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.

Abstract: Methods for enabling a mobile device to efficiently resolve coexistence issues in a DSDA configuration by utilizing a feed forward strategy to avoid hand-shaking between software-implemented operations and firmware. The mobile device may employ a dual subscription, dual active (or “DSDA”) configuration in which two or more subscriptions may be associated with concurrently active communications, such as voice or data calls. The mobile device may be configured to predict activity associated with the concurrently active subscriptions, such as determining operations likely to be performed in a future time period. Such predicted activity information, as well as predefined actions and priority information, may be provided to a library common to both subscriptions. Firmware of the subscriptions may use the common library to detect current conflicts, such as desense, as well as actions to perform to resolve coexistence issues, such as blanking operations.

Abstract: Various embodiments provide methods, devices, and non-transitory processor-readable storage media for mitigating local oscillator (LO) spur interference between radio access technologies (RATs) operating on a multi-active communication device. The various embodiments provide methods, devices, and non-transitory processor-readable storage media to determine residual frequency error for a multi-active communication device and generate LO spur handling tables that may enable the multi-active communication device to compensate for the residual frequency error. A multi-active communication device may mitigate LO spurs by applying mitigation techniques to one or more RATs according to the LO spur handling tables. A multi-active communication device may mitigate LO spurs by turning off a LOs for one or more RATs according to the LO spur handling tables.

Abstract: The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing pipelining of operation registration data and conflict checking to predict radio frequency co-existence interference between two subscriptions operating on the DSDA device. The DSDA device may predict when a subscription (the “aggressor”) de-senses the other subscription (the “victim”) as a result of the aggressor's scheduled operations, by analyzing the conflicting operation registration data prior to the scheduled operation execution time. The operation registration data is received and analyzed close in time to the scheduled execution of the operation to limit the possibility of changes in the operation schedule and registration data.
