Abstract

Les modes de réalisation de la présente divulgation divulguent un procédé de réception et d'envoi d'informations de précodage et un appareil associé. Le procédé est exécuté par un premier dispositif côté réseau, le procédé consistant à : obtenir une valeur de capacité d'un second dispositif côté réseau, la valeur de capacité étant utilisée pour représenter le temps requis par le second dispositif côté réseau pour réaliser le décodage d'informations de commande et réaliser une commutation matérielle ; et envoyer au second dispositif côté réseau des informations d'indication de matrice de précodage ou des informations d'indication de faisceau. Dans la solution technique des modes de réalisation de la présente divulgation, des informations d'indication peuvent être envoyées au second dispositif côté réseau lorsque la communication est effectuée par l'intermédiaire d'un répéteur ou d'une RIS, de sorte que le second dispositif côté réseau effectue une commutation de faisceau ou de matrice de précodage du répéteur et de la RIS sur la base des informations d'indication de façon à s'adapter au changement d'informations de précodage ou de faisceau, ce qui permet d'améliorer la fiabilité de communication.
