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 a long term evolution (LTE). An operating method of a base station (BS) in a communication system supporting a time division multiplexing (TDD) scheme is provided. The operating method includes transmitting, to a user equipment (UE) which uses a second radio access technology (RAT) different from a first RAT used by other BS different from the BS, information related to downlink (DL) and uplink (UL) timing of the other BS and margin information for synchronizing DL and UL timing of the first RAT with DL and UL timing of the second RAT, wherein the information related to the DL and UL timing of the other BS is received from the other BS, or predicted by the BS.
