Abstract: In a wireless local area network (WLAN) system, a first station (STA) may transmit first information related to a maximum value of a hybrid automatic repeat request (HARQ) index supported by the first STA, and second information related to a time limit related to the HARQ index. The HARQ index may be used for an HARQ operation of the first STA, and the time limit may be used for a maximum storage time of an HARQ buffer related to the HARQ index. The first STA may perform an association with a second STA on the basis of the first information and the second information.

Abstract: One embodiment according to the present specification relates to a method for transmitting, from a first link, information for setting a NAV in a second link. When transmission STA performs communication through a second link, the transmission STA can transmit, through a first link, information for setting the NAV for the second link in another STA. Particularly, the transmission STA can receive, from the second reception STA, a second frame through the second link. The transmission STA can transmit, to a first reception STA, a first frame through the first link during the reception of the second frame. The first frame can include information for setting the NAV for the second link. The first reception STA can set the NAV for the second link on the basis of the first frame.

Abstract: The present document relates to a method and device for an Access Point (AP) to transmit ACK/NACK signals for MU (Multi-User) transmission data of a plurality of stations (STA) in a wireless LAN (WLAN) system. To this end, the method and device are characterized in that a STA responds to a trigger frame received from an AP, transmits data to the AP through an MU access technique, and sets an ACK policy value for data transmitted on the basis of the trigger frame to another value other than a first ACK policy value requesting an ACK signal transmission on the basis of a block ACK request.

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: A method and device for transmitting data in a wireless LAN system are provided. 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 data to a reception device via the multi-band on the basis of the result of the channel sensing. A first band and a second band are combined in the multi-band. The first band comprises a first primary channel, and the second band comprises a second primary channel. The result of the channel sensing is obtained on the basis of whether or not the first primary channel is idle until a first BC value becomes 0 and whether or not the second primary channel is idle until a second BC value becomes 0. The first BC value is selected within a first CW configured with respect to the first primary channel. The second BC value is selected within a second CW configured with respect to the second primary channel.

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.
