A method and a device for transmitting or receiving information related to an access point in a wireless LAN system are disclosed. A method for receiving information related to one or more access points (APs) by a station (STA) in a wireless LAN system according to an embodiment of the present disclosure may comprise the steps of: transmitting a request frame including information indicating one or more of a first AP and a first multi-link device (MLD); and receiving a response frame responding to the request frame from a second AP, wherein the response frame includes a first multi-link (ML) element related to one or more of the first AP and the first MLD, and a second ML element related to one or more of the second AP and a second MLD.

Method and device for transmitting or receiving access point-related information in wireless LAN system

Disclosed are a method and an apparatus for accessing a channel in a wireless LAN system. A method performed by a station (STA) in a wireless LAN system according to an embodiment of the present disclosure may comprise the steps of: receiving information related to a restricted-target wake time (R-TWT) service period (SP) from an access point (AP); and setting at least one R-TWT traffic identifier (TID) for the R-TWT SP. Here, whether to perform a back-off operation for an access category (AC) in the R-TWT SP may be determined on the basis of a mapping relationship between the at least one R-TWT TID and the AC.

Method and apparatus for accessing channel in wireless LAN system

A method and apparatus for communicating in a wireless LAN system are disclosed. The method by which a first station (STA) communicates in a wireless LAN system comprises the steps of: performing, with a second STA, a restricted target wake time (r-TWT) membership setup procedure; and receiving, from the second STA, r-TWT schedule information included in a broadcast TWT element, wherein, on the basis that a specific portion of a first transmission opportunity (TX-OP) in a r-TWT service period (SP) notified by the r-TWT schedule information is not used for downlink (DL) frame transmission corresponding to at least one r-TWT DL traffic identifier (TID) or uplink (UL) frame request corresponding to at least one r-TWT UL TID, the first TXOP may be terminated before the start time of the r-TWT SP.

Restricted target wake time-based method and apparatus for communicating in wireless LAN system

Disclosed are a method and an apparatus for transmitting and receiving protocol data unit (PDU)-related information in a wireless LAN system. The method by which a first station (STA) transmits an aggregate-medium access control (MAC) protocol data unit (PDU) (A-MPDU) in a wireless LAN system, according to an embodiment of the present disclosure, may comprise the steps of: receiving, from a second STA, one or more of first information, second information, and third information related to the maximum length for the A-MPDU; and transmitting, to the second STA, an A-MPDU having a length less than or equal to the maximum length for the A-MPDU, which is derived from a first type physical layer PDU (PPDU) on the basis of the first information, the second information, and the third information.
