ITU’s role and functions
• ITU is the UN Specialized Agency for information and
telecommunications technologies
• ITU allocates the global radio spectrum and satellite orbit 193 Member States
resources, develop the technical standards that ensure networks 567 Sector Members
and technologies seamlessly interconnect, and strive to improve 159 Associates
access to ICTs to underserved communities worldwide 150 Academia
• ITU membership counts 193 Member Countries, includes
regulators, leading academic institutions, standardization bodies
and more than 700 entities from the private sector

IMT-2000, IMT-Advanced, IMT-2020
• ITU-R has a rich history in the development of radio interface standards for
mobile communications under the name of International Mobile
Telecommunications (IMT) which are currently implemented around the world
• All 3G and 4G mobile broadband systems are based on the ITU’s IMT
standards.
• ITU established the detailed specifications for IMT-2000 and the first 3G
deployments commenced around the year 2000.
• In January 2012, ITU defined the next big leap forward with 4G wireless
cellular technology – IMT-Advanced – which is being progressively deployed
worldwide.
• The key elements of IMT-2020 are now defined, using the highly successful
partnership ITU-R has with the mobile broadband industry and the wide range
of stakeholders in the 5G community.

IMT Vision
• Globally harmonized standards enable global roaming and provide massive
economies of scale – resulting in lower cost services and equipment usable
everywhere
• The scope of IMT-2020 is then much broader than previous generations of mobile
broadband communication systems
• Three main usage scenarios for IMT-2020 have been identified in
Recommendation ITU-R M.2083, “IMT Vision – Framework and overall objectives
of the future development of IMT for 2020 and beyond”, these are enhanced
mobile broadband (eMBB), ultra-reliable and low latency communications (uRLLC),
and massive machine-type communications (mMTC)

General Evaluation Guidelines
• Self evaluation
– Must be a complete evaluation
• Principles
– The evaluation shall be
performed based on the
submitted technology proposals • External evaluation group
– Proposals’ evaluation shall – May perform complete or partial
follow this report on: evaluation
• Evaluation guidelines – May evaluate one or several
• Evaluation methodology technology proposals
• Evaluation configurations – Evaluations covering several
technology proposals are
encouraged

Global Core Specification and IPR policy
•
• GCS IPR policy
- Proponents and IPR holders should
– The set of specifications indicate their compliance with the ITU
that defines a RIT or an SRIT policy on intellectual property rights, as
specified in the Common Patent Policy
– Provided by a RIT/SRIT for ITU-T/ITU-R/ISO/IEC

groups/rsg5/rwp5d/imt-2020/Pages/ws-20171004.aspx)IMT-2020 early trials of candidate technologies
• There will now be a number of early technical trials, market trials
and deployments of 5G technologies based on the foreseen
developments for IMT-2020
• These technologies may not provide the full set of capabilities
envisaged for IMT-2020, but the results of these early activities will
flow forward into and assist the development of the final complete
detailed specifications for IMT-2020
• The scope of IMT-2020 is much broader than previous generations
of mobile broadband communication systems
11Conclusion
• Developed in collaboration with the ITU Membership (Member
States, SDOs, mobile industry, Academia, etc…) using a consensus
driven process

Decisions
• Outcome of the evaluation and assessment -> October 2019
• Detailed specification of IMT-2020 technology -> Year 2020
• Beyond year 2020, ITU will continue to assist the development and
the enhancement of IMT globally.
