UWB Measurement Reporting with Segmented Results for Duty-Cycle Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UWB systems face increased narrowband signal consumption and energy consumption due to the need to include all types of measurement results in a single measurement report message, which is inefficient and energy-intensive.
Innovation Solution
The method involves indicating the type of measurement result in the information transmission, allowing different types of measurement results to be transmitted via separate messages, reducing narrowband signal consumption and energy usage by optimizing the duty cycle requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all types of measurement results are included in a single measurement report message, then complete measurement information is transmitted, but narrowband signal consumption and energy consumption increase
Solution Approach 1:
The measurement report message is segmented into multiple parts, with each part containing a specific type of measurement result (e.g., ranging results, positioning results, sensing results). This segmentation allows the system to transmit only the required measurement information types, reducing unnecessary narrowband signal consumption while maintaining information completeness.
Solution Approach 2:
The system dynamically selects which measurement result types to include in each measurement report message based on actual measurement needs and duty cycle requirements. This dynamic adaptation allows the system to optimize narrowband signal consumption by transmitting only necessary information at each moment, rather than always transmitting all measurement results.
2Loss of information
If all types of measurement results are included in a single measurement report message, then complete measurement information is transmitted, but energy consumption of receiving and processing increases
Solution Approach 1:
By segmenting measurement results into different message types, the receiving device can selectively process only the relevant measurement information (e.g., only ranging results or only positioning results) based on its current operational needs, thereby reducing processing energy consumption while maintaining access to complete measurement information when required.
Solution Approach 2:
The receiving device dynamically adjusts its processing behavior based on the type of measurement report message received and its current duty cycle state, enabling energy-efficient processing by focusing computational resources on relevant measurement data rather than processing all measurement results uniformly.
3Loss of information
If narrowband signal transmission is increased to include all measurement results, then measurement information completeness is improved, but duty cycle requirements are violated
Solution Approach 1:
Measurement report messages are segmented into multiple transmission opportunities, with each segment containing specific measurement result types. This allows the system to distribute the transmission of complete measurement information across multiple duty cycle-compliant transmission windows, ensuring both information completeness and duty cycle adherence.
Solution Approach 2:
The system dynamically determines the content and timing of measurement report transmissions based on duty cycle constraints, selecting which measurement result types to transmit in each message to ensure compliance with narrowband signal duty cycle requirements while progressively conveying complete measurement information.
