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.
