    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: A method by which an access point (AP) transmits a frame in a wireless LAN, according to one embodiment of the present disclosure, comprises: determining a wake-up radio (WUR) identifier (WID) for identifying a station (STA) and a group identifier (GID) for identifying an STA group to which the STA belongs, in a WUR mode; transmitting the WID and the GID through a primary connectivity radio (PCR) so as to allocate, to the STA, the determined WID and GID; and transmitting, based on the GID or the WID, a WUR frame for waking up a plurality of STAs including the STA operating in the WUR mode, wherein the AP can determine the GID by using a part of an ID space which can be used in the WUR, and determine the WID by using the remaining space excluding the partial ID space used for the GID.

    Abstract: In a wireless local area network (WLAN) system, an STA MLD may include a first STA and a second STA, wherein the first STA operates on a first link, and the second STA operates on a second link. The STA MLD may transmit an association request frame to an access point (AP) MLD. The association request frame may include capability information of a requesting STA, which requests to be associated with the AP MLD, among STAs included in the STA MLD and information related to a request link, to with which a request to be associated is transmitted by the requesting STAs. The STA MLD may receive an association response frame from the AP MLD. The association response frame may include capability information of an AP that operates in a link, an association with which is accepted by the AP MLD, among the request links.

    Abstract: A multi-link device (MLD) in a wireless local area network (WLAN) system is proposed. The MLD may include an access point (AP) MLD. The AP MLD may receive receiving, from a non-simultaneous transmit and receive (Non-STR) station (STA) MLD, a multilink aggregation request signal through a first link. The multilink aggregation request signal may include first information related to a second link for which aggregation is requested and second information related to a transmission opportunity (TXOP) to be set in the second link. The AP MLD may obtain the TXOP based on the second information in the second link. The AP MLD may transmit, to the Non-STR STA MLD, a first multilink aggregation response signal through the first link and a second multilink aggregation response signal through the second link.
