5G NR Beam Reporting Configuration for Uplink Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high payload and latency in 5G NR systems due to large-scale beam management are exacerbated by the need to measure and report a large number of beams, which overwhelms the limited uplink channel resources and requires inefficient data updates for AI model training and inference.
Innovation Solution
Implementing an information transceiving method and apparatus that configures terminal equipment with specific reporting configurations, including a reduced number of measurement results, relevant reference signal sets, and time intervals for aperiodic reporting, allowing partial and time-divided feedback to manage uplink load effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all M*N beams are measured and reported in existing standards, then complete beam measurement coverage is achieved, but system payload and latency are greatly increased
Solution Approach 1:
The patent segments the complete beam measurement process into two parts: (1) AI model predicts a subset of candidate beams from all M*N beams, and (2) terminal equipment measures and reports only these candidate beams. This segmentation reduces the measurement payload while maintaining coverage quality through intelligent selection.
Solution Approach 2:
The patent introduces an AI model as an intermediary between the complete beam set and the measurement process. The AI model processes the full beam information and outputs a reduced candidate set, acting as a mediator that filters and prioritizes beams before terminal measurement, thereby reducing payload.
2Measurement precision
If all M*N beams are measured and reported in existing standards, then complete beam measurement coverage is achieved, but latency is greatly increased
Solution Approach 1:
The patent segments the measurement process to measure only AI-predicted candidate beams instead of all M*N beams. This time segmentation reduces the total measurement duration while maintaining coverage effectiveness through intelligent beam selection.
Solution Approach 2:
The patent applies preliminary action by using the AI model to predict and identify candidate beams before the terminal equipment performs measurement. This pre-processing step filters out unnecessary beams in advance, reducing the actual measurement time and latency.
3Loss of information
If a large number of measurement results are reported via uplink channels, then complete measurement data is provided for AI model training, but uplink channel resources are overwhelmed
Solution Approach 1:
The patent extracts only the essential measurement data from the complete M*N beam set by having the terminal measure and report results only for AI-predicted candidate beams. This extraction provides sufficient training data for the AI model while keeping uplink channel load manageable.
Solution Approach 2:
The patent applies partial action by measuring and reporting only a subset of candidate beams rather than all beams. This partial measurement approach provides adequate data for AI model training and inference without overwhelming the uplink channel resources.
4Reliability
If measurement reporting is performed frequently to update AI model data, then model accuracy is maintained, but uplink channel resources are consumed
Solution Approach 1:
The patent implements periodic action by configuring the terminal to perform measurement reporting at specific time intervals rather than continuously. This periodic reporting maintains model accuracy by providing updated data at appropriate frequencies while conserving uplink channel resources and reducing energy consumption.
