Method for transmitting and receiving signal in wireless communication system for supporting unlicensed band, and device for supporting same

A user equipment (UE) configured to transmit a Physical Uplink Shared Channel (PUSCH) in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
• receiving, via the at least one transceiver, Downlink Control Information (DCI) for scheduling a plurality of Physical Uplink Shared Channels (PUSCHs);
• obtaining, from the DCI, (i) a respective starting symbol index for each of the plurality of PUSCHs, among a plurality of starting symbol indices and (ii) information of a respective length for each of the plurality of PUSCHs, among a plurality of lengths;
• and
• transmitting, via the at least one transceiver, the each of the plurality of PUSCHs based on (i) the respective starting symbol index among the plurality of starting symbol indices and (ii) the respective length among the plurality of lengths,
• wherein a number of the plurality of PUSCHs is determined based on a number of combinations of starting symbol indices and lengths indicated by the DCI.
