TSDSI’s 5G Radio Interface spec advances to final step of IMT-2020.SPECS standard

Telecommunications Standards Development Society of India (TSDSI)’s 5G Radio Interface Technology (RIT) has met step 7 of an 8 step process of ITU-R WP5D, thereby paving the way for its inclusion in the IMT-2020.SPECS.   That impressive accomplishment was achieved at the ITU-R WP5D virtual meeting #35e which concluded on July 9, 2020.  From the WP 5D Technology WG meeting report:  “The RIT proposed in IMT-2020/19(Rev.1) (TSDSI) also passed Step 7 as “TSDSI RIT.”

As a penultimate  step, the description of the TSDSI technology has been included in the draft IMT-2020 specification document.  The TSDSI RIT is specified in Annex III. of the draft IMT-2020.SPECS standard, which is expected to be finalized at the WP5D meetings to be held in October and November 2020. Final approval is expected at the ITU-R SG 5 meeting November 23-24, 2020.

The TSDSI 5G RIT specification was described in a July 5, 2019 IEEE Techblog post.  The ITU-R had earlier adopted the Low-Mobility-Large-Cell (LMLC) use case proposed by TSDSI as a mandatory 5G requirement in 2017. This test case addresses the problem of rural coverage by mandating large cell sizes in a rural terrain and scattered areas in developing as well as developed countries. Several countries supported this as they saw a similar need in their jurisdictions as well.

LMLC fulfills the requirements of affordable connectivity in rural, remote and sparsely populated areas. Enhanced cell coverage enabled by this spec, will be of great value in countries and regions that rely heavily on mobile technologies for connectivity but cannot afford dense deployment of base stations due to lack of deep fiber penetration,  poor economics and challenges of geographical terrain.

TSDSI successfully introduced an indigenously developed 5G candidate Radio Interface Technology (RIT), compatible with 3GPP’s 5G NR IMT-2020 RIT submission, at the ITU-R WP5D meeting in July, 2019 (as noted in the above referenced IEEE Techblog post).  TSDI’s RIT incorporates India-specific technology enhancements that can enable larger coverage for meeting the LMLC requirements. It exploits a new transmit waveform that increases cell range developed by research institutions in India (IIT Hyderabad, CEWiT and IIT Madras) and supported by several Indian tech companies. It enables low-cost rural coverage and has additional features which enable higher spectrum efficiency and improved latency.

From TSDSI:  Acceptance of TSDSI RIT as a 5G radio interface standard, a first for India, catapults India into the elite club of countries with expertise in defining global standards. It is a trailblazer that establishes India’s potential to deliver more such solutions that are appropriate to the specific requirements of the developing world and rely on indigenously developed technologies – Design Local, Deploy Global.

Addendum:  Overview of TSDSI RIT

TSDSI RIT is a versatile radio interface that fulfills all the technical performance requirements of IMT 2020 across all the different test environments. This RIT focuses on connecting the next generation of devices and providing services across various sectors. In particular, this RIT focuses on:

1. Enhanced spectral efficiency and broadband access

2. Low latency communication

3. Support millions of IOT devices

4. Power efficiency

5. High speed connectivity

6. Large Coverage (in particular for Rural areas)

7. Support multiple frequency bands including mmWave spectrum

While, the current specifications provide a robust RIT, the specification also provides a framework on which future enhancements can be supported, providing a future-proof technology. In the following sections, we provide a basic description of the RIT. The complete details of the RIT can be found in the specification document IMT-2020/20 (ITU TIES account required for access).

Introduction – IMT-2020.SPECS:

The forthcoming ITU-R recommendation “IMT-2020.SPECS” identifies the terrestrial radio interface technologies of International Mobile Telecommunications-2020 (IMT-2020) and provides the detailed radio interface specifications.

IMPORTANT: This new ITU-R standard will NOT include IMT 2020 non-radio aspects, such as 5G Core, Signaling, Network Slicing, Network Management/Maintenance, Security/Privacy, Fault Detection/Recovery, Codecs, Interworking, etc.

This new recommendation was developed by ITU-R WP5D (aka 5D) over the last five years. It consists of IMT 2020 (5G) Radio Interface Technologies (RIT) and Sets of Radio Interface Technologies (SRIT).

The final IMT-2020.SPECS is expected to be approved in late November 2020 at the ITU-R SGD meeting.  Here’s the related ITU-R meeting schedule for the remainder of 2020:

IMT 2020 RIT/SRIT submission status:

IMT 2020 RIT submissions from 3GPP/China/Korea [1.], TSDSI [2], DECT/ETSI, and Nufront are all being considered by 5D.  The latter two submissions have defined their own version of 5G New Radio (NR) as they do NOT use 3GPP’s 5G NR.

Note 1.  ATIS found the China and Korea IMT 2020 RIT/SRIT submissions to be technically identical to 3GPPs.

Note 2.  The TSDSI submission uses 3GPP’s 5GNR but also ADDS functional capability to support Low Mobility Large Cell (LMLC).

->Hence, there are potentially three different 5G NRs (as the basis for the respective RIT submissions) that may be standardized in IMT-2020.SPECS if the DECT/ETSI and Nufront submissions achieve final approval from WP5D. 5D requested additional work for both DECT/ETSI and Nufront RIT submissions before they can be progressed to the next step at 5D’s October 2020 meeting.  It remains to be seen if those submissions will be included in IMT-2020.SPECS.

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

Sidebar:

The “DECT-2020 NR” Radio Interface Technology (RIT) is designed to provide a slim but powerful technology foundation for wireless applications deployed in various use cases and markets. It utilizes the frequency bands below 6 GHz identified for International Mobile Telecommunication (IMT) in the ITU Radio Regulations.

The DECT-2020 radio technology includes, but is not limited to: Cordless Telephony, Audio Streaming Applications, Professional Audio Applications, consumer and industrial applications of Internet of Things (IoT) such as industry and building automation and monitoring, and in general solutions for local area deployments for Ultra-Reliable Low Latency (URLLC) and massive Machine Type Communication (mMTC) as envisioned by ITU-R for IMT-2020.

–>ETSI supports this DECT RIT mainly because of its URLLC capabilities, according to an email received from ETSI.

