Abstract

Divers aspects de la présente divulgation concernent une commande pour un système de l'internet des objets ambiant (A-IoT). Selon un aspect, un premier dispositif (par exemple, une station de base (BS)) détermine une ou plusieurs premières configurations d'une ou plusieurs commandes et/ou une seconde configuration d'une ou de plusieurs fenêtres de transmission associées à la ou aux commandes. De plus, le premier dispositif transmet, à un second dispositif (par exemple, un dispositif A-IoT), une ou plusieurs configurations parmi la première configuration ou la seconde configuration. Le second dispositif surveille au moins une commande de la ou des commandes sur la base d'une ou plusieurs configurations parmi la première configuration ou la seconde configuration. De cette manière, il est possible d'améliorer la flexibilité et l'efficacité de communication de paramètre déclenchée par commande depuis le second dispositif.
