Summary:A method by which a first wireless terminal transmits an uplink frame in a wireless LAN system comprises the steps of: receiving a first trigger frame for OFDMA-based random access from a second wireless terminal; receiving, from the second wireless terminal, a second trigger frame for OFDMA-based random access without transmitting a trigger-based uplink frame, if a first transmission size of a first random resource unit is smaller than a traffic size for the transmission of the trigger-based uplink frame; and transmitting the trigger-based uplink frame to a second random resource unit. L'invention concerne un procédé par lequel un premier terminal sans fil transmet une trame de liaison montante dans un système LAN sans fil, qui comprend les étapes consistant à : recevoir, en provenance d'un second terminal sans fil, une première trame de déclencheur pour un accès aléatoire basé sur OFDMA ; recevoir, en provenance du second terminal sans fil, une seconde trame de déclencheur pour un accès aléatoire basé sur OFDMA sans transmettre une trame de liaison montante basée sur un déclencheur si une première taille de transmission d'une première unité de ressource aléatoire est plus petite qu'une taille de trafic pour la transmission de la trame de liaison montante basée sur le déclencheur ; et transmettre la trame de liaison montante basée sur le déclencheur à une seconde unité de ressource aléatoire. 제1 무선 단말에 의해 수행되는 무선랜 시스템에서 상향링크 프레임의 송신을 위한 방법은 OFDMA 기반 랜덤 액세스를 위한 제1 트리거 프레임을 제2 무선 단말로부터 수신하고, 제1 랜덤자원유닛의 제1 전송 사이즈가 트리거 기반 상향링크 프레임의 전송을 위한 트래픽 사이즈보다 작다면, 트리거 기반 상향링크 프레임의 전송 없이 OFDMA 기반 랜덤 액세스를 위한 제2 트리거 프레임을 제2 무선 단말로부터 수신하고, 제2 랜덤자원유닛으로 트리거 기반 상향링크 프레임을 전송하는 단계를 포함한다.
