Patent ID: 8233470

Claim:
A multi-radio wireless communication device comprising: a Bluetooth (BT) radio module to establish a BT link with a BT device; and a wireless-network radio module to generate a frame sync pulse associated with a frame of an OFDMA wireless network link and to provide the frame sync pulse to the BT radio module, wherein when the BT link is established prior to the wireless network link, the BT radio module is configured to adjust a master clock signal associated with the BT link by a predetermined step size before each first BT transmission of a BT interval in response to the frame sync pulse to shift positions of BT slots of the BT interval until a time difference between subsequent frame sync pulses and a synchronization reference point of one of the BT slots of the BT interval is reduced to less than a predetermined value, wherein the predetermined step size is no greater than a maximum value that the BT device is configured to adjust its slave clock to allow the BT link to be maintained with the BT device during the adjustment of the master clock signal, and wherein when the BT link is not established prior to the wireless network link, the BT radio module establishes the BT link to be initially synchronized with the wireless network link such that the time difference between subsequent frame sync pulses and a synchronization reference point of one of the BT slots of the BT interval is less than the predetermined value.
