Abstract

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.
