Abstract

Sont divulgués ici des appareils, des procédés et des systèmes pour la configuration d'un rapport de CSI. Un procédé (1000) consiste à recevoir (1002) au moins un paramètre de rapport de CSI. Ledit paramètre de rapport de CSI comprend au moins un paramètre de ressources de RS de CSI, et le paramètre de rapport de CSI comprend une indication de rapport de retour d'informations de CSI pour de multiples points d'émission dans un réseau de communication mobile. Le procédé (1000) consiste à identifier (1004) un ensemble d'hypothèses d'émission sur la base du paramètre de rapport de CSI. Les hypothèses comprennent une combinaison d'une émission à point unique à partir d'au moins un TRP ou d'une émission conjointe multi-points à partir de deux TRP. Le procédé (1000) consiste à recevoir (1006) au moins une ressource de signal de référence de CSI émise à partir du réseau de communication mobile sur la base du paramètre de ressources de signaux de référence de CSI. Le procédé (1000) consiste à générer (1008) un ensemble d'un ou plusieurs rapports de CSI sur la base du paramètre de rapport de CSI.
