Question: For a UTRA FDD UE supporting UL CLTD HSDPA and E-DCH (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 specifications for UTRA FDD UEs (particularly those supporting UL CLTD HSDPA and E-DCH in Release 11 and onwards), the defined 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 relative to the UE's carrier power.
