Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently predicting beam quality due to lack of awareness about network configurations, such as precoders and power settings, which hinders effective channel prediction and increases measurement overhead.
Innovation Solution
Introduce a network configuration identifier (NW configuration ID) to assist User Equipment (UE) in building an AI/ML model for predicting channel quality, reducing the need for explicit measurements and maintaining beam management efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UE performs explicit beam quality measurements, then measurement precision is improved, but measurement overhead and energy consumption increase
Solution Approach 1:
The patent introduces network configuration identifiers (NW configuration IDs) as intermediary elements that carry implicit beam configuration information. Instead of requiring UE to perform explicit measurements of beam quality, the NW configuration ID serves as a mediator that enables UE to infer beam quality information from network-side configuration data, thereby reducing measurement overhead while maintaining sufficient measurement precision for beam management decisions
Solution Approach 2:
The patent creates a simplified copy of beam configuration information through the NW configuration ID. Rather than transmitting complete beam quality measurement data or requiring full measurement procedures, the system generates a condensed identifier that captures essential beam configuration characteristics, allowing UE to derive necessary beam quality information without performing exhaustive measurements
2Measurement precision
If UE performs explicit beam quality measurements, then measurement precision is improved, but energy consumption increases
Solution Approach 1:
The NW configuration ID acts as an energy-efficient intermediary that enables UE to obtain beam quality information without activating full measurement procedures. By deriving beam quality inference from network configuration data rather than performing active signal measurements, the system significantly reduces UE energy consumption while maintaining adequate measurement precision for beam management
Solution Approach 2:
The system enables UE to self-determine beam quality information by utilizing the NW configuration ID that contains embedded configuration data. Instead of requiring UE to actively measure and process extensive signal characteristics, the UE can self-service by interpreting the configuration identifier, thereby reducing energy consumption while maintaining measurement capability
3Measurement precision
If network provides detailed beam configuration information, then beam prediction accuracy is improved, but network information exposure increases
Solution Approach 1:
The patent extracts only the essential configuration information needed for beam prediction and encapsulates it within the NW configuration ID. By taking out only the necessary bits of configuration data rather than transmitting complete network state information, the system achieves sufficient beam prediction accuracy while minimizing network information exposure to UE
Solution Approach 2:
The NW configuration ID functions as a disposable information carrier that provides sufficient beam configuration data for prediction purposes without requiring persistent or extensive information storage. The identifier contains just enough information for the prediction function and can be discarded after use, avoiding the need to expose or store detailed network configuration information
