Abstract

A method of wireless communication includes partitioning coexistence tasks between short term policy setting tasks and policy implementing tasks, processing the short term policy setting tasks using a first set of computing resources, and processing the policy implementing tasks using a second set of computing resources. The first set may be software resources configured for slower execution of tasks and the second set may be hardware resources configured for just-in-time execution of tasks. The policy may determine a time after which a first radio event is not to be interrupted and granting or denying later events based on whether they would begin before or after the do-not-interrupt time. The do-not-interrupt time may be based on a weighted priority of the first radio event.
