Abstract

Un procédé de gestion d'énergie dans un système LAN sans fil selon un mode de réalisation de la présente invention comprend les étapes consistant à : recevoir une trame de balise contenant des informations de fenêtre de contention pour un compteur d'attente d'un accès aléatoire basé OFDMA, et des informations d'instant de début d'une durée de service pour l'accès aléatoire basé OFDMA depuis un point d'accès (AP) par une STA utilisateur ; recevoir, de l'AP, par la STA utilisateur, une trame de déclenchement de référence pour la durée de service sur la base des informations d'instant de début, la trame de déclenchement de référence contenant des informations d'attribution indiquant une pluralité d'unités de ressources et des informations de quantité associées au nombre total d'unités de ressources devant être attribuées pendant la durée de service ; et déterminer l'opportunité d'exécuter une commutation d'un état activé à un état de veille sur la base d'une première valeur d'après les informations de quantité et d'une seconde valeur définie dans le compteur d'attente d'après les informations de fenêtre de contention, par la STA utilisateur.
