Method and device for multi-access point operation-based channel allocation in wireless lan system

A first access point (AP) device operating in a wireless local area network (WLAN) system, the device comprising:

• at least one transceiver;
• and
• at least one processor coupled with the at least one transceiver,
• wherein the at least one processor is configured to:
• transmit, through the at least one transceiver, to a second AP, channel-related information of the first AP;
• receive, through the at least one transceiver, from the second AP, resource allocation information related to a multi-access point operation;
• and
• perform, through the at least one transceiver, a frame exchange with at least one station (STA) associated with the first AP on a specific resource based on the resource allocation information.

A second access point (AP) device operating in a wireless local area network (WLAN) system, the device comprising:

• at least one transceiver;
• and
• at least one processor coupled with the at least one transceiver,
• wherein the at least one processor is configured to:
• receive, through the at least one transceiver, channel-related information of an AP group from each AP belonging to the AP group;
• and
• transmit, through the at least one transceiver, resource allocation information for each of at least one AP of the AP group to the each of the at least one AP,
• wherein a specific resource that a frame exchange is performed between at least one station (STA) associated with a first AP of the at least one AP and the first AP is based on resource allocation information transmitted to the first AP.
