Segmentation and reassembly receiver operation

A method for eliminating useless waiting for lost data units in a segmentation and reassembly (SAR) receiver operation is disclosed. The SAR receiver checks for any missing data units upon receiving a transmission of a plurality of data units in a predetermined sequence, storing all received data units following a first missing data in the SAR receiver, starting an abort timer for every missing data unit and delivering the stored data units between a first missing data unit and a second missing data unit if the abort timer for the first missing data unit has expired and the abort timer for the second missing data unit has not expired.
