IMT-2020 standardization process

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

ITU-R Working Party 5D is well on schedule to produce technical specifications for 5G in early 2020.

Most of the innovation to deliver 5G

needs to happen in the fixed network

How to design (network architectures, interfaces, protocols, algorithms, data

format)

to make best use of ML?

ITU-T Standards to support non-radio aspects of 5G

• Softwarization: Designing, implementing,

deploying, managing and maintaining

networks using software

• Slicing, e.g. separate slices for

• voice communications

• automated driving

• wide range of other use cases

• Fixed Mobile Convergence: Network

architecture to support fixed / mobile

convergence, with seamless user

experience

Softwarization, Slicing, and FMC

• management: In the context of IMT-2020, the processes aiming at fulfilment, assurance, and billing of services, network functions, and resources in both physical and virtual infrastructure including compute, storage, and network resources.

• orchestration: In the context of IMT-2020, the processes aiming at the automated arrangement, coordination, instantiation and use of network functions and resources for both physical and virtual infrastructure by optimization criteria.

Cooperation among standards development

organizations

Exchange of information and collaboration among organisations is essential for

5G (given its large spectrum of technologies, services, stakeholders)

ITU-T SG13 “Joint Coordination Activity on IMT2020”

(JCA-IMT2020) • To promote high-level coordination in IMT2020 standardization

• A global IMT2020 standards roadmap (for non-radio aspects) will be

maintained via regular exchanges with relevant external entities. Open

to ITU Members and designated representatives of relevant Standards

Development Organizations and Forums

• There is a mailing list for discussion and information
