Question: In an Evolved Universal Terrestrial Radio Access (E-UTRA) network, when a User Equipment (UE) needs to transfer MR DC dedicated information via a ULInformationTransferMRDC message, what action does the UE take with the ul-DCCH-MessageNR?
Option 1: The UE clears the ul-DCCH-MessageNR to prevent information overlap.
Option 2: The UE sets the ul-DCCH-MessageNR to include the MR DC dedicated information to be transferred.
Option 3: The UE splits the ul-DCCH-MessageNR into two parts for simultaneous transmission.
Option 4: The UE delays submitting the ULInformationTransferMRDC message until a predefined timer expires.
Explanation: When there's a need to transfer MR DC dedicated information, the UE is required to include this specific data within the ul-DCCH-MessageNR field of the ULInformationTransferMRDC message. This ensures that the dedicated information is properly conveyed during the uplink transmission process, aligning with efficient radio resource control (RRC) protocol specifications in E-UTRA networks.
