Question: During Initial BSIC identification, if a UE successfully decodes the BSIC of a GSM BCCH carrier, what is its next step regarding BSIC identification for other carriers?
Option 1: It will restart the BSIC decoding process from the strongest BCCH carrier with unknown BSIC after a brief pause.
Option 2: It will immediately proceed to attempt BSIC decoding on the next strongest BCCH carrier in signal strength order that still has an unknown BSIC.
Option 3: It will move the successfully identified GSM cell to the BSIC re-confirmation procedure and then abort all further BSIC decoding attempts for other carriers.
Option 4: It will wait for Tidentify abort (5000 ms) before attempting to decode the next BCCH carrier in signal strength order with unknown BSIC.
Explanation: Once a UE successfully decodes the BSIC of a GSM BCCH carrier, it immediately continues with the next BCCH carrier in signal strength order that has an unknown BSIC, ensuring efficient use of resources by prioritizing carriers based on signal strength and BSIC status.
