Abstract

La présente invention concerne un procédé, un appareil et un produit programme d'ordinateur pour un hachage spatial pour des espaces de recherche de canal de commande améliorés. La présente invention consiste à définir un espace de recherche de canal de commande pour rechercher des canaux de commande candidats, à définir des emplacements d'espace de recherche à l'intérieur de l'espace de recherche, à grouper les emplacements d'espace de recherche en une pluralité de sous-ensembles d'emplacements d'espace de recherche, à associer chaque sous-ensemble d'emplacements d'espace de recherche à un port d'antenne, pour chacune d'une pluralité de sous-trames, à changer les emplacements d'espace de recherche d'un premier sous-ensemble d'emplacements d'espace de recherche à un second sous-ensemble d'emplacements d'espace de recherche.
