Abstract[English]
Various aspects of the present disclosure relate to wireless device communication for energy harvesting. A wireless device, such as an Ambient Internet of Things (IoT) device, can be in one of multiple different states, including at least one of a transmit and receive state, a receive state, and a sleep or energy harvesting state. The wireless device transitions between states based at least in part on an amount of energy that is stored at the wireless device, and optionally on one or more additional criteria (e.g., whether the wireless device has data to transfer). The wireless device transmits to a reader device an indication of the new state that the wireless device is transitioning to or has transitioned to. The wireless device also transmits to the reader device an indication of a duration for which the wireless device can operate in the new state.[French]
Divers aspects de la présente divulgation concernent la communication par dispositif sans fil pour la collecte d'énergie. Un dispositif sans fil, tel qu'un dispositif de l'internet des objets (IdO) ambiant, peut être dans l'un de multiples états différents, comprenant un état de transmission et de réception, et/ou un état de réception et/ou un état de veille ou de collecte d'énergie. Le dispositif sans fil effectue des transitions entre des états sur la base, au moins en partie, d'une quantité d'énergie qui est stockée au niveau du dispositif sans fil, et facultativement sur un ou plusieurs critères supplémentaires (par exemple, si le dispositif sans fil a des données à transférer). Le dispositif sans fil transmet à un dispositif de lecture une indication du nouvel état vers lequel le dispositif sans fil est en cours de transition ou a transité. Le dispositif sans fil transmet également au dispositif de lecture une indication d'une durée pendant laquelle le dispositif sans fil peut fonctionner dans le nouvel état.
