Question: For a FDD UE supporting UL CLTD and E-DCH, what is the basis for defining the maximum output power tolerance when transmitting with HS-DPCCH and E-DCH?
Option 1: According to the UE's Minimum Power Reduction (MPR) for the nominal minimum output power.
Option 2: Based on the UE's thermal design for optimal heat dissipation during transmission peaks.
Option 3: Defined according to the UE Maximum Power Reduction (MPR) for the nominal maximum output power.
Option 4: Determined by the network's signal strength requirements for the specific cell.
Explanation: The correct answer is based on understanding how maximum output power tolerances are defined in UL CLTD with HS-DPCCH and E-DCH. The UE Maximum Power Reduction (MPR) for the nominal maximum output power is the standard reference point, ensuring UEs operate within safe and efficient power limits while maintaining required signal quality, aligning with telecom principles of balancing transmission power with network and device capabilities.
