Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full device addresses are included in scheduling information elements, then device identification accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the necessary identification information from full device addresses by using bitmaps to indicate locations of parameter configuration information in device parameter lists. Instead of transmitting complete device addresses, the system transmits compact bitmap indicators that point to relevant parameters, thereby reducing signaling overhead while maintaining identification capability.
Solution Approach 2:
The patent creates a compressed representation (copy) of device identification information through bitmaps. These bitmaps serve as surrogate indicators that reference actual device parameters without requiring the full device address data, enabling efficient identification with reduced signaling requirements.
2Quantity of substance
If device addresses are omitted in list elements, then signaling overhead is reduced, but information completeness may be compromised
Solution Approach 1:
The patent introduces bitmaps as intermediary elements that mediate between device addresses and parameter configuration information. These bitmaps serve as references that indirectly point to device parameters in predefined lists, allowing the system to omit full device addresses while preserving the ability to identify and access specific device information through the bitmap indicators.
Solution Approach 2:
The patent performs preliminary organization of device parameter information into structured lists with predefined locations. By pre-arranging parameters in device parameter lists and assigning them specific positions, the system enables subsequent reference through bitmaps without needing to transmit complete device addresses, thus reducing overhead while maintaining information accessibility.

AI summary
This application discloses a communication method for a UWB and a related product. This application can be applied to a UWB-based wireless personal area network system, a sensing system, a positioning system, a ranging system, or a communication system, and can be further applied to a wireless local area network system that supports 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11be or Wi-Fi 7, and a next-generation protocol of 802.11be, for example, Wi-Fi 8. The method includes: generating a first message including a first bitmap, where an ith bit in the first bitmap corresponds to an ith UWB device, and when the ith bit is set to a specified value, the ith bit indicates a location of parameter configuration information of the ith UWB device in a first DPL; and sending the first message.
