Abstract: Various aspects of the present disclosure are directed to apparatuses and methods that can mitigate the undesirable effects of residual side band (RSB) signal by actively re-tuning the local oscillator of a transmitter to be at or near the center frequency of the carrier. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various embodiments leverage the typical manner in which a RAT selects a supported frequency band listed in its acquisition database and the standard communications with its network indicating the supported frequency bands to avoid potential coexistence events with one or more other RATs. In particular, various embodiments include methods for avoiding band interference between RATs operating on a multi-SIM communication device by identifying the frequency bands available to each of the RATs, comparing the identified frequency bands to determine whether any RAT's frequency bands will interfere with one or more other RAT's frequency bands, and in response to determining that there is a possibility of frequency band interference, removing those interfering frequency bands from that RAT's acquisition database. As a result, during standard communications, that RAT will report to its network that it supports only non-interfering frequency bands.

Abstract: Methods implemented in a mobile communication device (e.g., a dual-SIM-dual-active or multi-SIM-multi-active communication device) for improving accuracy of radio-frequency (RF) output power measurements include opportunistically scheduling when a power detector takes RF output power measurements of a radio access technology (“RAT”). In various embodiments, a processor of the mobile communication device may ensure that the power detector takes an accurate RF output power measurement of the RAT by identifying an upcoming time window during which the RAT's transmit power is not artificially reduced as a result of performing transmit blanking/zeroing or artificially increased by transmissions originating from one or more other RATs operating on the device, and configuring or scheduling the power detector to take RF output power measurements of the RAT during that upcoming time window. A priority of the measured RAT may be increased in response to repeated delays in obtaining an RF output power measurement.
