection of the candidate RITs/SRITs for IMT-2020 is outside the scope of this Report.

The candidate RITs/SRITs will be assessed based on those evaluation guidelines. If necessary, additional evaluation methodologies may be developed by each independent evaluation group to complement the evaluation guidelines. Any such additional methodology should be shared between independent evaluation groups and sent to the Radiocommunication Bureau as information in the consideration of the evaluation results by ITU-R and for posting under additional information relevant to the independent evaluation group section of the ITU-R IMT-2020 web page (http://www.itu.int/en/ITU-R/study-groups/rsg5/rwp5d/imt-2020/Pages/submission-eval.aspx)

Evaluation guidelines:

IMT-2020 can be considered from multiple perspectives: users, manufacturers, application developers, network operators, service and content providers, and, finally, the usage scenarios – which are extensive. Therefore candidate RITs/SRITs for IMT-2020 must be capable of being applied in a much broader variety of usage scenarios and supporting a much broader range of environments, significantly more diverse service capabilities as well as technology options. Consideration of every variation to encompass all situations is, however, not possible; nonetheless the work of the ITU-R has been to determine a representative view of IMT‑2020 consistent with the process defined in Resolution ITU-R 65, Principles for the process of future development of IMT‑2020 and beyond, and the key technical performance requirements defined in Report ITU-R M.[IMT-2020.TECH PERF REQ] – Minimum requirements related to technical performance for IMT-2020 radio interface(s).

The parameters presented in this Report are for the purpose of consistent definition, specification, and evaluation of the candidate RITs/SRITs for IMT-2020 in ITU-R in conjunction with the development of Recommendations and Reports such as the framework and key characteristics and the detailed specifications of IMT-2020. These parameters have been chosen to be representative of a global view of IMT-2020 but are not intended to be specific to any particular implementation of an IMT-2020 technology. They should not be considered as the values that must be used in any deployment of any IMT-2020 system nor should they be taken as the default values for any other or subsequent study in ITU or elsewhere.Further consideration has been given in the choice of parameters to balancing the assessment of the technology with the complexity of the simulations while respecting the workload of an evaluator or technology proponent.

This procedure deals only with evaluating radio interface aspects. It is not intended for evaluating system aspects (including those for satellit system aspects).

The following principles are to be followed when evaluating radio interface technologies for IMT‑2020:
− Evaluations of proposals can be through simulation, analytical and inspection procedures.
− The evaluation shall be performed based on the submitted technology proposals, and should follow the evaluation guidelines, using the evaluation methodology and the evaluation configurations defined in this Report.
− Evaluations through simulations contain both system-level and link-level simulations. Independent evaluation groups may use their own simulation tools for the evaluation.
− In case of evaluation through analysis, the evaluation is to be based on calculations which use the technical information provided by the proponent.
− In case of evaluation through inspection the evaluation is to be based on statements in the proposal.

The following options are foreseen for proponents and independent external evaluation groups doing the evaluations:

− Self-evaluation must be a complete evaluation (to provide a fully complete compliance template) of the technology proposal.
− An external evaluation group may perform complete or partial evaluation of one or several technology proposals to assess the compliance of the technologies with the minimum requirements of IMT-2020.
− Evaluations covering several technology proposals are encouraged.

6. Overview of characteristics for evaluation
The characteristics chosen for evaluation are explained in detail in Report ITU-R M.[IMT‑2020.SUBMISSION −Requirements, evaluation criteria and submission templates for the development of IMT‑2020], § 3, including service aspect requirements, spectrum aspect requirements, and technical performance requirements , the last of which are based on Report ITU‑R M.[IMT-2020.TECH PERF REQ]. These are summarized in Table 6-1, together with their high level assessment method:
− Simulation (including system-level and link-level simulations, according to the principles of the simulation procedure given in § 7.1).
− Analytical (via calculation or mathematical analysis).
Inspection (by reviewing the functionality and parameterization of the proposal).

7. Evaluation methodology
The submission and evaluation process is defined in Document IMT-2020/2 − Submission, evaluation process and consensus building for IMT-2020.

Evaluation should be performed in compliance with the technical parameters provided by the proponents and the evaluation configurations specified for the test environments in § 8.2 of this Report. Each requirement should be evaluated independently, except for the average spectral efficiency and 5th percentile user spectral efficiency – both of which criteria shall be assessed jointly using the same simulation; consequently, the candidate RITs/SRITs shall fulfil the corresponding minimum requirements jointly.

