The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The disclosure is to provide a user equipment (UE) in a wireless communication system, the UE comprises a transceiver, and a processor configured to emulate a first event of a set of events related to the set of cells including a first cell and a second cell, estimate a first attribute of a set of attributes of the set of cells based on a result of the emulated first event, determine an emulated first channel load metric of a set of emulated channel load metrics related to the emulated first event, determine an actual first channel load metric of the set of the emulated channel load metrics related to the emulated first event, compare the emulated first channel load metric and the actual first channel load metric, and report, to a base station, a compared result of the emulated first channel load metric and the actual first channel load metric, wherein the emulated first event comprises a cell reselection or handover of the UE from the first cell to the second cell.
