Title
(EN) POSITIONING BASED ON RELATIVE POSITIONS OF BASE STATIONS AND/OR USER EQUIPMENTS
(FR) POSITIONNEMENT BASÉ SUR DES POSITIONS RELATIVES DE STATIONS DE BASE ET/OU D'ÉQUIPEMENTS UTILISATEURS
Abstract
(EN) A user equipment (UE) receives assistance data for positioning that includes relative position information for anchor points, such as base stations and/or sidelink UEs. The relative position information may include, for example, distances or angles between anchor points. The UE performs positioning measurements for reference signals received from the anchor points. The UE performs outlier rejection of the positioning measurements using the relative position information. Positioning measurements selected by the UE using the relative position information are provided to a location server. The location server may perform UE-assisted positioning using the selected position measurements and the actual locations of the anchor points. Accordingly, the outlier rejection of the position measurements may be off loaded from the location server to the UE while maintaining confidentiality of the actual locations of the anchor points.
(FR) Un équipement utilisateur (UE) reçoit des données d'assistance en vue d'un positionnement qui comprennent des informations de position relative pour des points d'ancrage, tels que des stations de base et/ou des UE de liaison latérale. Les informations de position relative peuvent comprendre, par exemple, des distances ou des angles entre des points d'ancrage. L'UE effectue des mesures de positionnement pour des signaux de référence reçus provenant des points d'ancrage. L'UE effectue un rejet de valeurs aberrantes des mesures de positionnement à l'aide des informations de position relative. Des mesures de positionnement sélectionnées par l'UE à l'aide des informations de position relative sont fournies à un serveur de localisation. Le serveur de localisation peut effectuer un positionnement assisté par UE à l'aide des mesures de position sélectionnées et des emplacements réels des points d'ancrage. En conséquence, le rejet de valeurs aberrantes des mesures de position peut être déchargé du serveur de localisation à l'UE tout en maintenant la confidentialité des emplacements réels des points d'ancrage.
