Abstract

Les modes de réalisation de la présente demande concernent un procédé de communication sans fil, un dispositif terminal et un dispositif de réseau. Un dispositif terminal détermine, sur la base d'informations de position de celui-ci, si le dispositif terminal satisfait un critère cible correspondant à un mécanisme de relâchement de mesure RRM de cellule voisine ; et le dispositif terminal rapporte, à un réseau et au moyen d'informations d'indication, si le dispositif terminal satisfait le critère cible, de manière à aider le réseau à déterminer s'il faut exécuter une mesure RRM relâchée pour une cellule voisine. Le procédé de communication sans fil comprend les étapes suivantes : un dispositif terminal détermine, en fonction des informations de position de celui-ci, si le dispositif terminal satisfait un critère cible, le critère cible étant un critère correspondant à un mécanisme de relâchement de mesure RRM de cellule voisine ; et le dispositif terminal envoie des premières informations d'indication à un dispositif de réseau, les premières informations d'indication étant utilisées pour indiquer si le dispositif terminal satisfait le critère cible.
