Abstract[English]
Embodiments of the invention relate to a transmitter device (100) in a communication system (500) for multi-modal concurrent transmission of a first data stream and a second data stream to a receiver device (300). The transmitter device (100) modulates and codes the first data stream and the second data stream separately to obtain first coded and modulated symbols and second coded and modulated symbols, respectively, which are then mapped onto common time-and frequency resources to obtain jointly mapped coded and modulated symbols. The common time-and frequency resources are arranged in spatial layers, each spatial layer being associated with a signal-to-noise ratio (SNR) value and at least two spatial layers are associated with different SNR values. The transmitter device (100) transmits the jointly mapped coded and modulated symbols to the receiver device (300). Furthermore, embodiments of the invention also relate to the receiver device (300), corresponding methods and a computer program.[French]
Des modes de réalisation de l'invention concernent un dispositif émetteur (100) dans un système de communication (500) pour une transmission simultanée multimodale d'un premier flux de données et d'un second flux de données à un dispositif récepteur (300). Le dispositif émetteur (100) module et code le premier flux de données et le second flux de données séparément pour obtenir, respectivement, des premiers symboles codés et modulés et des seconds symboles codés et modulés qui sont ensuite mappés sur des ressources temps et fréquence communes pour obtenir des symboles codés et modulés mappés conjointement. Les ressources temps et fréquence communes sont agencées en couches spatiales, chaque couche spatiale étant associée à une valeur de rapport signal sur bruit (SNR) et au moins deux couches spatiales sont associées à différentes valeurs de SNR. Le dispositif émetteur (100) transmet les symboles codés et modulés mappés conjointement au dispositif récepteur (300). En outre, des modes de réalisation de l'invention concernent également le dispositif récepteur (300), des procédés et un programme informatique correspondants.
