Method and device for transmitting uplink channel in wireless communication system

A method of receiving physical uplink shared channel (PUSCH) repetition using frequency hopping by a base station, the method comprising:

• transmitting frequency hopping interval information through higher layer signaling, wherein the frequency hopping interval information indicates a plurality of slots;
• transmitting frequency hopping indication information through downlink control information (DCI), wherein the frequency hopping indication information indicates whether to perform PUSCH frequency hopping;
• and
• receiving the PUSCH repetition using frequency hopping, based on the frequency hopping indication information,
• wherein receiving the PUSCH repetition using frequency hopping includes:
• identifying a frequency hop corresponding to a slot for the PUSCH repetition, based on the frequency hopping interval information, and
• receiving a PUSCH in the identified frequency hop in the slot for the PUSCH repetition.
