Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing resource allocation methods are used for Ambient IoT devices, then resource allocation is simple, but interference with legacy UEs occurs and communication quality deteriorates
Solution Approach 1:
The patent segments the wireless communication resources by introducing dedicated slots, channels, and resource reservation windows specifically for Ambient IoT devices. This segmentation separates Ambient IoT device transmissions from legacy UE transmissions, eliminating interference while maintaining simple resource allocation through dedicated resource pools.
Solution Approach 2:
The patent applies local quality by creating specialized resource allocations with specific characteristics for Ambient IoT devices, including passive and active communication modes. Different resource types (dedicated slots, channels, reservation windows) are tailored to the unique energy harvesting and transmission characteristics of Ambient IoT devices, improving communication quality without affecting legacy UEs.
2Reliability
If dedicated slots and channels are introduced for Ambient IoT devices, then communication quality improves, but device complexity increases
Solution Approach 1:
The patent achieves universality by designing a resource allocation framework that handles both passive and active communication modes of Ambient IoT devices using the same dedicated slots and channels. The resource reservation windows and slot structures are multi-functional, supporting different transmission types without requiring separate complex allocation mechanisms for each mode.
Solution Approach 2:
The patent applies preliminary action by pre-configuring dedicated slots, channels, and resource reservation windows for Ambient IoT devices before actual communication occurs. This advance preparation simplifies real-time resource allocation, as the structure and parameters are predetermined, reducing the complexity of dynamic resource management while ensuring high communication quality.
3Object-affected harmful factors
If resource reservation windows are implemented, then interference with legacy UEs is reduced, but time resources are consumed
Solution Approach 1:
The patent implements periodic action through resource reservation windows that are allocated at regular intervals for Ambient IoT device transmissions. This periodic structure allows legacy UEs to predict and avoid these time slots, eliminating interference while minimizing time consumption by concentrating Ambient IoT transmissions in specific periodic windows rather than continuously occupying resources.
Solution Approach 2:
The patent transitions to another dimension by introducing resource reservation windows as a temporal dimension for resource allocation. Instead of only frequency or spatial separation, the reservation windows create a time-based dimension that allows Ambient IoT devices to transmit without interfering with legacy UEs, efficiently utilizing time resources through structured periodic allocations.
