Method and device for transmitting/receiving wireless signal in wireless communication system

A device comprising:

• a memory configured to store instructions;
• and
• a processor configured to perform operations by executing the instructions,
• wherein the operations of the processor include:
• receiving a plurality of discontinuous reception (DRX) configurations;
• receiving physical downlink control channel (PDCCH) monitoring adaptation information related to at least one of the plurality of DRX configurations;
• and
• monitoring a PDCCH based on each DRX on-duration of the plurality of DRX configurations and the PDCCH monitoring adaptation information, and
• wherein based on a gap or overlap between a first time period of a first DRX configuration and a second time period of a second DRX configuration among the plurality of DRX configurations, monitoring of a first PDCCH is performed during the first time period and the second time period commonly based on first PDCCH monitoring adaptation information.

A method performed by a base station (BS), the method comprising:

• transmitting a plurality of discontinuous reception (DRX) configurations;
• transmitting physical downlink control channel (PDCCH) monitoring adaptation information related to at least one of the plurality of DRX configurations;
• and
• transmitting a PDCCH based on each DRX on-duration of the plurality of DRX configurations and the PDCCH monitoring adaptation information,
• wherein based on a gap or overlap between a first time period of a first DRX configuration and a second time period of a second DRX configuration among the plurality of DRX configurations, transmission of a first PDCCH is performed during the first time period and the second time period commonly based on first PDCCH monitoring adaptation information.
