Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in performing accurate radio-based sensing operations due to limitations in measuring differential propagation paths, which affects the precision of sensing information obtained.
Innovation Solution
The method involves configuring a sensing configuration that includes indications of both a first and a second propagation path, allowing for the performance of differential sensing measurements. These measurements are then used to generate a sensing measurement report that indicates differences in measured values between the two paths, enabling more accurate sensing information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional single-path sensing measurements are used, then the measurement process is simple, but the sensing information accuracy is insufficient due to synchronization mismatches
Solution Approach 1:
The patent segments the sensing measurement process into multiple independent propagation path measurements. By measuring different propagation paths (e.g., direct path and reflected path) separately and comparing their differential characteristics, the system achieves higher sensing accuracy while maintaining manageable complexity through structured measurement procedures.
Solution Approach 2:
The patent introduces differential measurement as an intermediary technique that compares measurements from different propagation paths. This differential approach acts as a mediator that cancels out common errors and synchronization mismatches, thereby improving sensing accuracy without requiring completely new measurement systems.
2Reliability
If differential measurement based on multiple propagation paths is implemented, then sensing accuracy is improved by compensating for synchronization errors, but the measurement and processing complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the differential measurement results are fed back to compensate for synchronization mismatches. By continuously comparing and adjusting measurements from different propagation paths, the system improves reliability while managing complexity through iterative refinement processes.
Solution Approach 2:
The patent changes the measurement parameters by introducing differential characteristics (time difference, phase difference) between multiple propagation paths. This parameter transformation allows the system to maintain reliability through error compensation while handling complexity through standardized parameter comparison procedures.
