Master Resource Allocation Module for Wireless Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks, especially frequency re-use 1 networks, face limitations in coverage and throughput due to intra-cell and inter-cell interference, which affect the efficiency of resource allocation and signal quality.
Innovation Solution
A method for coordinating resource allocation across different base stations and sectors by determining a master resource allocation module that allocates wireless resources based on link quality and traffic requirements, using RF combining for downlink signals and signal processing for uplink signals, to reduce interference and improve signal quality.

Engineering Contradiction Analysis
1Productivity
If frequency re-use 1 network is used to maximize resource utilization, then throughput is improved, but inter-cell interference increases and coverage is limited
Solution Approach 1:
The network is segmented into frequency re-use 1 cells where each cell can utilize the full frequency spectrum. Within each cell, resource allocation is further segmented by identifying border regions and inner regions, applying different power planning strategies to each segment to manage interference while maintaining throughput
Solution Approach 2:
Different resource allocation strategies are applied to different spatial locations within the network. Border region terminals receive different power planning treatment compared to inner region terminals. This local differentiation allows the system to maintain high throughput in inner regions while managing interference at cell borders
2Object-affected harmful factors
If power planning is applied to border region terminals, then inter-cell interference is reduced, but system complexity increases
Solution Approach 1:
The system dynamically identifies border regions and adjusts power planning parameters based on terminal location and channel conditions. The resource allocation module adaptively modifies transmission parameters for border region terminals, allowing the system to respond to changing interference conditions without requiring complex static configurations
Solution Approach 2:
A resource allocation module acts as an intermediary between the base station and terminals, managing the complexity of power planning and interference coordination. This intermediary handles the identification of border regions, calculation of appropriate power levels, and coordination with neighboring cells, shielding the rest of the system from complexity
