(EN) STATISTICAL CHANNEL STATE INFORMATION REPORTING
(FR) RAPPORT D'INFORMATIONS D'ÉTAT DE CANAL STATISTIQUE
Abstract
(EN)
A method of operating a user equipment, UE, according to some embodiments includes performing (202) a channel measurement on a measurement resource for channel measurement, performing (204) two or more interference measurements on two or more measurement resources for interference measurement, for each interference measurement, determining (206) quality values associated with the interference measurement and the channel measurement, determining (208) a statistical measure based on the quality values, and transmitting (210) the statistical measure to a network node in a channel state information, CSI, report.
(FR)
Selon certains modes de réalisation, un procédé de fonctionnement d'un équipement utilisateur (UE) consiste à réaliser (202) une mesure de canal sur une ressource de mesure pour une mesure de canal, à réaliser (204) au moins deux mesures d'interférences sur au moins deux ressources de mesure pour une mesure d'interférences, à déterminer (206), pour chaque mesure d'interférences, des valeurs de qualité associées à la mesure d'interférences et à la mesure de canal, à déterminer (208) une mesure statistique sur la base des valeurs de qualité, et à transmettre (210) la mesure statistique à un nœud de réseau dans un rapport d'informations d'état de canal (CSI).
