Question: For a UE (User Equipment) supporting UL OLTD, HSDPA, and E-DCH in FDD mode, 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 for the nominal minimum output power.
Option 2: Based on the UE's Maximum Power Reduction (MPR) for the nominal maximum output power.
Option 3: Derived from the average power transmitted during a DPCCH timeslot without MPR consideration.
Option 4: Calculated using the sum of individual powers for HS-DPCCH and E-DCH transmissions without MPR application.
Explanation: The correct answer is based on understanding that Maximum Power Reduction (MPR) adjusts UE's transmit power to mitigate issues like out-of-band emissions. For UEs supporting UL OLTD with HS-DPCCH and E-DCH in FDD mode, defining maximum output power tolerance via MPR ensures regulatory compliance while maintaining optimal performance, reflecting nuanced understanding of telecom network power management for high-speed data services.
