Title (EN) BEAMFORMING BASED ON COMBINED BEAMS
(FR) FORMATION DE FAISCEAU BASÉE SUR DES FAISCEAUX COMBINÉS
Abstract:
(EN) There is provided mechanisms for beamforming. A method is performed by a network node. The network node is capable of communicating with served wireless devices using multiple beams generated by analog beamforming in an antenna array. The method comprises identifying, based on statistics of handovers of the served wireless devices between the beams, a need to combine at least two of the beams into a new beam. The method comprises determining beamforming weights to be applied at the analog antenna array for generating the new beam. The method comprises communicating with the served wireless devices using the new beam with the determined beamforming weights having been applied at the analog antenna array.
(FR) L'invention concerne des mécanismes de formation de faisceau. Un procédé est exécuté par un nœud de réseau. Le nœud de réseau est capable de communiquer avec des dispositifs sans fil desservis à l'aide de multiples faisceaux générés au moyen d'une formation de faisceau analogique dans un réseau d'antennes. Le procédé consiste à identifier, sur la base de statistiques de transferts des dispositifs sans fil desservis entre les faisceaux, un besoin de combiner au moins deux des faisceaux en un nouveau faisceau. Le procédé consiste à déterminer des pondérations de formation de faisceau à appliquer au niveau du réseau d'antennes analogiques pour générer le nouveau faisceau. Le procédé consiste à communiquer avec les dispositifs sans fil desservis à l'aide du nouveau faisceau, les pondérations de formation de faisceau déterminées ayant été appliquées au niveau du réseau d'antennes analogiques.
