Abstract:
(EN) The present invention relates to a method for performing beamforming by using circular array antennas comprising a plurality of antennas, and a device therefor, and to a method and a device therefor, the method comprising the steps of: determining the number of operating antennas for a specific beam pattern; selecting at least one antenna among the plurality of antennas by using the determined number of operating antennas; and transmitting a signal through the selected at least one antenna, wherein the step of determining the number of operating antennas determines the number of operating antennas by using the inverse number of the square of the vertical beam width of the specific beam pattern.
(FR) La présente invention concerne un procédé pour effectuer une formation de faisceau à l'aide d'antennes à réseau circulaire comprenant une pluralité d'antennes, et un dispositif associé, et un procédé et un dispositif associés, le procédé comprenant les étapes consistant à : déterminer le nombre d'antennes en fonctionnement pour un diagramme de faisceau spécifique; sélectionner au moins une antenne parmi la pluralité d'antennes en utilisant le nombre déterminé d'antennes en fonctionnement; et émettre un signal par l'intermédiaire desdites antennes sélectionnées, l'étape de détermination du nombre d'antennes en fonctionnement consistant à déterminer le nombre d'antennes en fonctionnement en utilisant le nombre inverse du carré de la largeur de faisceau verticale du diagramme de faisceau spécifique.
