Method for transceiving data in unlicensed band and apparatus for same

An apparatus operating in a wireless communication system, the apparatus comprising:

• a memory:
• and
• at least one processor coupled with the memory,
• wherein the at least one processor is configured to:
• receive downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH), wherein the DCI comprises information regarding one of a plurality of predetermined listen before talk (LBT) types;
• perform an LBT operation with an LBT type identified based on the information;
• and
• transmit, based on the LBT operation, the PUSCH,
• wherein the information comprises N bits indicating one of the plurality of predetermined LBT types, wherein N is an natural number,
• wherein the N bits with a first value is mapped to a first LBT type among the plurality of predetermined LBT types, and
• wherein the N bits with a second value is mapped to a second LBT type among the plurality of predetermined LBT types.

A method for a base station (BS) in a wireless communication system, the method comprising:

• transmitting downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH), wherein the DCI comprises information regarding one of a plurality of predetermined listen before talk (LBT) types;
• and
• receiving the PUSCH in response to the DCI,
• wherein the information comprises N bits indicating one of the plurality of predetermined LBT types, wherein N is an natural number,
• wherein the N bits with a first value is mapped to a first LBT type among the plurality of predetermined LBT types, and
• wherein the N bits with a second value is mapped to a second LBT type among the plurality of predetermined LBT types.
