               1. A method performed by a terminal, the method comprising: 
            receiving a system information block (SIB) from a base station; 
                in case that the received SIB is a SIB4, obtaining, from the SIB4, first synchronization signal/physical broadcast channel block measurement timing configuration (SMTC) information for a frequency different from a serving cell frequency, wherein the first SMTC information includes a parameter indicating a first periodicity; 
                in case that second SMTC information for the frequency is included in the SIB4, identifying time configuration for a synchronization signal/physical broadcast channel (SS/PBCH) block measurement, based on a second periodicity identified from the second SMTC information and a timing offset and a duration identified from the first SMTC information for the frequency; and 
                performing the SS/PBCH block measurement for an inter-frequency cell indicated by a physical cell ID (PCI) list included in the second SMTC information, based on the identified time configuration, 
                wherein the PCI list indicates the inter-frequency cell with the second periodicity longer than the first periodicity.
