Abstract: The present disclosure relates to a fifth generation (5G) communication system or a sixth generation (6G) communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). In a wireless communication system, a method performed by a base station includes identifying a delay time caused by a radio unit (RU) buffer, determining an RIS offset value for synchronization of signals transmitted to a reconfigurable intelligent surface (RIS), based on the delay time caused by the RU buffer, transmitting, to the RIS, a first signal to be transmitted to a terminal through a reflection plane of the RIS at a first time point, and transmitting, to the RIS, a second signal for controlling a reflection pattern of the RIS at a second time point to which the RIS offset value is applied.
