Abstract

La présente invention concerne un procédé et un appareil de planification de créneau temporel, se rapportant au domaine des communications. Le procédé consiste : à acquérir la longueur de données de données, le terminal d'envoi ou le terminal de réception desdites données étant un équipement utilisateur (UE) ; sur la base de la longueur de données, à attribuer N créneaux temporels consécutifs pour les données ; à configurer une période de temps de commutation pour le dernier créneau temporel parmi les N créneaux temporels, et ne pas configurer de période de temps de commutation pour au moins l'un des N créneaux temporels restants, la période de temps de commutation étant utilisée pour commuter le faisceau d'onde correspondant à l'UE ; à notifier à l'UE les N créneaux temporels et, sur la base d'un premier format configuré pour les N créneaux temporels, à envoyer ou à recevoir des données sur les N créneaux temporels, l'UE étant utilisé pour déterminer le premier format sur la base de la notification, et à traiter de manière correspondante les données sur les N créneaux temporels sur la base du premier format. La présente invention résout le problème de gaspillage de ressource en conséquence de la réservation d'une période de temps de commutation pour chaque créneau temporel, et obtient l'effet d'économie de ressources.
