ABSTRACT:
A method and system for synchronization of link layer windows in a wireless communications system is disclosed. At a transmitter in the wireless communications system, the transmitter transmits a plurality of frames in a transmitter's link layer window, wherein each frame comprises segments and sends a request for an acknowledgement of the plurality of frames to a receiver. Then the transmitter determines a last transmitted segment of an eldest frame of the plurality of frames in the transmitter's link layer window, if a response to the request is not received within a specified time period and sets a synchronization indicator in the determined last transmitted segment of the eldest frame. Finally, the transmitter transmits the determined last transmitted segment of the eldest frame with the synchronization indicator set to the receiver.
