Question: During GSM cell re-confirmation in a TDD system, what action does the UE take if it fails to decode the BCCH (Broadcast Control Channel) after two successive attempts for a specific GSM cell?
Option 1: The UE continues re-confirmation attempts for that cell until successful.
Option 2: The UE treats the GSM cell as new with unidentified timing and initiates the initial identification procedure.
Option 3: The UE skips this cell and only attempts re-confirmation for the next 5 strongest cells in the list.
Option 4: The UE temporarily suspends all re-confirmation attempts for all GSM cells.
Explanation: This is because, according to the specified behavior for TDD systems during GSM cell re-confirmation, if the UE fails to decode the BCCH after two successive attempts for a specific GSM cell, it should abort re-confirmation attempts for that cell and treat it as a new cell. This involves moving the cell to the initial identification procedure to gather timing information again, ensuring the UE maintains accurate data on the cells in its monitored list.
