Terminal LOS Indicator Selection for Lower 6G Reporting Payload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of sub-THz frequencies for 6G communication systems results in a significant increase in payload size due to the reporting of multiple LOS-NLOS-Indicators, which is inefficient and resource-intensive.
Innovation Solution
A terminal is equipped with a control unit to measure and select indicator values based on quality, priority, or error tolerance, and a transmission unit to report a reduced number of indicators to the network, thereby optimizing the payload size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal measures and reports LOS-NLOS-Indicator using a plurality of frequencies, then the positioning accuracy is improved, but the payload size increases
Solution Approach 1:
The patent extracts only the necessary LOS-NLOS-Indicator values from multiple frequency measurements and reports them selectively. The terminal identifies which frequency measurements provide the most valuable positioning information and reports only those, rather than reporting all measurements. This extraction principle reduces payload size while maintaining positioning accuracy by filtering out redundant information.
Solution Approach 2:
The patent makes the reporting mechanism universal by allowing flexible selection of which indicator values to report based on different criteria (quality metrics, frequency priority, error tolerance). The same reporting framework can adapt to different positioning scenarios and requirements, making the system versatile for various positioning accuracy needs while controlling payload size.
2Loss of information
If the terminal reports all measured indicator values, then the information completeness is improved, but the resource efficiency deteriorates
Solution Approach 1:
The patent applies partial action by reporting only a subset of the measured indicator values rather than all of them. The terminal selectively reports indicator values that meet certain quality thresholds or are deemed most important for positioning, performing a partial reporting action that balances information completeness with resource efficiency. This avoids the excessive action of reporting every single measurement.
Solution Approach 2:
The patent changes the reporting parameters dynamically based on measurement quality, frequency priority, and error tolerance. Instead of a fixed reporting strategy, the system adjusts which parameters (indicator values) are reported based on current conditions, optimizing the balance between information completeness and resource efficiency for each reporting instance.

AI summary
A terminal includes: a control unit configured to measure a plurality of indicator values each indicating a line-of-sight state; and a transmission unit configured to select, on the basis of quality related to the indicator values, one or more of the plurality of indicator values measured by the control unit, and to report the selected one or more indicator values to a network.
