Solution Overview
Problem
Radio communication networks face interference issues due to increasing signal transmission, which deteriorate transmission efficiency and capacity, especially with multiple base stations and terminals, where existing methods fail to effectively manage interference across all allocated radio resources.
Innovation Solution
A network apparatus and method that selectively or simultaneously apply interference control schemes, such as interference alignment, neutralization, or cancellation, and transmission power control schemes, based on signal quality information, to manage interference and optimize radio resource allocation, using techniques like dynamic spectrum management to enhance signal reception efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the amount of signals transmitted in the radio communication network is increased to meet growing demand, then the network capacity and service coverage are improved, but interference signals between base stations and terminals deteriorate transmission efficiency
Solution Approach 1:
The patent implements dynamic selection between interference control schemes (interference alignment, neutralization, cancellation) and transmission power control schemes based on real-time signal quality information. This dynamic adaptation allows the system to optimize network capacity while managing interference signals effectively in varying network conditions
Solution Approach 2:
The system changes transmission parameters (interference control method selection, transmission power levels) based on signal quality information to resolve the contradiction between increasing network capacity and managing interference signals. By adjusting these parameters dynamically, the system achieves both goals simultaneously
2Productivity
If interference control schemes are applied to manage interference signals, then transmission efficiency is improved, but device complexity and computational requirements increase
Solution Approach 1:
The patent applies interference control schemes selectively rather than universally - choosing to apply interference alignment, neutralization, or cancellation only when signal quality information indicates it is beneficial. This partial application reduces computational complexity while maintaining transmission efficiency where needed
Solution Approach 2:
The system segments the network into different operational modes by selecting appropriate interference control schemes for specific base station-terminal pairs based on their individual signal quality conditions. This segmentation allows complex interference control to be applied only where necessary, reducing overall system complexity
3Productivity
If transmission power control scheme is applied to reduce interference impact, then signal reception efficiency is improved, but energy consumption increases
Solution Approach 1:
The system dynamically changes transmission power levels based on signal quality information and selected interference control schemes. By adjusting power parameters only when and where necessary, the system improves signal reception efficiency while minimizing overall energy consumption in the network
