Abstract

La présente invention, qui appartient au domaine technique des communications, concerne un procédé, un appareil et un système de communication qui sont utilisés pour garantir la qualité de transmission de données d'un terminal tout en garantissant également une réduction de la consommation d'énergie. Dans la solution selon l'invention : un premier terminal reçoit, d'un dispositif de communication, une première configuration de réception discontinue (DRX) et/ou des informations de configuration d'une première ressource temporelle, la première configuration de DRX comprenant des informations de configuration à une première période inactive, les informations de configuration à la première période inactive étant utilisées pour indiquer que le premier terminal est dans un état inactif durant la première période inactive, et la première ressource temporelle étant une ressource temporelle pour permettre au premier terminal de détecter une ressource de liaison latérale; et lorsque la première période inactive est en conflit avec la première ressource temporelle, le premier terminal envoie des premières informations au dispositif de communication, les premières informations étant utilisées pour indiquer que la première période inactive est en conflit avec la première ressource temporelle.
