Abstract
The present disclosure relates to a method and apparatus for transmitting and receiving data in a wireless communication system. A method, performed by a terminal dual-connected to a master base station and a secondary base station in a wireless communication system, of configuring an assistance information bit for local cache (AILC) bit includes receiving, from the master base station, a radio resource control (RRC) reconfiguration message including AILC bit configuration information (ailc-BitConfig), configuring an AILC bit of a packet data convergence protocol (PDCP) data packet data unit (PDU) based on at least one of a terminating base station of a data radio bearer (DRB) through which the PDCP data PDU is transmitted, whether the PDCP data PDU includes a service data unit (SDU) to be transmitted to a local cache, whether the DRB is configured with evolved universal terrestrial radio access (E-UTRA) PDCP or New Radio (NR) PDCP, or a PDCP sequence number (SN) of the PDCP data PDU, and transmitting, to the terminating base station, the PDCP data PDU in which the AILC bit is configured.
