Abstract

L'invention concerne un procédé et un appareil de communication. Le procédé comprend les étapes suivantes : un dispositif réseau détermine des premières informations, et envoie les premières informations à un dispositif terminal, les premières informations donnant pour instruction au dispositif terminal de s'abstenir de mesurer une première ressource ou une partie de la première ressource, la première ressource étant une ressource RLM ou une ressource BFD. Après avoir reçu les premières informations, le dispositif terminal peut s'abstenir de mesurer la ressource RLM ou une partie de la ressource RLM. Le procédé décrit dans un mode de réalisation de la présente invention peut réduire la consommation d'énergie d'un dispositif terminal.
