Ambient AIoT Error Messaging Through Device-to-Reader Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambient power-enabled AIoT devices, such as battery-less IoT devices, face challenges in informing network nodes of errors during IoT operations, leading to increased signaling and operation failures due to the lack of mechanisms for error reporting.
Innovation Solution
AIoT devices are enabled to transmit device-to-reader messages containing error information, allowing network nodes to modify or update the requested operations based on the received error information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If ambient power-enabled AIoT devices are used, then device complexity and power consumption are reduced, but the ability to report errors to network nodes is lost
Solution Approach 1:
The patent implements a feedback mechanism where AIoT devices send error information messages back to network nodes when errors occur during IoT operations. This allows ambient power-enabled devices to report errors without requiring complex local processing or storage capabilities, maintaining simplicity while enabling error reporting through a straightforward uplink message transmission.
2Reliability
If error reporting mechanisms are added to AIoT devices, then error information can be transmitted, but device complexity increases
Solution Approach 1:
The patent extracts the error reporting functionality from the device side and places it in the network side. Network nodes are configured to receive and process error information messages from AIoT devices, performing the complex error analysis and response generation centrally rather than requiring complex error handling capabilities in each simple AIoT device.
3Reliability
If AIoT devices transmit error messages, then network nodes can adjust operations, but signaling overhead increases
Solution Approach 1:
The patent implements partial error reporting where AIoT devices transmit only essential error information (error type indicators) rather than complete detailed error logs. This partial action approach provides sufficient information for network nodes to adjust operations while minimizing the signaling overhead and energy consumption associated with transmitting comprehensive error data.

AI summary
Various aspects of the present disclosure relate to error messaging during Internet of Things (IoT) operations. For example, an ambient IoT (AIoT) device may transmit messages to network nodes when errors occur during requested IoT operations. The AIoT device may transmit device to reader (D2R) messages that contain error information representative of the errors (or error types) during the IoT operation. Using the error information, a network node may perform actions to modify or update the requested IoT operation, such as by resending a message that contains updated or appropriate data for the IoT operation.
