Method and device for obtaining information about communication entity operating in new band in wireless lan system

A station comprising:

• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• transmitting a probe request frame to a first access point (AP);
• and
• based on the probe request frame, receiving a probe response frame from a first access point (AP) through a 2.4 GHz band or a 5 GHz band, wherein the probe response frame includes a Neighbor Report element related to a second AP operating in a 6 GHz band, and the first AP is in a same co-located AP set as the second AP,
• wherein the Neighbor Report element includes a Basic Service Set Identifier (BSSID) field related to a Basic Service Set (BSS) being reported and a BSSID information field including 1-bit information related to whether the second AP is a High Efficiency (HE) AP,
• wherein the BSSID field has a length of 6 octets and the BSSID information field has a length of 4 octets,
• wherein the Neighbor Report element further includes an HE Basic Service Set (BSS) load element and an HE operation element,
• wherein the HE BSS load element includes information related to utilization, frequency underutilization and spatial stream underutilization,
• wherein the HE operation element includes a 6 GHz Operation Information field providing channel and bandwidth information related to 6 GHz operation,
• wherein the HE operation element further includes an HE Operation Parameters field including a 6 GHz Operation Information Present field, and the 6 GHz Operation Information Present field has a length of 1 bit and is set to one (1) to indicate that the 6 GHz Operation Information field is present.
