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.

Abstract translation: 公开了一种用于无线通信系统中的链路层窗口的同步的方法和系统。 在无线通信系统中的发射机处，发射机在发射机的链路层窗口中发射多个帧，其中每个帧包括分段并且向接收机发送对多个帧的确认的请求。 然后，如果在指定时间段内没有接收到对该请求的响应并且在所确定的最后传输的段中设置同步指示符，则发射机确定发射机的链路层窗口中的多个帧中的最年长帧的最后传输段 最年长的框架。 最后，发射机将确定的最后一个发送的具有同步指示符的最旧帧的发送段发送给接收机。
