Abstract

L'invention concerne un procédé de configuration d'une ressource de signal de référence de sondage (SRS) de liaison montante pour des équipements utilisateurs ayant de multiples panneaux pour une acquisition d'informations d'état de canal (CSI) de liaison descendante dans un réseau de communication cellulaire. Un équipement utilisateur ayant de multiples panneaux rapporte sa capacité d'antenne à une station de base. La capacité d'antenne comprend un certain nombre de panneaux d'équipement utilisateur et une période de garde minimale pour une commutation de panneau. En réponse, l'équipement utilisateur reçoit une configuration de ressources de signal SRS en provenance de la station de base. La configuration de ressources de signal SRS attribue des ressources de signal SRS avec une période de garde pour une commutation de panneau. L'équipement utilisateur effectue par conséquent une transmission de signal SRS en liaison montante. La station de base mesure des signaux SRS de liaison montante et obtient des informations CSI de liaison descendante à l'aide des résultats de mesure de signal SRS de liaison montante.
