Question: Which of the following services provided by the Radio Resource Control (RRC) protocol to upper layers is specifically intended for a single User Equipment (UE)?
Option 1: Broadcast of common control information
Option 2: Notification of UEs in RRC_IDLE and RRC_INACTIVE about a terminating call
Option 3: Transfer of dedicated control information, i.e., information for one specific UE
Option 4: Broadcast of positioning assistance data to all cells in the network
Explanation: The correct answer is Option 3 because "Transfer of dedicated control information" explicitly refers to handling "information for one specific UE", distinguishing it from broadcast services which are meant for multiple or all UEs. This highlights the RRC's role in managing individual device communications within the broader network, ensuring personalized data exchange between the network and a single UE.
