Abstract: A disclosure of the present specification provides a method for performing random access by a terminal. The method may comprise the steps of: selecting, by the terminal, a first resource among a plurality of resources for a physical random access channel (PRACH), wherein the plurality of resources exist for each numerology, and the numerology is defined by a cycle prefix (CP) length and a subcarrier spacing; and transmitting, by the terminal, the PRACH on the first resource through a first numerology when the selected first resource is for the first numerology.

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.
