Question: In a Base Station (BS) conformance testing scenario for FDD, what is the maximum allowed probability of ACK false alarm (P(DTX->ACK)) in multipath fading conditions?
Option 1: 10^(-1)
Option 2: 5 × 10^(-3)
Option 3: 10^(-2) or less
Option 4: 2 × 10^(-4)
Explanation: The correct answer, 10^(-2) or less, reflects the specified performance requirement for ACK false alarm in multipath fading conditions. This threshold ensures that the error ratio remains within acceptable limits when the receiver input signal is at a specified Ec/N0 limit, thus maintaining reliable communication link quality in telecom networks.
