The present disclosure relates to measuring a channel based on coordination in a wireless local area network (WLAN), and according to an embodiment of the present disclosure, a method for operating a station (STA) in a WLAN includes: receiving information on a time at which a frame is transmitted from a first access point (AP); receiving a scan response message that is generated based on the information on the time at which the frame is transmitted; receiving the frame from a second AP based on the scan response message; measuring a channel based on the frame received from the second AP; and transmitting a measurement report message to the first AP, wherein the information on the time at which the frame is transmitted includes a time at which the frame is transmitted by at least one AP including the second AP.

In order to perform communication using a subchannel in a wireless LAN system, a method for operating an access point (AP) comprises detecting that a device other than at least one station (STA) associated with the AP is performing communication on a primary channel, obtaining information related to a time duration during which the communication is performed, switching an operating channel from the primary channel to at least one subchannel during the time duration, transmitting or receiving data on the subchannel, and switching the operating channel to the primary channel.
