Question: For a UE to undergo the test as per 3GPP specifications, what is a prerequisite regarding its receiver antenna connectors, and how should fading signals be applied to them?
Option 1: At least one receiver antenna connector with correlated fading of the signals.
Option 2: Exactly two receiver antenna connectors with correlated AWGN signals applied.
Option 3: A minimum of two receiver antenna connectors but without any specification on signal correlation.
Option 4: At least two receiver antenna connectors where fading of the signals and AWGN signals are uncorrelated.
Explanation: This is correct because the test's applicability, as specified, requires UEs to have at least two receiver antenna connectors. Moreover, for accurate testing, it's crucial that the fading of the signals and the addition of Additive White Gaussian Noise (AWGN) to each connector are uncorrelated, ensuring that the test measures the UE's performance under diverse, independent signal conditions, reflecting real-world scenarios more accurately. This setup helps in reliably determining the receive characteristic through the RLC SDU Error Rate (SDU ER) for various data rates, especially pertinent for Multimedia Broadcast Multicast Service (MBMS) capabilities.
