Un procédé de libération de ressource comporte les étapes consistant à : émettre une signalisation de commande en voie descendante, ladite signalisation de commande en voie descendante étant utilisée pour enjoindre à l'équipement d'utilisateur UE de libérer la ressource de programmation semi-persistante (semi-persistent scheduling, SPS) en voie montante et la ressource de programmation semi-persistante en voie descendante. Un autre procédé de libération de ressource comporte les étapes consistant à : recevoir la signalisation de commande en voie descendante, ladite signalisation de commande en voie descendante étant utilisée pour enjoindre à l'équipement d'utilisateur UE de libérer la ressource de programmation semi-persistante en voie montante et la ressource de programmation semi-persistante en voie descendante ; libérer la ressource SPS en voie montante et la ressource SPS en voie descendante en fonction de la signalisation de commande en voie descendante. En appliquant les solutions techniques ci-dessus, le dispositif côté réseau peut faire en sorte que l'UE libère les ressources SPS montante et descendante à l'aide d'une seule signalisation de commande en voie descendante afin de réduire la charge de signalisation, résolvant ainsi le problème technique rencontré dans l'état antérieur de la technique où la charge de signalisation est conséquente lorsque la station de base d'évolution réalise la libération de la ressource SPS en voie montante et de la ressource SPS en voie descendante, et améliorant le rendement du système.
