Abstract: In a wireless local area network (WLAN) system, a transmitting STA may transmit wake-up time information related to a receiving STA to the receiving STA. The transmitting STA may transmit a sensing start frame to the receiving STA during a wake-up time. The transmitting STA may transmit a sensing frame to the receiving STA. The transmitting STA may transmit a feedback requesting frame for the sensing frame to the receiving STA. The transmitting STA may receive a feedback frame for the sensing frame from the receiving STA. The wake-up time information may include duration information for maintaining an awake state in which the receiving STA can monitor a signal received from the transmitting STA, and period information for transitioning to the awake state.

Abstract: Provided are a method and apparatus for requesting complete information or partial information on access points (APs) in a transmitting multi-link device (MLD) in a wireless local area network (WLAN) system. 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. The probe request frame includes a profile field of the second receiving STA.

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.
