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. A method for updating system information in a station (STA) of a wireless communication system, according to one embodiment of the present invention, can comprise the steps of: transmitting, by the STA which stores system information and a configuration change count value of a previously linked preferred access point (AP), a probe request frame for active scanning to the preferred AP; and receiving a probe response frame from the preferred AP. In this situation, the probe request frame includes a configuration change count field previously acquired from the preferred AP, and if a value of the configuration change count field included in the probe request frame is different from a present configuration change count value of the preferred AP, the probe response frame can include one or more elements of system information which should be updated by the STA.

Abstract: A method and apparatus for transmitting frames having a signaling field (SIG) for a second type of station (STA) in a wireless communication system are provided. For this, STA prepares a frame having a first part for a first type of STA and a second part for the second type of STA. Here, the second part includes a first signaling field (HE-SIG A) for common control information and a second signaling field (HE-SIG B) for signaling information comprising user specific control information. Regarding the second signaling field, independent signaling information for the second signaling field (HE-SIG B) is to be transmitted for each 20 MHz bandwidth within a first 40 MHz bandwidth. And the signaling information of the first 40 MHz bandwidth is duplicated in a second 40 MHz bandwidth, when the frame is to be transmitted in a bandwidth equals to or greater than 80 MHz. STA transmits this prepared frame to one or more STAs.

Abstract: The present specification relates to a method of an access point (AP) transmitting a block acknowledgement (ACK) signal with respect to transmission data of a plurality of stations (STA) in a wireless LAN (WLAN) system, and an apparatus therefor. To this end, an AP transmits a multi-STA BA frame with respect to data received from the plurality of STA, wherein the multi-STA BA frame includes a MAC header field, a BA control field and a BA information field. In this regard, the BA information field may include: AID information with respect to one or more STA to which ACK/NACK is transmitted from the plurality of STA; and an individual information field including BA indicator information that indicates whether the BA information field includes one or more of a block ACK bitmap sub-field and a starting sequence control sub-field.

Abstract: The present disclosure relates to a method of receiving, by a station that operates in a wireless LAN system, a signal in a wireless communication system. In this case, it is possible to include the steps of receiving a PPDU that includes an MAC frame, decoding the MAC frame, and checking information in the MAC frame based on the MAC header of the MAC frame that includes a first address field and a second address field. In this case, when the PPDU includes the identification information (ID) of a station, the MAC header may include only one of any of the first address field and the second address field.
