METHOD AND DEVICE FOR FAST LINK SYNCHRONIZATION IN WLAN SYSTEM

摘要

The present invention relates to a wireless communication system, and more specifically, a method and a device whereby a station (STA) performs link setup with an access point (AP) in a WLAN system are disclosed. The method according to one embodiment of the present invention comprises: a step in which an STA receives a first frame related to link setup from an AP in a wireless communication system; and a step in which a second frame related to association is transmitted to the AP, wherein the first frame is a fast initial link setup (FILS) discovery frame and the second frame may comprise timestamp request information in case an AP configuration change count (CCC) value the STA has and an AP CCC value included in the received first frame are determined to be the same.
