Title
(EN) METHOD AND APPARATUS FOR V2X ASSISTED POSITIONING DETERMINATION USING POSITIONING REFERENCE SIGNAL SIGNALS
(FR) PROCÉDÉ ET APPAREIL DE DÉTERMINATION DE POSITIONNEMENT ASSISTÉ PAR V2X EN UTILISANT DES SIGNAUX DE SIGNAL DE RÉFÉRENCE DE POSITIONNEMENT
Abstract
(EN)
A user equipment (UE) may receive Vehicle-to-Everything (V2X) information from a V2X entity, such as a vehicle, road side unit, or other UE carried by a pedestrian. The V2X information may be transmitted to a location server by the UE to obtain positioning assistance data. The location server may determine a coarse position of the UE using the V2X information and generate corresponding positioning assistance data including Positioning Reference Signal (PRS) information for neighbor base stations, which is transmitted to the UE. The UE may detect PRS signals from the neighbor base stations and perform position determination using the PRS signals. The V2X entity or a different V2X entity may also transmit PRS signals that are received by the UE and used along with the PRS signal from the neighbor base stations to perform position determination.
(FR)
L'invention se rapporte à un équipement d'utilisateur (UE) qui peut recevoir des informations de véhicule à environnement (V2X) de la part d'une entité V2X, telle qu'un véhicule, une unité d'infrastructure ou un autre UE transporté par un piéton. Les informations V2X peuvent être transmises à un serveur d'emplacement par l'UE en vue d'obtenir des données d'assistance de positionnement. Le serveur d'emplacement peut déterminer une position grossière de l'UE en utilisant les informations V2X et générer des données d'assistance de positionnement correspondantes qui contiennent des informations de signal de référence de positionnement (PRS) pour des stations de base voisines, qui sont transmises à l'UE. L'UE peut détecter des signaux PRS provenant des stations de base voisines et effectuer une détermination de position en utilisant les signaux PRS. L'entité V2X ou une entité V2X différente peut également transmettre des signaux PRS qui sont reçus par l'UE et utilisés conjointement avec le signal PRS en provenance des stations de base voisines pour effectuer une détermination de position.
