Specifically, a receiving MLD transmits a probe request frame to the transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The transmitting MLD includes a first transmitting station (STA) operating in the first link and a second transmitting STA operating in a second link. The receiving MLD includes a first receiving STA operating in the first link and a second receiving STA operating in the second link.

Abstract: In a wireless local area network (WLAN) system, an access point (AP) may acquire, from an overlapping Basic Service Set (BSS), information related to a first allocation slot. The first allocation slot may be a time resource allocated for low-latency traffic of the OBSS, and the low-latency traffic may be a new type of traffic whose delay is set below a preconfigured threshold. The AP may transmit, to its associated STA, information related to a second allocation slot. The second allocation slot may be a time resource allocated for low-latency traffic of a BSS to which the AP belongs.

Abstract: A method and an apparatus for transmitting a PPDU in a WLAN system are proposed. Particularly, a transmission device receives configuration information relating to a multi-band. The transmission device performs channel sensing with respect to the multi-band. The transmission device transmits PPDUs to a reception device via the multi-band on the basis of the result of the channel sensing. In the multi-hand, a first band and a second band are combined. The first band includes a first primary channel. The second band includes a second primary channel. The channel sensing is performed on the basis of a first CW value which is set in common for the first and second bands. If transmission of some PPDUs allocated to the second band of the PPDUs fails, the first CW value is increased.

Abstract: One embodiment according to the present specification relates to a technique for transmitting information related to a packet extension field in a wireless LAN (WLAN) system. An NGV PPDU can include at least one midamble and a packet extension field set on the basis of the at least one midamble. For example, a duration related to the packet extension field can be set on the basis of the number of the at least one midamble. A preamble of the NGV PPDU can include information related to a packet extension field.

Abstract: An example according to the present specification relates to a technique for filtering a PPDU in a wireless LAN (WLAN) system. An STA may receive an NGV PPDU including a first control field and a second control field. The STA may filter the NGV PPDU on the basis of the second control field and may defer channel access on the basis of the first control field.

Abstract: A method and a device for transmitting updated information for an ML reconfiguration in a wireless LAN system are proposed. Specifically, a reception MLD performs an ML reconfiguration with a transmission MLD. The reception MLD transmits MLD capability information for the ML reconfiguration to the transmission MLD. The transmission MLD comprises a first transmission STA operating in a first link and a second transmission STA operating in a second link. The reception MLD comprises a first reception STA operating in the first link and a second reception STA operating in the second link. The MLD capability information includes information on a change in the number of links supported by the transmission and reception MLDs at the same time.

Abstract: One embodiment according to the present specification relates to a technique for multiple frame transmission in a wireless LAN (WLAN) system. A transmission STA can transmit a first next generation V2X physical protocol data unit (NGV PPDU) from among a plurality of NGV PPDUs for a multiple frame transmission mode. Afterwards, the transmission STA can identify a channel state for the transmission of a second NGV PPDU from among the plurality of NGV PPDUs. The transmission STA can determine, on the basis of the channel state, whether to transmit the second NGV PPDU.

Abstract: In a wireless local area network system, a station (STA) generates a physical (PHY) protocol data unit (PPDU) including at least one subframe and information related to a subframe length, wherein the subframe may include a medium access control (MAC) protocol data unit (MPDU) and a padding bit. The length of the padding bit may be determined such that the length of the subframes is an integer multiple of a codeword length. The information related to the subframe length may be information on the number of codewords related to the subframe length. A step in which the STA transmits the PPDU may be comprised.
