Abstract:
1. A method for generating a Media Access Control Protocol Data Unit (MAC PDU) in a mobile communication system, the method comprising: checking Logical Channel Identifiers (LCIDs) of Media Access Control Service Data Units (MAC SDUs) to be multiplexed; determining the length of a Length Field (LF) for each of the MAC SDUs, referring to LF lengths predetermined for the LCIDs; generating a MAC header including the LCIDs and LFs of the determined lengths for the MAC SDUs; and generating a MAC PDU by attaching the MAC header to payload including the MAC SDUs, wherein the generating of the MAC header comprises, if a padding size required for the MAC PDU generation, calculated assuming the absence of a last LF in the MAC header, is larger than the length of the last LF, including the last LF in the MAC header, recalculating the required padding size taking into account the inclusion of the last LF, and adding a padding according to the re-calculated padding size.
