Question: In 3GPP TDD radio resource management, when testing a parameter with inherent statistical variations, what is primarily established to determine the reliability of the test outcome?
Option 1: Test Variable Value (TVV) Threshold
Option 2: Device Under Test (DUT) Classification Criteria
Option 3: Radio Resource Management (RRM) Algorithm Type
Option 4: Confidence Level for Statistical Accuracy
Explanation: When testing parameters with statistical variations in the context of 3GPP TDD radio resource management, a Confidence Level is crucial. It defines the probability that a Device Under Test (DUT) passing the test actually meets the specified requirement. This, in turn, influences the number of test repetitions and the pass/fail criteria, ensuring the reliability of the test outcome. This concept is particularly relevant for managing the inherent uncertainties in statistical testing, aligning with best practices for ensuring the accuracy and trustworthiness of test results in telecommunications.
