Abstract:
(EN) A method for sending an uplink frame by a user STA in a wireless LAN system according to an embodiment of the present disclosure comprises the steps of: receiving from an AP a first trigger frame indicating a plurality of first resource units allocated for OFDMA-based random access; performing a first countdown operation on the basis of information set in a backoff counter on the basis of the first trigger frame; upon completion of the first countdown operation, randomly selecting a first random resource unit from among a plurality of resource units and sending a first trigger-based frame corresponding to the first trigger frame through the first random resource unit; receiving a second trigger frame indicating a plurality of second resource units; and if an ACK frame corresponding to the first trigger frame is not received from the AP, performing a second countdown operation on the basis of the second trigger frame.
(FR) La présente invention concerne un procédé destiné à l’envoi d'une trame de liaison montante par un utilisateur de station (STA) dans un système de réseau local (LAN) sans fil selon un mode de réalisation de la présente invention comprend les étapes consistant : à recevoir en provenance d'un point d'accès (AP), une première trame de déclenchement indiquant une pluralité de premières unités de ressources attribuées à un accès aléatoire à base d’accès multiple par répartition orthogonale en fréquence (OFDMA) ; à effectuer une première opération de décompte sur la base d'informations dans un compteur de réduction de puissance sur la base de la première trame de déclenchement ; à l’achèvement de la première opération de décompte, à sélectionner de manière aléatoire une première unité de ressources parmi une pluralité d'unités de ressource et à envoyer un premier signal de déclenchement de trame correspondant à la première trame de déclenchement au moyen de la première unité de ressources aléatoire ; à recevoir une seconde trame de déclenchement indiquant une pluralité de secondes unités de ressource ; et si une trame d’accusé de réception (ACK) correspondant à la première trame de déclenchement n'est pas reçue depuis l'AP, à effectuer une seconde opération de décompte sur la base de la seconde trame de déclenchement.
(KO) 본 명세서의 실시 예에 따른 무선랜 시스템에서 사용자 STA에 의한 상향링크 프레임의 전송을 위한 방법은, OFDMA 기반 랜덤 액세스를 위해 할당된 복수의 제1 자원유닛을 지시하는 제1 트리거 프레임을 AP로부터 수신하는 단계, 제1 트리거 프레임을 기반으로 백오프 카운터에 설정된 정보를 기반으로 제1 카운트다운 동작을 수행하는 단계, 제1 카운트다운 동작을 완료하면 복수의 자원유닛 중 제1 랜덤자원유닛을 임의로 선택하고 제1 트리거 프레임에 상응하는 제1 트리거 기반 프레임을 제1 랜덤자원유닛을 통해 전송하는 단계, 복수의 제2 자원유닛을 지시하는 제2 트리거 프레임을 수신하는 단계 그리고 제1 트리거 프레임에 상응하는 ACK 프레임을 AP로부터 수신하지 못하면 제2 트리거 프레임을 기반으로 제2 카운트다운 동작을 수행하는 단계를 포함한다.
