Abstract

La présente divulgation se rapporte au domaine des communications et concerne un procédé et un appareil de communication, ainsi qu'un dispositif et un support de stockage lisible. Le procédé consiste à : envoyer un signal d'activation à un second terminal, le signal d'activation servant à fournir de l'énergie pour le second terminal ; et recevoir un message de réponse envoyé par le second terminal sur la base de l'énergie collectée à partir du signal d'activation. L'énergie est fournie au second terminal au moyen du signal d'activation, de sorte que le second terminal peut collecter de l'énergie à partir du signal d'activation, et le message de réponse est renvoyé au second terminal sur la base de l'énergie collectée, ce qui permet de mettre en œuvre la réception de signaux et l'envoi de messages d'un terminal passif sans batterie ou d'un terminal passif à alimentation limitée en énergie, et d'augmenter une plage de couverture de scénario de l'Internet des objets.