Furthermore, the evaluation parameters used for the system-level simulation used in the mobility evaluation should be the same as the parameters used for system-level simulation for average spectral efficiency and 5th percentile user spectral efficiency.

The evaluation methodology should include the following elements:
1 Candidate RITs/SRITs should be evaluated using reproducible methods including computer simulation, analytical approaches and inspection of the proposal.
2 Technical evaluation of the candidate RITs/SRITs should be made against each evaluation criterion for the required test environments.
3 Candidate RITs/SRITs should be evaluated based on technical descriptions that are submitted using a technologies description template

In order for the ITU to be in a position to assess the evaluation results of each candidate RIT/SRIT, the following points should be taken into account:
− Use of unified methodology, software, and data sets by the evaluation groups wherever possible, e.g. in the area of channel modelling, link-level simulation, and link-to-system-level interface.
− Evaluation of multiple proposals using a single simulation tool by each evaluation group.
Evaluations of average spectral efficiency, 5th percentile user spectral efficiency, peak spectral efficiency, user experienced data rate, area traffic capacity, peak data rate, mobility, reliability, and connection density of candidate RITs/SRITs should take into account the Layer 1 and Layer 2 overhead information provided by the proponents.

Editor’s Note:

While Verizon [1] and many other wireless network operators plan to roll out their “5G” services between 2018 and 2020, that will be in ADVANCE OF THE ITU-R IMT 2020 “5G” standard.  We believe these “5G” roll-outs are extremely negative for the REAL market for standardized “5G,” which won’t begin till 2021 at the earliest.

Note 1.  According to Light Reading, a Verizon executive said that the operator’s home-brewed fixed 5G service will get up in running in 2018 but that he doesn’t expect true mobile 5G to arrive until 2020.

John Stratton, executive vice president and president of operations for Verizon Communications Inc., talking at the Deutsche Bank 25th Annual Media & Telecom Conference in Florida, said that Verizon will deliver fixed 5G in 2018. It is working on customer trials in 11 US cities now. (See Verizon Fixed 5G Tests to Top 3Gbit/s? and Verizon to Start Fixed 5G Customer Trials in April.)

Stratton promised a “meaningful commercial deployment of 5G” in 2018 from Verizon. He was cagey about what exact services the fixed system will provide, but it seems clear that a wireless alternative to cable/DSL services is high on Verizon’s priority list.

“The way we’re thinking about 5G… the ability to leverage the full scale of our business is an important factor,” Stratton added.

The customer trials, Stratton says, will allow Verizon to better understand the signal propagation characteristics of the fixed 5G system and “the load per node.” Verizon has previously said that it has been testing at ranges of up to 1,500 feet in diverse environments for its fixed option.

This document describes the process and activities identified for the development of the IMT‑2020 terrestrial components radio interface Recommendations.

1.  Time schedule

The time schedule described below applies to the first invitation for candidate RITs (Radio Interface Technologies) or SRITs (Set of Radio Interface Technologies). Subsequent time schedules will be decided according to the submissions of proposals.

Submission of proposals may begin at 28^th meeting of Working Party 5D (WP 5D) (currently planned to be 3-11 October 2017) and contribution to the meeting needs to be submitted by 1600 hours UTC, 7 calendar days prior to the start of the meeting. The final deadline for submissions is 1600 hours UTC, 7 calendar days prior to the start of the 32^nd meeting of WP 5D in July 2019. The evaluation of the proposed RITs and SRITs by the independent evaluation groups and the consensus-building process will be performed throughout this time period and thereafter. The detailed schedule can be found in Figure 1.

2             Process

2.1              General

Resolution ITU-R 65 on the “Principles for the process for future development of IMT for 2020 and beyond” outlines the essential criteria and principles that will be used in the process of developing the Recommendations and Reports for IMT-2020, including Recommendation(s) for the radio interface specification.

Recommendation ITU-R M.2083, IMT Vision – “Framework and overall objectives of the future development of IMT for 2020 and beyond” identifies three usage scenarios for IMT-2020 and envisions a broad variety of capabilities, tightly coupled with intended usage scenarios and applications for IMT-2020, resulting in a great diversity/variety of requirements. Recommendation ITU-R M.2083 also identifies the capabilities of IMT-2020, recognising that they will have different relevance and applicability for the different use cases and scenarios addressed by IMT‑2020, some of which are currently not foreseen. In addition, IMT-2020 can be applied in a variety of scenarios, and therefore different test environments are to be considered for evaluation purposes.

