NAV OPERATION METHOD IN WIRELESS LAN SYSTEM AND STATION APPARATUS FOR SAME

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 than 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.
