Question: Which logical channel is used for transmitting the `ULInformationTransfer-NB` message from the User Equipment (UE) to the Evolved Universal Terrestrial Radio Access Network (E-UTRAN)?
Option 1: DTCH (Dedicated Traffic Channel)
Option 2: DCCH (Dedicated Control Channel)
Option 3: CCCH (Common Control Channel)
Option 4: BCCH (Broadcast Control Channel)
Explanation: The `ULInformationTransfer-NB` message is utilized for the uplink transfer of Non-Access Stratum (NAS) information, which pertains to control plane signaling. Given its purpose, this message would logically be transmitted over a dedicated control channel, ensuring reliable and prioritized delivery of critical control information between the UE and E-UTRAN. Thus, DCCH, being responsible for carrying dedicated control information, is the appropriate choice.
