Question: In a split gNB architecture, what action can the gNB-DU take to stop receiving RAN visible QoE measurement results from the gNB-CU?
Option 1: Initiate QoE Information Transfer Control procedure towards the gNB-CU
Option 2: Send a Deactivation Request to the UE for QoE Measurements
Option 3: Modify the DRB ID(s) associated with the QoE Information
Option 4: Restart the gNB-CU to reset QoE Measurement Transfers
Explanation: In a split gNB architecture, the correct action for the gNB-DU to stop receiving RAN visible Quality of Experience (QoE) measurements involves initiating a procedure that directly communicates its preference to the gNB-CU. Initiating the QoE Information Transfer Control procedure is the standardized approach for the gNB-DU to manage (including deactivating) the transfer of RAN visible QoE measurement results from the gNB-CU.
