<p>Systems and methods are described for controlling a reference oscillator shared by multiple subsystems of a communications system and arbitrating usage of the reference oscillator among these subsystems. By changing the properties of the reference oscillator (e.g., by tuning the reference oscillator) according to the needs of particular subsystem(s), the communications system can configure the reference oscillator to meet the specification requirements of these particular subsystem(s) and can later reconfigure the reference oscillator to meet the needs of other subsystems. Further, the controller can configure the subsystems based on parameters that impact multiple subsystems (e.g., by implementing geographic awareness, spectrum occupation awareness, and availability of Assisted GPS (AGPS) functionality) to achieve further optimization of the communications system.</p> |
