Abstract
(EN)
According to embodiments, methods, devices and systems can include generating packet data for a narrow band packet. Transmitting first preamble data across a first channel followed by the narrow band packet with a second preamble across at least one resource unit (RU). The RU can have a smaller bandwidth than the first channel and occupy a portion of the first channel. The first preamble can be configured to enable detection of a packet transmitted in the first channel, and the second preamble is configured to enable detection of a packet transmitted in the RU without the first preamble.
(FR)
L'invention concerne, selon certains modes de réalisation, des procédés, des dispositifs et des systèmes pouvant faire intervenir la génération de données de paquet pour un paquet en bande étroite. L'invention comprend également l'émission de premières données de préambule à travers un premier canal, suivies du paquet en bande étroite avec un second préambule à travers au moins une unité de ressources (RU). La RU peut présenter une plus petite largeur de bande que le premier canal et occuper une partie du premier canal. Le premier préambule peut être configuré pour permettre la détection d'un paquet émis dans le premier canal, et le second préambule est configuré pour permettre la détection d'un paquet émis dans la RU sans le premier préambule.
