Title (EN) INTERFERENCE SUPPRESSION DURING DEVICE-TO-DEVICE COMMUNICATIONS
(FR) SUPPRESSION D'INTERFÉRENCE PENDANT DES COMMUNICATIONS DE DISPOSITIF À DISPOSITIF
Abstract:
(EN) A method is disclosed that includes selecting one or more terminals involved in a device-to- device communication to which interference caused by a transmission to one or more other terminals should be suppressed, and choosing a number of degrees of freedom from a predetermined number of degrees of freedom to be used to suppress interference towards the selected one or more terminals. The method also includes using the remaining degrees of freedom from the predetermined number to increase signal quality to the one or more other terminals and performing precoding based on the chosen number of degrees of freedom and the remaining degrees of freedom. The method further includes, using at least the performed precoding, transmitting information to the one or more other terminals. Apparatus and programs/program products are also disclosed.
(FR) L'invention concerne un procédé qui consiste à sélectionner un ou plusieurs terminaux impliqués dans une communication de dispositif à dispositif dans laquelle une interférence provoquée par une transmission vers un ou plusieurs autres terminaux devrait être supprimée, et choisir un certain nombre de degrés de liberté parmi un nombre prédéterminé de degrés de liberté à utiliser pour supprimer l'interférence vers le ou les terminaux sélectionnés. Le procédé consiste également à utiliser les degrés restants de liberté du nombre prédéterminé pour augmenter la qualité de signal pour le ou les autres terminaux et à appliquer un précodage sur la base du nombre choisi de degrés de liberté et des degrés restants de liberté. Le procédé consiste en outre, en utilisant au moins le précodage effectué, à transmettre des informations à l'autre terminal ou aux autres terminaux. L'invention concerne également un appareil et des programmes/produits-programmes.
