Title (EN) METHOD FOR TRANSMITTING DATA BY A WIRELESS NETWORK UNIT AND UNIT
(FR) PROCEDE D'EMISSION DE DONNEES PAR UNE ENTITE D'UN RESEAU SANS FIL ET ENTITE
Abstract:
(EN) The invention relates to the transmission of blocks of data, transmitted via a common radio channel between units of a wireless network. The blocks of data (TR PHY) transmitted by a unit are preceded by a header (HEA) and a preamble (PRE) designed to be used by a physical layer. The preamble (PRE) contains information for synchronising a receiver unit for the block and estimating the broadcast channel as well as identification information (ID) of the block transmitting device.
(FR) La présente invention se rapporte à un procédé d'émission de trames de données, transmises par un canal radio commun entre entités d'un réseau sans fil. Les trames de données (TR PHY) émises par une entité sont précédées d'un en-tête (HEA) et d'un préambule (PRE) destinés à être exploités par une couche physique. Le préambule (PRE) contient des informations pour synchroniser une entité réceptrice de la trame et pour estimer le canal de propagation ainsi qu'une information d'identification (ID) de l'entité émettrice de la trame.
