Abstract: Proposed are a method and device for performing UL transmission through a multi-link in a wireless LAN system. In detail, a transmission STA generates a first frame including BQR information regarding the multi-link. The transmission STA transmits the first frame to a reception STA. The multi-link is a link in which first and second links are combined with each other. The BQR information regarding the multi-link includes channel state information regarding at least one of the first and second links. The first frame is transmitted through the second link.

Abstract: The present specification proposes a method for resuming a PHY-level HARQ operation in a wireless local area network (WLAN) system. The method may include transmitting a resume signal including information related to resumption of hybrid automatic repeat request (HARQ) retransmission. The method may include transmitting a physical protocol data unit (PPDU) after transmitting the resume signal. The PPDU and the resume signal may be transmitted in different transmission opportunities (TXOPs).

Abstract: One example according to the present specification relates to a method for identifying the format of a PPDU in a wireless LAN (WLAN) system. A receiving STA may receive a first PPDU. The receiving STA may check at least one extra tone of at least one symbol of the first PPDU. The receiving STA may determine, on the basis of the at least one extra tone, the format of the first PPDU as a repeated PPDU format. Thereafter, the receiving STA may receive a second PPDU including the same data as the first PPDU.

Abstract: According to various embodiments, a multi-link device (MLD) operating in a plurality of links may transmit a first request frame for requesting information on the plurality of links. The multi-link device may receive a first response frame on the basis of the first request frame. The first response frame may include information on a ratio of stations (STAs) using a first link as an anchor link, and information on a ratio of STAs using a second link as an anchor 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 sharing access point (AP) may transmit a first selection frame to a first shared AP and transmit a second selection frame to a second shared AP on the basis of information relating to channels between a reception station (STA) and the first shared AP and between the reception STA and the second shared AP. The sharing AP may receive a first selection response frame from the first shared AP. The sharing AP may determine to use the first shared AP in multi-AP transmission on the basis of the first selection response frame.

Abstract: In a wireless local area network system, a reception multi-link device (MLD) may not transmit a CTS frame, even if the reception multi-link device receives an RTS frame via a second link, in the case that an STA operating via a first link is a TXOP responder. In detail, the reception MLD may include at least one non-simultaneous transmit and receive (NSTR) link pair. A first STA affiliated with the MLD may determine to respond with the CTS frame to the RTS frame. The first STA does not respond with the CTS frame based on another STA being a transmission opportunity (TXOP) responder on another link.

Abstract: In a wireless local area network (WLAN) system, a transmission STA can transmit a PPDU via a 320 MHz channel, and a Medium Access Control (MAC) signal may be generated for the PPDU. The MAC signal may include puncturing pattern information and channel center frequency segment (CCFS) information for a 320 MHz band. The CCFS information may include a first CCFS field related to channel center frequency (CCF) information of a primary 160 MHz channel, and a second CCFS field related to CCF information of a 320 MHz channel.
