Base Station Load Information for Interference Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accurately managing resource allocation and interference coordination across overlapping coverage areas in dense deployments of cells, such as small cells, due to limited information exchange and lack of specific load indications tailored to individual neighboring base stations.
Innovation Solution
A method where base stations determine and share load information specific to areas of shared coverage with neighboring stations, allowing for optimized resource usage and interference coordination by transmitting tailored load data, including information on UE location and resource usage, to enable accurate scheduling decisions and avoid interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If base stations share general load information, then information exchange is simplified, but resource allocation accuracy and interference coordination effectiveness deteriorate
Solution Approach 1:
The patent applies local quality by providing base stations with load information specific to their individual neighboring cells rather than general network-wide load data. Each base station receives tailored load indications that reflect the actual conditions in their specific overlapping coverage areas, enabling accurate resource allocation and interference coordination while maintaining manageable information exchange complexity through targeted communication.
2Measurement precision
If base stations exchange detailed load information for each neighboring cell, then resource allocation accuracy improves, but system complexity increases
Solution Approach 1:
The patent segments the network into individual base station entities, each managing its own resource allocation independently based on received load information. The segmentation of information exchange occurs at the cell level, where each base station only processes and acts on load indications relevant to its specific neighboring cells, avoiding the complexity of processing comprehensive network-wide data while maintaining high accuracy for local resource management.
3Productivity
If cells are deployed densely to increase capacity, then network coverage and capacity improve, but overlapping coverage areas and interference increase
Solution Approach 1:
The patent implements feedback mechanisms where base stations continuously exchange load information with their neighbors based on actual user equipment conditions. This feedback loop enables dynamic adjustment of resource allocation in overlapping coverage areas, allowing the system to adapt to changing interference conditions and maintain high capacity while managing interference through real-time coordination rather than static deployment configurations.
