摘要： 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.

摘要： Disclosed are a method and a device for recovering an error without the retransmission of a data frame in a wireless LAN. The method for recovering an error in a wireless LAN may comprise the steps in which: a sender STA transmits a data frame to a receiver STA; if the sender STA does not receive a block ACK frame of the data frame from the receiver STA, the sender STA determines the reason for the non-reception of the data frame; if the sender STA determines that the reason for the non-reception of the data frame is the failure of transmission of the block ACK frame after the receiver STA receives the data frame, the sender STA transmits a PBAR data frame to the receiver STA; and the sender STA receives a PBAR block ACK frame from the receiver STA as a response to the PBAR data frame.

摘要： The present document relates to a method for transmitting an acknowledgment/negative-acknowledgment (ACK/NACK) signal for data transmitted from a plurality of stations (STAs) by an access point (AP) in a wireless LAN (WLAN) system and an apparatus therefor. To this end, the AP transmits a trigger frame to the plurality of STAs, receives data transmitted from the plurality of STAs in response to the trigger frame, and transmits and ACK/ANCK signal for the data received from the plurality of STAs. In this process, when all the data received from the plurality of STAs have been successfully received, the ACK/NACK signal may be transmitted not using a block ACK frame but using an ACK frame.

摘要： Disclosed are a method and a device for operation based on a power save mode in a WLAN. The method for operation based on a power save mode may comprise steps in which: an STA, which has been switched to an awake state, transmits a PS-poll frame to an AP on the basis of the transmission cycle of a beacon frame; the STA receives an ACK frame from the AP in response to the PS-poll frame; after receiving the ACK frame, the STA overhears a different BSS frame; and within a preset time upon overhearing the different BSS frame, the STA determines whether or not to maintain the awake state on the basis of whether or not a power management control frame has been transmitted from the AP.
