Method for transmitting uplink shared channel in wireless communication system and device using same

A user equipment (UE) configured to transmit a physical uplink shared channel (PUSCH) to a base station in a wireless communication system, the UE comprising:

• a communication module configured to receive a radio resource control (RRC) signal comprising configuration information relating to a semi-static uplink symbol, a flexible symbol, and a downlink symbol from the base station, receive a physical downlink control channel (PDCCH) for scheduling PUSCH transmission comprising at least one PUSCH repetition from the base station, or transmit PUSCH repetition to the base station;
• a memory configured to store a control program and data used by the UE;
• and
• a processor configured to determine whether at least one of a required number of symbols for transmission of the PUSCH repetition corresponds to a case in which a PUSCH repetition is not allowed to be transmitted, and control transmission of the PUSCH repetition on the basis of the determination on whether to correspond to the case in which the PUSCH repetition is not allowed to be transmitted,
• wherein the case in which the PUSCH repetition is not allowed to be transmitted comprises a case in which at least one of the symbols is a symbol designated as a semi-static downlink symbol by the configuration information.
