Auto Neighbor Relation Coordination via Master Base Station
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, there is a challenge in effectively managing auto neighbor relations between base stations to prevent simultaneous configuration of auto neighbor relations by base stations and ensuring that terminals do not perform operations beyond their capabilities, especially when CSI codebook information is not reported.
Innovation Solution
A method where a terminal configures and reports a default value for its capabilities, allowing for coordinated auto neighbor relation operations between base stations, and uses a mark to avoid simultaneous auto neighbor relation configurations, ensuring that the network understands the terminal's capabilities even without CSI codebook information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If base stations independently configure auto neighbor relations, then each base station can autonomously manage its neighbor relations, but simultaneous configuration occurs causing conflicts and errors
Solution Approach 1:
The patent merges the autonomous ANR configuration capabilities of multiple base stations into a coordinated system. The master base station consolidates ANR configuration requests from multiple slave base stations and manages terminal ANR operations centrally, preventing simultaneous configurations while maintaining autonomous management benefits.
Solution Approach 2:
The master base station acts as an intermediary between slave base stations and the terminal for ANR operations. It receives ANR requests from slave base stations, coordinates the timing and execution, and ensures only one base station configures ANR at a time, thereby preventing conflicts.
2Productivity
If terminals perform ANR operations without capability verification, then ANR can be configured quickly, but terminals may perform operations beyond their capabilities causing errors
Solution Approach 1:
The system performs preliminary capability verification by obtaining terminal ANR capability information before configuring ANR operations. The master base station checks whether the terminal supports ANR functionality and appropriately configures measurement parameters based on terminal capabilities, preventing operations beyond terminal capabilities.
3Loss of information
If CSI codebook information is not reported, then the network cannot understand terminal capabilities for MIMO functions, but requiring reporting increases complexity
Solution Approach 1:
The terminal autonomously determines and applies appropriate default values for CSI codebook configuration when specific capability information is not reported. This self-service approach allows the network to understand terminal capabilities through actual behavior rather than explicit reporting, reducing signaling overhead while maintaining information accuracy.
