Facing-Sector Resource Block Assignment for Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interference occurs in wireless communication networks when nearby base stations allocate conflicting resource blocks to user devices, leading to reduced network performance.
Innovation Solution
A controller dynamically assigns resource blocks to facing sectors of base stations based on performance data to maximize allocation and minimize interference, using a system with processors and memory to continuously update assignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base stations allocate resource blocks to user devices in nearby cells independently, then resource block allocation efficiency is improved, but interference between nearby base stations increases
Solution Approach 1:
A controller is introduced as an intermediary between base stations to coordinate resource block assignments. The controller receives resource block assignment information from multiple base stations, determines facing sectors, and adjusts assignments to avoid conflicts between facing sectors while maintaining high allocation efficiency.
Solution Approach 2:
The system implements feedback mechanisms where base stations report resource block assignment information to the controller, which then adjusts assignments based on interference conditions. The controller continuously monitors and reassigns resource blocks to optimize performance while minimizing interference.
2Object-affected harmful factors
If resource blocks are statically assigned to facing sectors, then interference is reduced, but resource block utilization efficiency decreases
Solution Approach 1:
The system dynamically adjusts resource block assignments to facing sectors based on current network conditions and traffic demands. The controller continuously monitors resource block usage and interference levels, reassigning resource blocks in real-time to optimize both interference reduction and utilization efficiency.
Solution Approach 2:
The controller changes the assignment parameters of resource blocks based on detected interference conditions. When facing sectors are identified, the controller modifies resource block assignments to avoid conflicts, adjusting the allocation dynamically rather than using fixed static assignments.
3Reliability
If a controller dynamically assigns resource blocks to facing sectors, then interference is minimized and network performance improves, but system complexity increases
Solution Approach 1:
The controller performs multiple functions including receiving resource block assignment information from base stations, determining facing sectors, adjusting resource block assignments, and coordinating between multiple base stations. This multi-functionality consolidates complexity into a single centralized component rather than distributing it across multiple base stations.

AI summary
A wireless communication network includes base stations serving cells. A first sector of a first cell served by a first base station is facing a second sector of a second cell served by a second base station. A controller receives performance data for each of the facing cells and dynamically assigns resource blocks to each base station. The base stations use the assigned resource blocks in the facing sectors to maximize allocation to user devices served in the facing sectors while minimizing interference. The controller may analyze the performance data over time and dynamically update the assigned resource blocks to each base station for the facing sectors at various time periods based on the analysis.
