Abstract

Selon des modes de réalisation, la présente demande concerne un procédé de transmission d'informations, un dispositif réseau, un équipement utilisateur, un système de communication, un dispositif électronique et un support de stockage. Le procédé consiste à : déterminer une première valeur de poids lorsqu'un équipement utilisateur est dans un mode de transmission SU-MIMO ; déterminer une seconde valeur de poids en fonction de la première valeur de poids lorsque l'équipement utilisateur est dans un état MU-MIMO ; et envoyer, d'après la seconde valeur de poids, des informations à transmettre à l'équipement utilisateur. Une valeur de poids (c'est-à-dire la seconde valeur de poids) dans un mode de transmission MU-MIMO est déterminé en fonction d'une valeur de poids (c'est-à-dire, la première valeur de poids) dans le mode de transmission SU-MIMO, afin d'éviter les problèmes techniques de la technologie associée, à savoir une consommation élevée des ressources CSI et une longue durée, provoqués par un procédé de traversée d'une pluralité de schémas de mesure, ce qui permet d'obtenir les effets techniques de réduction des ressources CSI et d'amélioration de l'efficacité.
