Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional base station layout methods face challenges such as high mutual interference between base stations using same-frequency networking, complexity in implementing different-frequency networking, and inability to adapt to dynamic changes in hotspot areas, leading to excessive or inadequate coverage.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If base stations use same-frequency networking to achieve coverage, then coverage is provided, but mutual interference between base stations increases
Solution Approach 1:
The patent implements dynamic layout of micro cells that can move and adjust their positions based on real-time user distribution and network conditions. The micro cells dynamically adjust their coverage areas and frequencies to avoid fixed interference patterns, transforming the static base station layout into a dynamic adaptive system that reduces mutual interference while maintaining coverage.
Solution Approach 2:
The patent changes the operational parameters of micro cells by allowing them to switch between different frequency bands and adjust their coverage radii based on user density and interference conditions. This parameter flexibility enables the system to optimize between coverage area and interference reduction dynamically.
2Device complexity
If fixed layout method is used for base stations, then layout is simple, but adaptability to dynamic changes in hotspot areas is poor
Solution Approach 1:
The patent transforms the fixed base station layout into a dynamic system where micro cells can autonomously move, appear, and disappear based on real-time user distribution. The layout complexity is managed through automated scheduling and coordination mechanisms that simplify the dynamic adjustment process while maintaining high adaptability to changing hotspot areas.
Solution Approach 2:
The micro cells perform self-organization and self-adjustment based on detected user distribution and network conditions. The system automatically determines optimal positions and frequencies without requiring complex manual reconfiguration, enabling the layout to adapt dynamically while keeping the control mechanism relatively simple.
3Productivity
If more micro cells are deployed to increase network capacity, then network capacity increases, but system complexity increases
Solution Approach 1:
The patent merges multiple micro cells into a coordinated network where cells share resources and work together to serve users. Instead of independent operation that would increase complexity, the micro cells are integrated through centralized scheduling that manages coordination, allowing increased capacity through cooperation rather than independent scaling.
Solution Approach 2:
The micro cells are designed with multi-functionality to perform various tasks including coverage provision, capacity enhancement, and interference avoidance. This universal design allows a single micro cell type to handle multiple network requirements, reducing the need for specialized cells and thereby limiting the increase in system complexity despite increased capacity.
