Question: In a conformance test for a User Equipment (UE) as per telecom standards, what is the primary purpose of sending alternating "0" and "1" Transmit Power Control (TPC) commands in the downlink when measuring mean output power?
Option 1: To ensure the UE adjusts its transmit power to a specific target level for accurate measurement.
Option 2: To test the UE's ability to handle rapid changes in uplink transmission power.
Option 3: To verify the UE's TPC command decoding capability under varying downlink conditions.
Option 4: To evaluate the impact of TPC commands on UE battery life during intense transmission periods.
Explanation: The primary purpose of sending alternating "0" and "1" TPC commands is to set a stable reference point for measuring the UE's mean output power accurately, ensuring the UE adjusts its transmit power to a specific target level under controlled conditions.
