Abstract:
The present invention relates to a wireless communication system and, more specifically, to a method and a device for updating system information in a wireless LAN system. The method for updating system information in a station (STA) of a wireless communication system, according to one embodiment of the present invention, comprises the steps of: allowing the STA to transmit, to an access point (AP), a probe request frame that includes a change sequence field which is set to a value of a change sequence field stored in the STA, if a value of a change sequence field received from the AP is different from the value of the change sequence field stored in the STA; and allowing the STA to receive, from the AP, a probe response frame which responds to the probe request frame that includes the change sequence field, wherein the probe request frame can be a short probe request frame.
