Dynamic Spectrum Allocation for Interference Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks lack flexible spectrum allocation and cooperation among different access technologies, leading to inefficient spectrum usage due to fixed spectrum loads and lack of dynamic spectrum reallocation, which results in reduced spectrum efficiency and interference issues during system reconfiguration.
Innovation Solution
A method and apparatus for allocating spectrums during system reconfiguration by calculating reconfigurable spectrums, including dedicated, reusable, and loanable spectrums, and allocating them to cells in overlap and non-overlap regions to ensure effective interference suppression and quality of service satisfaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed spectrum allocation is used in existing wireless access technologies, then system simplicity is maintained, but spectrum efficiency is reduced due to inability to dynamically allocate spectrums among different access technologies
Solution Approach 1:
The patent implements dynamic spectrum allocation by enabling base stations of different wireless access technologies to dynamically adjust and share spectrum resources based on real-time network conditions and service requirements, transforming the fixed spectrum allocation into a flexible and adaptive system
Solution Approach 2:
The patent creates a universal spectrum management mechanism that can be applied across multiple wireless access technologies (such as LTE and NR), allowing different technologies to share common spectrum resources and management protocols, thereby improving spectrum efficiency without significantly increasing individual system complexity
2Adaptability or versatility
If spectrum reallocation during system reconfiguration is performed without interference suppression, then spectrum flexibility is improved, but interference between cells increases
Solution Approach 1:
The patent applies local quality by identifying overlap regions where cells from different wireless access technologies coexist and applying specific interference suppression spectrum allocation strategies in these localized areas, while non-overlap regions can use more flexible spectrum allocation without the same interference constraints
Solution Approach 2:
The patent converts the harmful interference effect into a beneficial mechanism by using the identified overlap regions to establish dedicated interference suppression rules, where the interference problem directly drives the creation of targeted spectrum allocation strategies that protect both overlapping and non-overlapping cells
3Object-affected harmful factors
If dedicated spectrums are allocated to all cells to suppress interference, then interference levels are reduced, but spectrum efficiency decreases due to inability to share spectrums
Solution Approach 1:
The patent segments spectrum resources into different types (dedicated spectrums for interference-prone overlap regions and shareable spectrums for non-overlapping regions), allowing the system to apply appropriate allocation strategies to each segment, thereby achieving both interference suppression and spectrum efficiency
Solution Approach 2:
The patent dynamically changes spectrum allocation parameters based on cell location and overlap status, adjusting the degree of spectrum dedication and sharing according to real-time network conditions, service requirements, and interference measurements, thus optimizing both interference suppression and spectrum utilization

AI summary
A method and an apparatus for allocating spectrums are provided in the disclosure. The method includes: reconfigurable spectrums for a target group domain are calculated, wherein said reconfigurable spectrums contain one or more of a dedicated spectrum, a reusable spectrum and a loanable spectrum; during the system reconfiguration, spectrums are allocated to cells of the target group domain in a non-overlap region after spectrums are allocated to cells of the target group domain in an overlap region according to the reconfigurable spectrums. By use of the disclosure, the spectrum allocation can be implemented during the system reconfiguration, and interference can be effectively suppressed.
