Question: For a UTRA FDD UE supporting UL OLTD and E-DCH, what is the frequency range relative to the UE centre carrier frequency to which the spectrum emission mask applies?
Option 1: Between 2.5 MHz and 12.5 MHz away from the UE centre carrier frequency
Option 2: Exactly at the UE centre carrier frequency
Option 3: Between 100 kHz and 500 kHz away from the UE centre carrier frequency
Option 4: Beyond 20 MHz away from the UE centre carrier frequency
Explanation: The correct answer is Option 1 because, for UTRA FDD UEs that support UL OLTD and E-DCH, the spectrum emission mask applies to frequencies between 2.5 MHz and 12.5 MHz away from the UE's centre carrier frequency, crucial for managing out-of-channel emissions and minimizing interference with other frequency bands.
