摘要： The present disclosure relates to a 5G or 6G communication system for supporting a data transmission rate higher than that of a 4G communication system, such as LTE. A transmission or reception method of a terminal in a wireless communication system may comprise the steps of receiving a synchronization signal block (SSB) from a base station on the basis of blind detection, on the basis of the received SSB, identifying information on an SSB group to which the SSB belongs, wherein the SSB group is related to a first frequency domain, on the basis of the information on the SSB group, identifying a second frequency domain corresponding to at least one other SSB group, and receiving at least one SSB belonging to the at least one other SSB group from the base station on the basis of the second frequency domain.
