Terminal LOS Indicator Reporting for Sub-THz Payload Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of sub-THz frequencies for 6G communication systems leads to an 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 selectively report a reduced number of LOS-NLOS-Indicators based on quality, priority, timer-based reception, allowable error, or a combination of these criteria to manage 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 positioning accuracy is improved, but payload size increases
Solution Approach 1:
The patent extracts only the necessary LOS-NLOS-Indicator values from multiple frequency measurements for reporting. Instead of reporting all measured indicator values across multiple frequencies, the system selectively reports only those indicators that are necessary for maintaining positioning accuracy, thereby reducing payload size while preserving essential positioning information
Solution Approach 2:
The system performs partial action by reporting a subset of measured indicator values rather than all of them. The terminal measures indicators at multiple frequencies but reports only a portion of these measurements to the network, achieving sufficient positioning accuracy with reduced reporting overhead
2Measurement precision
If the terminal reports multiple LOS-NLOS-Indicators for sub-THz frequencies, then line-of-sight detection accuracy is improved, but resource efficiency deteriorates
Solution Approach 1:
The system changes the parameter of indicator reporting by introducing selective reporting based on measured indicator values and predetermined thresholds. Instead of uniformly reporting all indicators, the system dynamically determines which indicators to report based on their values and the allowable error, optimizing resource usage while maintaining detection accuracy
Solution Approach 2:
The reporting mechanism is made dynamic by allowing the terminal to selectively report indicators based on current measurement conditions. The system adapts the number and type of reported indicators according to the measured values and their relevance to positioning accuracy, rather than using a static reporting scheme

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, on the basis of a size of a difference among the plurality of indicator values measured by the control unit and an allowable error, to select one or more of the plurality of indicator values and to report the selected one or more indicator values to a network.
