Abstract
A method for effecting timing synchronization within a multi-mode communication device is disclosed herein. The method includes configuring a host baseband processor of the multi-mode device to operate in accordance with a first wireless communications protocol of a first wireless communications system. A baseband co-processor of the device is also configured to operate in accordance with a second wireless communications protocol of a second wireless communications system. The method includes establishing, within the device, timing synchronization between the first and second communication systems on the basis of timing information transferred to the host baseband processor from the baseband co-processor.
