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: A method for transmitting a TB PPDU in a wireless communication system is disclosed. A Non-AP STA can receive a frame for triggering the transmission of a physical layer protocol data unit (PPDU) from an access point (AP), and transmit, in response to the frame, the PPDU including a packet extension (PE) field for providing a processing time for the PPDU. At this time, the frame indicates a format for the PPDU transmitted in response to the frame, and a maximum value of duration for the PE field can be changed according to the format of the PPDU indicated by the frame.

Abstract: A station of a multi-link device is disclosed. The station of the multi-link device comprises a transmission/reception unit and a processor. The multi-link device operates in a first link and a second link, which are non-simultaneous transmit and receive (STR) links in which simultaneous performance of reception by the multi-link device in any one link and the transmission by the multi-link device in another link is not supported. The processor determines that the transmission by another station of the multi-link device in the first link is performed, and if all of one or more predetermined conditions are not satisfied in the second link, the processor performs channel access according to channel access restrictions during the predetermined time from the time when the transmission by the other station in the first link is completed. The channel access restrictions determine whether a wireless medium is valid by using determination conditions.

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 wireless communication terminal wirelessly communicating with a base wireless communication terminal. The wireless communication terminal comprises: a transceiver; and a processor. The processor transmits low latency traffic configured as traffic for low latency transmission in a limited service period, or a response to the low latency traffic, and in the limited service period, transmission except for the transmission of the low latency traffic and the transmission of the response to the low latency traffic is limited.

Abstract: Disclosed is a method for transmitting a frame of a wireless communication system. A non-AP STA receives a beacon frame comprising a request type field from an AP and can receive a downlink frame or transmit an uplink frame in accordance with a specific field value included in the beacon frame. Here, the request type field comprises a specific field for indicating a target wake time (TWT) for a low latency operation, and, if the value of the specific field is set as a first specific value, a broadcast TWT service period (SP) is a TWT SP for the low latency operation.

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 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.
