Abstract: Disclosed is a method by which a terminal transmits a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The terminal can receive, from the base station, configuration information for allocating a resource for transmitting a transport block (TB) through the PUSCH, and map the TB to a plurality of slots constituting the resource on the basis of the configuration information. Thereafter, the terminal can transmit the TB on the plurality of slots through the PUSCH.
