Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CoMP link mechanisms do not provide optimization at an individual user device (UE) level, leading to inefficient resource management and outdated link formations, which can result in suboptimal service quality and resource utilization at cell edges.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CoMP links are established to improve network performance at cell edges, then service quality and connectivity are improved, but resource utilization efficiency deteriorates due to outdated link formations and lack of optimization
Solution Approach 1:
The patent implements dynamic CoMP link maintenance by continuously monitoring link conditions and automatically adjusting link configurations. The system transitions from static, pre-configured CoMP links to dynamic links that adapt to changing network conditions, user movements, and resource availability, thereby maintaining service quality while optimizing resource utilization.
Solution Approach 2:
The patent employs feedback mechanisms by monitoring link throughput, resource utilization metrics, and trigger conditions. Based on this feedback, the system determines whether to maintain, modify, or terminate CoMP links, creating a closed-loop control system that optimizes resource usage while preserving service quality.
2Productivity
If dynamic CoMP link maintenance is implemented to optimize resource utilization, then resource efficiency improves, but system complexity increases due to additional monitoring and decision-making processes
Solution Approach 1:
The patent implements self-service mechanisms where the system automatically monitors link conditions, evaluates maintenance needs, and executes link configuration changes without external intervention. The eNodeB autonomously makes decisions about CoMP link maintenance based on predefined criteria and real-time measurements, reducing the need for complex external control systems.
Solution Approach 2:
The patent replaces manual or centralized control mechanisms with automated algorithmic decision-making. Instead of relying on complex mechanical or procedural systems for link management, the invention uses software-based algorithms that automatically evaluate link conditions and determine maintenance actions, simplifying the overall system architecture.
3Reliability
If CoMP links are maintained for all user equipment, then service quality is preserved, but resource consumption increases due to inactive links and lack of termination mechanisms
Solution Approach 1:
The patent implements mechanisms to discard inactive or unnecessary CoMP links and recover the resources they occupy. By continuously evaluating link utility and terminating links that no longer serve active users or meet performance thresholds, the system releases radio resources, processing power, and memory for reuse, thereby reducing overall resource consumption while maintaining service quality for active users.
Solution Approach 2:
The patent changes the operational parameters of CoMP links dynamically based on user activity and network conditions. Links are activated or deactivated, and their configuration parameters are adjusted according to real-time measurements, ensuring that resources are allocated only when and where needed, thus reducing waste while preserving service quality.
