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.
