Fuente: Wipo "IOT" Example embodiments of the present disclosure relate to Ambient Internet of Things (A-IoT) device ID management. According to example embodiments, a system may include an A-IoT reader that may be configured to determine a Device-to-Reader (D2R) transmission failure. Accordingly, the A-IoT device may determine whether a retransmission of a device identifier (ID) associated with an A-IoT device is required. Accordingly, based on determining that the retransmission of the device ID is not required, the A-IoT device may provide, to the A-IoT device and during a Reader-to-Device (R2D) transmission, a first R2D message indicating that the device ID can be reused. On the other hand, based on determining that the retransmission of the device ID is required, the A-IoT reader may provide, to the A-IoT device and during the R2D transmission, a second R2D message that requests the A-IoT device to retransmit the device ID during a next D2R transmission.
