Question: In a reverberation chamber method for UE 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 ensure the UE operates at its maximum transmission power for accurate Total Radiated Power (TRP) measurements.
Option 2: To simulate a real-world scenario where the UE experiences frequent handovers between cells.
Option 3: To test the UE's ability to adapt to changing network conditions without impacting antenna performance.
Option 4: To verify the UE's compliance with power saving features in low-traffic scenarios.
Explanation: The primary purpose of sending 'Up' power control commands is to ensure the UE reaches its maximum transmission power. This is crucial for accurate measurements of Total Radiated Power (TRP) in a controlled environment, providing a consistent and maximum power output from the UE, essential for evaluating antenna performance under optimal conditions.
