Abstract
A method for handling discarding of a sequence of service data units in a communications system is disclosed. The sequence of service data units includes at least a last discarded service data unit (SDU). When a protocol data unit (PDU) containing a length indicator of the last discarded SDU contains no new SDUs, the method includes creating a move receiving window super field (MRW SUFI), setting a NLENGTH field of the MRW SUFI to 0, setting a last sequence number move receiving window field (SN_MRWLENGTH) to a sum of one plus a sequence number (SN) of the PDU containing the length indicator of the last discarded SDU, and issuing the MRW SUFI.
