Abstract: Disclosed are a method of transmitting and receiving a physical downlink shared channel in a wireless communication system and an apparatus supporting the method. More specifically, the method performed by a user equipment may comprise transmitting, to a base station (BS), capability information including first information indicating support for a PDSCH repetition-related operation; receiving, from the BS, an higher layer signal including second information for configuring whether to enable the PDSCH repetition-related operation; receiving Downlink Control Information (DCI) related to reception of a PDSCH repetition from the BS when the second information is configured as enable; and receiving the PDSCH repeatedly from the BS based on the DCI.

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.

Abstract: The disclosure proposes a method for transmitting/receiving data in a wireless communication system and apparatus for supporting the same. Specifically, a method of transmitting an uplink data channel by a user equipment (UE) in a wireless communication system comprises receiving, from a base station, first downlink control information for scheduling an uplink data channel in an nth transmission time unit, receiving, from the base station, second downlink control information for scheduling an uplink data channel in an n+kth transmission time unit, and when information by the first downlink control information is inconsistent with information by the second downlink control information, transmitting an uplink data channel which is based on the first downlink control information to the base station, wherein the second downlink control information may be discarded by the UE.

Abstract: A method of receiving Downlink (DL) data by a User Equipment (UE) in a wireless communication system. The method includes: receiving information related to a number of repetitions of the DL data which is repeatedly transmitted in (i) at least one first Transmission Time Interval (TTI) included in a first subframe, and in (ii) at least one second TTI included in a second subframe that is after the first subframe; and receiving the DL data based on the number of repetitions of the DL data. If a Transmission Mode (TM) for the first subframe is different from a TM for the second subframe, then the UE does not receive the DL data in the at least one second TTI.
