1. A method for performing a physical uplink shared channel (PUSCH) transmission by a user equipment (UE) in a wireless communication system, the method comprising:
receiving downlink control information (DCI) scheduling of the PUSCH, wherein the DCI includes information for a start symbol of the PUSCH; and
transmitting the PUSCH based on the DCI,
wherein a cyclic prefix (CP) extension is performed during a specific interval preceding a first symbol for the PUSCH,
wherein the specific interval is determined based on a first variable and a second variable,
wherein the first variable has a value of one of 25.10-6, 16.10-6+TTA or 25.10-6+TTA,
wherein the TTA is a timing advance between a downlink and an uplink, and
wherein the second variable has a value for a subcarrier spacing.
