Abstract
La présente invention concerne un élément de réseau doté d'un processeur. Le processeur est configuré pour favoriser l'émission d'une première paire de blocs de ressources physiques (PRB) contenant une première séquence de signal de référence de démodulation (DMRS). Le processeur est en outre configuré pour favoriser l'émission d'une deuxième paire de PRB contenant une deuxième séquence de DMRS. La première séquence de DMRS est un sous-ensemble de la deuxième séquence de DMRS.
