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.

Abstract: A method for performing network allocation vector (NAV) operation by a station (STA) in a wireless LAN system, according to an embodiment of the present invention, comprises the steps of: receiving a first frame; and configuring NAV in accordance with basic service set (BSS) of the first frame, wherein the first frame is other BSS (OBSS) frame. If a received signal strength indicator (RSSI) is lower the OBSS packet detection (PD) level, an STA drops the OBSS frame without configuration of the NAV. And if second frame transmission of another STA following the OBSS frame is scheduled, the STA can defer the OBSS frame drop even if the RSSI is lower than the OBSS PD level.
