Method and device for transmitting or receiving radio signal in wireless communication system

A device for processing a signal for wireless communication, the device comprising:

• at least one memory configured to store one or more instructions;
• and
• at least one processor configured to execute the one or more instructions stored in the at least one memory,
• wherein the at least one processor is configured to, according to the execution of the one or more instructions, monitor control channel candidates in a bandwidth part (BWP) based on a control channel search space set (SS) configuration and a control resource set (CORESET) configuration, and obtain control information from a control channel detected as a result of monitoring the control channel candidates, and
• wherein a CORESET configured based on the CORESET configuration is associated with a control channel SS configured based on the control channel SS configuration, the BWP includes one or more subbands (SBs), and for monitoring the control channel candidates, the at least one processor is configured to configure each CORESET frequency resource area in each SB of the BWP based on a CORESET frequency resource area of a specific single SB of the BWP.

A wireless communication device comprising:

• a receiver;
• and
• at least one processor configured to control the receiver,
• wherein the at least one processor is configured to monitor control channel candidates in a bandwidth part (BWP) based on a control channel search space set (SS) configuration and a control resource set (CORESET) configuration, and obtain control information from a control channel detected as a result of monitoring the control channel candidates, and
• wherein a CORESET configured based on the CORESET configuration is associated with a control channel SS configured based on the control channel SS configuration, the BWP includes one or more subbands (SBs), and for monitoring the control channel candidates, the at least one processor is configured to configure each CORESET frequency resource area in each SB of the BWP based on a CORESET frequency resource area of a specific single SB of the BWP.

A method of transmitting a signal by a wireless communication device, the method comprising:

• selecting at least one of control channel candidates in a bandwidth part (BWP) based on a control channel search space set (SS) configuration and a control resource set (CORESET) configuration;
• and
• transmitting a control channel carrying control information in the selected at least one control channel candidate,
• wherein a CORESET configured based on the CORESET configuration is associated with a control channel SS configured based on the control channel SS configuration, the BWP includes one or more subbands (SBs), and the wireless communication device configures each CORESET frequency resource area in each SB of the BWP based on a CORESET frequency resource area of a specific single SB of the BWP.

A wireless communication device comprising:

• a transmitter;
• and
• at least one processor configured to control the transmitter,
• wherein the at least one processor is configured to select at least one of control channel candidates in a bandwidth part (BWP) based on a control channel search space set (SS) configuration and a control resource set (CORESET) configuration, and transmit a control channel carrying control information in the selected at least one control channel candidate, and
• wherein a CORESET configured based on the CORESET configuration is associated with a control channel SS configured based on the control channel SS configuration, the BWP includes one or more subbands (SBs), and the at least one processor is configured to configure each CORESET frequency resource area in each SB of the BWP based on a CORESET frequency resource area of a specific single SB of the BWP.
