Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.
