Question: For a UE (User Equipment) undergoing the MCCH (Multicarrier Control Channel) receive characteristic test based on SDU error rate (_SDU_ER), what is a prerequisite for the UE's antenna configuration?
Option 1: The UE must have at least one receiver antenna connector with correlated fading signals.
Option 2: The UE can have any number of receiver antenna connectors without specific fading signal requirements.
Option 3: The UE must have at least two receiver antenna connectors where the fading of the signals and AWGN (Additive White Gaussian Noise) signals applied are uncorrelated.
Option 4: The UE requires a single receiver antenna connector with uncorrelated fading and AWGN signals.
Explanation: This is because the correct functioning of the MCCH receive characteristic test, as determined by the SDU error rate (_SDU_ER), relies on the UE having multiple (at least two) receiver antenna connectors. Moreover, to accurately assess the UE's performance under diverse signal conditions, it's crucial that the fading and AWGN signals applied to each of these connectors are uncorrelated, ensuring a comprehensive test of the UE's capabilities across various states.
