Abstract

La présente invention se rapporte à des systèmes et à des techniques se rapportant à des communications sans fil. Une technique décrite consiste à obtenir des données pour une transmission à un ou plusieurs dispositifs de communication sans fil ; inclure une ou plusieurs unités de données de contrôle d'accès (MAC) qui encapsulent les données dans une trame physique (PHY) ; déterminer une longueur d'une plage de contact de couche MAC sur la base d'un certain nombre de symboles associés à la trame PHY ; inclure, en réponse à la longueur de la plage de contact de couche MAC qui est supérieure à zéro, la plage de contact de couche MAC dans la trame PHY après la ou les unités de données MAC ; déterminer une longueur d'une plage de contact de couche MAC sur la base des bits disponibles restants dans la trame PHY ; inclure, en réponse à la longueur de la plage de contact de couche PHY qui est supérieure à zéro, la plage de contact de couche PHY dans la trame après la plage de contact de couche MAC ; et transmettre la trame PHY au dispositif ou aux dispositifs de communication sans fil.
