Abstract:
1. A method for processing received data in a mobile communication system, the method comprising: receiving data protocol data units (PDUs) from a transmitting side, wherein each of the data PDUs has a header comprising a sequence number; storing the received PDUs in a buffer; receiving a control message for shifting a starting value of a receiving window, wherein the control message signals a starting sequence number of a first PDU for which an acknowledgement is expected; checking whether one of the stored PDUs is a buffered preceding PDU, wherein the buffered preceding PDU has a sequence number that precedes the starting sequence number; reassembling at least one successfully received service data unit (SDU) from the buffered preceding PDU for delivery to a higher layer; releasing the buffered preceding PDU; and shifting the starting value of the receiving window to a next value of a sequence number of a last SDU that was reassembled for delivery to the higher layer.
