Abstract

Les modes de réalisation de la présente invention concernent des procédés, des dispositifs et des supports lisibles par ordinateur destinés à des communications. Selon des modes de réalisation de la présente invention, un dispositif terminal reçoit une configuration de ressources de Signal de référence (RS) pour un Point d'émission et de réception (TRP) en provenance d'un serveur de localisation. La configuration de ressources RS indique une pluralité d'ensembles de ressources RS qui comprennent des ressources RS se chevauchant partiellement. Le dispositif terminal transmet des premières informations pour déterminer une ressource RS parmi la pluralité d'ensembles de ressources RS à un dispositif de réseau associé au TRP. Ensuite, le dispositif terminal reçoit un RS sur la ressource RS déterminée sur la base des premières informations provenant du dispositif de réseau.
