Packet size dependent link adaptation for wireless packet data

Abstract
In wireless packet data systems such as the Enhanced General Packet Radio Service (EGPRS), selective ARQ is used for error recovery over a radio link. In earlier work, the radio link control (RLC) performance is typically characterized in terms of the throughput and the size of the higher layer protocol data units (PDUs) or the packets to be transferred is ignored. We propose that the link adaptation be based on user perceived delay instead of the throughput
