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 low-latency traffic, first control information, and second control information. The low-latency traffic may be traffic which requires latency less than or equal to a threshold value. The first control information may include information associated with the size of the low-latency traffic stored in a buffer and the size of other traffic than the low-latency traffic, stored in the buffer. The second control information may include information associated with the low-latency traffic. The STA may be allocated a resource for the low-latency traffic. The STA may transmit a second PPDU through the resource.

Abstract: In a wireless local area network system, a transmitting station (STA) may receive a trigger frame including a user information list. The user information list comprises first and second user information fields, wherein the first user information field includes information related to a first resource unit (RU) for the transmitting STA, and the second user information field may include information related to the second RU for the transmitting STA. The transmitting STA may transmit first data through the first RU and transmit second data through the second RU.

Abstract: Proposed herein is a method and device for receiving a WUR discovery frame in a wireless LAN system. More specifically, a station (STA) receives a WUR discovery element from an access point (AP). The STA receives the WUR discovery frame from a neighbor AP based on the WUR discovery element. The WUR discovery element includes AP list information. The AP list information includes information on a WUR discovery period. The WUR discovery frame is received during the WUR discovery period.

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.
