Abstract
A method, a transmitter and a computer program product for processing data units at the transmitter are disclosed. In one embodiment, data units are transmitted to a receiver according to a protocol and with respective sequence numbers. The protocol indicates that the receiver is to use a reordering window to determine whether a data unit which is newly received from the transmitter is a new or repeated data unit the data stream by comparing the sequence numbers of the newly received data unit and a previously received data unit. A status report is received and based thereon, the sequence number of a next data unit to be transmitted in a new cell following a handover is selectively adjusted such that the next data unit will be determined to be a new data unit. The next data unit is transmitted with the adjusted sequence number to the receiver.
