Abstract

Certains modes de réalisation de la présente invention concernent un procédé, un appareil et un système de communication. Le procédé comporte les étapes suivantes : un dispositif terminal, lorsqu'il est dans un état connecté, reçoit des premières informations en provenance d'un dispositif de réseau, les premières informations comportant des informations de configuration de signal de référence, et étant utilisées pour indiquer que les informations de configuration de signal de référence sont utilisées lorsque le dispositif terminal est dans un état non connecté ; les informations de configuration de signal de référence sont stockées ; et le dispositif terminal, lorsqu'il est dans un état non connecté, reçoit un signal de référence en provenance du dispositif de réseau selon les informations de configuration de signal de référence. De cette façon, il n'est pas nécessaire que le dispositif terminal, lorsqu'il est dans un état non connecté, se réveille plus tôt d'un état de sommeil pour recevoir le signal de référence, ce qui réduit la consommation d'énergie du dispositif terminal. En outre, étant donné que les informations de configuration de signal de référence à utiliser par le dispositif terminal dans un état non connecté sont reçues en provenance du dispositif de réseau par le dispositif terminal dans un état connecté, il n'est pas nécessaire d'introduire des informations de configuration au niveau de la cellule.
