Abstract

L'invention concerne un procédé de rapport de faisceau associé à une ou plusieurs configurations de groupe d'antennes (AGC). Le nœud de réseau configure un ou plusieurs AGC. Chaque AGC peut comprendre au moins l'un des indices AGC. Chaque AGC peut comprendre le nombre de ports ou de couches qui peuvent être pris en charge par l'UE. De plus, chaque AGC peut comprendre un état de panneau actif. L'état de panneau actif peut indiquer si l'UE peut effectuer une transmission UL vers le nœud de réseau et/ou si l'UE peut effectuer une réception DL à partir du nœud de réseau. L'UE peut déterminer l'un des AGC pour chaque CRI ou SSBRI dans un rapport de faisceau. L'UE peut activer et sélectionner un ou plusieurs panneaux pour une réception DL et une transmission UL, et l'UE peut recevoir et mesurer le signal de référence correspondant au CRI ou SSBRI dans le rapport de faisceau.
