Question: For a UTRA FDD UE supporting UL OLTD and HSDPA (Release 11 and later), what is the frequency range relative to the UE centre carrier frequency to which the spectrum emission mask applies?
Option 1: Up to 1 MHz away from the UE centre carrier frequency
Option 2: Between 5 MHz and 20 MHz away from the UE centre carrier frequency
Option 3: Exactly at the UE centre carrier frequency
Option 4: Between 2.5 MHz and 12.5 MHz away from the UE centre carrier frequency
Explanation: This is correct because, according to the specifications for UTRA FDD UEs that support UL OLTD and HSDPA in Release 11 and later releases, the spectrum emission mask specifically applies to frequencies that are between 2.5 MHz and 12.5 MHz away from the UE's centre carrier frequency. This range is crucial for managing out-of-channel emissions relative to the UE's carrier power.
