Question: Upon initiating an ULInformationTransferIRAT message in a 5G network, what action does the User Equipment (UE) take when there is dedicated NR (New Radio) information to be transferred?
Option 1: The UE discards any existing ul-DCCH-MessageNR and proceeds with submitting an empty ULInformationTransferIRAT message for transmission.
Option 2: The UE sets the ul-DCCH-MessageLTE instead, incorporating the dedicated NR information for transfer within the LTE (Long-Term Evolution) framework.
Option 3: The UE sets the ul-DCCH-MessageNR to include the IRAT dedicated NR information and then submits the ULInformationTransferIRAT message to lower layers for transmission.
Option 4: The UE delays submission of the ULInformationTransferIRAT message, pending additional context from the network before incorporating dedicated NR information.
Explanation: This is the correct procedure. When there's a need to transfer dedicated NR information, the UE sets the ul-DCCH-MessageNR with the IRAT dedicated information and then submits the ULInformationTransferIRAT message to lower layers for transmission, ensuring seamless integration of NR capabilities within the existing RRC framework.
