Question: In CELL_DCH state, for GSM measurements using measurement occasions and idle intervals, how are the remaining measurement opportunities (after allocating every second one for initial BSIC identification) scheduled by the UE?
Option 1: 2 out of 4 for GSM carrier RSSI measurements, 2 out of 4 for GSM BSIC reconfirmation
Option 2: All remaining opportunities are allocated for GSM carrier RSSI measurements
Option 3: 3 out of 4 for GSM carrier RSSI measurements, 1 out of 4 for GSM BSIC reconfirmation
Option 4: The UE alternates between GSM carrier RSSI and GSM BSIC reconfirmation for each remaining opportunity
Explanation: After allocating every second measurement opportunity for GSM initial BSIC identification, the UE schedules the remaining opportunities with a specific ratio: 3 out of 4 for measuring the RSSI of GSM carriers, and 1 out of 4 for reconfirming the GSM Base Station Identity Code (BSIC), ensuring a balance between monitoring signal strength and verifying cell identity.
