Abstract: Methods and systems for managing temperature of 5G UE by TX/RX path switching. If temperature of the UE increases beyond a preconfigured threshold due to heat contributed by a first TX/RX path of the UE, embodiments perform switching from the first TX/RX path to a second TX/RX path to control the temperature of the UE.

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.

Abstract: Methods and devices are disclosed for enabling improved performance for page decodes on a SIM of a multi-SIM wireless communication device in which a shared radio frequency (RF) resource is used to read system information for a different SIM. After determining that a first SIM is using the shared RF resource to decode SIBs, the wireless device may receive information about an upcoming page decode time for monitoring a paging channel associated with the second SIM.

Control of the RF resource may be released from the modem stack associated within the first SIM, and gained by a modem stack associated with the second SIM during the RF resource release gap.

Abstract: Various embodiments in the disclosure provide methods implemented by a processor executing on a mobile communication device to dynamically determining whether the power saved by powering down the RF chain between the end of the last reception activities and the beginning of the next reception activities will exceed the power expended to reinitialize the RF chain's components and registers for the next reception activities. Based on this determination, the device processor may configure the RF chain either to power down fully, as in conventional implementations, or to enter a low-power mode in which power is maintained to the power rails supplying the memory registers storing RF communication data, thereby avoiding the power surge of restarting the registers and part of the power drain associated with writing the communication data back into the registers. In some embodiments, the mobile communication device may be a multi-SIM device.
