1. A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver; and
a processor comprising processor circuitry configured to:
emulate a first event of a set of events related to a set of cells including a serving cell and a neighbor cell in case that the UE is in a radio resource control (RRC) connected state and the first event is triggered in the UE,
determine an emulated first channel load metric of a set of emulated channel load metrics related to the emulated first event, the emulated first channel load metric including a reference signal received power (RSRP) for a cell reselection from the serving cell to the neighbor cell,
determine an actual first channel load metric of the set of the emulated channel load metrics related to the emulated first event, the actual first channel load metric including a RSRP for a handover from the serving cell to the neighbor cell,
identify a difference between the emulated first channel load metric and the actual first channel load metric, the difference being proportional to a coverage misalignment severity for the serving cell or the neighbor cell associated with measurements for the cell reselection or the handover of the UE, and
report, to a base station, information about the identified difference between the emulated first channel load metric and the actual first channel load metric,
wherein the emulated first event comprises the cell reselection of the UE from the serving cell to the neighbor cell.
