1. A method of controlling a radio frequency integrated chip (RFIC) of a terminal in a wireless communication system, the method comprising:
detecting an event for changing a mode of the RFIC from a first mode for receiving a signal from a serving cell to a second mode for receiving a signal from a neighbor cell;
generating a control command including a configuration information for a composition element of the RFIC after the event is detected;
mapping the generated control command to information of the neighbor cell;
storing the control command and the information of the neighbor cell in a table;
storing an index of the table in which the generated control command and the information of the neighbor cell are stored;
in response to detecting a next event for changing the mode of the RFIC to receive a signal from the neighbor cell, obtaining the stored control command by using the information of the neighbor cell;
configuring the RFIC to change the mode of the RFIC from the first mode to the second mode based on the obtained control command; and
receiving the signal from the neighbor cell by using the configured RFIC, wherein the second mode corresponds to a frequency or a radio access technology (RAT) for the neighbor cell,
wherein the event is detected between a start time point of a predetermined duration for measuring the signal from the neighbor cell and an end time point of the predetermined duration,
wherein the control command corresponds to a serial peripheral interface (SPI) control command, and
wherein the SPI control command comprises at least one of address information of the RFIC, configuration information regarding a composition element of at least one transmission path of the RFIC, or a composition element of at least one reception path of the RFIC.
