Abstract: Disclosed is a method for a user equipment to transmit a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The user equipment may receive, from the base station, configuration information for PUSCH transmission and a physical downlink control channel (PDCCH) for scheduling repeated transmission of the PUSCH. Thereafter, the user equipment may determine one or more invalid symbols for the repeated transmission of the PUSCH, and may repeatedly transmit the PUSCH on symbols other than the determined symbols.
