Methods and apparatus for coexistence of wireless subsystems in a wireless communication device

摘要

Methods and apparatus to mitigate interference among multiple wireless subsystems of a wireless communication device are described. A host processor obtains configurations for a plurality of wireless subsystems and evaluates whether potential or actual coexistence interference exists between two or more of the wireless subsystems. The host processor provides configuration information and link quality reporting parameters to and obtains link quality reports from at least two wireless subsystems. When link quality for at least one wireless subsystem fails a set of link quality conditions, the host processor adjusts data requirements for applications that communicate through one or more of the wireless subsystems and/or adjusts radio frequency operating conditions for one or more of the wireless subsystems to mitigate interference among the wireless subsystems.

1. A wireless communication device comprising:
a processor; a first wireless subsystem coupled to the processor; and a second wireless subsystem coupled to the processor and to the first wireless subsystem wherein the processor is configured to:
obtain a first wireless subsystem configuration and a second wireless subsystem configuration for the first wireless subsystem and the second wireless subsystem respectively;evaluate whether the first and second wireless subsystem configurations indicate potential or actual coexistence interference between the first and second wireless subsystems; andwhen the first and second wireless subsystem configurations indicate potential or actual coexistence interference between the first and second wireless subsystems:
provide information of the first wireless subsystem configuration to the second wireless subsystem;provide information of the second wireless subsystem configuration to the first wireless subsystem;provide link quality reporting parameters to the first and second wireless subsystems;obtain link quality reports from the first and second wireless subsystems; andwhen a link quality of the second wireless subsystem fails a set of link quality conditions, adjust data requirements for one or more applications that generate or consume data packets communicated using the first wireless subsystem.