DECT-2020 NR is claimed by its sponsor to be a technology foundation is targeted for local area wireless applications, which can be deployed anywhere by anyone at any time. The technology supports autonomous and automatic operation with minimal maintenance effort. Where applicable, interworking functions to wide area networks (WAN). e.g. PLMN, satellite, fibre, and internet protocols foster the vision of a network of networks. DECT-2020 NR can be used as foundation for: Very reliable Point-to-Point and Point-to-Multipoint Wireless Links provisioning (e.g. cable replacement solutions);  Local Area Wireless Access Networks following a star topology as in classical DECT deployment supporting URLLC use cases, and Self-Organizing Local Area Wireless Access Networks following a mesh network topology, which enables to support mMTC use cases.

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

5D has approved the 3GPP and TSDSI RIT/SRIT submissions to be progressed to the next step at their recent e-Meeting which ended July 9, 2020.

However, there is still confusion (at least for this author) as to whether the China and Korea submissions (which were stated to be technically identical to 3GPP submissions) will also be progressed or merged with the 3GPP submissions.

–>If they are, it will pose a version change nightmare IMHO.

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

Overview of IMT-2020.SPECS:

The radio interface specifications in IMT-2020.SPECS detail the feature and parameters of IMT-2020. This Recommendation indicates that IMT-2020 enables worldwide compatibility, international roaming, and access to the services under all three usage scenarios, including enhanced mobile broadband (eMBB), massive machine type communications (mMTC) and ultra-reliable and low latency communications (URLLC).

The capabilities of IMT-2020 include:
– very high peak data rate;
– very high and guaranteed user experienced data rate;
– quite low air interface latency;
– quite high mobility while providing satisfactory quality of service;
– enabling massive connection in very high density scenario;
– very high energy efficiency for network and device side;
– greatly enhanced spectral efficiency;
– significantly larger area traffic capacity;
– high spectrum and bandwidth flexibility;
– ultra high reliability and good resilience capability;
– enhanced security and privacy.

These features enable IMT-2020 to address evolving user and industry needs.  The capabilities of IMT-2020 systems are being continuously enhanced in line with user and industry trends, and consistent with technology developments.

IMT-2020 Frequencies and Arrangements:

It’s vitally important to recognize that the frequencies to be used by IMT-2020 RITs, including five sets of mmWave bands, will NOT be in IMT-2020.SPECS.  Instead, they will be included in a revision of ITU-R M.1036 Recommendation (see below).  At their July 2020 meeting, 5D could not reach consensus on the draft revision of M.1036, because the Russian Federation expressed concerns about the current version of the revision.  Hence, this work item was carried over to 5D’s October 2020 meeting.

The highly touted and ultra hyped mmWave frequency arrangements (5 were recommended by WRC 19) have yet to be added to the M.1036 revision.  Frequency arrangements in the bands:  24.25-27.5 GHz, 37-43.5 GHz, 45.5-47 GHz, 47.2-48.2GHz, and 66-71 GHz will all use unpaired frequency arrangement with Time Division Duplexing (TDD) used to separate transmit and receive channels for full duplex communications.

The IEGs utilized the defined ITU-R evaluation methodology and criteria established in the relevant ITU-R Reports covering IMT-2020. ITU-R concluded that the IEGs had fulfilled their role in the process and that the inclusion of views from organizations external to the ITU‑R.

Considering the requirements, evaluation criteria and submission templates for the development of IMT-2020 included in Report ITU-R M.2411, the minimum requirements related to technical performance for IMT‑2020 radio interface(s) in Report ITU-R M.2410, and the guidelines for evaluation of radio interface technologies for IMT‑2020 are included in Report ITU‑R M.2412, the conclusions have been reached for each of the IMT-2020 RIT/SRITs submitted by 3GPP, China, Korea, TSDSI (India), DECT/ETSI, and Nufront.  Those detailed conclusions are beyond the scope of this article.

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

Overview of 3GPP’s radio interface technologies (E-UTRA/LTE and 5G NR):

The IMT-2020 RIT/SRIT specifications known as “5G” have been developed by 3GPP and consist of LTE and 5G NR Releases 15, 16, and beyond.

In 3GPP terminology, the term Evolved-UMTS Terrestrial Radio Access (E-UTRA) is also used to signify the LTE radio interface. 5G is a Set of Radio Interface Technologies (RITs) consisting of E-UTRA/LTE as one component RIT and (5G) NR as the other component RIT. Both components are designed for operation in IMT defined spectrum.

5G fulfills all technical performance requirements in all five selected IMT-2020 test environments : Indoor Hotspot – enhanced Mobile Broadband (eMBB), Dense Urban – eMBB, Rural – eMBB, Urban Macro – Ultra Reliable Low Latency Communication (URLLC) and Urban Macro – massive Machine Type Communication (mMTC).

5G also fulfills the service and the spectrum requirements. Both component RITs, NR and E-UTRA/LTE, utilize the frequency bands below 6 GHz identified for International Mobile Telecommunication (IMT) in the ITU Radio Regulations. In addition, the NR component RIT can also utilize the frequency bands above 6 GHz, i.e., above 24.25 GHz, identified for IMT in the ITU Radio Regulations. The complete set of standards for the terrestrial radio interface of IMT-2020 identified as 5G includes not only the key characteristics of IMT-2020 but also the additional capabilities of 5G both of which are continuing to be enhanced.

ITU-R WP5D’s conclusion on 3GPP’s 5G SRIT and 5G RIT is shown in the table below:

1 Developed by 3GPP as 5G, Release 15 and beyond (as indicated in Documents 5D/1215 and 5D/1216)

2 The NB-IoT part of IMT-2020/15 (China) candidate technology proposal is technically identical to the specifications for the NB-IoT part of IMT-2020/13 (3GPP SRIT).

3 Developed by 3GPP as 5G, Release 15 and beyond (as indicated in Documents 5D/1215 and 5D/1217)

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

The 3GPP 5G System (5GS) also includes specifications for its non-radio aspects, such as the core network elements (the Enhanced Packet Core (EPC) Network and 5G Core (5GC) Network), security, codecs, network management, etc. These non-radio specifications are not included in the so-called “Global Core Specifications (GCS)” of IMT-2020.

