Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, forwarding nodes face challenges in efficiently managing control information, leading to increased network resource consumption and potential communication errors due to inaccurate control information selection by wireless communication devices.
Innovation Solution
A forwarding node is configured to operate in a WCD-controlled operation mode, where it selects and transmits an indication of the operation mode based on parameters like channel conditions and mobility, allowing it to autonomously identify and reduce the amount of control information required from wireless communication devices, thereby optimizing resource usage and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the forwarding node uses WCD-controlled operation mode to autonomously select control information, then network resource consumption is reduced, but the risk of inaccurate control information selection increases
Solution Approach 1:
The forwarding node autonomously selects control information without requiring explicit control messages from the WCD, reducing network resource consumption. The forwarding node uses its own measurements and decisions to determine operational parameters, thereby minimizing the need for control signaling while maintaining operational capability.
Solution Approach 2:
The forwarding node continuously monitors channel conditions and communication quality, using this feedback to dynamically adjust its control information selection. This feedback mechanism ensures that the autonomously selected control information remains accurate and adaptive to changing network conditions, resolving the reliability concern.
2Quantity of substance
If the forwarding node autonomously identifies control information, then the amount of control information required from WCD is reduced, but the complexity of the forwarding node increases
Solution Approach 1:
The patent extracts the control information selection function from the WCD and relocates it to the forwarding node. This extraction reduces the amount of control information that needs to be transmitted from the WCD, as the forwarding node independently determines the necessary control parameters based on its local observations and measurements.
Solution Approach 2:
The forwarding node is designed to perform multiple functions including signal forwarding, channel measurement, and autonomous control information selection. By consolidating these functions in a single node, the system reduces overall control signaling requirements while the forwarding node's enhanced capabilities are justified by the net reduction in network-wide complexity.
3Reliability
If the forwarding node operates in WCD-controlled mode, then communication errors are minimized, but network resource consumption increases
Solution Approach 1:
The forwarding node performs partial autonomous control by selecting only the most critical control information parameters autonomously, while still receiving guidance from the WCD for less critical parameters. This partial autonomy reduces network resource consumption compared to full WCD control, while maintaining sufficient communication accuracy for optimal performance.
