Question: In 3GPP conformance testing for UE Receiver Performance, what is the primary distinction between measuring receiver sensitivity and transmitter performance in an anechoic or reverberation chamber?
Option 1: The type of chamber used (anechoic vs. reverberation) dictates different parameters of interest.
Option 2: The absolute sensitivity value at a predefined Bit Error Rate (BER) level is the key parameter for receiver performance.
Option 3: Receiver measurements require testing one antenna port at a time, unlike transmitter tests.
Option 4: The frequency bands used for receiver and transmitter performance measurements differ.
Explanation: When measuring UE receiver performance in accordance with 3GPP standards, the focus is on determining the absolute sensitivity value of the receiver at a specific Bit Error Rate (BER) level. This contrasts with transmitter performance measurements, which may focus on different parameters such as transmitted power or signal quality.
