Dynamic CoMP Link Maintenance for Wireless Cell Edge Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CoMP link management systems fail to efficiently update and maintain network connectivity at cell edges, leading to unnecessary network resource overhead, unsuitable data rates, and redundant links, which can cause delays and inefficiencies in wireless data transmission.
Innovation Solution
A dynamic CoMP link maintenance system that identifies changes in data rate requirements and stale links, determines the need for link maintenance procedures such as handover, replacement, or scheme modification, and initiates these procedures using a hardware processor to optimize data rates and reduce overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CoMP links are established to improve network connectivity at cell edges, then network reliability is improved, but network overhead increases due to redundant links
Solution Approach 1:
The patent implements dynamic CoMP link maintenance where the system continuously monitors link quality metrics (RRC connection quality, data rate requirements) and adaptively activates or deactivates CoMP links based on current network conditions. This dynamic approach ensures links are maintained only when necessary, improving reliability while avoiding redundant link overhead.
Solution Approach 2:
The system changes operational parameters by detecting changes in data rate requirements and link quality metrics, then adjusts CoMP link status accordingly. When parameters indicate degraded connectivity, the system activates backup links; when parameters show improved conditions, the system deactivates redundant links, thus balancing reliability and overhead.
2Productivity
If CoMP link maintenance procedures are performed frequently to maintain optimal data rates, then data transmission performance is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback-driven maintenance system that monitors link quality metrics and data rate requirements, then triggers maintenance procedures only when performance thresholds are breached. This feedback mechanism optimizes data transmission performance by performing maintenance only when necessary, avoiding unnecessary system complexity from continuous monitoring and adjustment.
Solution Approach 2:
The system performs self-diagnosis by detecting stale links and changed data rate requirements autonomously, then initiates appropriate maintenance procedures without external intervention. This self-service approach improves productivity by maintaining optimal performance while reducing the complexity of external management.
3Reliability
If stale CoMP links are maintained to ensure continuous connectivity, then network reliability is improved, but resource efficiency decreases due to unnecessary resource allocation
Solution Approach 1:
The patent implements periodic assessment of CoMP link validity through detection of staleness based on RRC connection quality and data rate requirements. The system periodically evaluates whether maintained links are still necessary, terminating stale links to improve resource efficiency while maintaining connectivity through active links when needed.
Solution Approach 2:
The system discards stale CoMP links that no longer serve current data transmission needs, freeing associated network resources. When connectivity requirements change or new links become necessary, the system can recover and establish new CoMP links, thus maintaining reliability while improving resource efficiency by eliminating waste.

AI summary
This disclosure relates generally to improving wireless data rates, and more particularly to methods and systems for dynamic CoMP-link maintenance. In one embodiment, a system may identify a default coordinated multipoint set of neighboring base stations for a user equipment associated with a serving base station. The system may detect at least one of: a change in a data rate requirement for the user equipment, and a stale coordinated multipoint link for the user equipment to one of the neighboring stations in the default coordinated multipoint set. The system may also determine, after detecting at least one of the change in the data rate requirement and the stale coordinated multipoint link, whether to perform at least one coordinated multipoint link maintenance procedure, including at least one of: a coordinated multipoint link handover, a coordinated multipoint link replacement, a coordinated multipoint link consolidation, or a coordinated multipoint scheme modification.
