Question: For a UE (User Equipment) supporting both 7.68Mcps UTRA TDD and GSM, what type of measurement reporting is indicated by the network for a GSM cell in the described scenario?
Option 1: Event-triggered reporting of UTRA TDD RSCP (Received Signal Code Power)
Option 2: Periodic reporting of UTRA TDD RSRP (Reference Signal Received Power)
Option 3: Aperiodic reporting of GSM carrier RSSI (Received Signal Strength Indication) measurement
Option 4: Periodic reporting of the GSM carrier RSSI measurement
Explanation: In this scenario, the network specifically indicates to the UE that it should perform periodic reporting for the RSSI (Received Signal Strength Indication) of a GSM carrier. This is distinct from event-triggered or aperiodic reporting methods and also specific to GSM cells in a multi-mode operation context, highlighting how UEs manage mixed radio access technologies under directed measurement control.
