Abstract: In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.

Abstract: A receiving STA of a wireless local area network (LAN) system, according to various embodiments, can support a multi-link including a first link and a second link. The receiving STA can request and receive a link for the transmission of low latency traffic. The receiving STA can transmit the low latency traffic on the basis of a first parameter set through a first link that is set as a link for the transmission of low latency traffic.

Abstract: An embodiment according to the present specification relates to a method for performing low latency communication. An STA can determine a first parameter set between the first parameter set and a second parameter set on the basis of the time delay value of uplink data. The STA can access a channel on the basis of the first parameter set and transmit the uplink data to an AP.

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: 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 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: Provided is a method and device for transceiving a frame in a wireless Local Area Network (LAN) system. Particularly, an Access Point (AP) transmits a first frame to a first station (STA) via a first band. The AP receives a second frame from a second STA via a second band while the first frame is being transmitted. The first band and the second band are combined with each other as a multi-band. The multi-band simultaneously supports a Downlink (DL) transmission and a Uplink (UL) transmission. The relationship between the first STA and the second STA is a hidden node. A Physical (PHY) header of the first frame includes channel status information of the second band. A Network Allocation Vector (NAV) of the first STA is set up on the basis of the channel status information.
