Fecha de publicación: 21/12/2023 Fuente: Wipo "IOT" A wireless node (e.g., an IoT reader such as a UE or a base station) may transmit, to an IoT device (e.g., an IoT tag), and the IoT device may receive, from the wireless node, timing information. The wireless node and the IoT device may communicate via a TDD system. The timing information may be associated with communication of a response from the IoT device. The IoT device may transmit, to the wireless node, and the wireless node may receive, from the IoT device, the response based on the timing information. In some configurations, the wireless node may operate in a half duplex mode. In some configurations, the IoT device may be a passive IoT device that may transmit information based on backscatter communication.
