Abstract

L'invention concerne une méthode et un dispositif d'envoi d'informations d'état de canal (CSI). La méthode d'envoi consiste à : obtenir par un terminal N ressources canaux physiques partagés de liaison montante (PUSCH) pour envoyer les CSI, N étant un entier supérieur ou égal à 1 ; le terminal envoyant les CSI sur les N ressources PUSCH en fonction d'une règle prédéterminée. La règle prédéterminée comprend un des éléments suivants : lorsque N=1, le terminal envoie les CSI sur la ressource ; lorsque N est supérieur à 1, le terminal divise les CSI en N groupes, chaque groupe correspond à une ressource PUSCH, et les CSI du groupe correspondant sont envoyées sur la ressource PUSCH correspondante ; lorsque N est supérieur à 1, le terminal sélectionne une ressource PUSCH des N ressources PUSCH, et le terminal envoie les CSI sur la ressource PUSCH sélectionnée. La présente invention peut réduire efficacement le retard du rapport CSI, ce qui améliore la performance du système.
