Abstract

La présente invention concerne un procédé, un appareil et un dispositif de communication. Le procédé comprend les étapes suivantes : un dispositif terminal acquiert des premières informations correspondant à un temporisateur de temps de propagation aller-retour de demande de répétition automatique hybride à réception discontinue (DRX-HARQ-RTT), les premières informations étant obtenues selon des informations de mouvement du dispositif terminal et des informations de mouvement d'un dispositif de réseau ; et le dispositif terminal règle le temporisateur DRX-HARQ-RTT du dispositif terminal selon les premières informations. Par conséquent, la consommation d'énergie du dispositif terminal est relativement faible, et la performance du dispositif de réseau pour planifier le dispositif terminal est relativement élevée.
