UE Beam Grouping for Neighbor Measurement Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in accurately reporting beam quality from neighboring nodes to a serving node due to limited reporting capabilities, leading to potential missed handover candidates and unstable network connections.
Innovation Solution
Implementing beam grouping methods at the user equipment (UE) to group detected beams based on beam grouping information, allowing for the reporting of aggregated measurement results per group rather than individual beams, and adjusting reporting frequency with thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UE reports quality for each individual beam from neighboring nodes, then measurement precision is improved, but device complexity increases due to limited reporting capabilities
Solution Approach 1:
The patent segments the reporting process by introducing beam grouping - beams are divided into groups based on their quality metrics, and reporting is performed at the group level rather than individual beam level. This segmentation reduces the number of reports needed while maintaining measurement precision through selective group-based reporting.
Solution Approach 2:
The patent applies partial action by reporting only the most relevant beam groups rather than all beams. The UE identifies beam groups that meet certain quality thresholds or have significant changes, and reports only those groups, reducing reporting overhead while maintaining necessary measurement precision for handover decisions.
2Device complexity
If maximum number of reported beams is limited, then device complexity is reduced, but loss of information increases as some neighboring nodes may not be included in measurement report
Solution Approach 1:
The patent merges multiple individual beam reports into consolidated beam group reports. By grouping beams that share common characteristics or belong to the same neighboring node, the system reduces the number of separate reports while preserving information about all beams through the group structure and aggregated quality metrics.
Solution Approach 2:
The patent introduces a new dimension of organization by grouping beams based on quality metrics and relationships rather than reporting them individually. This dimensional change from individual beam reporting to group-based reporting allows the system to convey information about multiple beams through a single report structure, reducing information loss while maintaining manageable complexity.
3Productivity
If reporting is triggered when any beam from neighboring node has better quality, then productivity is improved for timely handover notification, but stability worsens due to ping-pong effects when beams from same node are reported
Solution Approach 1:
The patent applies preliminary action by evaluating beam group quality before triggering reports. Instead of immediately reporting when any single beam improves, the system first assesses whether the improvement represents a significant change at the group level or indicates a genuine need for handover consideration. This preliminary evaluation filters out minor fluctuations that would cause ping-pong effects.
Solution Approach 2:
The patent implements feedback mechanisms where the reporting decision considers both current beam group quality and historical reporting patterns. The system monitors quality trends over time and adjusts reporting triggers based on whether improvements are sustained or transient, preventing unnecessary handovers while maintaining responsive notification for genuine quality improvements.

AI summary
Embodiments of the present disclosure relate to methods and network nodes and user equipment for measurement reporting. In example embodiments, a method implemented in a user equipment is provided. According to the method, the user equipment detects a plurality of beams from one or more of the UE's neighboring nodes, forms one measurement result of a group based on beam grouping information, and then send measurement report to the UE's serving node, including the measurement result of the group is included in the measurement report. According to the present disclosure, more neighboring nodes can be reported by the UE in a measurement report.
