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.

Abstract: Disclosed is a method for receiving data by a terminal in a wireless communication system. The terminal may receive a physical protocol data unit (physical layer protocol data unit: PPDU) from an access point (APAP) and decode the received PPDU. The PPDU may include a universal signal (U-SIG) field and an extremely high throughput (EHT)-SIG field including at least one content channel, and the U-SIG field may include a bandwidth field indicating the total bandwidth via which the PPDU is transmitted. The total bandwidth is divided into at least one segment, and at least one of field among same fields includes same information except for a resource unit allocation(RU allocation) field between a first content channel and a second content channel in the same segment among the at least one segment when the at least one content channel is composed of a first content channel and a second content channel.

Abstract: A station in a wireless communication system is disclosed. The station includes: a transceiver; and a processor for controlling the transceiver. The processor receives a trigger frame for triggering uplink transmission from an access point (AP), and the trigger frame allocates, to the station, a part of a transmission opportunity (TXOP) acquired by the AP, as a shared TXOP, transmits a CTS frame as a response to the trigger frame, and switches a first enhanced distributed channel access (EDCA) parameter set used for channel access to a second EDCA parameter set based on transmission for the AP within the shared TXOP.

Abstract: Disclosed is a method by which a station (STA) of a multi-link device (MLD) transmits frames in a wireless communication system. In the present invention, an MLD transmits, to an AP MLD including at least one access point (AP), a request message related to a channel access, and receives a response message in response to the request message.

Abstract: Disclosed is a method for receiving a physical layer protocol data unit (PPDU) in a wireless communication system. A terminal receives, from an access point (AP), an extremely high throughput (EHT) PPDU comprising at least one EHT-signal (SIG) content channel. Each of the at least one EHT-SIG content channel comprises a user-specific field and a common field comprising at least one first resource unit (RU) allocation subfield. An STA then identifies whether the common field further comprises at least one second RU allocation subfield, and can decode the PPDU on the basis of whether the common field further comprises the at least one second RU allocation subfield.

Abstract: A multi-link device using a plurality of links is disclosed. A processor receives, in any one link of the plurality of links, a first physical layer protocol data unit (PPDU) including access category (AC) constraint signaling and a reverse direction (RD) grant from a station which is a transmission opportunity (TXOP) holder or a service period (SP) source, and transmits, in the any one link, a second PPDU to the station in response to the first PPDU on the basis of the AC constraint signaling. The AC constraint signaling indicates whether a traffic identifier (TID) or AC of a frame included in the second PPDU is constrained.
