Opportunistic Power Detection and Antenna Tuner Measurement During Concurrency

摘要

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.

主权项

1. A method for measuring transmitter power of a radio access technology (RAT) operating on a mobile communication device, comprising:
identifying an upcoming time window for taking a radio-frequency (RF) output power measurement of the RAT with a power detector; determining whether the upcoming time window is suitable for taking an accurate RF output power measurement of the RAT; and configuring the power detector to take an RF output power measurement of the RAT during the upcoming time window in response to determining that the upcoming time window is suitable for taking an accurate RF output power measurement of the RAT.
