Abstract: Disclosed is a method by which a station (STA) transmits a frame in a wireless communication system. The STA according to the present invention receives, from an access point (AP), a trigger frame indicating uplink transmission, and transmits a physical layer protocol data unit (PPDU) to the AP and/or another STA within a shared transmission opportunity (TXOP), on the basis of the trigger frame. Here, the trigger frame is used to share, with the STA, a part or all of the TXOP obtained by the AP. Also, the PPDU includes duration information indicating the TXOP for transmission of the PPDU, and the duration information is configured on the basis of the shared TXOP.

Abstract: Disclosed is a multi-link device which includes a plurality of stations respectively operating in a plurality of links, but which, in an enhanced multi-link single radio (EMLSR) mode, does not perform transmission and reception in a second link of an EMLSR link while performing frame exchange in a first link of the EMLSR link, wherein the EMLSR link is a plurality of links to which the EMLSR mode is applied. The multi-link device comprises a transmission and reception unit, and a processor. When in the EMLSR mode, a first station, which is one of the plurality of stations included in the multi-link device, performs the frame exchange as a transmission opportunity (TXOP) holder in the first link, the processor ends the TXOP for the frame exchange before a point in time that arrives a predetermined time earlier than the point in time at which the multi-link device is to receive a beacon frame. The predetermined time is a delay time for the multi-link device to perform link switching.

Abstract: Disclosed are a method and a device for transmitting or receiving a frame performed by a first multi-link device (MLD) including a first plurality of stations in a wireless communication system. Specifically, a non-AP MLD according to the present disclosure may perform a multi-link configuration procedure for setting up at least one link with an AP MLD including a plurality of APs, and change an operating channel from a first channel to a second channel in a first link with a first AP among the plurality of APs. In this case, the second channel is one of at least one channel excluding a channel which overlaps one or more operating channels for one or more other non-AP MLDs combined with the AP MLD.

Abstract: Disclosed are a traffic transmission method and device, the method being performed by a terminal in a wireless communication system. Specifically, a non-access point (AP) STA of the present invention can receive, from an AP, a trigger frame triggering the transmission of a physical layer protocol data unit (PPDU). The trigger frame includes information indicating at least one traffic identifier (TID) that is allowed to be transmitted in a target wake time (TWT) period. The TWT period may indicate a period in which the transmission of traffic for the at least one TID having a specific transmission condition is allowed, and the transmission of traffic not having the specific transmission condition is restricted. Thereafter, the non-AP STA transmits a PPDU, including the traffic corresponding to the at least one TID, to the AP within the TWT period.

Abstract: Disclosed is a multi-link device comprising multiple stations operating in multiple links, respectively. The multi-link operation device comprises: a transceiver; and a processor. The processor transmits a target wake time (TWT) element from a first station which is one of the multiple stations and is coupled to a first AP in a first link, so as to request a TWT agreement with a second station operating in a second link, for a second AP coupled to the second station.

Abstract: Disclosed is a method for transmitting or receiving a physical layer protocol data unit (PPDU) in a wireless communication system. A terminal receives, from an access point (AP), a frame indicating, to one or more terminals, transmission of the PPDU. The frame comprises a common information field and a user information field for each of the one or more terminals, and at least one of the common information field and the user information field is used to identify whether the PPDU indicated by a trigger frame corresponds to an extremely high throughput (EHT) PPDU or a high efficiency (HE) PPDU. In response to the frame, the terminal transmits the PPDU.

Abstract: Disclosed is a method for transmitting and receiving a PPDU in a wireless communication system. A terminal receives, from an access point (AP), a frame indicating transmission of a PPDU to one or more terminals and transmits the PPDU on the basis of an AID12 subfield included in the frame. In this case, if the PPDU indicated to be transmitted by the frame is an extremely high throughput (EHT) PPDU, a value of the AID12 subfield is configured to one of multiple values excluding at least one specific value, and the at least one specific value is used to allocate a resource for an uplink orthogonal frequency division multiple access (OFDMA)-based random access (UORA) of at least one terminal supporting high efficiency (HE).

Abstract: An AP multi-link device is disclosed. The AP multi-link device comprises: a transceiver; and a processor. During reception at any one link, when performing transmission at the second link to a non-AP multi-link device operating at a first link and a second link, which are non-simultaneous transmit and receive (STR) links not supported for transmission at another link, the processor determines whether to perform transmission at the second link for the non-AP multi-link device based on whether the non-AP multi-link device is transmitting to the first link.
