Abstract: A method for transmitting a physical uplink shred channel (PUSCH) by a terminal in a wireless communication system according to an embodiment of the present specification comprises the steps of: receiving downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH); and transmitting the physical uplink shared channel (PUSCH) on the basis of the DCI. The format of the DCI is DCI format 0_0. On the basis that spatial relation RS information for transmission of the physical uplink shared channel (PUSCH) is not configured, the physical uplink shared channel (PUSCH) is transmitted on the basis of spatial relation quasi-colocation (QCL) RS information of a predefined control resource set (CORESET).
