Question: What is the characteristic of the additive sinusoid waveform that constitutes carrier leakage in a User Equipment (UE) radio transmission?
Option 1: It has the same frequency as the modulated waveform carrier frequency and may lie at the center of the narrowband assigned for transmission.
Option 2: It has a different frequency than the modulated waveform carrier frequency and is always offset from the center of the narrowband assigned for transmission.
Option 3: It is a non-sinusoidal waveform that is only present during specific modulation schemes.
Option 4: It is a random noise signal that is added to the modulated waveform.
Explanation: According to the specifications, carrier leakage is an additive sinusoid waveform with the same frequency as the modulated waveform carrier frequency. This characteristic allows it to potentially lie at the center of the narrowband assigned for transmission in UE of UL Categories M1 and M2.
