Question: For a UE (User Equipment) supporting HSDPA (High-Speed Downlink Packet Access) and E-DCH (Enhanced Dedicated Channel), what is the basis for defining the maximum output power when transmitting with HS-DPCCH (High-Speed Dedicated Physical Control Channel) and E-DCH?
Option 1: According to the UE Maximum Power Reduction (MPR) for the nominal maximum output power.
Option 2: Based on the minimum transmission power required for a successful DPCCH (Dedicated Physical Control Channel) timeslot.
Option 3: Derived from the average power transmitted during a full DPCCH frame.
Option 4: Calculated from the peak power of a single E-DCH transmission burst.
Explanation: The correct answer is based on how the maximum output power for transmissions involving HS-DPCCH and E-DCH is defined in relation to the UE's capabilities. The UE Maximum Power Reduction (MPR) serves as a reference point for determining this maximum output power, ensuring that the device does not exceed its nominal maximum output power while transmitting with these channels. This approach helps maintain the balance between transmission power and potential interference in the network.
