Question: In a PRACH preamble transmission quality test, what is the primary reason for selecting only a subset (10 out of 384) of possible access slot and signature configurations for testing?
Option 1: To ensure comprehensive coverage of all possible interference scenarios.
Option 2: To align with the typical number of concurrent users in a cell.
Option 3: To focus on configurations most commonly used by UEs (User Equipment) near cell boundaries.
Option 4: To minimize test time while still validating key transmission quality parameters.
Explanation: The correct answer highlights the practical consideration of reducing overall test duration without compromising validation of critical transmission quality aspects, balancing thoroughness with efficiency.
