Question: Under what condition is the minimum controlled output power of a User Equipment (UE) achieved in a UTRA FDD system?
Option 1: When the inner loop power control indicates maximum transmit output power and the open loop power control indicates minimum transmit output power.
Option 2: When both the inner and outer loop power controls are disabled for testing purposes.
Option 3: When the UE is in idle mode to conserve battery life.
Option 4: When both the inner loop and open loop power control indicate a minimum transmit output power is required, with the power control setting at its minimum value.
Explanation: The minimum controlled output power of a UE is achieved when all power control mechanisms (both inner loop and open loop) agree on the minimum required transmit power, and the power control setting is at its lowest, ensuring efficient use of power while maintaining necessary signal strength for communication.
