Progress Report on development of 5G standardisation
The 3GPP standards body has forced key decisions to be made in its RAN work some three months earlier than originally planned, concerning areas where system-level features have dependency on RAN decisions.
It has also agreed to develop Non-Standalone New Radio scenarios (that will use current LTE core network connectivity) in parallel with a Standalone scenario that will use the Next Generation Core.
A deliberate decision has been taken to defer decisions on use cases and scenarios until next year.
