Question: How does a UE in RRC_CONNECTED mode, supporting reception of CMAS indication in Control Channel Element (CCE), become aware of the presence of one or more CMAS notifications?
Option 1: Through a dedicated signaling message sent directly to the UE's unique identifier.
Option 2: Via control channels associated with the shared data channel.
Option 3: By periodically checking SystemInformationBlockType12 for new CMAS notifications.
Option 4: Upon receiving a Paging message intended for all UEs in the cell.
Explanation: According to the specified behavior for UEs in RRC_CONNECTED mode that support reception of CMAS indications, control channels associated with the shared data channel are utilized to inform the UE about the presence of one or more CMAS notifications. This approach leverages existing channel structures for efficient notification, differing from methods used for UEs in RRC_IDLE or those not in Cell Edge (CE) scenarios.
