Title (EN) ANTENNA SYSTEM FOR DUAL TRANSMISSION
(FR) SYSTÈME D'ANTENNE POUR TRANSMISSION DOUBLE
Abstract:
(EN) The proposed technology provides an antenna system (1) for dual transmission. The antenna system comprises an antenna column (10) carrying a plurality of antenna elements (15). The plurality of antenna elements (15) comprises a first set (16) of antenna elements dedicated to a first radio unit (100) for performing a first mode of transmission and a second set (17) of antenna elements dedicated to a second radio unit (200) for performing a second mode of transmission. The second mode of transmission being different from the first mode of transmission and comprising beam formed transmissions. The first set (16) and the second set (17) of antenna elements (15) of the antenna column (10) being adapted to perform transmissions according to the first and second modes of transmission simultaneously. The proposed technology also provides methods, devices and computer programs for controlling such an antenna system.
(FR) La technologie proposée fournit un système d'antenne (1) pour une transmission double. Le système d'antenne comprend une colonne d'antenne (10) portant une pluralité d'éléments d'antenne (15). La pluralité d'éléments d'antenne (15) comprend un premier ensemble (16) d'éléments d'antenne dédiés à une première unité radio (100) pour réaliser un premier mode de transmission et un second ensemble (17) d'éléments d'antenne dédiés à une seconde unité radio (200) pour effectuer un second mode de transmission. Le second mode de transmission est différent du premier mode de transmission et comprend des transmissions formées par faisceau. Le premier ensemble (16) et le second ensemble (17) d'éléments d'antenne (15) de la colonne d'antenne (10) sont conçus pour effectuer des transmissions selon les premier et second modes de transmission simultanément. La technologie proposée fournit également des procédés, des dispositifs et des programmes informatiques pour commander un tel système d'antenne.
