Abstract

L'invention concerne une unité de traitement 120 qui comprend, en tant que pluralité d'unités de fonctions de machines esclaves, une unité de fonction de machine esclave compatible avec des procédures élémentaires mono-antennes capable de traiter un signal de commande conforme aux procédures élémentaires mono-antennes dans lesquelles un seul déphaseur est attribué à une unité de fonction de machine esclave, et prévue pour chaque déphaseur d'un ou de plusieurs déphaseurs, et au moins une unité de fonction de machine esclave compatible avec des procédures élémentaires à antennes multiples prévue pour un ou plusieurs déphaseurs et capable de traiter un signal de commande conforme à des procédures élémentaires à antennes multiples dans lesquelles un ou plusieurs déphaseurs peuvent être attribués à une unité de fonction de machine esclave. Lors de la réception d'un signal de commande conforme soit à des procédures élémentaires mono-antennes, soit à des procédures élémentaires à antennes multiples à partir d'une machine maître 400, l'unité de traitement 120 détermine si la destination du signal de commande est une unité de fonction de machine esclave compatible avec des procédures élémentaires mono-antennes ou des procédures élémentaires à antennes multiples. Si la destination est l'unité de fonction de machine esclave compatible avec des procédures élémentaires mono-antennes, l'unité de traitement 120 amène l'unité de fonction de machine esclave à exécuter un traitement sur la base du signal de commande conforme aux procédures élémentaires mono-antennes, et si la destination est l'unité de fonction de machine esclave compatible avec des procédures élémentaires à antennes multiples, elle amène l'unité de fonction de machine esclave à exécuter un traitement sur la base du signal de commande conforme aux procédures élémentaires à antennes multiples.
