Abstract

Les modes de réalisation de la présente divulgation concernent un procédé de communication, un dispositif de point d'accès (AP), un dispositif de station et un dispositif de communication. Le procédé de communication comprend les étapes suivantes : un dispositif de point d'accès envoie une première trame radio sur un canal principal, la première trame radio demandant à un dispositif de station d'envoyer une trame de données ou des informations de mémoire cache ; et si une seconde trame radio qui a été envoyée en réponse au dispositif de station n'est pas reçue dans un premier intervalle de trame prédéfini, ne pas envoyer de manière répétée la première trame radio. Ainsi, le gaspillage de ressources de signalisation provoqué par l'envoi répété est évité. De plus, un mécanisme pour qu'un dispositif WLAN effectue une communication dans un canal auxiliaire est mis au point, de telle sorte que le débit d'un système de communication est augmenté, ce qui permet de réaliser l'utilisation maximale de ressources de canal.
