Title (EN) DEMODULATION REFERENCE SIGNAL AND CHANNEL STATE INFORMATION-REFERENCE SIGNAL RESOURCE INDICATION SYSTEM
(FR) SIGNAL DE RÉFÉRENCE DE DÉMODULATION ET SYSTÈME D'INDICATION DE RESSOURCES DE SIGNAL DE RÉFÉRENCE D'INFORMATIONS D'ÉTAT DE CANAL
Abstract:
(EN) Aspects of the present disclosure disclose techniques for the indication of the allocation of the downlink (DL) demodulation reference signal (DM-RS) ports for the data channel in NR communications. In some examples, the channel state information (CSI) reference signal (CSI-RS) may be associated with a corresponding DM-RS for a DL data channel. The transmitting device, in some examples, may further transmit a notification that provides resource allocations (e.g., port allocations) that minimize the redundant information that is required to be transmitted from the base station to the user equipment (UE) when the DM-RS port allocation is the same as the CSI-RS port allocation received by the UE in an earlier time slot.
(FR) Selon certains aspects, la présente invention concerne des techniques pour l'indication de l'attribution des ports de signal de référence de démodulation (DM-RS) de liaison descendante (DL) pour le canal de données dans des communications de nouvelle radio (NR). Selon certains exemples, le signal de référence d'informations d'état de canal (CSI-RS) peut être associé à un signal DM-RS correspondant pour un canal de données de liaison descendante (DL). Selon certains exemples, le dispositif de transmission peut en outre transmettre une notification qui fournit des attributions de ressources (par exemple, des attributions de port) qui minimisent les informations redondantes requises pour être transmises de la station de base à l'équipement utilisateur (UE) lorsque l'attribution de port du signal DM-RS est la même que l'attribution de port de signal CSI-RS reçue par l'équipement utilisateur (UE) dans un intervalle de temps antérieur.
