Abstract

Selon des modes de réalisation, la présente invention concerne un procédé et un dispositif de commutation de planification, concernant le domaine des technologies de communication, pour résoudre le problème de la manière dont un terminal traite le cas où un intervalle de créneau reçu par le terminal est inférieur à un intervalle de créneau d'application minimum. Selon ledit procédé : un terminal reçoit des premières informations d'indication envoyées par un dispositif de réseau et utilisées pour indiquer la valeur de l'intervalle de créneau entre un PDCCH et un PDCCH planifié par le PDCCH, et si la valeur reçue par le terminal est inférieure à une valeur d'application minimum de l'intervalle de créneau entre le PDCCH et ledit PDSCH lorsque le terminal reçoit les premières informations d'indication, le terminal met à jour la valeur d'application minimum en fonction des premières informations d'indication ; ou le terminal reçoit des secondes informations d'indication envoyées par le dispositif de réseau et utilisées pour indiquer la valeur de l'intervalle de créneau entre le PDCCH et ledit PUSCH, et si la valeur reçue par le terminal est inférieure à la valeur d'application minimum de l'intervalle de créneau entre le PDCCH et ledit PUSCH, le terminal met à jour la valeur d'application minimum en fonction des secondes informations d'indication.
