Abstract

L'invention concerne un procédé de communication et un dispositif terminal, qui se rapportent au domaine technique des communications sans fil. Le procédé est utilisé pour réduire la consommation d'énergie du dispositif terminal. Dans le procédé, un dispositif terminal peut recevoir un signal de PoSS. Lorsque la qualité de signal du signal de PoSS est inférieure ou égale à un premier seuil, le dispositif terminal peut se réveiller au cours d'une première période de DRX, ou le dispositif terminal se réveille ou entre en sommeil au cours de la première période de DRX selon un état de réveil ou de sommeil au cours de la période de DRX qui précède la première période de DRX. Sur cette base, lorsque le dispositif terminal peut ne pas être capable de démoduler avec exactitude le signal de PoSS de façon à acquérir une indication d'un dispositif de réseau, le dispositif terminal peut se réveiller directement au cours de la première période de DRX, ou peut se réveiller ou entrer en sommeil au cours de la première période de DRX selon l'état de réveil ou de sommeil du dispositif terminal au cours de la période de DRX qui précède la première période de DRX, de telle sorte que la consommation d'énergie du dispositif terminal peut être réduite, et des retards temporels de programmation de données causés par une détection manquée du signal de PoSS peuvent également être réduits.
