Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high reporting overhead in beam management due to the need to report a large number of beam indexes in new radio systems, particularly in high-frequency scenarios, leads to inefficient communication.
Innovation Solution
Implementing a method for partial reporting of reference signal resource indexes and mapping measurement results in a specific order to reduce the reporting overhead, including techniques such as selecting and transmitting partial reference signal resources, their indexes, and mapping differences in a defined order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all reference signal resource indexes are reported in beam management, then complete beam information is provided to the base station, but reporting overhead increases significantly
Solution Approach 1:
The patent extracts and reports only the most relevant beam information (top-K beams with best L1-RSRP) instead of all beam indexes. This selective extraction reduces the quantity of reported data while maintaining the essential information needed for beam management, directly resolving the contradiction between information completeness and reporting overhead.
Solution Approach 2:
The patent implements partial reporting by transmitting only a subset of reference signal resource indexes (specifically the top-K best beams) rather than all available beams. This partial action approach provides sufficient beam management information to the base station while significantly reducing feedback overhead, effectively balancing information completeness with reporting efficiency.
2Measurement precision
If measurement results for all reference signal resources are reported, then comprehensive channel state information is obtained, but feedback load increases
Solution Approach 1:
The patent applies local quality by differentiating the reporting treatment of different reference signal resources. Instead of uniform reporting of all measurement results, it selectively reports measurement results based on their quality (L1-RSRP values), reporting only the top-K best measurements with highest precision relevance. This resolves the contradiction by maintaining measurement precision for critical beams while reducing overall feedback load.
Solution Approach 2:
The patent implements partial reporting of measurement results by transmitting only the top-K measurement values corresponding to the best beams rather than all measurement results. This partial action provides sufficient channel state information for effective beam management while significantly reducing the feedback load, directly addressing the contradiction between measurement precision and feedback quantity.
3Reliability
If beam management is performed in high-frequency scenarios with path loss compensation, then communication reliability improves, but the number of beams to report increases
Solution Approach 1:
The patent extracts only the essential beam management information (top-K beam indexes and their measurement results) needed for reliable high-frequency communication, eliminating the need to report all beam data. This extraction approach maintains communication reliability by providing sufficient beam alignment information while reducing the complexity of beam management through decreased feedback processing requirements.
Solution Approach 2:
The patent applies partial reporting by transmitting only a subset of beam management information (top-K beams) rather than complete beam sets. This partial action reduces beam management complexity and feedback overhead while maintaining sufficient information for reliable beam alignment in high-frequency scenarios, effectively resolving the contradiction between reliability and system complexity.
