Abstract: front page image
(EN)The present invention relates to a method for beamforming in cooperative multi-cell MIMO based on alleviated zero-forcing and to a method for transmitting same. The method includes the steps of: designing a beam to be transmitted to user terminals through a method for alleviated zero-forcing beamforming; and transmitting the designed beam. In addition, the method for transmitting information according to the present invention includes the steps of: forming a transmission beam through a predetermined equation; and transmitting information using the transmission beam.
(FR)La présente invention concerne un procédé de conformation de faisceau dans un MIMO coopératif à cellules multiples basé sur un forçage à zéro atténué et un procédé pour son émission. Le procédé comporte les étapes consistant à : concevoir un faisceau à émettre vers des terminaux d'utilisateurs par un procédé de conformation de faisceau avec forçage à zéro atténué ; et émettre le faisceau conçu. De plus, le procédé d'émission d'informations selon la présente invention comprend les étapes consistant à : former un faisceau d'émission par l'intermédiaire d'une équation prédéterminée ; et émettre des informations à l'aide du faisceau d'émission.
