Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method of a user equipment (UE) is provided, which the method comprises receiving, from a base station (BS), configuration information associated with at least one non-cell defining-synchronization signal block (NCD-SSB). The method comprises identifying configurations for the at least one NCD-SSB based on the received configuration information, wherein the configurations for the at least one NCD-SSB includes configuration of a frequency domain, configuration of a period and configuration of a time domain for the at least one NCD-SSB. The method comprises receiving the at least one NCD-SSB on a resource based on the identified configurations.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present disclosure provides a user equipment (UE) in a wireless communication system and a method performed by the UE. The method includes: receiving a primary synchronization signal (PSS) and a secondary synchronization signal (SSS): receiving a physical broadcast channel block (PBCH), wherein the primary synchronization signal, the secondary synchronization signal and the PBCH constitute a synchronization signal and PBCH block (SSB).

Abstract: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method may comprises receiving, from a base station, a synchronization signal/physical broadcast channel (SS/PBCH) block on a PBCH, identifying a frequency band on which the SS/PBCH block is received, in case that the frequency band is a first frequency band, determining configuration information for a control resource set (CORESET) for a Type0 physical downlink control channel (PDCCH) search space set based on a minimum channel bandwidth of the first frequency band, and in case that the frequency band is a second frequency band including a n79 frequency band, determining the configuration information for the CORESET corresponding to the n79 frequency band.
