3GPP 5G – Briefing for Evaluation Groups
October 27, 2018
This week’s 3GPP Workshop on 5G NR, hosted by the European Commission, has been a comprehensive briefing from the key experts in 3GPP for the benefit of the official Independent Evaluation Groups (IEGs), who’s job it will be to report to the International Telecommunications Union (ITU) on whether the 3GPP system for 5G meets the performance requirements (in ITU-R M.2412) for an IMT-2020 technology.
IMT stands for International Mobile Telecommunications, the term is used by the ITU to describe generations of radio interface standards for mobile systems. The latest member of the IMT family is IMT-2020 which calls for support for enhanced mobile broadband (eMBB) and for new ‘use cases’ that require massive machine-type communications (mMTC) and ultra-reliable and low latency communications (URLLC).
These objectives reflect perfectly 5G research project’s pre-standards work and also the priorities for 3GPP work from Release 15 onwards. It is a little bit of ‘chicken and egg’ in terms of which came first, but the alignment between IMT-2020, 5G R&D and the 3GPP work plan is an important achievement, which will help greatly at the World Radiocommunication Conference 2019, where deliberations on additional spectrum in support of IMT will take place.
In closing the 3GPP Workshop, Balazs Bertenyi concluded that - based on the results presented - there is a high level of confidence in the community that 3GPP’s submission to IMT-2020 will meet the ITU requirements. He asked all of the Independent Evaluation Groups to contact the 3GPP leadership and experts directly at any time in the process, to build on the dialogue started in Brussels this week.
The presentations below are provided for your information. They include the latest versions of the IMT-2020 submission templates and the latest 3GPP self evaluation results:
