Question: When calculating UE Relative Code Domain Power (CDP) accuracy for a UE using 16QAM modulation on uplink code channels, what adjustment is made to the Measured CDP ratio?
Option 1: A correction factor is applied directly to the Measured CDP ratio based on the modulation scheme used.
Option 2: The IQ origin offset power is removed from the Measured CDP ratio, and this removed power must also meet applicable requirements.
Option 3: The Nominal CDP ratio is adjusted by a fixed value to account for the 16QAM modulation efficiency.
Option 4: No adjustments are made to the Measured CDP ratio when 16QAM modulation is used on any uplink code channels.
Explanation: When a UE employs 16QAM modulation on its uplink code channels, the calculation for UE Relative Code Domain Power accuracy requires removing the IQ origin offset power from the Measured CDP ratio. This removed relative IQ origin offset power must also satisfy applicable requirements, ensuring both the adjusted measurement and leakage power comply with standards to accurately assess the UE's ability to set individual code powers relative to total active code power when using 16QAM modulation.