Support of Industry Verticals:

The E-UTRA/LTE and 5G NR component RITs from 3GPP support a diverse set of mobile broadband (eMBB) services and other so-called industry “verticals,” including URLLC, Industrial IoT, Automotive/V2X, Private Networks (NPN), and others. NR RIT supports in-band coexistence with NB-IoT and eMTC. For optimal support of specific verticals, the 5G NR RIT has been designed, or enhanced, with certain key features, or set of features.

A short summary of relevant NR RIT capabilities for a few industry verticals is provided below.

Ultra-Reliable and Low Latency Communications (URLLC) and Industrial IoT (IIoT): 

For support of Ultra-Reliable and Low Latency Communications services, some of the main features supported by the 5G NR RIT are:
• Logical Channel Priority (LCP) restrictions
• Packet duplication with DC or CA
• New QCI table for block error rate 10*-5
• Physical layer short transmission time interval (TTI)

From 3GPP Rel-16 onwards, URLLC and Industrial IoT use cases are further facilitated by:
• NR PDCP duplication enhancements,
• Prioritization/multiplexing enhancements,
• NR Time Sensitive Communications (TSC) related enhancements,e.g. Ethernet header compression, and
• Precise time information delivery

Factory Automation & “Industry 4.0”:

5G URLLC in Release 16 (RAN and 5G core) was said to improve link reliability by as much as 99.9999%.  These types of applications are best served by a coordinated multi-point (CoMP) approach that leverages multiple transmission and reception (multi-TRP) architecture to provide redundant communication paths with some degree of spatial diversity.

Vehicle-to-everything (V2X) communications:

From 3GPP Rel-16, NR RIT includes support of Vehicle-to-everything (V2X), mainly by means of NR sidelink communication over the PC5 interface, partly leveraging what was defined for E-UTRA V2X sidelink communication.

Sidelink transmission and reception over the PC5 interface are supported when the UE is inside NG-RAN coverage, irrespective of which RRC state the UE is in, and when the UE is outside NG-RAN coverage.

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

IMT-2020 Consensus Building and Decision by 5D:

– IMT-2020/15 (China) candidate technology proposal is technically identical to the IMT‑2020/14 (3GPP RIT) candidate technology proposal and NB-IoT part of IMT‑2020/13 (3GPP SRIT) candidate technology proposal;

– IMT-2020/16 (Korea) candidate technology proposal is technically identical to the IMT‑2020/14 (3GPP RIT) candidate technology proposal;

Additionally, consensus building has been performed 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. (?????)

As a result of the consensus building in ITU-R among the seven technology proposals, the following groupings are agreed by ITU-R:

– The SRIT proposed in IMT-2020/13 including NB-IoT part to which China (People’s Republic of) (NB-IoT part of IMT-2020/15) is technically identical, is identified in ITU as “3GPP 5G SRIT”1, developed by the Third Generation Partnership Project (3GPP), for Step 7 and subsequent IMT-2020 development.

– The RITs proposed in IMT-2020/14, NR part of IMT-2020/15 and IMT-2020/16 are grouped into the technology identified in ITU as “3GPP 5G RIT”2, developed by the Third Generation Partnership Project (3GPP), for Step 7 and subsequent IMT-2020 development.

Future IEEE Techblog posts on 3GPP Rel 16 and IMT 2020:

This author has been in dialog with 3GPP leaders via the 3GPP Marketing Communications Manager to accurately assess 3GPP Rel 16 completed work items related to 5G (both radio and non-radio aspects).  In particular, we are very much interested in the 3GPP Rel 16 URLLC specification, performance simulation(s), and performance testing (not yet started).  Only after independent performance testing will we know if the URLLC test implementation meets the required performance parameters specified by 3GPP and/or Minimum requirements related to technical performance for IMT-2020 radio interface(s) [ITU M.2410].

The IEEE Techblog Editorial Team is soliciting guest blog posts related to 3GPP Rel 16 and/or issues with IMT-2020.SPECS as well as other topics listed here.

New ITU-T SG13 Recommendations related to IMT 2020 and Quantum Key Distribution

by Leo Lehmann,  Chairman of ITU-T SG13 with background information and editing by Alan J Weissberger

Backgrounder:

ITU-T SG13 is the lead ITU-T study group on: future networks such as IMT-2020 networks (non-radio related parts), mobility
management, cloud computing, and trusted network infrastructure.  The work is assigned to questions of which the following are related to the non radio aspects of IMT 2020:

Q.6: Quality of service (QoS) aspects including IMT-2020 networks
Q.20: IMT-2020: Network requirements and functional architecture
Q.21: Network softwarization including softwaredefined networking, network slicing and orchestration
Q.22: Upcoming network technologies for IMT-2020 and future networks
Q.23: Fixed-mobile convergence including IMT-2020

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

ITU-T SG13 Chairman’s Summary:

The recent (since October 2019) published IMT 2020 (non radio) related recommendations from ITU SG13 are the following:

  • Y.3154 (Y.NetSoft-SSMO) Resource pooling for scalable network slice service management and orchestration in the IMT-2020 network.  [see below this article for SG13 liaison to GSMA related to Network Slicing]
  • Y.3108 (Y.IMT2020-CEF) Capability exposure function in the IMT-2020 networks
  • Y.3132  (Y.FMC-MM) Mobility management for fixed mobile convergence in IMT-2020 networks
  • Y.3133 (Y.FMC-CE) Capability exposure enhancement for supporting FMC (Fixed Mobile Convergence) in IMT-2020 networks
  • Y.3173 (Y.ML-IMT2020 -Intelligence-level) Framework for evaluating intelligence level of future networks including IMT-2020
  • Y.3174  (Y.ML-IMT2020 -Data-Handling) Framework for data handling to enable machine learning in future networks including IMT-2020
  • Y.3175 (Y.qos-ml-arc) Functional architecture of machine learning based quality of service assurance for the IMT-2020 network
  • Y.3154 (Y.NetSoft-SSMO) Resource pooling for scalable network slice service management and orchestration in the IMT-2020 network

Not directly related to IMT 2020, but generally related to network orchestration and optimization is Y.3652 (Y.bDDN-req) “Requirements of big data driven networking” as an useful new document in the Y.365x series.

