ABSTRACT:
Techniques to enable efficient operation of co-located WLAN and Bluetooth devices are described. A station (e.g., a cellular phone or a laptop computer) determines the activity of a Bluetooth device and ascertains idle periods of the Bluetooth device. The station communicates with an access point in a WLAN during the idle periods of the Bluetooth device. The station may operate in a power save mode with the access point, send a poll frame to the access point during an idle period, and retrieve the buffered data from the access point during the idle period. The station may also operate in an unscheduled APSD mode with the access point, send a trigger frame to the access point during an idle period to start a service period, and exchange data with the access point during the service period.
