    Abstract: Proposed are a method and an apparatus for configuring a space reuse field in a WLAN system. Specifically, a receiving STA receives a trigger frame from a transmitting STA. The receiving STA transmits a TB PPDU to the transmitting STA through a 320 MHz band. The trigger frame includes first and second non-HT Dup PPDUs. In a first non-HT Dup PPDU, all fields are copied and transmitted for each 20 MHz channel over a first 160 MHz channel having a low frequency within a 320 MHz band. In a second non-HT Dup PPDU, all fields are copied and transmitted for each 20 MHz channel over a second 160 MHz channel having a high frequency within the 320 MHz band. The first non-HT Dup PPDU includes a first common information field and a first special user information field. The second non-HT Dup PPDU includes a second common information field and a second special user information field.

    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: Proposed are a method and an apparatus for receiving an MAC address of another STA within a reception MLD in a wireless LAN system. Specifically, the reception MLD receives an ML element from a transmission MLD through a first link. The reception MLD decodes the ML element. The ML element includes common information and link information. The link information includes a profile field of the second transmission STA. The profile field of the second transmission STA includes first information relating to whether an MAC address of the second transmission STA exists. If the first information is configured to be 1, the profile field of the second transmission ST A includes the MAC address of the second transmission STA.

    Abstract: Proposed are a method and device for acquiring critical update information of an AP in a transmitting MLD, on the basis of a TIM frame, in a wireless LAN system. Specifically, a receiving MLD receives a TIM frame from a transmitting MLD through a first link. The receiving MLD decodes the TIM frame. 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. The TIM frame comprises a check beacon field and a MLD change sequence field. The check beacon field comprises critical update information of the first transmitting STA. The MLD change sequence field comprises critical update information of the second and third transmitting STAs.

    Abstract: A transmission STA in a wireless local area network system can transmit a sensing start frame. The sensing start frame can comprise information relating to a feedback method and feedback frequency. The feedback method can comprise information relating to at least one of an explicit feedback, implicit feedback and hybrid feedback. The transmission STA can transmit a sensing frame to a reception STA. The transmission STA can receive from the reception STA a feedback frame comprising channel state information obtained on the basis of the sensing frame. The sensing start frame can further comprise information relating to the number of sensing frame transmissions. The information relating to feedback frequency can comprise information relating to the number of received sensing frames prior to the transmission of the feedback frame by the reception STA.

    Abstract: In a wireless local area network (LAN) system, a transmission MLD may comprise a first station (STA) and a second station (STA), wherein the first STA operates in a first link, and the second STA operates in a second link. The transmission MLD may transmit a connection request frame to a reception MLD. The connection request frame may comprise capability information related to whether a restricted basic service set (BSS) mode is supported and information related to use of the restricted BSS mode. The information related to the use of the restricted BSS mode may comprise first information related to an STA which operates in the restricted BSS mode, among STAs included in the transmission MLD. The restricted BSS mode may mean a mode in which monitoring for signal reception is performed on the basis of acquisition of information, from an STA not operating in the restricted BSS mode, by the STA operating in the restricted BSS, the information indicating reception of a signal. The transmission MLD may receive a connection response frame from the reception MLD.
