Question: In an NG-RAN architecture, what entity decides whether to apply multicast reception for UEs in the RRC_INACTIVE state for a specific multicast session on a cell level?
Option 1: gNB-CU (gNodeB - Central Unit)
Option 2: UE (User Equipment)
Option 3: AMF (Access and Mobility Management Function)
Option 4: SMF (Session Management Function)
Explanation: In the context of NG-RAN architecture, the gNB-CU is responsible for controlling and managing radio resources. The decision to apply multicast reception for UEs in the RRC_INACTIVE state, which involves radio resource management on a cell level, logically falls under the purview of the gNB-CU. This highlights the gNB-CU's role in optimizing network resource utilization for multimedia services even when UEs are in an inactive state.
