Question: In E-UTRA Base Station (BS) conformance testing for PUCCH, what is the defined probability of false detection of ACK when input is only noise?
Option 1: Probability of 0.05 or less
Option 2: Probability of 0.1 or less
Option 3: Probability of 0.01 or less
Option 4: Probability of 0.005 or less
Explanation: The correct answer is based on the specified performance requirement for PUCCH in E-UTRA BS conformance testing, where it's mandated that the probability of false detection of the ACK (erroneous detection when input is only noise) shall be 0.01 or less, ensuring a high reliability threshold for signal detection in the absence of actual signals, minimizing false positives.
