Question: In 3GPP conformance testing for UE OTA antenna performance, what is the primary purpose of identifying the center of the useful transmitted bits during power measurement sampling?
Option 1: To synchronize sampling with modulation for accurate EIRP measurements
Option 2: To adjust the Laptop Ground Plane Phantom's position for optimal DUT placement
Option 3: To calculate the Total Radiated Power (TRP) using relevant equations
Option 4: To determine the noise floor of the measurement receiver
Explanation: Accurately identifying the timing reference is crucial for synchronizing power measurement samples with the modulation on the burst, ensuring EIRP measurements are taken at the correct moments for accurate assessments of the UE's antenna performance in terms of radiated power, vital for conformance to 3GPP standards in OTA testing.
