Abstract[English]
Various aspects of the present disclosure relate to device positioning using distributed antenna coordination. For instance, phase, frequency, and timing synchronization can be implemented between distributed unit (DU) to allow for coherent downlink positioning reference signal (DL PRS) transmission from different DU and enable target user equipment (UE) to efficiently estimate carrier phase. Further, geometry of distributed antennas can allow the resolution of integer ambiguities. Still further, assistance data signalling associated with different distributed antennas can be transmitted.[French]
Divers aspects de la présente divulgation concernent le positionnement d'un dispositif à l'aide d'une coordination d'antennes distribuées. Par exemple, une synchronisation de phase, de fréquence et temporelle peut être mise en oeuvre entre des unités distribuées (DU) pour permettre une transmission de signal de référence de positionnement de liaison descendante (DL PRS) cohérente provenant de différentes DU et permettre à un équipement utilisateur (UE) cible d'estimer efficacement la phase de porteuse. En outre, la géométrie d'antennes distribuées peut permettre la résolution d'ambiguïtés entières. Encore, une signalisation de données d'assistance associée à différentes antennes distribuées peut être transmise.
