SYSTEM FOR PROCESSING DATA UNITS OF A RADIO PROTOCOL LAYER

摘要

The present invention relates to a system for processing data units of a radio protocol layer. A reordering buffer for reordering data blocks is provided for each logical channel. Unnecessary data transmission delay is prevented and transmission efficiency at a radio interface is enhanced because the present invention is directed to reordering data units of a MAC-d SDU or MAC-d PDU, compared to the conventional art in which the reordering operation is performed according to the units of a MAC-e PDU.
