Question: For a UE (User Equipment) supporting HSDPA (High-Speed Downlink Packet Access) in FDD (Frequency Division Duplex) mode, what is the primary factor determining its maximum output power when transmitting with HS-DPCCH (High-Speed Dedicated Physical Control Channel)?
Option 1: The type of UTRA (Universal Terrestrial Radio Access) network it connects to.
Option 2: The Power Class of the UE.
Option 3: The release version of the HSDPA specification implemented.
Option 4: The duration of the DPCCH (Dedicated Physical Control Channel) timeslot.
Explanation: According to telecom standards for FDD UEs supporting HSDPA, the maximum output power with HS-DPCCH transmission is primarily defined by the UE's Power Class. This classification system standardizes the maximum transmit power levels for different device types, ensuring compliance with regulatory limits and minimizing interference while maintaining optimal network performance.
