Question: Which logical channel is used for transmitting the RRCConnectionReestablishmentRequest message from the User Equipment (UE) to the Evolved Universal Terrestrial Radio Access Network (E-UTRAN)?
Option 1: Dedicated Control Channel (DCCH)
Option 2: Common Control Channel (CCCH)
Option 3: Dedicated Traffic Channel (DTCH)
Option 4: Broadcast Control Channel (BCCH)
Explanation: The RRCConnectionReestablishmentRequest message is used for reestablishing an RRC connection, which is a control plane function. In the context of E-UTRAN, the Common Control Channel (CCCH) is the logical channel designated for such control plane messages between the UE and the network when the UE does not have a dedicated connection established, making it the appropriate choice for transmitting the RRCConnectionReestablishmentRequest message.
