Question: In a reverberation chamber method for testing UE/MS Over The Air (OTA) antenna performance, what is the primary goal when adjusting the base station output power during BER measurement?
Option 1: To maximize the base station's output power for optimal coverage
Option 2: To achieve a Signal-to-Noise Ratio (SNR) of at least 20 dB
Option 3: To maintain a constant UE transmit power
Option 4: To find the lowest output power that yields a Bit Error Rate (BER) value of 1% or 0.2% using 40,000 or more bits
Explanation: The correct answer is focused on finding the minimum base station output power required to achieve a specific BER threshold, which is crucial for assessing the sensitivity and performance of the UE's antenna in a controlled, isotropic environment. This approach ensures that the UE can reliably receive signals at the lowest possible transmission power, reflecting its sensitivity level. The other options do not accurately represent the primary goal during this specific test procedure.
