Option 4 as a 5G SA Complement

With this Operator Position Statement paper NGMN is urging the development finalization of 5G architecture “Option 4” to support the full realisation of 5G.

NGMN concludes in this document that Option 4 supporting a 5G core and dual connectivity with NR acting as a master is required so that baseline 5G NR radio performance can be enhanced through the use of LTE on top. 5G Standalone users can then access both NR and LTE spectrum in the lower frequency bands supporting wider coverage when it is beneficial to do so.
