Abstract

A coexistence manager may manage potential resource conflicts between radios, in particular between a Long Term Evolution (LTE) radio and between a Bluetooth radio. Coexistence manager decision units may be designed synchronously to occur at preset times, or asynchronously as needed by the respective radios. The decision units may be structured to reduce latency. The decision units may be configured specifically for the Long Term Evolution radio and Bluetooth radios.

Claims

1. A method of wireless communication system, the method comprising:

generating an interrupt of a managed radio relating to an upcoming radio event;

collecting information for a notification event relating to the upcoming radio event within a time interval associated with the upcoming radio event; and

2. The method of claim 1 further comprising forming an asynchronous decision unit directly in response to generating the interrupt.

3. The method of claim 1 in which the sending the collected information comprises sending the collected information during a next available pre-scheduled synchronous decision unit.
