Abstract: A multi-link device (MLD) in a wireless local area network (WLAN) system is proposed. The MLD may include an access point (AP) MLD. The AP MLD may receive receiving, from a non-simultaneous transmit and receive (Non-STR) station (STA) MLD, a multilink aggregation request signal through a first link. The multilink aggregation request signal may include first information related to a second link for which aggregation is requested and second information related to a transmission opportunity (TXOP) to be set in the second link. The AP MLD may obtain the TXOP based on the second information in the second link. The AP MLD may transmit, to the Non-STR STA MLD, a first multilink aggregation response signal through the first link and a second multilink aggregation response signal through the second link.

Abstract: In a wireless local area network (LAN) system, an STA of a multi-link device (MLD) may transmit MAC addresses of other STAs included in the same MLD as the STA in a link setup step. The MAC addresses of other STAs may be included multi-link address information. The multi-link address information may be included in a Multi-link Element defined in a conventional Management frame such as a Beacon Frame, a Probe Response Frame, an Association Request Frame, and an Association Response Frame.

Abstract: According to various embodiments, a multi-link device (MLD) operating in a plurality of links may receive information regarding a plurality of groups into which the plurality of links are classified. The information regarding the plurality of groups may include information regarding IDs allocated to the plurality of groups and information regarding power saving (PS) intervals allocated to the plurality of groups. The multi-link device may change, on the basis of the information regarding the plurality of groups, at least one STA included in the multi-link device to be in a doze state.

Abstract: In a wireless local area network system, a receiving device may receive a Block Acknowledgment Request (BAR) frame including information related to a link for which an ACK is requested, and transmit a Block ACK (BA) frame on the basis of the BAR frame. The receiving device is a Multi-Link Device (MLD), which supports communication over multiple links. Each link of the multiple links can be configured based on 2.4 GHz band, 5 GHz band, and/or 6 GHz band defined in a conventional wireless local area network system.

Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information indicating that a first traffic identifier (TID) is mapped to a first link and a second TID is mapped to a second link. The STA may transmit traffic pertaining to the first TID through only the first link, and traffic pertaining to the second TID through only the second link.

Abstract: One example according to the present specification relates to a method for identifying the format of a PPDU in a wireless LAN (WLAN) system. A receiving STA may receive a first PPDU. The receiving STA may check at least one extra tone of at least one symbol of the first PPDU. The receiving STA may determine, on the basis of the at least one extra tone, the format of the first PPDU as a repeated PPDU format. Thereafter, the receiving STA may receive a second PPDU including the same data as the first PPDU.

Abstract: Provided are a method and apparatus for receiving only complete information on other access points (APs) in a transmitting multi-link device (MLD) in a wireless local area network (WLAN) system. Specifically, a receiving MLD transmits a probe request frame to the transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The probe request frame includes a frame body and a profile field of a second receiving station (STA). When a first receiving STA does not request complete information on the first link and requests complete information on the second link, the complete information on the second link is requested based on the profile field of the second receiving STA. The probe response frame does not include the complete information on the first link, and includes only the complete information on the second link.

Abstract: Provided is a method and device for transceiving a frame in a wireless LAN system. Particularly, an AP transmits a first frame to a first STA via a first band. The AP receives a second frame from a second STA via a second band while the first frame is being transmitted. The first band and the second band are combined with each other as a multi-band. The multi-band simultaneously supports a DL transmission and a UL transmission. The relationship between the first STA and the second STA is a hidden node. A PHY header of the first frame includes channel status information of the second band. An NAV of the first STA is set up on the basis of the channel status information.
