Question: In an FeMBMS/Unicast-mixed cell, how are UEs that do not support FeMBMS handled to prevent them from accessing the cell?
Option 1: Cell barring mechanism via SIB1 is used to prevent camping of non-FeMBMS capable UEs.
Option 2: System Information Block (SIB) 2 is modified to exclude non-FeMBMS UEs.
Option 3: A dedicated FeMBMS support indicator in the UE's capability report is checked before allowing access.
Option 4: ETWS/CMAS notifications are used to inform non-FeMBMS UEs to select another cell.
Explanation: To maintain efficient operation, the network employs a cell barring mechanism through System Information Block 1 (SIB1) to prevent UEs not supporting FeMBMS from camping on these cells, ensuring only compatible devices utilize the cell's resources.
