Question: In a UTRA FDD/E-UTRA FDD network, what marks the end of the cell re-selection delay (for Release 11 and later with HS-DSCH DRX operation)?
Option 1: The moment when the UE successfully sends an RRC CONNECTION REQUEST message on Cell 2 to perform a Tracking Area Update procedure.
Option 2: When the UE completes its first successful data transmission on Cell 2 after re-selection.
Option 3: The instant the UE receives the first system information block (SIB) from Cell 2.
Option 4: When the UE starts decoding the broadcast channel of Cell 2.
Explanation: The cell re-selection delay ends when the UE begins sending preambles on the PRACH for an RRC CONNECTION REQUEST, initiating a Tracking Area Update on the new cell (Cell 2), signifying the transition to utilizing Cell 2 for communication setup.
