Question: What is the required difference between CRS EPRE and MBSFN RS EPRE for a subcarrier spacing of 15kHz to ensure optimal UE demodulation performance?
Option 1: -3 dB
Option 2: 0 dB
Option 3: 5 dB
Option 4: 10 dB
Explanation: According to the specifications, for a subcarrier spacing of 15kHz, the difference between CRS EPRE and MBSFN RS EPRE should be set to 0 dB to ensure optimal UE demodulation performance. This is because different power offsets might affect the UE's ability to accurately demodulate the signal if this condition is not met.
