Method for transmitting and receiving signals in wireless communication system and apparatus for supporting same

An apparatus configured to receive downlink control information (DCI) in a wireless communication system, the apparatus comprising:

• a processor;
• and
• at least one memory storing instructions for the processor,
• wherein when executed, the instructions cause the processor to:
• identify at least one first subband being available for reception of a signal, among a plurality of subbands included in an unlicensed band;
• monitor, based on a control resource set (CORESET) configured over the plurality of subbands and the at least one first subband, a first physical downlink control channel (PDCCH) candidate among a plurality of PDCCH candidates configured in the CORESET;
• and
• receive the DCI based on the monitoring,
• wherein based on at least a part of a second PDCCH candidate, among the plurality of PDCCH candidates, is included in at least one second subband, among the plurality of subbands, identified as not available for the reception of the signal, the second PDCCH candidate is not monitored.

An apparatus configured to transmit downlink control information (DCI) in a wireless communication system, the apparatus comprising:

• a processor;
• and
• at least one memory storing instructions for the processor,
• wherein when executed, the instructions cause the processor to:
• perform a channel access procedure (CAP) for determining whether at least one first subband is available for transmission of a signal among a plurality of subbands included in an unlicensed band, and
• transmit, based on a control resource set (CORESET) configured over the plurality of subbands and the at least one first subband, the DCI in a first physical downlink control channel (PDCCH) candidate among a plurality of PDCCH candidates configured in the CORESET, and
• wherein based on at least a part of a second PDCCH candidate, among the plurality of PDCCH candidates, is included in at least one second subband, among the plurality of subbands, identified as not available for the transmission of the signal, the DCI is not transmitted on the second PDCCH candidate.