In addition, SG13 has published two new recommendations for networks to support quantum key distribution (QKD) [1] :

  • Y.3800 (Y.QKDN_FR) Overview on networks supporting quantum key distribution
  • Y.3801 (Y.QKDN_req) Functional requirements for quantum key distribution networks
  • Y.3800 describes the basic conceptual structures of QKD networks as the first of a series of emerging ITU standards on network and security aspects of quantum information technologies. SG13 standards for QKD networks – networks of QKD devices and an overlay network – will enable the integration of QKD technology into large-scale ICT networks.

Complementing these activities SG17 standards provide recommendations for the security of these QKD networks.

Note 1.    Quantum key distribution (QKD) is a technology using quantum physics to secure the distribution of symmetric encryption keys which solves the problem of key distribution by allowing the exchange of a cryptographic key between two remote parties with information-theoretic security, guaranteed by the fundamental laws of physics. This key can then be used securely with conventional cryptographic algorithms.

The threats posed by quantum computing have a wide range of impacts since public key algorithms such as Rivest-Shamir-Adleman (RSA) and elliptic curve cryptography (ECC) are widely used in various security protocols and applications. How to design quantum-safe cryptography that can resist quantum computing attacks is a problem that must be considered for ICT systems to ensure security in the “quantum era”.

In general, there are three possible means to combat quantum computing attacks:

  1. Enhancement of current crypto system: Doubling the current key size can resist Grover’s algorithm which provides a quadratic speed-up for quantum search algorithms in comparison to search algorithms on classical computers. However, this is only suitable for symmetric key systems.

  2. Design of new public key system: Utilizing new mathematical problems which have not been cracked by current quantum algorithms, e.g., lattice-based and code-based cryptography algorithms, which are more often called post-quantum cryptography (PQC). However, even if those new mathematical problems might be proven as robust against known quantum algorithms, they will not be proven secure against quantum algorithms that might be created in the future.

  3. Use of QKD to replace public key based key exchange mechanism: The security of QKD is based on quantum physics principles, which can effectively avoid the threats caused by the increase of computational power or algorithmic “backdoors” faced by traditional public key algorithms. QKD is already proven as robust against quantum algorithms that might be created in the future.

According to Wikipedia, Quantum key distribution is only used to produce and distribute a key, not to transmit any message data. This key can then be used with any chosen encryption algorithm to encrypt (and decrypt) a message, which can then be transmitted over a standard communication channel. The algorithm most commonly associated with QKD is the one-time pad, as it is provably secure when used with a secret, random key. In real-world situations, it is often also used with encryption using symmetric key algorithms like the Advanced Encryption Standard algorithm.

Liaison Q & A between GSMA and ITU-T SG13 on Network Slicing – Important output liaison from March 2020 SG13 meeting:

Question #1: Network slicing is one of the main features of 5G networks and has been defined by 3GPP. GSMA NEST (NEtwork Slice Type) would like to understand how ServiceProfile from 3GPP TS 28.530 fits into IMT-2020 network slice configuration?

Question #3: What is the relationship between ITU-T NST (Network Slice Template) and GSMA GST (Generic network Slice Template) and 3GPP ServiceProfile?

Answer: ITU-T Q21/13 has recognized the necessity of translation processes from GSMA GST into 3GPP ServiceProfile. Q21/13 is studying the processes with the analysis of IMT-2020 use-cases, and trying to define useful parameters and information for the processes without overlap between SDOs.

Separately Network Slicing will be further defined in 3GPP Release 16.

Evaluation of IMT-2020 candidate technology submissions:

This 34th WP 5D meeting is a milestone of the IMT-2020 submission and evaluation process: Step 4 – Evaluation of candidate RITs or SRITs by independent evaluation groups.

Twelve Independent Evaluation Groups (IEGs) submitted to this meeting twenty-seven evaluation reports of all the candidate technology submissions. The meeting reviewed these evaluation reports, with participations of the IEGs, the proponents of candidate technology submissions and other participants. The Step 4 was completed with all the evaluation reports recorded.

Evaluation report summaries are captured in the respective documents (5D/TEMP/112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 125 and 126). The meeting also developed an overall summary – Summary of Step 4 of the IMT-2020 Process for Evaluation of IMT-2020 Candidate Technology Submissions (5D/TEMP/124), which also captures different views raised during the discussion at the meeting.

An addendum to the Circular Letter 5/LCCE/59 was developed to convey the completion of Step 4.

The meeting also made progress on the work of Document M.[IMT-2020.OUTCOME]. It was agreed to upgrade the working document to a preliminary draft new Report (5D/TEMP/111).

IMT-2020.SPECS

The work of M.[IMT‑2020.SPECS] continued at this meeting based on received contributions. The working document and the work plan were revised accordingly (5D/TEMP/41 and 40).

A draft liaison statement to potential GCS Proponents to request the inputs to 35th meeting was developed. It was noted that confirmation of the potential GCS Proponents can only be done after WP 5D takes a decision for Steps 6 & 7 on IMT-2020 RIT/SRIT at its 35th meeting.

Work items in SWG Radio Aspects

The meeting made progress on the work of Synchronization of multiple IMT-2020 TDD networks and the working document was updated (5D/TEMP/93).

A new working document is created to study terrestrial IMT for remote sparsely populated areas providing high data rate coverage – M.[IMT TERRESTRIAL BROADBAND REMOTE COVERAGE] (5D/TEMP/101).

The meeting also agreed to start work on future technology trends, and a work plan was developed (5D/TEMP/96).

iv) Start working on Report ITU-R M.[IMT-2020.OUTCOME].

v) Start working on Recommendation ITU-R M.[IMT-2020.SPECS].

During this meeting, WG Technology Aspects established three Sub-Working Groups (SWG):

–                 SWG Coordination (Chair: Mr. Yoshio HONDA)

–                 SWG Evaluation (Co-Chair: Ms. Ying PENG)

–                 SWG IMT Specifications (Chair: Mr. Yoshinori ISHIKAWA)

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

Review of updated materials of IMT-2020 submissions:

As per the agreed way forward at the 32nd WP 5D meeting regarding candidate IMT-2020 RIT/SRIT submissions of ETSI (TC DECT) and DECT Forum, Nufront and TSDSI, the respective proponents provided updated materials of their submissions on September 10th of 2019.

