Question: For a UE (User Equipment) supporting HSDPA and Dual Cell E-DCH in FDD mode, what is the applicable frequency range around the UE centre frequency for verifying the spectrum emission mask requirements, assuming maximum UE output power?
Option 1: Between 1 MHz and 10 MHz away from the UE centre frequency
Option 2: Between 5 MHz and 20 MHz away from the UE centre frequency
Option 3: Between 10 MHz and 30 MHz away from the UE centre frequency
Option 4: The entire frequency band of the assigned channel
Explanation: This is correct because, for UTRA FDD UEs supporting HSDPA and Dual Cell E-DCH, spectrum emission mask requirements are defined for frequencies between 5 MHz and 20 MHz away from the UE's centre frequency of the two assigned channel frequencies, under maximum UE output power, to ensure controlled emissions in adjacent bands and minimize potential interference.
