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: In a wireless local area network, a reception station (STA) may receive, from a transmission STA, a first signal via a first link and a second signal via a second link. The reception STA may transmit, to the transmission STA via the second link, a response signal associated with whether the first and second signals are to be received. The response signal may include a first field associated with the feature of the response signal including responses with respect to whether a plurality of signals transmitted via a plurality of links are to be received.

Abstract: Provided are a method and device for receiving data in a wireless LAN system. Particularly, an STA transmits an operating band negotiation request frame to an AP by means of a first band supported by first and second RFs. The STA receives an operating band negotiation response frame from the AP by means of the first band as a response to the operating band negotiation request frame. The STA changes the first band supported by the second RF into a second band on the basis of the operating band negotiation request frame and the operating band negotiation response frame. The STA receives first data from the AP by means of the first band supported by the first RF and the second band supported by the second RF. The first data is transmitted by means of a multi-band in which the first band and the second band are combined.

Abstract: A method and a device for transmitting data in a wireless LAN system are presented. Particularly, a transmission STA transmits information about a preamble puncturing pattern to a reception STA. The transmission STA transmits data to the reception STA through a 320 MHz band on the basis of the preamble puncturing pattern. The preamble puncturing pattern is determined on the basis of a first bandwidth unit in which a CCA is performed and a second bandwidth unit in which user specific information is repeated. At least one 20 MHz subchannel is punctured in the 320 MHz band on the basis of the preamble puncturing pattern.

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: A method and apparatus for transmitting a PPDU on the basis of S-TDMA in a wireless LAN system are presented. In particular, an AP generates a PPDU, and transmits the PPDU to a first STA and a second STA. When a PPDU further comprises a third signal field, the third signal field comprises information about S-TDMA. The information about S-TDMA comprises STDMA indication information indicating that S-TDMA can be carried out, first symbol offset information about a first data field, and second symbol offset information about a second data field. The S-TDMA indication information comprises information indicating that the first and second data fields are assigned to a first RU. The first data field is transmitted from the first RU during a first symbol determined on the basis of the first symbol offset information. The second data field is transmitted from the first RU during a second symbol determined on the basis of the second symbol offset information.

Abstract: According to various embodiments, a multi-link device (MLD) operating in a plurality of links can receive a PPDU through a first link from among the plurality of links. The PPU can include a first information field related to a second link that is differentiated from the first link. The first information field related to a second link can include a second information field related to a link identifier of a second link and a third information field related to whether all pieces of element information related to a second link is included in the PPDU.
