Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for operating a user equipment (UE) in a wireless communication system is provided. The method includes receiving system information blocks (SIBS) of a first base station, performing a procedure for accessing a second base station that receives, from the first base station, information to be used to identify at least one SIB to be provided to the UE, and receiving the at least one SIB of the second base station.
