Patent ID: 8184535

Claim:
A method for controlling data flow of co-localized a wireless local area network (WLAN) device and a bluetooth (BT) device, comprising: deriving an available medium time for the WLAN device to communicate with a peer WLAN device based on schedule data forwarded by the BT device; transmitting a first data from the WLAN device to the peer WLAN device if the BT device becomes inactive and if the available medium time is greater than a threshold time, wherein the first data indicates that the WLAN device is to come out of a power save (PS) mode, wherein the threshold time is equivalent to (2+0.5*buffer size of the peer WLAN device) multiplied by time necessary to successfully transmit and receive a highest data packet size at current communication rate between the WLAN device and the peer WLAN device and further added by time necessary to transmit a null frame and receive an acknowledgement signal at the current communication rate; and transmitting a second data from the WLAN device to the peer WLAN device if the available medium time is less than the threshold time, wherein the second data indicates that the WLAN device is to enter the PS mode.
