Abstract: A method of transmitting an uplink (UL) signal by a user equipment (UE) in a wireless communication system, where the method includes: receiving, through a physical downlink control (PDCCH) signal, downlink control information (DCI) regarding a semi-persistent scheduling (SPS) physical uplink shared channel (PUSCH); and periodically transmitting an SPS PUSCH signal based on the DCI. Periodically transmitting the SPS PUSCH signal based on the DCI includes: in a state in which (i) the SPS PUSCH signal is subslot-based, (ii) a demodulation reference signal (DMRS) pattern field included in the DCI is set to a first value, and (iii) simultaneous transmission of a physical uplink control channel (PUCCH) and the PUSCH is configured for the UE: transmitting uplink control information (UCI) through the SPS PUSCH signal, without simultaneously transmitting a PUCCH signal.
