Abstract: front page image
(EN)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.
(FR)Selon un mode de réalisation, la présente invention concerne un procédé de gestion d'un vecteur d'attribution de réseau (NAV) par une station (STA) dans un système de réseau local (LAN) sans fil prenant en charge une unité de données de protocole de couche physique à haute efficacité (HE-PPDU), qui comprend les étapes suçivantes : réception d'une trame comprenant un champ HE-SIG A et un en-tête MAC ; et mise à jour d'un NAV sur la base d'un champ de durée d'opportunité d'émission (TXOP) compris dans le champ HE-SIG A. À l'étape de mise à jour du NAV, la STA peut régler, pour le NAV de la STA, une valeur de durée TXOP indiquée par le champ de durée TXOP quand la valeur de durée TXOP indiquée par le champ de durée TXOP est supérieure à une valeur NAV courante configurée par la STA, et la STA peut réinitialiser le NAV de la STA sans comparaison avec la valeur NAV courante quand le champ de durée TXOP indique une valeur prédéterminée.
(KO)본 발명의 일 실시예에 따라서 HE PPDU(high efficiency physical layer protocol data unit)를 지원하는 무선랜 시스템에서 스테이션(STA)이 NAV(network allocation vector)를 관리하는 방법에 있어서, HE-SIG A 필드 및 MAC 헤더를 포함하는 프레임을 수신하는 단계; 및 상기 HE-SIG A 필드에 포함된 TXOP 구간(transmission opportunity duration) 필드에 기초하여 NAV를 업데이트하는 단계를 포함하고, 상기 NAV를 업데이트하는 단계에 있어서, 상기 STA은, 상기 STA에 설정된 현재 NAV 값보다 상기 TXOP 구간 필드에 의해 지시된 TXOP 구간 값이 더 큰 경우에, 상기 TXOP 구간 필드에 의해 지시된 TXOP 구간 값을 상기 STA의 NAV에 설정하되, 상기 TXOP 구간 필드가 소정의 값을 지시하는 경우, 상기 현재 NAV 값과의 비교 없이 상기 STA의 NAV를 리셋 할 수 있다.
