Question: In A-GPS testing for UTRAN, as per 3GPP specifications, what is the characteristic of the offset value applied to the IE GPS TOW msec for Coarse Time Assistance in TTFF test cases?
Option 1: Uniform random distribution within a defined error range
Option 2: Fixed deviation from GPS system time to simulate real-world delays
Option 3: Normally distributed around the nominal GPS system time value
Option 4: Deterministic offset increasing linearly with each test instance
Explanation: According to the specifications, for every Test Instance in TTFF test cases involving Coarse Time Assistance, the IE GPS TOW msec is assigned a random offset relative to GPS system time. This offset follows a uniform random distribution within a defined error range, ensuring variability and comprehensive testing across possible scenarios. This approach helps in evaluating the performance of A-GPS under diverse conditions, reflecting real-world uncertainties.
