Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultra-wideband (UWB) devices face challenges in configuring multiple functionalities such as ranging, data communication, and time difference of arrival (TDoA) due to limited configurability and reserved bits, especially for non-ranging applications, which restricts their adaptability and future-proofing.
Innovation Solution
A control information element (IE) is generated by a first wireless communication device to configure UWB transmissions between devices, including fields for indicating the presence of specific functionalities like ranging, data communication, sensing, and TDoA, allowing for adaptable and future-proof UWB configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single control IE is used to configure multiple UWB functionalities, then the adaptability and versatility of UWB systems are improved, but the device complexity increases due to the need to manage multiple functionalities within a unified structure
Solution Approach 1:
The control IE is segmented into distinct functional fields, each responsible for configuring a specific UWB functionality (ranging, sensing, data communication, TDoA). This segmentation allows the system to maintain a unified control structure while managing multiple functionalities through organized, modular fields within the IE.
Solution Approach 2:
The control IE is designed as a universal configuration structure that can accommodate multiple UWB functionalities simultaneously. By incorporating multiple functional fields within a single IE, the system achieves multi-functionality without requiring separate control structures for each functionality, thereby improving adaptability while controlling complexity.
2Device complexity
If multiple separate IEs are used for each UWB functionality, then the device complexity is reduced and each functionality can be configured independently, but the loss of information increases due to the need for multiple separate configuration messages
Solution Approach 1:
Multiple functionality-specific configuration fields are merged into a single control IE structure. This consolidation ensures that all UWB functionality configurations are transmitted together in one message, preventing information fragmentation and reducing the need for multiple separate configuration exchanges between devices.
3Adaptability or versatility
If reserved bits are allocated for future functionalities, then the adaptability for future applications is improved, but the loss of substance increases due to the consumption of configuration space that cannot be currently utilized
Solution Approach 1:
The control IE structure is designed in advance to include extensible fields and reserved capacity for future functionalities. This preliminary structuring allows the system to accommodate emerging UWB applications without requiring fundamental changes to the configuration protocol, while currently utilizing only the necessary configuration space.