A test environment is defined as the combination of usage scenario and geographic environment as described in the draft new Report ITU-R M.[IMT-2020.EVALUATION]

2.2              Detailed procedure

The detailed procedure is illustrated in Figure 2 and is described below. Some activities are external to ITU-R and others are internal.

IMT-2020 terrestrial component radio interface development process

Step 1 – Circular Letter to invite proposals for radio interface technologies and evaluations

The ITU Radiocommunication Bureau, through Circular Letter 5/LCCE/59, invites the submission of candidate RITs or SRITs addressing the terrestrial component of IMT-2020. Addenda to the Circular Letter provide further details on the invitation for submission of proposals (including technical performance requirements, evaluation criteria and template for submission of candidate technologies).

This Circular Letter and its Addenda also invite subsequent submission of evaluation reports on these candidate RITs or SRITs by registered independent evaluation groups in addition to the initial evaluation report endorsed by the proponent.

Step 2 – Development of candidate RITs or SRITs

In this step, which is typically external to ITU-R, candidate terrestrial component RITs or SRITs are developed to satisfy a version of the minimum technical performance requirements and evaluation criteria of IMT-2020 currently in force (as defined in Resolution ITU-R 65, resolves 6 g)) that will be described in the Draft New Report ITU-R M.[IMT‑2020.SUBMISSION][4].

The required number of test environments for an RIT or SRIT to be fulfilled is as follows:

An RIT needs to fulfil the minimum requirements for at least three test environments; two test environments under eMBB and one test environment under mMTC or URLLC.

An SRIT consists of a number of component RITs complementing each other, with each component RIT fulfilling the minimum requirements of at least two test environments and together as an SRIT fulfilling the minimum requirements of at least four test environments comprising the three usage scenarios.

Step 3 – Submission/reception of the RIT and SRIT proposals and acknowledgement of receipt

The proponents of RITs or SRITs may be Member States, Sector Members, and Associates of ITU‑R Study Group 5, or other organizations in accordance with Resolution ITU-R 9-5.

The submission of each candidate RIT or SRIT must include completed templates (these templates will be provided in draft new Report ITU-R M.[IMT-2020.SUBMISSION], together with any additional inputs which the proponent may consider relevant to the evaluation. Each proposal must indicate the version of the minimum technical performance requirements and evaluation criteria of the IMT-2020 currently in force that it is intended for and make reference to the associated requirements.

The entity that proposes a candidate RIT or SRIT to the ITU-R (the proponent) shall include with it either an initial self-evaluation or the proponents’ endorsement of an initial evaluation submitted by another entity. The submission will not be considered complete without an initial self-evaluation or the proponents’ endorsement of an initial evaluation submitted by another entity.

Proponents and IPR holders should indicate their compliance with the ITU policy on intellectual property rights, as specified in the Common Patent Policy for ITU‑T/ITU-R/ISO/IEC available at: http://www.itu.int/ITU-T/dbase/patent/patent-policy.html (See Note 2 in Section A2.6 of Resolution ITU-R 1-7).

The Radiocommunication Bureau (BR) receives the submission of technical information on the candidate RITs and SRITs and acknowledges its receipt

Submissions should be addressed to the Counsellor for ITU-R Study Group 5, Mr. Sergio Buonomo ([email protected]). These submissions will be prepared as inputs to ITU-R Working Party

Working Party 5D (WP 5D) and will also be made available on the ITU web page for the IMT-2020 submission and evaluation process.

Step 4 – Evaluation of candidate RITs or SRITs by independent evaluation groups (mid 2018-2010)

Candidate RITs or SRITs will be evaluated. The ITU-R membership, standards organisations, and other organizations are invited to proceed with the evaluation. Organizations wishing to become independent evaluation groups are requested to register with ITU-R[6] preferably before the end of 2017. The independent evaluation groups are kindly requested to submit evaluation reports to the ITU-R. The evaluation reports will be considered in the development of the ITU-R Recommendation describing the radio interface specifications.

The evaluation guidelines, including criteria and test models, will be provided in draft new Report ITU‑R M.[IMT-2020.SUBMISSION] as announced in Circular Letter 5/LCCE/59 and its Addenda.

