UE-Initiated Beam Reporting for Timely Beam Quality Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing beam reporting, leading to high overhead and potential performance degradation due to outdated beam information, as traditional network-controlled beam reporting methods do not leverage the UE's timely knowledge of beam quality changes.
Innovation Solution
Implementing UE-initiated beam reporting procedures that allow the user equipment (UE) to trigger beam reporting based on event-driven conditions, reducing unnecessary reporting overhead and latency by enabling the UE to proactively manage beam quality assessments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network-controlled beam reporting is used, then beam management is centralized, but reporting overhead increases and beam information becomes outdated
Solution Approach 1:
The patent inverts the traditional network-controlled beam reporting model by enabling UE-initiated beam reporting. The UE autonomously triggers beam reports based on local beam quality assessments, reversing the control flow from network-driven to UE-driven. This inversion allows the UE to proactively provide timely beam information without waiting for network commands, thereby reducing latency and improving information accuracy.
Solution Approach 2:
The UE performs self-service by autonomously assessing beam quality and triggering reports based on its own measurements and configured events. The UE independently determines when beam reporting is necessary based on local conditions (e.g., beam quality thresholds, event triggers), eliminating the need for continuous network control and reducing overhead while maintaining timely information availability.
2Reliability
If frequent beam reporting is implemented, then beam quality is updated timely, but reporting overhead increases
Solution Approach 1:
The patent implements periodic action through event-triggered reporting mechanisms. Instead of continuous or frequent reporting, the UE monitors configured events (such as beam quality threshold crossings, mobility conditions, or network requests) and triggers reports only when these events occur. This periodic, event-driven approach ensures beam quality information remains fresh when needed while significantly reducing unnecessary reporting overhead and energy consumption.
Solution Approach 2:
The system dynamically adjusts reporting parameters based on changing conditions. The UE modifies reporting behavior according to parameters such as beam quality thresholds, event triggers, and network configurations. When beam quality is stable and no events are triggered, reporting is minimized or suspended. When parameters change (e.g., beam degradation detected or event triggered), reporting activates or intensifies, optimizing the balance between information freshness and overhead reduction.
3Loss of energy
If UE-initiated beam reporting is enabled, then reporting overhead is reduced, but configuration complexity increases
Solution Approach 1:
The patent segments the beam reporting configuration into distinct, manageable components. Report configurations are divided into separate parameters including event conditions, trigger states, PUCCH resources, and priority settings. This segmentation allows the UE to process and manage configuration elements independently, reducing the cognitive load and simplifying the overall configuration complexity while enabling flexible UE-initiated reporting.
Solution Approach 2:
The network performs preliminary action by pre-configuring the UE with report configurations, trigger states, and associated PUCCH resources before beam reporting begins. The UE stores and prepares these configurations in advance, so when beam reporting is needed, the UE can immediately use the pre-configured parameters without requiring complex real-time configuration decisions. This preliminary setup reduces operational complexity while enabling autonomous UE-initiated reporting.
4Adaptability or versatility
If multiple report configurations are managed, then beam management flexibility increases, but processing complexity increases
Solution Approach 1:
The patent merges multiple report configurations into a unified management framework. The UE consolidates multiple report configurations (including event-triggered and non-event-triggered types) into a single manageable structure with associated trigger states and PUCCH resources. This merging approach allows the UE to handle multiple reporting scenarios through a standardized process, reducing processing complexity while maintaining the flexibility to manage diverse beam reporting needs.
