Title (EN) A WIRELESS COMMUNICATION SYSTEM NODE WITH FIXED BEAMS
(FR) NŒUD DE SYSTÈME DE COMMUNICATION SANS FIL À FAISCEAUX FIXES
Abstract:
(EN) The present disclosure relates to a wireless communication system node (1), where the node (1) comprises at least two antenna ports (P1A, P1B, P1C, P1D; P2A, P2B, P2C, P2D). The node (1) further comprises a beamforming controller (2) and a 5 beamforming network (3) which in turn comprises at least two beam ports (4, 5, 6, 7; 8, 9, 10, 11) that are adapted to provide corresponding beams (12, 13, 14, 15; 16, 17, 18, 19). The beamforming controller (2) is arranged to control the beamforming network (3) such that the beams (12, 13, 14, 15; 16, 17, 18, 19) have a common envelope (20) in a desired plane, where the common envelope (20) is adapted to a 10 desired coverage for a certain communication system sector (37).
(FR) La présente invention concerne un nœud de système de communication sans fil (1), le nœud (1) comprenant au moins deux ports d'antenne (P1A, P1B, P1C, P1D ; P2A, P2B, P2C, P2D). Le nœud (1) comprend en outre un dispositif de commande de formation de faisceau (2) et un réseau de formation de faisceau (3) qui, à son tour, comprend au moins deux ports de faisceau (4, 5, 6, 7 ; 8, 9, 10, 11) qui sont conçus pour fournir des faisceaux correspondants (12, 13, 14, 15 ; 16, 17, 18, 19). Le dispositif de commande de formation de faisceau (2) est conçu pour commander le réseau de formation de faisceau (3) de telle sorte que les faisceaux (12, 13, 14, 15 ; 16, 17, 18, 19) ont une enveloppe commune (20) dans un plan souhaité, l'enveloppe commune (20) étant adaptée à une couverture souhaitée pour un certain secteur de système de communication (37).
