1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a radio resource control (RRC) message including information configuring a measurement report for an uplink packet data convergence protocol (PDCP) packet delay per data radio bearer (DRB), wherein the information includes a list of DRBs to be measured and an uplink packet for a quality of service (QoS) flow is mapped to a DRB at a service data adaptation protocol (SDAP) layer;
performing a measurement of the uplink PDCP packet delay for each DRB in the list of DRBs based on the information, wherein the uplink PDCP packet delay for each DRB is measured based on a delay from an uplink packet arrival at a PDCP upper service access point (SAP) until a transmission of an uplink packet is available; and
transmitting, to the base station, a result of the measurement based on the information.
