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.
