RLC DATA TRANSMITTING/RECEIVING METHOD AND APPARATUS IN A MOBILE COMMUNICATION SYSTEM

摘要

A data transmitting/receiving method in an RLC layer and an apparatus therefor are provided to inform of the segment state of an SDU included within an RLC PDU by using only segment indication information of single bit. Whether several SDUs are included within a PDU or not is determined(701). If the SDUs are included within the PDU, whether the final SDU is segmented or not is determined(711). If the final SDU is segmented, an ESF is set as a segment(721). If the final SDU is not segmented, the ESF is set as a non-segment(722).
