Beam Prediction Reporting With Top-K Beam Identifier Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies and increased latency due to unnecessary signaling and reporting of predicted measurement results, such as RSRP/SINR, which are not beneficial from the network's perspective.
Innovation Solution
The proposed solution involves configuring user equipment (UE) with measurement reporting parameters that identify a set of beam prediction resources and a reporting scheme, allowing the UE to transmit only the top K resource identifiers of beams with the strongest predicted measurement results, thereby reducing unnecessary signaling by reporting resource identifiers associated with a subset of beams that satisfy a performance threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the UE reports predicted measurement results (RSRP/SINR) for all beams, then the network receives complete beam performance information, but the signaling overhead increases and latency increases
Solution Approach 1:
The patent extracts only the essential information (beam identifier and predicted measurement result) from the complete beam performance data and reports only for beams that satisfy the performance threshold. This selective extraction reduces signaling overhead and latency while maintaining the network's ability to identify the best beams for communication.
Solution Approach 2:
Instead of reporting all beam measurements (excessive action), the patent applies partial action by reporting only the top K beams or beams exceeding a threshold. This partial reporting approach reduces the quantity of signaled information while still providing sufficient data for beam selection decisions.
2Loss of information
If the UE reports all beam measurement results, then the network has complete data for beam selection, but the signaling overhead increases
Solution Approach 1:
The patent extracts only the necessary beam identification information and predicted measurement results for beams meeting the performance threshold, omitting unnecessary measurement data for beams that do not meet the threshold. This selective extraction reduces signaling overhead while preserving the information needed for effective beam selection.
Solution Approach 2:
The patent implements partial reporting by transmitting measurement results only for the top K beams or beams exceeding a predefined threshold, rather than reporting all beam measurements. This reduces the quantity of signaled data while maintaining sufficient information for network beam selection decisions.
3Loss of information
If the UE reports predicted measurement results for all beams, then the network receives comprehensive beam data, but the processing time and latency increase
Solution Approach 1:
The patent extracts only the essential beam identification and performance prediction data for beams satisfying the threshold, removing unnecessary measurement results. This reduces the data volume that needs to be processed, thereby improving beam selection efficiency and reducing latency.
Solution Approach 2:
The patent applies partial reporting by transmitting only the top K beam measurements or those exceeding a threshold, rather than all beam data. This reduces the processing burden on the network while maintaining the data needed for efficient beam selection, thus improving productivity.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a signal indicating measurement reporting parameters for the UE, the measurement reporting parameters identifying a set of beam prediction resources for a set of beams and a beam measurement reporting scheme. The UE may transmit a beam measurement report indicating beam resource identifiers associated with a subset of beams from the set of beams, each beam in the subset of beams satisfying a performance threshold for corresponding beam prediction resources in the set of beam prediction resources associated with the measurement reporting parameters, wherein the beam resource identifiers of beams in the subset of beams are based at least in part on the beam measurement reporting scheme.
