Resource allocation method for performing transmission in unlicensed band, and device using same

A method of operating a terminal in a wireless communication system, the method comprising:

• receiving Downlink Control Information (DCI) for allocating a plurality of resource blocks (RBs) for transmitting a Physical Uplink Shared Channel (PUSCH);
• and
• transmitting the PUSCH to the base station through the plurality of resource blocks allocated through the DCI,
• wherein the DCI includes first bits for allocating at least one resource block set including the plurality of resource blocks for transmitting the PUSCH and second bits related to an interlaced allocation for the plurality of resource blocks,
• wherein the first bits are used for allocating the at least one resource block set included in an active bandwidth part (BWP),
• wherein the second bits are used for providing at least one interlace included in the interlaced allocation for the plurality of resource blocks,
• wherein at least one resource block included in each of the at least one interlace is arranged at a specific interval in the active BWP,
• wherein the at least one resource block set is continuously allocated within the active BWP based on the first bits,
• wherein the second bits are used for indicating the at least one interlace using different schemes based on a subcarrier spacing (SCS) configured to the active BWP, and
• wherein a number of the second bits varies depending on the SCS configured to the active BWP.

A base station configured to operate in a wireless communication system, the base station comprising:

• a communication module;
• and
• a processor configured to control the communication module,
• wherein the processor is configured to,
• transmit Downlink Control Information (DCI) for allocating a plurality of resource blocks (RBs) for transmitting a Physical Uplink Shared Channel (PUSCH),
• receive the PUSCH to the base station through the plurality of resource blocks allocated through the DCI,
• wherein the DCI comprises first bits for allocating at least one resource block set including the plurality of resource blocks for transmitting the PUSCH and second bits related to an interlaced allocation for the plurality of resource blocks,
• wherein the first bits are used for allocating the at least one resource block set included in an active bandwidth part (BWP),
• wherein the second bits are used for providing the at least one interlace included in the interlaced allocation for the plurality of resource blocks,
• wherein at least one resource block included in each of the at least one interlace is arranged at a specific interval in the active BWP,
• wherein the at least one resource block set is continuously allocated within the active BWP based on the first bits,
• wherein the second bits are used for indicating the at least one interlace using different schemes based on a subcarrier spacing (SCS) configured to the active BWP, and
• wherein a number of the second bits varies depending on the SCS configured to the active BWP.
