Abstract

La présente invention concerne un procédé et un appareil permettant de déterminer un temps actif. Le procédé comprend les étapes suivantes : un canal logique de liaison montante d'un équipement utilisateur déclenche l'équipement utilisateur pour envoyer une demande de planification (SR) sur un canal de commande de liaison montante physique (PUCCH), une entité MAC de l'équipement utilisateur configurant de multiples groupes de réception discontinue ; l'équipement utilisateur acquiert au moins un groupe de réception discontinue correspondant à des informations de restriction de transmission d'un canal logique de liaison montante ; et l'équipement utilisateur entre dans un temps actif de réception discontinue sur l'au moins un groupe de réception discontinue en fonction des informations de restriction de transmission du canal logique de liaison montante. Le procédé et l'appareil permettant de déterminer le temps actif selon les modes de réalisation de la présente invention peuvent non seulement garantir les performances de planification, mais prennent également en compte l'économie d'énergie d'un terminal.
