Question: In a reverberation chamber method for testing UE antenna performance, what is the primary goal when adjusting the base station output power during BER measurement?
Option 1: To maximize the UE's transmission power
Option 2: To achieve a Signal-to-Noise Ratio (SNR) of at least 10dB
Option 3: To find the lowest output power yielding a Bit Error Rate (BER) of 0.2% using 40,000 or more bits
Option 4: To maintain a constant UE receive signal power across all test scenarios
Explanation: The correct answer is focused on the specific objective mentioned in the test procedure - to identify the minimum base station output power required to achieve a targeted low BER (0.2%) with a substantial number of bits (40,000 or more), ensuring accurate assessment of UE's sensitivity and antenna performance under controlled conditions.
