Abstract: Disclosed are a priority-based transmission method and device associated with a target wake time operation in a wireless LAN system. The method for exchanging frames by a station (STA) in a wireless LAN system according to one embodiment of the present disclosure may comprise the steps of: receiving information relating to a restricted target wake time (r-TWT) from an access point (AP); and exchanging frames before the starting point of a service period (SP) of the r-TWT. The information relating to the r-TWT is included in a TWT element comprising a TWT parameter set field format. The TWT parameter set field format comprises a TWT information field. The TWT information field may comprise a TID subfield for traffic associated with the r-TWT.

Abstract: 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.

Abstract: Disclosed are a method and device for reporting a buffer state for latency-sensitive traffic in a wireless LAN system. A method for a station (STA) to transmit a buffer state report (BSR) in a wireless LAN system according to an embodiment of the present invention comprises the steps of: transmitting, to an access point (AP), a frame including a first BSR control subfield including first queue size information about first-type traffic and second-type traffic; and transmitting, to the AP, a frame including a second BSR control subfield including second queue size information about the second-type traffic, wherein the second-type traffic may correspond to latency-sensitive traffic, and the first-type traffic may correspond to traffic other than the second-type traffic.

Abstract: 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.
