Abstract: A method for avoiding interference in an idle mode and a method for receiving a public warning system message regardless of an operation mode when different wireless communication modules coexist in a terminal in a wireless communication system are provided. The method for controlling an idle mode of a terminal in a wireless communication system includes determining whether interference occurs between heterogeneous communication modules of the terminal; and limiting, if the interference occurs between the heterogeneous communication modules, camping on a corresponding frequency of the communication module in which the interference occurs. The terminal can maximally avoid the interference in the idle mode to operate without malfunction, and correctly receive the public warning system message regardless of the operation mode to enable the user to timely receive the corresponding message.

Abstract: The present disclosure provides a method for correcting an error caused by Hyper Frame Number (HFN) and Packet Data Convergence Protocol Sequence Number (PDCP SN) mismatch between a user equipment and base station when the user equipment fails in handover between cells in a wireless communication system. In addition, the present disclosure provides a handover procedure for a user equipment performing handover from a macro cell to a Closed Subscriber Group (CSG) cell shared by multiple operators in a wireless communication system. The present disclosure enables a user equipment and base station to perform communication without a malfunction after handover failure. For handover from a macro cell to a CSG cell shared by multiple operators, the present disclosure enables a user equipment to perform handover to an accessible cell.