In this step the candidate RITs or SRITs will be assessed based on draft new Report ITU-R M.[IMT-2020.SUBMISSION]. If necessary, additional evaluation methodologies may be developed by each independent evaluation group to complement the evaluation guidelines in draft new Report ITU-R M.[IMT-2020.SUBMISSION]. Any such additional methodology should be shared between independent evaluation groups and sent to the BR for information to facilitate consideration of the evaluation results by ITU-R.

Coordination between independent evaluation groups is strongly encouraged to facilitate comparison and consistency of results, to assist ITU-R in developing an understanding of differences in evaluation results achieved by the independent evaluation groups and to form some preliminary consensus on the evaluation results. Consensus building is encouraged, such as grouping and/or syntheses by proponents in order to better meet the requirements of IMT-2020.

Each independent evaluation group will report its conclusions to the ITU-R. Evaluation reports should be addressed to the Counsellor for ITU-R Study Group 5, Mr. Sergio Buonomo ([email protected]).

The evaluation reports will be prepared as inputs to WP 5D and will also be made available on the ITU web page for the IMT-2020 submission and evaluation process.

The technical performance requirements and evaluation criteria for IMT-2020 are subject to reviews which may introduce changes to the technical performance requirements and evaluation criteria for IMT-2020. Proponents may request evaluation against any of the existing versions of the technical performance requirements and evaluation criteria that are currently in force for IMT-2020. 

Step 5 – Review and coordination of outside evaluation activities

WP 5D will act as the focal point for coordination between the various independent evaluation groups. In this step, WP 5D monitors the progress of the evaluation activities, and provides appropriate responses to problems or requests for guidance to facilitate consensus building.

Step 6 – Review to assess compliance with minimum requirements

In this step WP 5D makes an assessment of the proposal as to whether it meets a version of the minimum technical performance requirements and evaluation criteria of the IMT-2020 in draft new Report ITU-R M.[IMT-2020.SUBMISSION].

In this step, the evaluated proposal for an RIT/SRIT is assessed as a qualifying RIT/SRIT, if an RIT/SRIT fulfils the minimum requirements for the five test environments comprising the three usage scenarios.

Such a qualified RIT/SRIT will go forward for further consideration in Step 7.

According to the decision of the proponents, earlier steps may be revisited to complement, revise, clarify and include possible consensus-building for candidate RITs or SRITs including those that initially do not fulfil the minimum requirements of IMT-2020 that will be described in the draft new Report ITU-R M.[IMT-2020.SUBMISSION].

WP 5D will prepare a document on the activities of this step and assemble the reviewed proposals and relevant documentation. WP 5D will keep the proponents informed of the status of the assessment.

Such documentation and feedback resulting from this step can facilitate consensus building that might take place external to the ITU-R in support of Step 7.

Step 7 – Consideration of evaluation results, consensus building and decision

In this step WP 5D will consider the evaluation results of those RITs or SRITs that have satisfied the review process in Step 6.

Consensus building is performed during Steps 4, 5, 6 and 7 with the objective of achieving global harmonization and having the potential for wide industry support for the radio interfaces that are developed for IMT-2020. This may include grouping of RITs or modifications to RITs to create SRITs that better meet the objectives of IMT-2020.

An RIT or SRIT will  be accepted for inclusion in the standardization phase described in Step 8 if, as the result of deliberation by ITU-R, it is determined that the RIT or SRIT meets the requirements of Resolution ITU-R 65, resolves 6 e) and f) for the five test environments comprising the three usage scenarios. 

Step 8 – Development of radio interface Recommendation(s)- mid 2018 till Dec 2020

In this step a (set of) IMT-2020 terrestrial component radio interface Recommendation(s) is developed within the ITU-R on the basis of the results of Step 7, sufficiently detailed to enable worldwide compatibility of operation and equipment, including roaming.

This work may proceed in cooperation with relevant organizations external to ITU in order to complement the work within ITU‑R, using the principles set out in Resolution ITU-R 9-5.

Step 9 – Implementation of Recommendation(s)

In this step, activities external to ITU-R include the development of supplementary standards (if appropriate), equipment design and development, testing, field trials, type approval (if appropriate), development of relevant commercial aspects such as roaming agreements, manufacture and deployment of IMT-2020 infrastructure leading to commercial service.
