The present invention is a novel and improved method and system that prevents RLP3E from generating unnecessary NAKs, thus preventing unnecessary data frame retransmissions. The present invention is efficient, neither delaying the delivery of data frames to the higher data services layer nor delaying the delivery of necessary NAKs to the multiplex sublayer. Additionally, the present invention can be implemented with minimal changes to an existing RLP3E implementation. The present invention is applicable to systems such as cdma2000, W-CDMA, and EDGE, wherein data is transferred using an ARQ (automatic request for retransmission) mechanism, and wherein data packets are sometimes received in an order different from that in which they were transmitted. The present invention utilizes a new mechanism interposed between the multiplex sublayer and the RLP3E layer for all incoming traffic. The purpose of this sublayer, frame reordering sublayer 346, is to reorder the received packets into the opackets into the order in which they were transmitering them to RLP3E layer 344.
