10 NSA Non-Standalone Non Standalone proposes several options for Coexistence: 3/3a/3x where 4G CN is being used 7/7a/7x which uses 5G CN 10

11 5G Dual Connectivity 11

12 Next Generation Core Option 3x Control Plane: The involved core network entity is the MME. S1-MME is terminated in MeNB and the MeNB and the SgNB are interconnected via X2-C User Plane: X2-U interface is the user plane interface between MeNB and SgNB, and S1-U is the user plane interface between MeNB and S-GW 12
