Abstract

L'invention concerne des procédés, des systèmes et des dispositifs destinés aux communications sans fil. Les techniques de l'invention peuvent prendre en charge la détermination d'une formation de faisceau analogique et d'une formation de faisceau numérique pour des transmissions de SRS. Un équipement utilisateur (UE) peut recevoir un premier message de commande qui indique une ressource d'informations d'état de canal (CSI-RS) permettant de déterminer un précodage pour un ensemble de ressources d'un signal de référence de sondage (SRS), et la ressource CSI-RS peut être associée à une première configuration de faisceau. L'UE peut recevoir un second message de commande qui indique une seconde configuration de faisceau pour transmettre un SRS dans l'ensemble de ressources SRS. La seconde configuration de faisceau peut être associée à la première configuration. L'UE peut recevoir le CSI-RS en fonction de la première configuration de faisceau et transmettre un ou plusieurs SRS conformément à l'ensemble de ressources SRS d'après la seconde configuration de faisceau.
