Abstract: Disclosed is a method for a station (STA) to transmit a frame in a wireless communication system. In the present invention, the STA receives a management frame including a first operation element and a second operation element from an access point (AP), and transmits a PPDU to the AP on the basis of the first operation element or the second operation element. Here, the first operation element may indicate a basic service set (BSS) operation channel for a legacy STA, and the second operation element may indicate a BSS operation channel for the STA that is not the legacy STA.

Abstract: Disclosed is a station communicating with a single radio multi-link device, which includes a plurality of stations operating on a plurality of links but does not support simultaneous transmission and reception by the plurality of stations. The station comprises a transmitting/receiving unit and a processor. The processor transmits a control frame to a first station of the single radio multi-link device by using the transmitting/receiving unit, receives a response to the control frame from the first station of the single radio multi-link device, and starts a null data packet (NDP) sounding sequence for the first station of the single radio multi-link device.

Abstract: Disclosed is a method for transmitting and receiving data in a non-access point (AP) multi-link device (MILD) of a wireless communication system. The non-AP MLD may perform a back off procedure for performing simultaneous transmission through a multi-link of the non-AP MLD, and simultaneously perform uplink transmission to an AP MLD through each of a first link and a second link included in the multi-link. Here, when both a first back-off counter and a second back-off counter have a value of “0”, if the transmission time of the uplink transmission in the first link is a slot boundary of a first slot that is a slot next to a slot in which the first back-off counter is “0”, the uplink transmission in the second link may be performed within a predetermined time from the transmission time of the first link.
