Question: What information does a User Equipment (UE) include in the onDemandSIB-RequestList when requesting required System Information Blocks (SIBs)?
Option 1: requestedSIB-List and requestedPosSIB-List
Option 2: only requestedSIB-List
Option 3: only requestedPosSIB-List
Option 4: neither requestedSIB-List nor requestedPosSIB-List
Explanation: According to the Radio Resource Control (RRC) protocol specification, when a UE requests required SIB(s), it includes the requestedSIB-List in the onDemandSIB-RequestList. Similarly, when requesting required posSIB(s), it includes the requestedPosSIB-List in the onDemandSIB-RequestList. Therefore, the correct answer is that the UE includes both requestedSIB-List and requestedPosSIB-List in the onDemandSIB-RequestList.
