In a wireless network, plural downlink signals from plural base stations (210-1, 210-2, 210-3) are transmitted to a terminal (240). The plural downlink signals all carry the same information to the terminal (240). The terminal (240) provides feedback on the downlink channels. The feedback provides information on the taps of the channels. The amount of information fed back is constrained. Based on the feed-back, transmission parameters of the downlink signals are adjusted. The process of transmitting, providing feedback, and adjusting the parameters continue so that the energy of the downlink signal is enhanced at the terminal location and suppressed elsewhere. Beam forming can be used to further suppress the energy signature at locations other than the terminal location.

Dans un réseau sans fil, plusieurs signaux de liaison descendante provenant de plusieurs stations de base (210-1, 210-2, 210-3) sont transmis à un terminal (240). Les nombreux signaux de liaison descendante portent tous les mêmes informations au terminal (240). Le terminal (240) fournit une rétroaction sur les canaux de liaison descendante. La rétroaction fournit des informations sur les prises robinet des canaux. La quantité d'informations renvoyées est limitée. Sur la base de la rétroaction, les paramètres de transmission des signaux de liaison descendante sont ajustés. Le procédé de transmission, de fourniture de rétroaction et d'ajustement des paramètres continue de telle sorte que l'énergie du signal de liaison descendante est améliorée au niveau de l'emplacement de terminal et supprimée ailleurs. Une formation de faisceaux peut être utilisée pour supprimer davantage la signature d'énergie à des emplacements autres que l'emplacement de terminal.
