  The International Telecommunication Union (ITU) is currently deliberating on
the finalization of candidate radio interface technologies (RITs) for IMT-2020
(International Mobile Telecommunications) suitability. The candidate
technologies are currently being evaluated and after a couple of
ITU-Radiocommunication sector (ITU-R) working party (WP) meetings, they will
become official. Although, products based on the candidate technology from 3GPP
(5G new radio (NR)) is already commercial in several operator networks, the ITU
is yet to officially declare it as IMT-2020 qualified. Along with evaluation of
the 3GPP 5G NR specifications, our group has evaluated many other proponent
technologies. 3GPP entire specifications were examined and evaluated through
simulation using Matlab and using own developed simulator which is based on the
Go-language. The simulator can evaluate complete 5G NR performance using the
IMT-2020 evaluation framework. In this work, we are presenting latency
parameters which has shown some minor differences from the 3GPP report.
Especially, for time division duplexing (TDD) mode of operation, the
differences are observed. It might be possible that the differences are due to
assumptions made outside the scope of the evaluation. However, we considered
the worst case parameter. Although, the report is submitted to ITU but it is
also important for the research community to understand why the differences and
what were the assumptions in scenario for which differences are observed.
