Question: In a 3GPP-compliant FDD UE supporting UL OLTD and HSDPA, when calculating the Nominal CDP ratio for 16QAM modulation, what adjustment is made to the βed value?
Option 1: A fixed correction factor of 0.5 dB is added to the βed value.
Option 2: The βed value is multiplied by a factor derived from the symbol fractions (00, 01, 10, 11) as per a predefined formula.
Option 3: No adjustment is made; the nominal CDP ratio calculation remains unchanged for all modulation types.
Option 4: The βed value is divided by the sum of all nominal CDPs, which equals 1 by definition, and then a square root of the sum of squared fractions of symbols is applied.
Explanation: For 16QAM modulation in FDD UEs supporting UL OLTD and HSDPA, the Nominal CDP calculation involves adjusting the βed value using a formula that incorporates symbol fractions (for symbols 00, 01, 10, 11), ensuring accuracy in UE Relative CDP measurements by squaring, summing with specific coefficients, and taking the square root.