After review of these updated materials of submissions under the IMT-2020 Process Step 3 – Submission / reception of the RIT and SRIT proposals and acknowledgement of receipt, the meeting determined that the submissions of ETSI (TC DECT) and DECT Forum, Nufront and TSDSI are “complete” per Section 5 of Report ITU-R M.2411 (Requirements, evaluation criteria and submission templates for the development of IMT-2020).

Editor’s Note:  Also see ITU-R Report M.2412: Guidelines for evaluation of radio interface technologies for IMT-2020.

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

During the course of this review, documents for observations on the submissions were updated.

Review of interim evaluation reports:

A workshop on IMT-2020 terrestrial radio interfaces evaluation was conducted at beginning of this WP 5D meeting (Dec 10-11, 2019), where the registered independent evaluation groups presented their activities and findings. In addition, some independent evaluation groups also submitted interim evaluation reports. The meeting reviewed these contributions and recorded them.

Report ITU-R M.[IMT-2020.OUTCOME]:

The meeting created the draft detailed workplan and draft working document towards a prelimininary draft new Report ITU-R M.[IMT-2020.OUTCOME] which will collect outcomes from Step 4 to 7 in IMT-2020 development process. Those two documents were carried forward to the next meeting for further work.

Detailed schedule for development of IMT-2020.SPECS:

Detailed workplan for development of draft new Recommendation ITU-R M.[IMT-2020.SPECS] and its working document were developed in the meeting.  A related liaison statement to the external organizations was also developed.

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

Editor’s Note: 

IMHO, the IMT 2020.SPECS schedule is NOT realistic, mainly because there isn’t enough time for 5D WG Technology Aspects to evaluate 3GPPs expected Release 16 submission at their June 2020 meeting.  Note that China, Korea and India (TSDSI) have all based their IMT 2020 RIT submissions on 3GPP Release 15 “5G NR” data plane which must be enhanced in IMT 2020.SPECs to meet the ultra high reliability/ultra high latency performance requirements for both the data and control planes.

There are only two more WP 5D meetings in 2020 (see last section below) after the June 2020 5D meeting, yet a complete IMT 2020.SPECs must be submitted by Nov 23, 2020 to ITU-R SG 5 (5D’s parent) for approval.  If not, IMT 2020 will become IMT 2021 (or later if companion IMT 2020 recommendations have not been approved).  What good is it to have a 5G data plane without ultra low latency/ultra high reliability and a 4G (EPC) packet core?  With no 5G network management or 5G security specified (presumably by ITU-T)?

Specifically, what if the 5G Mobile Packet Core (3GPP 5GC), enhanced 5G control plane/signaling, 5G network management, 5G security, etc (all in 3GPP Release 16) are not completed in time to be considered by ITU-R or ITU-T in 2020?

Another danger is IMT 2020.SPECS revision control with multiple RIT submissions dependent on 3GPP 5G NR.  What if some proponents stick with Release 15 NR while others adopt Release 16 NR in July 2020?  And how can all the different proponent IMT 2020 RITs be harmonized to ensure interoperability and roaming?

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

Objective for the 34th WP 5D meeting – Feb 2020 in Geneva:

The key objectives of WG Technology Aspects for the 34th WP 5D meeting are as follows:

i) Review of external activities and evaluation reports of Independent Evaluation Groups.

ii) Complete evaluation reports summary (IMT-2020/ZZZ).

iii)    Continue working on a new Report ITU-R M.[IMT-2020.OUTCOME].

iv) Continue the work on “Over-the-air (OTA) TRP field measurements for IMT radio equipment utilizing AAS” based on the requested response from 3GPP and expected input from other organisations and administrations.

v) Continue working on revision of Recommendation ITU-R M.1457-14.

vi) Continue working on new Recommendation ITU-R M.[IMT-2020. SPECS]

Submitted by Ying Peng, Chair, SWG Evaluation

…………………………………………………………………………………………

M.[IMT-2020.SPECS]:

Under agenda item 4 (PDN Rec. ITU-R M.[IMT-2020.SPECS]), the meeting received two input contributions from Korea, Japan and China.

Both contributions proposed the detailed work plan for developing the new Recommendation ITU-R M.[IMT-2020.SPECS] and the working document towards a preliminary draft new Recommendation.

The meeting reviewed those proposals and discussed the work plan and contents for the working document and agreed the detailed work plan and the working document towards a PDNR (preliminary draft new report).

Detailed workplan and working document towards PDNR M. [IMT‑2020.OUTCOME]

The meeting created the draft detailed work plan and draft working document towards PDNR M.[IMT-2020.OUTCOME] based on the carried forward document and input contributions to this meeting. Two TEMP Documents were created accordingly and will be carried forward to the next meeting.

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

Meeting #33 also created a liaison statement to relevant External Organizations (RIT/SRIT Proponents, potential GCS Proponent(s) of IMT-2020) to request the inputs to 34th and 35th meetings in accordance with Doc. IMT-2020/21. WG-IMT Specification seeks approval of this liaison in WG Technology Aspects Plenary and WP 5D Plenary.

Workshop on IMT-2020 terrestrial radio interfaces evaluation (10 to 11 December 2019, Geneva, Switzerland):

ITU-R Working Party (WP) 5D started the evaluation process for Independent Evaluation Groups (IEGs) as of its 31st meeting in Oct. 2018, in conjunction with the ongoing IMT-2020 development under Step 3 and Step 4 of the IMT-2020 process.​

Working Party 5D has received, at its July 2019 meeting, several candidate technology submissions for IMT-2020 from six proponents, under Step 3 of the IMT-2020 developing process. ​

WP 5D held a workshop on IMT-2020, focusing on the evaluation of the candidate terrestrial radio interfaces at its 33rd meeting taking place December 2019 in Geneva, at which interim evaluation reports are expected. This will help the IEGs understand the details of the proposed candidate technologies, and interact amongst themselves as well as other WP 5D participants. This workshop is a continuation of the previous one 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 of IMT-2020 radio interfaces and activities of the IEGs.

December 12, 2019 UPDATE:

See Comment in box below this article for disposition of TSDSI, ETSI/DECT Forum, and Nufront IMT 2020 RIT self evaluations.  They have not “satisfactorily fulfilled Section 4.3 for the self-evaluation,” which means that the respective IMT 2020 RIT submissions will not be progressed at this time by WP 5D.

