Title (EN) TIME AND FREQUENCY SYNCHRONIZATION
(FR) SYNCHRONISATION TEMPORELLE ET FRÉQUENTIELLE
Abstract: front page image
(EN)The scheduling flexibility of CSI reference signals enables time and frequency synchronization using multiple non-zero CSI-RSs transmitted in the same subframe, or using CSI-RSs transmitted in the same subframe with other synchronization signals. Also, multiple synchronization signals may be scheduled in the same subframe to enable fine time and frequency synchronization without cell-specific reference signals.
(FR)La flexibilité d'ordonnancement de signaux de référence CSI permet de mettre en oeuvre une synchronisation temporelle et fréquentielle au moyen de multiples CSI-RS non nuls transmis dans la même sous-trame, ou au moyen de CSI-RS transmis dans la même sous-trame avec d'autres signaux de synchronisation. De plus, de multiples signaux de synchronisation peuvent être ordonnancés dans la même sous-trame pour permettre une synchronisation temporelle et fréquentielle fine, sans signaux de référence spécifiques de cellule.
