Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems, the method of counting pathloss estimations is not clear, leading to inappropriate pathloss estimation, which can lower throughput and deteriorate communication quality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the number of pathloss estimations is restricted without a clear counting method, then the system complexity is reduced, but pathloss estimation accuracy deteriorates
Solution Approach 1:
The patent segments the pathloss estimation process by defining distinct active duration periods for each pathloss reference signal. The terminal counts the number of active durations separately and applies different estimation methods based on the count value, creating a structured approach that balances complexity and accuracy.
Solution Approach 2:
The patent implements dynamic adaptation by changing the pathloss estimation method based on the counted number of active durations. When the count exceeds a threshold, the terminal switches to an alternative estimation approach, allowing the system to maintain accuracy under varying conditions without excessive complexity.
2Ease of operation
If pathloss estimation is performed without a clear counting method, then the ease of operation is improved, but communication quality deteriorates
Solution Approach 1:
The patent performs preliminary counting of active durations before executing pathloss estimation. By pre-determining the number of active reference signals, the terminal can select the appropriate estimation method in advance, ensuring both operational simplicity and reliable communication quality.
Solution Approach 2:
The patent incorporates feedback by using the counted number of active durations to adjust the estimation approach. The terminal continuously monitors the active duration count and adapts its estimation method accordingly, maintaining communication quality through automatic adjustment without complex manual configuration.
3Loss of time
If the number of active durations is not counted, then the processing time is reduced, but pathloss estimation accuracy deteriorates
Solution Approach 1:
The patent segments the time domain into distinct active duration periods for each pathloss reference signal. By counting these segmented periods, the terminal obtains accurate information about signal availability without requiring continuous monitoring, thus maintaining precision while limiting processing time overhead.
Solution Approach 2:
The patent applies partial action by counting only the necessary active durations required for accurate estimation rather than continuously monitoring all possible reference signals. This selective counting approach provides sufficient accuracy information without excessive processing time consumption.
