Question: In an NR (New Radio) network, when a UE (User Equipment) transmits a ULInformationTransfer message, what triggers the inclusion of dedicatedInfoF1c in the message contents?
Option 1: Receipt of a NAS (Non-Access Stratum) PDU from upper layers
Option 2: Initiation of a new RRC (Radio Resource Control) connection
Option 3: Handover from another 5G cell with ongoing F1-C related activities
Option 4: Need to transfer F1-C related information for an IAB-MT (Integrated Access Backhaul - Mobile Terminal)
Explanation: The correct answer is Option 4 because dedicatedInfoF1c is included in the ULInformationTransfer message only when there is a specific need to transfer F1-C related information, explicitly tied to the context of an IAB-MT, highlighting tailored messaging for efficient communication in specialized network configurations like Integrated Access Backhaul.
