Abstract: According to various embodiments, a multi-link device including a first STA and a second STA may receive a first PPDU by means of the first STA. The PPDU may include information about traffic buffered in the second STA operating in a second link. In response to the first PPDU, the multi-link device may change the second STA from a doze state to an awake state, and transmit information about the state of the second STA by means of the second STA.

Abstract: Proposed is a method and device for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives the PPDU from a transmitting STA through a broadband and decodes the PPDU. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for the broadband. The first STF sequence is obtained on the basis of a first preamble puncturing pattern of the broadband. When the broadband is a 320 MHz band, the first preamble puncturing pattern includes a pattern in which a 40 MHz or 80 MHz band is punctured in the broadband. The first STF sequence is a sequence including an M sequence and is defined as {M 1 −M 0 −M 1 −M 0 M 1 −M 0 −M 1 −M 0 −M −1 M 0 M −1 M 0 −M −1 M 0 M −1 M}*(1+j)/sqrt(2).

Abstract: In a wireless local area network (LAN) system, an STA of a multi-link device (MLD) may transmit MAC addresses of other STAs included in the same MLD as the STA in a link setup step. The MAC addresses of other STAs may be included multi-link address information. The multi-link address information may be included in a Multi-link Element defined in a conventional Management frame such as a Beacon Frame, a Probe Response Frame, an Association Request Frame, and an Association Response Frame.

Abstract: According to various embodiments, a multi-link device (MLD) operating in a plurality of links including a first link can transmit a request frame to a first AP of an AP MLD through a first STA (station), wherein the request frame includes an information field for requesting every element included in an element set designated for a second link. The MLD can, on the basis of the request frame, receive every element included in the element set designated for the second link.

Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives the PPDU from a transmission STA through a wide band, and decodes the PPDU. The PPDU includes a legacy preamble, and first and second signal fields. The legacy preamble and the first and second signal fields are generated on the basis of a first phase rotation value. When the wide band is the 320 MHz band, the first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1].

Abstract: A transmitting multi-link device (MLD) in a wireless local area network system enables a first station (STA) to perform a back-off operation again without transmitting PPDU, if a second STA is in the middle of receiving even when a back-off counter (BC) of the first STA becomes 0. The first STA and the second STA are included in the same transmitting MLD. The first STA operates on a first link and the second STA operates on a second link. The first and second links are included in a non-simultaneous transmit and receive (NSTR) link pair.

Abstract: In a wireless local area network (LAN) system, a transmitting station (STA) may transmit a peer-to-peer (P2P) transmission request frame to an access point (AP). The transmitting STA may receive a P2P transmission response frame from the AP. The transmitting STA may receive a trigger frame from the AP. The trigger frame may include information related to whether same is for an uplink, P2P transmission or both an uplink and P2P transmission. The transmitting STA may transmit data to a receiving STA. The transmitting STA and the receiving STA may be non-AP STAs. The transmitting STA may transmit a null data packet announcement (NDPA) frame and a null data packet (NDP) frame to the receiving STA. The transmitting STA may receive, from the receiving STA, a feedback frame including state information for the channel between the transmitting STA and the receiving STA.
