Beam Management Reporting Activation for Low-Overhead Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beam management signaling frameworks in 5G networks are inadequate for supporting L1/L2-centric inter-cell mobility, leading to inefficiencies and increased signaling overhead due to the need for constant reporting of neighbor cells, especially when no neighbor cells are detected or their reference signals have inadequate quality.
Innovation Solution
A method and apparatus for activating beam management reporting configurations in user equipment (UE) to efficiently report neighbor cell measurements using low-overhead L1-signaling, allowing UE to trigger uplink signaling when specific reporting conditions are met, such as quality thresholds or beam failure instances, and dynamically adjust reporting configurations based on serving and non-serving cell conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If constant reporting of neighbor cells is implemented to support inter-cell mobility, then mobility support is improved, but signaling overhead increases
Solution Approach 1:
The patent implements dynamic beam management reporting configurations that adapt to current network conditions. The network can configure different reporting behaviors based on whether neighbor cells are detected and their quality levels, transitioning between continuous reporting and on-demand reporting modes to optimize the balance between mobility support and signaling overhead.
Solution Approach 2:
The patent changes the reporting parameters dynamically based on detection quality. When neighbor cells are not detected or quality is inadequate, the reporting configuration parameters are adjusted to reduce or suspend reporting, thereby reducing signaling overhead while maintaining mobility support when conditions improve.
2Loss of information
If beam management reporting is activated for all configurations, then reporting completeness is improved, but resource consumption increases
Solution Approach 1:
The patent applies partial action by activating beam management reporting only for specific configurations that are currently needed. Instead of maintaining all reporting configurations active simultaneously, the system selectively activates only those configurations relevant to current network conditions, reducing energy consumption while maintaining necessary reporting completeness.
Solution Approach 2:
The patent implements periodic activation and deactivation of reporting configurations based on triggering conditions. Rather than continuous operation, reporting is activated periodically when specific conditions are met (such as detecting neighbor cells above quality thresholds), reducing overall energy consumption while ensuring reporting completeness when needed.
3Productivity
If targeted beam management reporting is implemented, then signaling efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the UE autonomously determines which reporting configurations to activate based on pre-configured criteria and current measurements. The device itself manages the complexity of selecting and activating appropriate reporting configurations without requiring constant network intervention, thereby improving signaling efficiency while containing system complexity within reasonable bounds.

AI summary
Systems, methods, apparatuses, and computer program products for beam management (BM) reporting are provided. One method may include determining, at a UE, that reporting configuration(s) need to be activated, and providing, to a network, an indication to activate the reporting configuration(s).
