Adaptive Channel Measurement Reporting for AI Positioning Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AI positioning technologies face high reporting overheads in channel measurement reports due to the lack of consideration for varying impacts of different channel measurement results on positioning performance, leading to redundant reporting.
Innovation Solution
Implement a flexible payload format for channel measurement reports by adjusting the payload size based on positioning accuracy requirements and channel conditions, using adaptive indication information to reduce reporting overheads while maintaining accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all channel measurement results are reported using a fixed payload format, then positioning accuracy can be maintained, but reporting overheads increase significantly
Solution Approach 1:
The patent applies dynamics by making the payload format adjustable and adaptive rather than fixed. The network element can dynamically select different payload formats (first, second, or third format) based on channel conditions and positioning accuracy requirements, allowing the reporting mechanism to adapt its complexity to the actual needs of each scenario.
Solution Approach 2:
The patent changes the parameter of payload format structure based on channel conditions. By modifying parameters such as whether to report all paths or only significant paths, and adjusting the level of detail in path information, the system optimizes the balance between reporting overhead and positioning accuracy for different channel environments.
2Ease of manufacture
If a fixed payload format is used for channel measurement reports, then implementation is simple, but reporting overheads are high due to redundant information
Solution Approach 1:
The system transitions from a static fixed format to a dynamic adaptive format selection mechanism. The network element evaluates channel conditions and positioning requirements to determine the appropriate payload format, achieving both implementation feasibility and overhead reduction through conditional format selection.
Solution Approach 2:
Different payload formats are applied to different channel conditions and positioning scenarios. Rather than using a uniform format everywhere, the system applies the appropriate level of detail locally - using compact formats when full precision is not needed and detailed formats when accuracy requirements demand it.
3Measurement precision
If detailed path information is reported for all channels, then positioning accuracy is maintained, but reporting overheads increase
Solution Approach 1:
The patent changes the parameter of information detail level in the payload based on channel conditions. In good channel conditions where fewer paths are needed for accurate positioning, the payload reports only significant paths with reduced detail. In poor channel conditions, the payload expands to include more paths and detailed information to maintain positioning accuracy.
Solution Approach 2:
The patent extracts and reports only the most significant path information when channel conditions permit, rather than reporting all path details unconditionally. By identifying and reporting only the critical paths that contribute most to positioning accuracy, the system reduces payload size while maintaining sufficient positioning performance.
Data Source
AI summary
A method may be applied to an AI positioning scenario, a location management function network element determines, based on different positioning accuracy requirements, information related to a payload size of a channel measurement report, and indicates, to the channel measurement network element, the information related to the payload size; or the channel measurement network element obtains information about a positioning accuracy requirement from the location management function network element, and determines, based on the positioning accuracy requirement and a feature of the channel measurement result, information related to a payload size of a channel measurement report.
