The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate beyond a 4th generation (4G) communication system, such as long term evolution (LTE). The disclosure relates to a method performed by a base station in a wireless communication system, which may include: transmitting a radio resource control (RRC) message including reconfigurable intelligence surface (RIS) codebook configuration information to an RIS controller; determining a format of RIS control information based on the number of RIS codeword indexes; generating the RIS control information based on the determined format; and transmitting the generated RIS control information to the RIS controller.
