Abstract

La présente invention concerne un procédé, un dispositif et un système de transmission d'informations de canal. Le procédé est appliqué à un équipement d'utilisateur (UE) doté d'une réception discontinue (DRX), et consiste à : transmettre des informations de canal selon une indication de transmission configurée par un côté réseau et basée sur une ressource de transmission prédéfinie, l'indication de transmission étant utilisée pour indiquer que l'UE peut transmettre les informations de canal pendant un temps de non-activation ou un temps de non-continuité de la réception DRX. Au moyen du mode de réalisation, l'UE peut transmettre les informations de canal durant un temps de non-activation ou un temps de non-continuité selon l'indication de transmission configurée par le côté réseau, de sorte que les informations de canal obtenues par le côté réseau puissent mieux refléter la qualité du canal dans un temps d'activation ultérieur et puissent optimiser une politique de planification de la transmission de données durant un temps d'activation à démarrer, ce qui augmente le débit de l'UE et la qualité de la transmission.
