Abstract:
(EN) The method of weight factor matrix determination for beam forming according to one aspect of the present invention enables a weight factor matrix to be determined to eliminate interference among cells, and comprises a step wherein a first transmission power to the target terminal of first terminal and second transmission power to the target terminal of a first terminal and second transmission power to second terminals excluding the target terminal are determined; a step wherein the eigen value with respect to the ratio of the first transmission power to the second transmission power is used to calculate its eigen vector; and a step wherein the eigen vector calculated is used to determine the weight factor matrix in the serving base station.
(FR) L'invention concerne un procédé de détermination d'une matrice de facteur de poids pour la formation d'un faisceau. Selon un aspect de la présente invention, le procédé permet de déterminer une matrice de facteur de poids pour éliminer l'interférence entre les cellules, et comprend une étape de détermination d'une première puissance de transmission à un terminal cible du premier terminal et une deuxième puissance de transmission au terminal cible d'un premier terminal et une deuxième puissance de transmission aux deuxièmes terminaux à l'exclusion du terminal cible ; une étape d'utilisation de la valeur propre par rapport au rapport de la première puissance de transmission sur la deuxième puissance de transmission pour calculer son vecteur propre ; et une étape d'utilisation du vecteur propre calculé pour déterminer la matrice de facteur de poids dans la station de base de service.
