    Abstract: A method for transmitting/receiving data in a wireless communication system and a device for supporting same are presented. Particularly, a method by which a terminal receives a physical downlink shared channel (PDSCH) in a wireless communication system comprises the steps of: receiving, from a base station, downlink control information (DCI) for scheduling the PDSCH in a nth transmission time unit; and determining whether the PDSCH is received on the basis of the DCI, wherein the DCI includes information for indicating whether a demodulation reference signal (DMRS) for the PDSCH exists in the nth transmission time unit.

    Abstract: A method of transmitting uplink (UL) control information for a user equipment (UE) for supporting a plurality of TTI lengths, a plurality of subcarrier spacing, or a plurality of processing times in a wireless communication system is performed by the UE and includes mapping the UL control information to a radio resource in a TTI including two or three symbols, the UL control information including HARQ-ACK, a rank indicator (RI), a channel quality indicator (CQI), or a precoding matrix indicator (PMI), and transmitting the UL control information to a base station, wherein, when there is no symbol to which a DMRS is mapped in the TTI, HARQ-ACK is mapped to a first symbol in the TTI in descending order from a highest frequency index resource element (RE) and the RI is mapped to the other symbol in the TTI in descending order from a highest frequency index RE.

    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.
