Abstract
(EN)
A first apparatus may transmit, to a user equipment (UE), on a control channel, one or more indications of one or more beam indexes corresponding to one or more beams. The first apparatus may transmit, to the UE, one or more reference signals through the one or more beams corresponding to the one or more beam indexes. The reference signals may be used by the UE to select a best subarray and/or receive combiner for communication with the first apparatus.

(FR)
Selon l’invention, un premier appareil peut transmettre, à un équipement d’utilisateur (UE), sur un canal de contrôle, une ou plusieurs indications d’un ou plusieurs index de faisceaux correspondant à un ou plusieurs faisceaux. Le premier appareil peut transmettre, à l’UE, un signal ou plusieurs signaux de référence par le ou les faisceaux correspondant à l’index ou aux index de faisceaux. Les signaux de référence peuvent être utilisés par l’UE pour sélectionner un meilleur sous-réseau et/ou recevoir un combineur de communication avec le premier appareil.
