Question: In a reverberation chamber method for UE/MS OTA antenna performance testing, what is the primary purpose of sending continuously Up power control commands to the UE at the beginning of the procedure?
Option 1: To simulate real-world fading conditions and test the UE's adaptive transmission capabilities.
Option 2: To ensure the UE reaches its maximum transmission power before measuring Total Radiated Power (TRP).
Option 3: To synchronize the UE with the test system's sampling rate for accurate measurements.
Option 4: To verify the UE's compliance with noise floor regulations in various environments.
Explanation: The correct answer is Option 2 because sending Up power control commands continuously until the UE reaches maximum power ensures that all subsequent measurements (e.g., of TRP) are conducted at the UE's highest transmission power level, maximizing the accuracy and relevance of the antenna performance measurements in a controlled environment.
