Alternatively, the transmitter uses the next robust TF for the first retransmission.

Abstract: A mobile device includes a communications protocol stack including a MAC layer and TCP layer separated by an IP layer. A cross-layer coordination module parallel to the communications protocol stack is coupled to both the MAC layer and TCP layer. The MAC layer generates a message sent to the cross-layer coordination module indicating that the mobile device is about to engage in a communications handover from a first base station to a second base station.

If the mobile device is operating as a TCP receiver, the TCP layer sends a TCP ACK message to a TCP sender having an advertised window size set to a zero value so as to cause the TCP sender to freeze a connection and state during communications handover.
