A pre-5G or 5G communication system for transmitting channel state information (CSI) by determining CSI transmission configuration information that comprises transmission times k of periodic CSI report in one subframe and transmitting CSI report according to the CSI transmission configuration information. Thereby, transmission efficiency of uplink control information (UCI) in a higher frequency spectrum resource environment of 5G technology may be improved and transmission efficiency and transmission performance of UCI may be ensured by introducing a smaller time unit for data scheduling and configuring a smaller CSI report period.
