Title
(EN) SYSTEM AND METHOD FOR ENHANCEMENTS ON BLOCKWISED DMRS
(FR) SYSTÈME ET PROCÉDÉ D'AMÉLIORATIONS APPORTÉES À UN SIGNAL DE RÉFÉRENCE DE DÉMODULATION (DMRS) À BLOCS
Abstract
(EN)
Systems and methods of using blockwised DMRSs are generally described. A UE uses wideband or blockwised DMRSs as indicated by higher layer signaling or a DMRS scheme indicator of DCI. When transmitting blockwised DMRSs, the blockwised DMRSs have, for different resource blocks or DMRSs, DMRS cyclic shift hopping, different DMRS sequences, different phase rotation, and/or different scrambling sequences. The manner in which the blockwised DMRSs differ depend on the sequences or hopping are cell-specific or UE-specific, as well as whether the multiple symbols in a subframe are allocated to the UE to transmit the DMRSs.

L'invention concerne, en règle générale, des systèmes et des procédés d'utilisation de signaux DMRS à blocs. Un équipement utilisateur (UE) utilise des signaux DMRS à large bande ou à blocs comme indiqué par une signalisation de couche supérieure ou un indicateur de schéma de signal DMRS d'informations de commande de liaison descendante (DCI). Lors de la transmission de signaux DMRS à blocs, les signaux DMRS à blocs ont, pour différents blocs de ressources ou différents signaux DMRS, un saut de décalage cyclique de signal DMRS, différentes séquences de signaux DMRS, une rotation de phase différente et/ou des séquences de brouillage différentes. La manière selon laquelle les signaux DMRS à blocs diffèrent dépend des séquences ou du saut qui sont spécifiques à la cellule ou spécifiques à l'équipement utilisateur, ainsi que de l'attribution, ou non, des multiples symboles dans une sous-trame à l'équipement utilisateur pour transmettre les signaux DMRS.
