DATA PROCESSING METHOD FOR EFFICIENTLY ABANDONING A DATA BLOCK STORED IN A BUFFER BY DEFINING AN EXACT INTERFACE BETWEEN LAYERS

摘要

PURPOSE: A data processing method in a wireless communication system is provided to improve the processing performance of a data block by clearly defining an inter-layer interface.;CONSTITUTION: A PDCP(Packet Data Convergence Protocol) layer generates PDCP PDU 1 corresponding to the PDCP SDU(Service Data Unit) 1 and the serial number 1 of a PDCP PDU 1(S301). An RLC(Radio Link Control) layer stores an RLC SDU 1 corresponding to the PDCP PDU 1 and serial number 1 in a transmission buffer(S302). The PDCP generates a PDCP PDU 2 corresponding to a PDCP SDU 2 and the serial number 2 of the PDCP PDU 2(S303). The RLC layer stores an RLC SDU 2 corresponding to the PDCP PDU 2 and serial number 2 in the transmission buffer(S304).;COPYRIGHT KIPO 2010
