During reception of a higher-layer packet, segmented into lower-layer frames, a receiver will appropriately determine if a lower-layer frame was correctly received. If a lower-layer frame is not correctly received, and the maximum number of NAKs have been sent, the lower-layer frame is categorized as aborted. Once a frame has been categorized as aborted, the receiver determines an RLP frame corresponding to the higher layer packet boundary, sets V(N) to a next missing link-layer frame after a higher-layer packet boundary and pushes frames up to V(N) to the higher layer.

Selective retransmission of data

An apparatus and method that optimizes the data rate for forward link data transmissions in a spread-spectrum communications systemis provided. The spread-spectrum communications systemcomprises a wireless infrastructure, at least one wireless mobile receiving device, and an radio frequency (RF) forward linkbetween the wireless infrastructureand the wireless mobile receiving device. The data rate of the RF forward linkis optimized in the wireless infrastructureby estimating or measuring the bottleneck link speed of the data transmission and adjusting the data rate for the RE forward linkaccording to several embodiments of a data rate optimization algorithm. The algorithm creates an optimum range for the data rate of the RF wireless linkwhich maximizes system capacity and reduces transmission delays to the wireless mobile receiving device
