Question: For a UTRA FDD UE supporting HSDPA and Dual Cell E-DCH, when is the minimum controlled output power achieved?
Option 1: When the power control setting is at its maximum value, combining both inner loop and open loop power control indications.
Option 2: When the power control setting is set to a minimum value, with both inner loop and open loop power control indicating a minimum transmit output power is required.
Option 3: During handover procedures from one base station to another, regardless of the current power control settings.
Option 4: Only when the UE operates in idle mode, to minimize overall power consumption.
Explanation: This is correct because the minimum controlled output power of the UE occurs when the power control setting is at its lowest point, and both inner loop and open loop power control mechanisms concur that the minimum possible transmit power should be used, ensuring efficient power management without compromising connectivity.
