Question: In a 3GPP-compliant TDD test scenario for Terminal conformance, if the minimum Test Time is less than the time required to reach the target number of error events, how is an early pass decision made for Bit Error Rate (BER)?
Option 1: If BER0 (excluding artificial error) is exactly equal to the early fail limit.
Option 2: If BER1 (including artificial error at the beginning of the test) is below the early pass limit.
Option 3: If the number of errors (ne) equals the number of bits (ns) transmitted in a TTI.
Option 4: If BER0 (excluding artificial error) is below the early pass limit.
Explanation: According to specifications, an early pass decision for Bit Error Rate (BER) is made when BER1 (including artificial error at the beginning of the test) is below the defined early pass limit, ensuring a required confidence level is achieved before the minimum test time has elapsed.
