Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If antenna and cell resource are fixedly associated with each other, then base station configuration is simple and stable, but load distribution becomes imbalanced and throughput decreases
Solution Approach 1:
The patent implements dynamic association between antennas and cell resources by introducing a control unit that reallocates cell resources to different antennas based on real-time load information. This allows the system to transition from a static fixed association to a dynamic adaptive association, resolving the contradiction between stability and throughput by maintaining operational flexibility while achieving load balance.
Solution Approach 2:
The patent employs a feedback mechanism where load information from multiple antennas is continuously monitored and fed back to the control unit. The control unit uses this feedback to make intelligent decisions about cell resource allocation, adjusting the association dynamically to prevent load imbalance and maintain optimal throughput while preserving system stability through controlled adaptation.
2Ease of operation
If one cell resource is copied and distributed to multiple antennas, then resource control across areas is improved, but resource control across multiple cell resources remains impossible
Solution Approach 1:
The control unit serves as a universal management entity that handles multiple cell resources simultaneously. Instead of copying and distributing individual cell resources to antennas, the control unit provides centralized multi-cell resource control capabilities, enabling flexible allocation across multiple cell resources and antennas based on overall system load conditions, thus achieving both ease of operation and adaptability.
Solution Approach 2:
The control unit acts as an intermediary between multiple cell resources and multiple antennas. It receives load information from antennas, processes this information against multiple cell resources, and makes intelligent allocation decisions. This intermediary approach enables comprehensive multi-cell resource control while maintaining operational simplicity through centralized management.
3Area of stationary object
If distributed antenna system is used to expand communication area, then connectivity is improved, but load imbalance across signal processing units occurs
Solution Approach 1:
The system implements feedback control by continuously monitoring load information from each signal processing unit and antenna. The control unit uses this feedback to detect load imbalance conditions and trigger reallocation of cell resources to maintain reliable load balance across all signal processing units, ensuring system reliability while maintaining expanded communication coverage.
Solution Approach 2:
The patent enables dynamic reallocation of cell resources between antennas and signal processing units based on real-time load conditions. This dynamic adjustment mechanism allows the system to maintain reliable load balance across distributed signal processing units while preserving the expanded communication area benefits of the distributed antenna architecture.
