RADIO COMMUNICATION SYSTEM HAVING RLC(RADIO LINK CONTROL) HIERARCHY OF TRANSPARENT MODE, AND DATA PROCESSING METHOD IN THE RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a data transmission device in a radio communication system having RLC hierarchy of transparent mode, and data processing method in the data transmission device. SOLUTION: In this invention, a service data unit transmitted from the upper hierarchy is stored and the information for the number and the size of PDUs, is received from MAC(Media Access Control). The service data unit is segmented from protocol data units or units of pieces and sizes corresponding to the received information in the RLC hierarchy by the information. The protocol data units or the units are transmitted to a receiver.
