Question: In calculating Total Radiated Sensitivity (TRS) for a User Equipment (UE)/Mobile Station (MS), what is the primary basis for determining the effective isotropic sensitivity (EIS) in an anechoic environment with controlled field combinations?
Option 1: Average of the highest power levels received across all discrete field combinations that meet the target Bit Error Rate (BER) or Block Error Rate (BLER).
Option 2: Lowest power received by the UE/MS for a single discrete field combination that achieves the specified target BER/BLER level.
Option 3: Average of the lowest power levels received across multiple discrete field combinations in a Rayleigh fading environment, calibrated against a reference power transfer function.
Option 4: Maximum power transfer function calculated from the reflection coefficient and path loss for a fixed measurement antenna.
Explanation: The correct approach for calculating TRS involves averaging the lowest power levels received across multiple discrete field combinations that achieve the target BER/BLER, then calibrating this against a reference power transfer function to obtain an absolute TRS value, ensuring accuracy by accounting for various signal reception scenarios and environmental factors.
