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.

The ITU Radiocommunication Assembly, considering

a) that IMT systems are mobile broadband systems including IMT-2000, IMT‑Advanced and IMT-2020;

b) that IMT-2020 systems include the new capabilities of IMT that go beyond those of IMT-2000 and IMT-Advanced, and will interwork with and complement existing IMT and its enhancements;

c) that IMT-2020 is envisaged to expand and support diverse usage scenarios and applications that will continue beyond the current IMT;

d) that such systems provide access to a wide range of telecommunication services including advanced mobile services, supported by mobile and fixed networks;

e) that ITU has contributed to standardization and harmonized use of IMT, which has provided telecommunication services on a global scale and global operation and economies of scale are key requirements for the success of mobile telecommunication systems;

f) that IMT-2020 systems support low to high mobility applications (NOTE: but NOT fixed wireless) and a wide range of data rates in accordance with user and service demands in multiple user environments;

g) that the usage scenarios of IMT-2020 include enhanced Mobile Broadband, ultra-reliable and low latency communication and massive machine-type communication;

h) that IMT-2020 systems support not only human communications but also the machine type communications;

i) that IMT-2020 systems support ultra-reliable and low latency communications which are necessary in particular use cases;

j) that IMT-2020 also has capabilities for high-quality multimedia applications within a wide range of services and platforms providing a significant improvement in performance, quality of service and user experience;

k) that the key features of IMT-2020 are:

– a high degree of commonality of functionality worldwide while retaining the flexibility to support a wide range of services and applications in a cost-efficient manner;

– compatibility of services within IMT and with fixed networks;

– capability of interworking with other radio access systems;

– high-quality mobile services for maximum user experiences;

– user equipment suitable for worldwide use;

– worldwide roaming capability;

– further enhanced peak data rates to support advanced services and applications (10 Gbit/s for uplink and 20 Gbit/s for downlink) and enables 100 Mbit/s user experienced data rate;

– enhanced spectrum efficiency by three times higher compare to IMT-Advanced;

– high downlink area traffic capacity;

– ultra low latency over-the air;

– extreme connection density;

– ultra reliability communication success probability within 1 ms in certain condition;

– high speed mobility station ;

– enhanced energy efficiency mechanism;

l) that these features enable IMT-2020 to address evolving user needs in various usage scenarios;

m) that the capabilities of IMT-2020 systems are being continuously enhanced in line with technology developments;

n) the necessity of priority services (e.g. emergency calls shall be supported as higher priority than other commercial services);

o) that IMT systems are considered as the major candidate for Public Protection and Disaster Relief (PPDR);

p) that due to the large effective bandwidths required to support the very high data rates needed for the various services offered, allowances must be made for either much larger single carrier bandwidths (even as spectral efficiencies increase) or aggregation of RF carriers;

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,

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

  1. At next week’s ITU-R WP5D meeting, the committee will decide if the IMT 2020 RIT/SRITs from ETSI/DECT Forum, TSDSI and Nufront will be progressed along with those already approved from 3GPP, China and Korea.

    It remains to be determined how 3GPP release 16 – with ultra high reliability, ultra low latency, 5G control plane/signaling, 5G network management, 5G packet core (5GC) – will be input to future ITU-R WP 5D meetings when that spec is completed in mid 2020.
    –>My guess is that 3GPP release 16 functionality related to IMT 2020 will likely be a joint contribution from 3GPP member companies at 5D Meeting No. 35 (24 June-1 July 2020, [China]).

  2. At it’s Dec 11-13, 2019 meeting in Geneva, ITU-R WP 5D SWG Evaluation/WG Technology Aspects has determined that 3GPP, China, Korea, TSDSI (India), ETSI/DECT Forum and Nufront IMT 2020 RIT self evaluations were complete as per IMT-2020 Process Step 3.

    That result progresses IMT 2020 RITs from TSDSI, ETSI-DECT Forum, Nufront (still some issued with this one) which were said to be incomplete at the previous WP 5D meeting (#32) as per this text:

    “Working Party 5D (WP 5D) has so far identified at WP 5D meeting #32, in its review of the Proponent (TSDSI/ETSI-DECT Forum/Nufront), some submission deficiencies and clarification of technology issues which impact the submission and the ability of WP 5D to have the submission move forward in the IMT-2020 process. The proponent had been requested in the discussions in WP 5D meeting #32 to remedy the deficient information.”

    “This submission cannot, in its current form, be determined to have satisfactorily fulfilled Section 4.3 for the self-evaluation. The supplied self-evaluation and any amendments accepted during WP 5D meeting #32 for TSDSI RIT 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.
    The Proponent should provide the full details requested in the process and in the specifically defined way to WP 5D, considering the comments raised in WP 5D meeting #32, in order for WP 5D to proceed further in the process with this submission”
    ………………………………………………………………
    Note that ATIS and 5GMF (Japan) stated that China and Korea IMT 2020 IMT 2020 RIT submissions are technically identical to 3GPPs which is based on 3GPP Release 15 (for both 5G-NR and NB-IoT).
