A method performed by a user equipment (UE) is provided. In the method, at least one idle mode measurement configuration is received from a cell of a serving radio access network (RAN) via a downlink control signaling. Whether a small data transmission (SDT) procedure is ongoing while the UE is staying in a radio resource control (RRC) inactive state is determined. Whether to perform an idle mode measurement in the RRC inactive state according to the at least one idle mode measurement configuration is determined based on a determination result of whether the SDT procedure is ongoing.
