Abstract: The present invention relates 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 may comprise 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. Preferably, 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 may include one or more elements of system information which should be updated by the STA.

Abstract: Proposed are a method and device for acquiring information on links between MLDs in a wireless LAN system. Specifically, a receiving MLD transmits a probe request frame to a transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The transmitting MLD comprises: a first transmitting STA operating in the first link; a second transmitting STA operating in a second link; and a third transmitting STA operating in a third link. The receiving MLD comprises a first receiving STA operating in the first link. When the first receiving STA requests for information on the second and third links, the probe request frame includes link identifiers for the second and third links. When the first receiving STA requests for information on all the links, the probe request frame does not include link identifiers for all the links.

Abstract: A method and apparatus for identifying change sequence information in a wireless LAN system are proposed. In detail, an STA receives a DTIM beacon frame and a beacon frame from a first AP. The STA decodes the DTIM beacon frame in a first awake state and decodes the beacon frame in a second awake state. Both the DTIM beacon frame and the beacon frame include a CUF and a CSN. When a significant update of a second AP occurs, a value of the CUF is changed from 0 to 1 until transmission of a next DTIM beacon frame, the value of the CUF is changed from 1 to 0 after the transmission of the next DTIM beacon frame, and the CSN includes updated information. The updated information is decoded in the second awake state regardless of the value of the CUF.

Abstract: The present specification proposes a new procedure of signal transmission or reception between STAs in a case of sensing measurement initiated by an STA rather than an AP. According to an embodiment of the present specification, proposed is a sensing measurement procedure performed by an AP in response to transmission of a sensing initiation frame to the AP by an STA rather than the AP. According to another embodiment of the present specification, according to an embodiment of the present specification, proposed is a procedure in which an STA rather than an AP transmits a sensing initiation frame to the AP, and then the AP requests respondent STAs to transmit NDP frames. According to yet another embodiment of the present specification, proposed is a method for configuring a frame transmitted or received in the above procedures.

Abstract: The specification proposes a method for requesting information on a restricted TWT when an STA has failed to receive the information. According to an embodiment of the present specification, when an STA fails to acquire information on a restricted TWT, the STA may transmit, to an AP, a signal for requesting the information on the restricted TWT after a certain time elapses from a TBTT. The signal may be transmitted independently or may be transmitted together with another signal transmitted by the STA.
