Abstract[English]
Example embodiments of the disclosure relate to methods, apparatuses, and computer readable storage medium for beam quality determination based on Gram matrix of a Multiple Input Multiple Output Channel In the methods, a first apparatus determines a channel matrix based on at least one reference signal. The at least one reference signal is transmitted using at least one transmission beam among a set of transmission beams by a second apparatus and received using at least one reception beam among a set of reception beams by the first apparatus. The first apparatus determines a Gram matrix associated with a channel capacity based on the channel matrix and determines a beam quality for at least one of the at least one transmission beam or the at least one reception beam based on the Gram matrix.[French]
Des modes de réalisation donnés à titre d'exemple de la divulgation concernent des procédés, des appareils et un support de stockage lisible par ordinateur pour une détermination de qualité de faisceau sur la base d'une matrice de Gram d'un canal à entrées multiples et sorties multiples. Dans les procédés, un premier appareil détermine une matrice de canal sur la base d'au moins un signal de référence. Le ou les signaux de référence sont transmis à l'aide d'au moins un faisceau de transmission parmi un ensemble de faisceaux de transmission par un second appareil et reçus à l'aide d'au moins un faisceau de réception parmi un ensemble de faisceaux de réception par le premier appareil. Le premier appareil détermine une matrice de Gram associée à une capacité de canal sur la base de la matrice de canal et détermine une qualité de faisceau pour le ou les faisceaux de transmission et/ou le ou les faisceaux de réception sur la base de la matrice de Gram.
