Question: What action does a non-RedCap, non-eRedCap UE take if it is in RRC_IDLE or RRC_INACTIVE and unable to acquire SIB1 from a cell?
Option 1: Consider the cell as barred and perform cell re-selection to other cells on the same frequency.
Option 2: Attempt to acquire MIB before taking any further action.
Option 3: Automatically switch to RRC_CONNECTED mode to retry SIB1 acquisition.
Option 4: Treat the cell as a normal cell for re-selection purposes without considering it barred.
Explanation: According to specified behavior, if a non-RedCap, non-eRedCap UE in RRC_IDLE or RRC_INACTIVE cannot acquire essential system information (SIB1), it considers the cell barred. The UE then performs cell re-selection to other cells on the same frequency, following procedures for handling barred cells in idle or inactive states.
