Question: Which logical channel is used to transmit the PURConfigurationRequest-NB message from the UE to the E-UTRAN?
Option 1: CCCH (Common Control Channel)
Option 2: DCCH (Dedicated Control Channel)
Option 3: DTCH (Dedicated Traffic Channel)
Option 4: BCCH (Broadcast Control Channel)
Explanation: The PURConfigurationRequest-NB message, used for transferring PUR related information from the UE to the E-UTRAN, utilizes signaling radio bearers and RLC-SAP AM. Such control plane messages are typically mapped to the Dedicated Control Channel (DCCH), responsible for transmitting dedicated control information between the UE and the network, aligning with standard E-UTRAN architecture practices for handling signaling messages related to radio resource configuration and control.
