Abstract: A method and apparatus for scanning a channel in a wireless local area network (WLAN) system may be disclosed including, extracting at least one target channel from among a plurality of channels present in at least one frequency band, based on channel scanning record information, generating a basic service set (BSS) existing information element (IE) including at least one BSS existing channel bitmap indicating information associated with a channel in which at least one access point (AP) exists, based on channel information received from at least one neighboring station (STA), determining a scanning rank of the at least one target channel, using the BSS existing channel IE, and identifying a target AP through scanning the at least one target channel, based on the scanning rank.
