Handbook on Global Trends in International Mobile Telecommunication

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,

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],

recommends

1 that the terrestrial radio interfaces for IMT-2020 should be:

– “[name of candidate radio interface technology AAA in this Recommendation]”¹;

– “[name of candidate radio interface technology BBB in this Recommendation]”²; and …………

– “[name of candidate radio interface technology ZZZ in this Recommendation]”ⁿ;

2 that the information provided or referenced in Annexes 1, 2, ･･･ and n should be used according to the terrestrial radio interfaces referred to in recommends 1 above as the complete set of standards for the detailed specifications of the terrestrial radio interfaces of IMT‑2020.
