System and method for WLAN and SCO bluetooth coexistence

摘要

In a wireless communication device having collocated Bluetooth and WLAN systems, wireless communication in a device having Bluetooth and WLAN systems, the device monitors for beacon transmission from an access point for a threshold number of access point beacon intervals when an SCO Bluetooth link is active. Once a threshold number of beacon intervals have passed without receiving a beacon transmission from the access point, the WLAN module sends a PS-Poll message to the access point to maintain the link and so that any queued data for the device can be transmitted.

1. A method for wireless communication in a device having Bluetooth and wireless local area network (WLAN) modules, comprising:
determining existence of a synchronous connection-oriented (SCO) Bluetooth link; monitoring WLAN receptions for a beacon transmission from an access point for a threshold number of access point beacon intervals; and sending a power save poll (PS-Poll) message to the access point after the threshold number of access point beacon intervals has passed without receiving a beacon transmission from the access point when the SCO Bluetooth link is active.
