Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information related to low latency traffic. The low latency traffic may be traffic requiring a latency less than or equal to a threshold value. A resource for the low latency traffic may be allocated to the STA. The STA may transmit, via the resource, a second PPDU including the low latency traffic.

Abstract: An example according to the present specification relates to a technique for filtering a PPDU in a wireless LAN (WLAN) system. An STA may receive an NGV PPDU including a first control field and a second control field. The STA may filter the NGV PPDU on the basis of the second control field and may defer channel access on the basis of the first control field.

Abstract: A method for receiving a frame by a station (STA) in a wireless LAN (WLAN) according to the present embodiment: performing a wake-up radio (WUR) negotiation procedure for exchanging WUR operation parameters with an access point (AP) through a primary connectivity radio (PCR); entering a WUR mode; and waking up when a WUR frame is received through a WUR and monitoring a beacon frame through the PCR from the next beacon transmission timing, the WUR operation parameters exchanged through the WUR negotiation procedure include first time information indicating a time for which the STA that has woke up upon reception of the WUR frame needs to monitor the beacon frame from the next beacon transmission timing, and the STA can return to the WUR mode when the beacon frame is not received until the time indicated by the first time information has elapsed.

Abstract: A method for performing, by a station (STA) apparatus, uplink (UL) multi-user (MU) transmission in a wireless communication system according to an embodiment of the present invention includes performing carrier sensing on a channel, receiving a trigger frame including information for UL MU transmission and a carrier sense indicator indicating whether a result of the carrier sensing is to be reflected from an access point (AP), and transmitting an UL MU frame through the channel based on the information for UL MU transmission. The UL MU frame is transmitted through the channel based on a result of the carrier sensing if the carrier sense indicator indicates the reflection of a result of the carrier sensing. The UL MU frame is transmitted through the channel regardless of a result of the carries sensing if the carrier sense indicator does not indicate the reflection of a result of the carrier sensing.

Abstract: A method for performing uplink Orthogonal Frequency Division Multiple Access (UL OFDMA) based random access to an Access Point (AP) by a Station (STA) in a Wireless Local Area Network (WLAN) system is proposed. For the purpose, the STA sets a random value within an OFDMA Contention Window (CWO) as an OFDMA Back-Off (OBO) value, receives a beacon frame from the AP, the beacon frame including transmission start time information of one or more Trigger Frames for Random Access (TF-Rs), decrements the OBO value based on reception of the one or more TF-Rs, and if the OBO value reaches 0, transmits a random access request frame in resources selected randomly from among resources allocated to the STA.
