Abstract

L'invention concerne un procédé et un appareil d'activation de station pour dispositif à liaisons multiples et un support. Le procédé consiste : en réponse à la présence d'au moins une liaison active avec un dispositif à liaisons multiples (MLD) de station (STA), à générer une trame de message ; à transmettre la trame de message au moyen de la liaison active, la trame de message comprenant un champ d'activation pour activer au moins une station dans un état d'économie d'énergie dans le MLD de STA. Dans les modes de réalisation de la présente invention, lorsqu'une liaison active est établie entre un MLD d'AP et un MLD de STA, une trame de message comprenant un champ d'activation est générée, le champ d'activation étant utilisé pour activer au moins une STA dans un état d'économie d'énergie dans le MLD de STA. Le MLD d'AP transmet la trame de message au moyen de la liaison active, et une STA à activer est explicitement indiquée au MLD de STA, de telle sorte que le MLD d'AP peut commander de manière précise et efficace l'activation d'une ou d'au moins deux stations dans le MLD de STA, ce qui permet d'obtenir une nouvelle solution pour un mécanisme d'activation entre le MLD d'AP et le MLD de STA, de façon à améliorer l'efficacité de gestion de liaison.
