1. A method of transmitting an uplink (UL) signal by a user equipment (UE) in a wireless communication system, the method comprising:receiving, through a physical downlink control (PDCCH) signal, downlink control information (DCI) regarding a semi-persistent scheduling (SPS) physical uplink shared channel (PUSCH); and
transmitting an SPS PUSCH signal based on the DCI,
wherein transmitting the SPS PUSCH signal based on the DCI comprises:
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) the UE is configured for simultaneous PUSCH and physical uplink control channel (PUCCH) transmission:
transmitting uplink control information (UCI) through the SPS PUSCH signal, without simultaneously transmitting a PUCCH signal.
