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: 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: 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 transmission station (STA) may transmit, to a receiving STA, a PHY protocol data unit (PPDU) including a first redundancy version of transmission data. On the basis of whether an acknowledgement (ACK) or negative ACK (NACK) frame is received within a threshold time, the transmission STA may determine a second redundancy version of the transmission data to be retransmitted.

Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information indicating that a first traffic identifier (TID) is mapped to a first link and a second TID is mapped to a second link. The STA may transmit traffic pertaining to the first TID through only the first link, and traffic pertaining to the second TID through only the second link.

Abstract: Proposed are a method and a device for transmitting an NGV frame in a wireless LAN system. Specifically, a transmission device generates an NGV frame and transmits same via a first band. The NGV frame includes an L-STF, L-LTF, L-SIG, RL-SIG, NGV-SIG, NGV-STF, NGV-LTF and NGV-Data. The NGV-Data includes at least one midamble. The at least one midamble is generated on the basis of a sequence of the NGV-LTF. The sequence of the NGV-LTF includes two time sequences which, in a frequency domain, are mapped to a tone including two tone units, and in a time domain, are repeated in a single OFDM symbol. The at least one midamble includes one or two OFDM symbols.

Abstract: Proposed are a method and a device for requesting the same partial information for all transmission STAs within a transmission MLD and responding thereto in a wireless LAN system. Specifically, a reception MLD transmits an ML probe request frame through a first link from the transmission MLD. The reception MLD receives an ML probe response frame through the first link from the transmission MLD. The ML probe request frame includes a first frame body and a probe request ML element. When the first reception ST A requests the same partial information for all transmission STAs, the first frame body includes a first request element and the probe request ML element does not include a profile sub-element of the second transmission STA.
