Abstract

La présente demande concerne un procédé de transmission d'informations multiantenne, un dispositif de réseau et un support de stockage, et se rapporte au domaine technique des communications. Le procédé consiste à : détecter un degré de congestion de liaison descendante d'une unité radio distante (RRU) et détecter l'état de présence d'un service cible, de façon à obtenir un résultat de détection ; sur la base du résultat de détection, déterminer un mode de fonctionnement de la RRU, chaque port d'émission de la RRU dans différents modes de fonctionnement étant dans différents états de fonctionnement ; et transmettre des informations à un côté terminal au moyen du mode de fonctionnement déterminé de la RRU.
