Work has started in ITU and 3GPP to develop requirements and specifications for new radio (NR) systems, as in the Recommendation ITU-R M.2083
"Framework and overall objectives of the future development of IMT for 2020 and beyond", as well as 3GPP SA1 study item New Services and Markets Technology Enablers (SMARTER) and SA2 study item Architecture for NR System. 3GPP has to identify and develop the technology components needed for successfully standardizing the NR system timely satisfying both the urgent market needs, and the more long-term requirements set forth by the ITU-R IMT-2020 process.
The present document covers the Radio Access Architecture and Interface aspects of the study item "New Radio Access Technology". The purpose of this TR is to record the discussion and agreements that arise in the specification of the "New Radio Access Technology" from an Access Architecture and Interface specification point of view.