China ITU-R WP5D submission: work plan and working document for IMT-2020.SPECS

Introduction:

ITU-R WP 5D has received final submissions from 3GPP, Korea, China, ETSI/DECT Forum, TSDSI and Nufront; and then additional information for complementing the proposals of ETSI/DECT Forum, TSDSI and Nufront has been submitted by September 10th, 2019.

The draft new Recommendation ITU-R M.[IMT-2020.SPECS] (Detailed specifications of the terrestrial radio interfaces of International Mobile Telecommunications-2020 (IMT-2020)) should be developed from the 33rd 5D meeting (December 10-13, 2019) in Sub Working Group-IMT Specifications.  The schedule calls for completion of that recommendation at the December 2020 ITU-R WP5D meeting.

Editor’s Note:

As ITU-R WP5D reports to SG 5, they must complete IMT 2020.specs at their Nov 17-19, 2020 meeting so that they can forward it for approval to the next scheduled SG 5 meeting which takes place the following week – Nov 23-24 in Geneva. Failure to do that will result in IMT 2020.specs to not be approved by ITU-R till 2021.

q) that for some scenarios of IMT-2020 requiring bandwidths of at least 100 MHz, and up to 1 GHz, there would be a need to consider wideband contiguous spectrum above 6 GHz;

r) that IMT-2020 will realize the Internet of Things (IoT) by connecting a vast range of smart appliances, machines and other objects without human intervention;

s) that applicable areas of IMT-2020 and beyond are expected to be expanded further to various specific verticals industrial applications to facilitate the digital economy, e.g. e-manufacturing, e-agriculture, e-health, intelligent transport systems, smart city and traffic control, etc., which could bring requirements beyond current capabilities of IMT;

t) that IMT-2020 should be able to provide these capabilities without undue burden on energy consumption, network equipment cost and deployment cost to make future IMT sustainable and affordable;

u) that other capabilities may be also required for IMT-2020, which would make future IMT more flexible, reliable, and secure when providing diverse services in the intended usage scenarios,

recognizing that Resolution ITU-R 65 on the “Principles for the process of future development of IMT for 2020 and beyond” outlines the essential criteria and principles used in the process of developing the Recommendations and Reports for IMT-2020, including Recommendation(s) for the radio interface specification, noting that Report ITU-R M.[IMT-2020.OUTCOME] contains the outcome and conclusions of Steps 4 through 7 of the IMT-2020 process, including the evaluation and consensus building, and provides the characteristics of the IMT-2020 terrestrial radio interfaces for the first release of Recommendation ITU-R M.[IMT-2020.SPECS],

Preview of WRC‑19: Enabling Global Radiocommunications via Radio Frequency Spectrum and Satellite Orbit Resources

By Mario Maniewicz, Director of the ITU Radiocommunication Bureau

The ITU’s upcoming World Radiocommunication Conference 2019 (WRC‑19) will play a key role in shaping the technical and regulatory framework  for the provision of radiocommunication services in all countries, in space, air, at sea and on land. It will help accelerate progress towards meeting the Sustainable Development Goals (SDGs). It will provide a solid foundation to support a variety of emerging technologies that are set to revolutionize the digital economy, including the use of artificial intelligence, big data, the Internet of Things (IoT) and cloud services.

“The World Radiocommunication Conference, which opened today (October 28th), will address some of the leading-edge technological innovations set to play a pivotal role in tomorrow’s digital economy and the future development of services, systems and technologies,” said ITU Secretary-General Houlin Zhao, noting that digital inclusion provides the chance to improve the lives of millions across the world. “A transformative revolution in connectivity is in the making with immense implications for the trillion-dollar telecommunication and ICT industry and in advancing many of the United Nations SDGs.”

Every three to four years the conference revises the Radio Regulations (RR), the only international treaty governing the use of the radio-frequency spectrum and satellite orbit resources. The treaty’s provisions regulate the use of telecommunication services and, where necessary, also regulate new applications of radiocommunication technologies.

The aim of the regulation is to facilitate equitable access and rational use of the limited natural resources of the radio-frequency spectrum and the satellite orbits, and to enable the efficient and effective operation of all radio communication services.

WRC‑19 will be held in Sharm El-Sheikh, Egypt, from 28 October to 22 November 2019 and its agenda covers a wide range of radio- communication services (see examples at the end of this article).

The preparations for the conference include studies and discussions that take place in the ITU–R Study Groups, the Conference Preparatory Meeting, the ITU inter-regional workshops, and also within the regional groups. The very nature of the process and study cycle helps build consensus and facilitates the work of the conference, where final decisions are made. See the infographic for more information on the preparatory process.

Each World Radiocommunication Conference affects the future development of information and communication technologies (ICTs) in many ways, including:

    • Introducing and expanding access to the radio spectrum for new radiocommunication systems and applications;
    • Protecting the operation of existing radiocommunication services and providing the stable and predictable regulatory
      environment needed for future investments;
    • Avoiding the potential for harmful interference between radio services;
    • Allowing the provision of high-quality radiocommunications while protecting vital uses of the radio spectrum, particularly for distress and safety communications; and
    • Facilitating international roaming and increasing economies of scale, thereby making it possible for network and user
      devices to be more affordable.

2nd ITU Inter-regional Workshop on WRC-19 Preparation

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

Times of transformation:

Currently, billions of people, businesses, and devices are connected to the Internet. ICTs are transforming each and every aspect of our lives, from the way people interact and communicate to the way companies do business.

People expect instantaneous high-quality connectivity, whether stationary or on-the-move, in their homes or outside in a crowd.

Companies search for new ways to increase their business and operational efficiency, whether by monitoring the condition of equipment and conducting predictive maintenance, or by monitoring customer data to offer personalized solutions. The increasing need for a new underlying ecosystem will be made possible by utilizing a variety of complementary terrestrial and satellite technologies/services.

The fifth generation of mobile technology, International Mobile Telecommunications (IMT) 2020 (5G) promises to enhance the connectivity infrastructure that delivers high-speed networks to end users, carries the flow of information from billions of users and IoT devices, and enables a whole array of services to different industry verticals. Spectrum for 5G services will be one of the main topics of WRC‑19. More specifically, new allocations will be considered for the mobile service and identification for IMT of frequencies in the mm Wave bands (above 24 GHz).

