Abstract

La présente divulgation concerne un procédé et un appareil de re-désactivation de planification semi-persistante, ainsi qu'un procédé et un appareil pour déterminer la re-désactivation d'une planification semi-persistante. Le procédé pour déterminer la re-désactivation d'une planification semi-persistante consiste à : selon une instruction d'un dispositif côté réseau, déterminer le type de planification semi-persistante devant être re-désactivée. Dans la présente divulgation, lorsqu'un dispositif côté réseau ordonne à un terminal de re-désactiver une SPS, le dispositif côté réseau peut indiquer, au terminal, le type de SPS à re-désactiver et, en conséquence, le terminal peut déterminer avec précision le type de SPS qui doit être re-désactivé, de manière à re-désactiver le type correspondant de SPS et le terminal arrête de communiquer avec le dispositif côté réseau au moyen d'une configuration de SPS à re-désactiver, ce qui empêche un effet de communication d'être affecté en raison de la re-désactivation d'un type incorrect de SPS.
