Abstract

A bearer reconfiguration method performed by a User Equipment (UE) in a wireless communication system supporting a multi-bearer is provided. The bearer reconfiguration method includes, if the UE performs a bearer reconfiguration from a single bearer to the multi-bearer, reordering Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) received through the multi-bearer, using a timer after a completion of the bearer reconfiguration, and processing the reordered PDCP PDUs into at least one PDCP Service Data Unit (SDU). The method may also include, if the UE performs bearer reconfiguration from the multi-bearer to the single bearer, reordering PDCP PDUs received through the multi-bearer, using a timer until a predetermined condition is satisfied, and processing the reordered PDCP PDUs into at least one PDCP SDU.

Description

technical field [0001] The present disclosure relates to methods and apparatuses for transmitting and receiving data using multiple carriers in a mobile communication system. Background technique [0002] Mobile communication systems have been developed to provide communication services while ensuring mobility of users. Recently, mobile communication systems have reached a stage where they can provide not only voice communication services but also high-speed data communication services. [0003] In recent years, the Long Term Evolution (LTE) system proposed by the Third Generation Partnership Project (3GPP) is providing its service in many countries as one of the next generation mobile communication systems. The LTE system is a technology for realizing high-speed packet-based communication with a transfer rate of about 100 Mbps. [0004] Recently, commercialization of an LTE-Advanced (LTE-A) communication system whose transfer rate has been improved by combining various ne...