In addition, satellite services aim at increasing connectivity, whether by providing access to broadband communications to unserved rural communities, or to passengers on aircrafts, on ships and on land, or by expanding backhaul of terrestrial networks.

WRC‑19 will address fixed and mobile satellite services, earth stations in motion, and will revise the assignment procedures pertaining to satellite networks.

Leveraging the economic opportunities brought by technology should be possible not only for some, but for all. One target of SDG No. 9 is to increase access to ICTs and strive to provide universal and affordable access to the Internet in least-developed countries by 2020.

Fortunately, new technological innovations support this goal. They aim at expanding broadband connectivity and telecommunication services to least-developed countries, underserved communities, rural and remote areas, including mountainous, coastal and desert areas.

Towards this end, WRC‑19 will consider spectrum for High-Altitude Platform Systems (HAPS) and will revise the regulatory framework for Non-Geostationary Satellite Systems (non-GSO). HAPS, operating in the stratosphere, can be used to provide fixed broadband connectivity for end users, and backhaul for mobile networks, thus increasing the coverage of these networks.

Constellations of non-GSO satellites aim at improving quality, increasing the capacity and reducing the costs of satellite services, which should enable satellite operators to bring market solutions that increase access to connectivity.

Times of uncertainty

These are times of transformation, but also of uncertainty. The number of natural disasters have increased considerably in the last decades: hurricanes, earthquakes, storms, floods, and fires. Climate change is a reality: we are experiencing heatwaves, and observing long-lasting glaciers melt.

Taking this into account, SDG No. 13 on climate action targets to strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries. To reach this target, several radiocommunication services offer the solution required to monitor, mitigate and adapt to these events.

Satellite communications, and in particular space sensing and Earth observation systems are used to monitor the state of the oceans and the conservation of forests. They can detect natural disturbances in the state of the atmosphere and provide accurate climate predictions.

Radiocommunication services are a crucial accelerator towards the achievement of all the SDGs in both developed and developing countries.

Other radiocommunication systems are also used to collect and transmit data related to weather conditions (humidity, rainfall rates etc.), for example IoT systems and radars. These sources of information form the critical mass needed to detect climate-related hazards.

Broadcasting and broadband services provide early warning to the population which reduces the impact of natural and environmental disasters by strengthening the resilience and increasing adaptive capacity.

Amateur radiocommunication services, among others, assist relief operations especially when other services are still not operational. More recently, HAPS have also been deployed to rapidly deliver services with minimal ground network infrastructure in disaster-relief missions.

WRC‑19’s decisions will affect services of utmost importance in these times of transformation and uncertainty. They will allow us to harness the power of ICTs to overcome the challenges and seize the opportunities of today’s digital economy.

Conclusions:

Radiocommunication services are deeply transforming the health, education, and transportation sectors. They are improving financial inclusion, increasing transparency and supporting accountable institutions, promoting sustainable agriculture, helping to preserve life in the air, at sea and on land. They are a crucial accelerator towards the achievement of all the SDGs in both developed and developing countries.

The four year preparation cycle leading to the WRC, the high-level of commitment of participants from governments and industry, done through arduous work and extensive international negotiations, both in the preparatory pro‑ cess and during the WRC‑19, will culminate in the signing of the WRC‑19 Final Acts and revising the Radio Regulations — the invaluable international treaty that is the foundation for rational, efficient and economical use of the radio-frequency spectrum, enabling radiocommunication technology developments since the start of radiocommunications, 113 years ago.

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

Backgrounder:

WRCs review the way radio spectrum is organized around the world, bringing together governments to negotiate and agree on the relevant modifications to the RR and commit to them. The preparatory process of WRCs involves extensive studies and preparatory discussions among all stakeholders (equipment makers, network operators, industry forums and users of spectrum) at national, regional and worldwide levels. Many of these stakeholders also serve as members of national delegations at the conference itself. This multi-stakeholder approach enables the necessary consensus to be built to ensure that WRCs maintain a stable, predictable and universally applied regulatory environment which secures long-term investments for a multi-trillion dollar industry.

The four-week program of a WRC includes the review and update of the global technical, operational and regulatory provisions that govern the use of the radio-frequency spectrum for terrestrial and satellite applications. In conducting its activities, the conference attempts to cast a proper balance:

Verizon CEO Hans Vestberg: The 5G Revolution and Separate 5G Standards?

Verizon CEO Hans Vestberg has warned that a lack of trust among telcos could lead to separate standards being set for 5G networks.  The assumption here was that Huawei would implement one type of 5G standard with rest of the world implementing another.  That would be very bad Vestberg said, just as the CDMA and GSM specifications split the cellular industry during development of 3G standards.

“If there are going to be different 5G global standards, it will impact the whole telecom industry,” he said.  “Right now, 5G is defined as a standard and everybody has agreed to it… 6G is probably coming in 7 or 8 years from now,” Vestberg said.

Vestberg’s comments came at Yahoo Finance All Markets Summit in New York.  It was in a response to a question about whether U.S. security concerns about China’s telecommunications giant Huawei Technologies were justified, as that company has emerged as the leader in 5G technologies.  The Verizon CEO declined to comment on possible security issues regarding Huawei Technologies.

However, he said that if trust – among the various technologies’ developers, and the nations that would use them – is lost, the consequence might be that different 5G providers would devise different standards.

–>We view such a statement as remarkable, if not outrageous, since Verizon does not send a representative to attend ITU-R WP5D meetings where the ONLY 5G radio standard- IMT 2020- is being progressed. Not once during this Yahoo interview did Vestberg say “IMT 2020.”

You can watch the video of the Vestberg interview here.

“The 5G technology is ultimately one of the most important infrastructures for the 21st century,” said Vestberg. “If we go back to – some of you might remember – the CDMA and GSM age, that really was not good.”  “The tech development is moving fast, software improvements are quick.  We are going to see an extraordinary impact from 5G in the next couple of years.  Verizon plans to have 5G coverage in 14 NFL stadiums,” he added.

ITU-R WP5D Brazil Meeting: Complete IMT 2020 RIT/SRITs from 3GPP, China & Korea advance; Nufront submits new EUHT RIT

SOURCE: Meeting Report of ITU-R WP5D Working Group on Technology Aspects (17 July 2019)

IMT-2020 RIT/SRITs:

This past week’s 32nd meeting of ITU-R WP 5D in Brazil was a milestone for the IMT-2020 process described in Document IMT 2020/2(Rev.1): Step 3 – submission / reception of the RIT and SRIT proposals and acknowledgement of receipt.

