Overview:
This standard defines a new virtualized controller, Licensed and Unlicensed Controller (LUC), that may be initiated at the primarily edge cloud or any other cloud to coordinate the different traffic load transmissions in multi-connectivity modes. This virtual LUC has a unique ID that will coordinate with the network components for service management. The standard defines how the LUC is instantiated and chained with other 5G core NFs. The standard also defines the enabling reporting mechanisms that shall be installed at the UE or the 5G NR unified MAC. The framework for this standard is presented in figure below.
