FG IMT-2020: Report on Standards Gap Analysis.
At its meeting in Geneva, 20 April - 1 May 2015, ITU-T Study Group 13 (SG13)
established the ITU-T Focus Group on IMT-2020 (FG IMT-2020) to identify the
standards gaps for the '5G' development of International Mobile
Telecommunications (IMT) for 2020 and beyond on the non-radio related network
parts. At the recent SG13 meeting, the Focus Group delivered the requested gap
analysis. It is based on the studies on several key technical topics related to
the non-radio aspects of IMT-2020. It identifies and describes 85 gaps in five
technical areas in the context of IMT-2020 networks: (1) High-level network
architecture; (2) Network softwarization; (3) End-to-end quality of service;
(4) Front haul / back haul; (5) Emerging networking technologies - ICN.

The complete analysis for your consideration is in Annex 1. Furthermore we
would like to inform you that SG13 has extended the lifetime of the focus group
until 31 December 2016 with the new Terms of Reference shown in Annex 2.
