According to an embodiment of the present invention, a method for managing a network allocation vector (NAV) by a station (STA) in a wireless LAN system supporting a high efficiency physical layer protocol data unit (HE PPDU) comprises the steps of: receiving a frame including an HE-SIG A field and an MAC header; and updating an NAV on the basis of a transmission opportunity duration (TXOP) field included in the HE-SIG A field, wherein, in the step of updating the NAV, the STA may set, for the NAV of the STA, a TXOP duration value indicated by the TXOP duration field when the TXOP duration value indicated by the TXOP duration field is larger than a current NAV value configured by the STA, and the STA may reset the NAV of the STA without comparison with the current NAV value when the TXOP duration field indicates a predetermined value. |
