Abstract: A method, by a terminal, of performing a random access in a wireless communication system is provided. The method includes identifying a random access occasion configured for an active uplink (UL) bandwidth part (BWP) of a serving cell and when the serving cell is a special cell (SpCell) and an identity (ID) of an active downlink (DL) BWP does not correspond to an ID of the active UL BWP, switching the active DL BWP to a DL BWP with ID corresponding to the ID of the active UL BWP, based on BWP configuration information for the serving cell, and performing a random access on the switched DL BWP.
