Abstract

A method of wireless communication is provided. The method includes reading, by a User Equipment (UE), system information of a plurality of cells on a first carrier frequency to obtain identification information of a plurality of Public Land Mobile Networks (PLMNs). The first carrier frequency is an unlicensed carrier frequency. The method further includes reporting, by an Access Stratum (AS) entity of the UE, the identification information of the plurality of PLMNs to a Non-Access Stratum (NAS) entity of the UE, selecting, by the NAS of the UE, one of the plurality of PLMNs as a selected PLMN, searching for the plurality of cells on the first carrier frequency during a cell selection procedure, and selecting a suitable cell belonging to the selected PLMN from the plurality of cells on the first carrier frequency as an outcome of the cell selection procedure.
