Abstract: A method and apparatus for controlling a Radio Frequency Integrated Chip (RFIC) in a wireless communication system are provided. The method includes detecting an event for changing a signal receiving cell of the RFIC, determining whether a Serial Peripheral Interface (SPI) control command for a target cell is pre-stored based on information of the target cell, and configuring the RFIC based on the pre-stored SPI control command if the SPI control command for the target cell is pre-stored.

Abstract: A method and apparatus of searching for an operator network in a multi-Radio Access Technology (RAT) environment are provided. The method, calculating a length of a sleep interval to perform background Public Land Mobile Network (PLMN) searching, comparing the length of the sleep interval with a predetermined reference parameter, if the length of the sleep interval is larger than the reference parameter, performing background PLMN searching of a passive RAT during the sleep interval, and if the length of the sleep interval is equal to or smaller than the reference parameter, performing background PLMN searching of an active RAT during the sleep interval.
