1. A method performed by a terminal, the method comprising:
receiving a control message including configuration information associated with a bearer via a radio resource control (RRC) signaling;
identifying whether a bearer type is changed from a split bearer to a non-split bearer based on the configuration information; and
retransmitting, for data recovery, data for which a successful transmission has not been confirmed without packet data convergence protocol (PDCP) re-establishment, if the bearer type is changed from the split bearer to the non-split bearer.
