The present specification proposes a method for transmitting and receiving a physical downlink shared channel (PDSCH) in a wireless communication system and a device supporting the same. More specifically, the method performed by a user equipment includes receiving, from a base station, a higher layer signal including first information about a configuration of an operation related to a PDSCH repetition, receiving, from the base station, second information related to a number of symbols of a control region, receiving, from the base station, downlink control information (DCI) including information related to a PDSCH repetition number based on the second information, and repeatedly receiving, from the base station, the PDSCH based on the DCI, wherein when the control region is configured with a specific number of symbols, a transmission time unit related to the control region is not included in transmission time units for a PDSCH repetition reception.