Seven submissions of candidate IMT-2020 RIT/SRITs were received at this meeting.  Importantly, some were updates to their previous submissions.

  1. 3GPP – RIT
  2. 3GPP  -SRIT
  3. China (People’s Republic of)
  4. South Korea (Republic of)
  5. ETSI (TC DECT) and DECT Forum
  6. TSDSI (India)
  7. Nufront [1]

Note 1. At this week’s ITU-R WP5D meeting in Brazil, Nufront (Beijing) Technology Co. Ltd (Nufront) proposed ‘EUHTRIT as the candidate IMT-2020 radio interface technology. The Nufront new candidate RIT is in addition to the RIT/SRITs previously input by 3GPP, China, South Korea, TSDSI (India), ETSI/DECT Forum.

Nufront provided the characteristics template, link budget template, compliance template, and self-evaluation report of the EUHT RIT. The submission templates follow the ITU-R IMT-2020 submission format and guidelines as defined in Report ITU‑R M.2411.

–>Please refer to my Comment in the box below this article.  It provides background on motivation for Nufront’s EUHT RIT proposal and their (failed) attempt to get IEEE 802.11AX to be included as either a merged RIT or a SRITs.

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

After review of all the submissions (see Table 1. below) under the IMT-2020 process Step 3 (the cut off date for submissions of candidate IMT 2020 RIT/SRITs), the meeting determined that the submissions from 3GPP (SRIT and RIT), China and Korea are “complete” per section 5 of Report ITU-R M.2411.  Therefore, they fulfilled the requirements for submission in Step 3 of the IMT-2020 process.

The meeting is of the view that, the supplied self-evaluation and any amendments accepted during this meeting for the submissions of ETSI (TC DECT) and DECT Forum (the component RIT DECT-2020 NR), Nufront and TSDSI do not yet permit WP 5D to determine if a complete and satisfactory self-evaluation as required by the IMT-2020 process has been fully provided.

A way forward for these submissions has been agreed by the meeting (Doc. 5D/TEMP/778-only available to those who have a TIES account). The Proponents should provide the full details requested in the process and in the specifically defined way to WP 5D, considering the comments raised in this meeting, in order for WP 5D to proceed further in the process with the submissions.

A decision on the submission above shall be taken in 33rd meeting WP 5D in December 2019.
For convenience, these submitted proposals are also posted on the “Web page for IMT-2020 submission and evaluation process.”

Under the IMT-2020 submission and evaluation process, the ITU-R will now proceed with the detailed evaluation of the proposed candidate technologies until 34th meeting of WP 5D in February 2020.

Appendix II: 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;

–Ongoing development of specifications for IMT and subsequent enhancements.

Appendix III: Agreed overall deliverables/work plan of WP 5D and technical requirements in order to build consensus on a global level:

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

Subject:  Acknowledgement of IMT-2020 proposals, future plans and evaluation report requests

Evaluation Workshop:
WP 5D will hold a Workshop on “IMT-2020 Terrestrial Radio Interfaces Evaluation” from 10 to 11 December, 2019 during its 33rd meeting to provide an interactive discussion among IEGs, proponents and WP 5D delegates.

The workshop will be held at the same venue as the 33rd meeting of WP 5D. The program of the workshop and detailed information about the workshop registration can be found on the “Web page for IMT-2020 submission and evaluation process” (under “Workshop on IMT-2020 Terrestrial Radio Interfaces Evaluation”). Parties interested in the details of the workshop (program, registration deadline, etc.) are kindly requested to check the workshop website periodically before the 33rd WP 5D meeting.

Evaluation Group discussion area:
The Evaluation Group discussion area can be found on “Web page for IMT-2020 submission and evaluation process.”

This discussion area is to exchange views on the characteristics of the proposed radio interface(s) technologies submitted by proponents and to discuss evaluation related issues among IEGs and the proponents.

The discussion area is available on a subscription basis for ITU-R members, designated representatives of the proponents of candidate technology submissions and designated representatives of the IEGs. Focal points of both the proponents and IEGs are requested to provide details of the designated representatives. IEGs and proponents are encouraged to participate in the Evaluation Group discussion area, and share the experiences that might be helpful to progress the evaluation activities.

Request for evaluation reports:
Following the IMT-2020 process on “Submission/Reception of the RIT and SRIT proposals and acknowledgement of receipt” in accordance with Document IMT-2020/2(Rev.2), WP 5D started the evaluation process from its 31st meeting in October 2018, and will last until its 34th meeting in February 2020.

Therefore, WP 5D expects to receive the final evaluation reports from the Independent Evaluation Groups on those IMT-2020 candidate technology RIT(s)/SRIT(s) that have been evaluated by its 34th meeting. While WP 5D kindly requests the independent evaluation groups to provide an interim
evaluation report for its 33rd meeting in December 2019 in which the Workshop on IMT-2020 evaluation will also be held.  It is also suggested that the evaluation reports contain information including the use of Report ITU-R M.2412, the considered test environment(s), the evaluated RIT(s)/ SRIT(s), and the evaluation results as requested by the compliance templates, but not limited to those. It is also requested that the interim evaluation report includes as much detail about the evaluation as possible.

Revision to Document IMT-2020/2:
Revision 2 to Document IMT-2020/2 “Submission, evaluation process and consensus building for IMT-2020”, is now available on “IMT-2020 documents”. This revision contains an additional WP 5D meeting planned in November 2020 to complete the Recommendation for detailed specifications of radio interface technologies for the terrestrial components of IMT-2020.

Updates to the ITU-R web page for the IMT-2020 submission and evaluation process and IMT-2020 documents Any future changes to the submission and evaluation process will be announced in Addenda to this
Circular Letter. Other information, such as information on the Workshop on IMT-2020 Terrestrial Radio Interfaces Evaluation, and interim evaluation report(s) will be updated dynamically on the “Web page for IMT-2020 submission and evaluation process” and “IMT-2020 documents.”

Consequently, Members and Sector members interested in the IMT-2020 development process including evaluation activities are kindly requested to periodically check the website.
