Abstract: A user equipment (UE) configured to determine, for each radio access technology (RAT) of a plurality of RATs, a first list of bands on which a public land mobile network (PLMN) is expected to be deployed and a second list of bands including bands not included in the first list, wherein the first list is determined based on a region where the UE is currently located and PLMN deployment information, select a search pattern for performing a cell search based on a current UE scenario, perform a first phase of the cell search and when the first phase of the cell search is unsuccessful and no cell is selected, perform a second phase of the cell search by either scanning frequencies included in the second list of bands for the first priority RAT or scanning frequencies included in the first list of bands for a second priority RAT.
