Abstract

Selon certains modes de réalisation, la présente invention concerne un procédé de communication sans fil et un dispositif terminal. La durée de surveillance d'un PDCCH peut être réduite, de façon à atteindre l'objectif d'économie d'énergie. Le procédé comprend les étapes suivantes consistant à : un dispositif terminal envoie une demande de planification à un dispositif de réseau ; une entité MAC du dispositif terminal détermine s'il faut commencer à entrer un temps d'activité d'un cycle DRX après que la demande de planification a été envoyée, le cycle DRX étant configuré pour l'entité MAC du dispositif terminal.
