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: 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: 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: Proposed are a method and an apparatus for changing a primary link belonging to an NSTR link pair through an ML element in a WLAN system Specifically, a receiving MLD receives an ML element from a transmitting MLD via a first link. The receiving MLD decodes the ML element. The first link is a primary link, and a second link is a non-primary link. The first and second links are link pairs operating as NSTRs. The ML element contains a common information field. The common information field includes first and second subfields. The first subfield includes information that the primary link is changed from the first link to the second link. The second subfield includes information on a time when the primary link is changed from the first link to the second link.

Abstract: Proposed are a method and an apparatus for transferring information requested by a non-AP STA for P2P transmission to an AP in a wireless LAN system. Specifically, a first receiving STA receives a QoS data frame or a QoS null frame from a transmitting STA. The first receiving STA receives a MU-RTS TXS frame from the transmitting STA. The first receiving STA transmits data to a second receiving STA on the basis of the MU-RTS TXS frame. The QoS data frame or the QoS null frame includes a TXS control frame. The TXS control frame includes first information on a time required for transmission of the data and second information on a bandwidth required for the transmission of the data. The MU-RTS TXS frame includes third information on a time allocated for transmitting the data and fourth information on a bandwidth allocated for transmitting the data.

Abstract: Proposed are a method and device for acquiring information on links between MLDs in a wireless LAN system. Specifically, a receiving MLD transmits a probe request frame to a transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The transmitting MLD comprises: a first transmitting STA operating in the first link; a second transmitting STA operating in a second link; and a third transmitting STA operating in a third link. The receiving MLD comprises a first receiving STA operating in the first link. When the first receiving STA requests for information on the second and third links, the probe request frame includes link identifiers for the second and third links. When the first receiving STA requests for information on all the links, the probe request frame does not include link identifiers for all the links.
