Method and apparatus for updating system information in wireless LAN system

摘要

The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for updating system information in a wireless LAN system. A method for a station (STA) to update system information in a wireless communication system according to one embodiment of the present invention comprises the steps of: if the value of a change sequence field received by the STA from an access point (AP) is different from the value of the change sequence field stored in the STA, transmitting, to the AP, a probe request frame including the change sequence field set to the value of the change sequence field stored in the STA; and a step of receiving, from the AP, a probe response frame responding to the probe request frame including the change sequence field.

主权项

1. A method for updating system information by a station (STA) of a wireless communication system, the method comprising:
receiving, by the STA, a beacon frame comprising a first change sequence field set to a first value from an access point(AP); transmitting a probe request frame comprising a second change sequence field set to a second value stored in the STA, to the AP, when the first value is different from the second value; and receiving a probe response frame comprising at least one of a plurality of system information elements, wherein the at least one system information element needs to be updated by the STA, in response to the probe request frame from the AP.
