Question: What happens to the Nominal Maximum Output Power of a UTRA TDD User Equipment (UE) when operating in multi-code transmission mode?
Option 1: The power remains unchanged, only the tolerance is adjusted.
Option 2: The power is increased to compensate for the peak to average ratio difference.
Option 3: The power reduction is based on a fixed value specified by the UE's Power Class.
Option 4: The nominal maximum output power is reduced by the difference of peak to average ratio between single and multi-code transmission.
Explanation: In multi-code operation, the UE's transmitter manages multiple codes simultaneously, affecting its peak to average power ratio. To maintain efficient transmission and prevent overload, the nominal maximum output power is adjusted downward by an amount equal to the difference in this ratio between single-code and multi-code transmissions, ensuring compliance with regulatory limits while optimizing performance.
