Abstract: Various embodiments enable a multi-SIM multi-active (MSMA) communication device to operate a power amplifier in a power saving envelope tracking mode when a first radio frequency (RF) resource is supporting data transmission to a communication network associated with a first SIM and a second RF resource is supporting a voice call in discontinuous transmission mode. A MSMA communication device processor may monitor the second RF resource supporting the voice call for silence periods, the power amplifier of the first RF resource may operate in a first power-saving mode during silence periods on the voice call, and the power amplifier of the first RF resource may operate in a second power-saving mode when the voice call on second RF resource is not in a period of silence. Periods of silence may be determined by monitoring a protocol stack of the second RF resource for silence descriptor (SID) frames scheduled for transmission.
