Abstract[English]
Various aspects of the present disclosure relate to configuring demodulation reference signal (DMRS) density. A user equipment (UE) may receive signaling that indicates one or more density values associated with one or more DMRS symbols across a set of resources associated with a physical channel (e.g., a downlink physical channel or an uplink physical channel). The physical channel is associated with a set of layers corresponding to a set of ports of the DMRS symbols. The density values correspond to respective portions of resources of the set of resources occupied by the DMRS symbols. The UE transmits the DMRS symbols via an uplink physical channel or receives the DMRS symbols via a downlink physical channel based on the one or more density values.[French]
Divers aspects de l'invention concernent la configuration de densité de signal de référence de démodulation (DMRS). Un équipement utilisateur (UE) peut recevoir une signalisation indiquant une ou plusieurs valeurs de densité associées à un ou plusieurs symboles DMRS à travers un ensemble de ressources associées à un canal physique (par ex. un canal physique de liaison descendante ou un canal physique de liaison montante). Le canal physique est associé à un ensemble de couches correspondant à un ensemble de ports des symboles DMRS. Les valeurs de densité correspondent à des parties respectives de ressources de l'ensemble de ressources occupées par les symboles DMRS. L'UE transmet les symboles DMRS par un canal physique de liaison montante ou reçoit les symboles DMRS par un canal physique de liaison descendante sur la base des valeurs de densité.
