Spectrum Management Device for Interference-Free Secondary System Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Limited spectrum resources for secondary systems in wireless communication systems lead to inefficient use due to interference, necessitating a method to reasonably allocate resources without interfering with primary systems.
Innovation Solution
A spectrum management device and system that determine an interference relation diagram among coexistence groups, allocating shared or distinct spectrum resources based on the diagram to prevent interference between secondary systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spectrum resources are allocated to multiple secondary systems, then spectrum utilization is improved, but interference between secondary systems increases
Solution Approach 1:
The patent segments the set of secondary systems into multiple coexistence groups based on interference relationships. Systems within the same group are guaranteed not to interfere with each other, allowing simultaneous spectrum allocation to multiple groups while preventing intra-group interference. This segmentation enables higher overall spectrum utilization without compromising system reliability.
2Productivity
If spectrum resources are allocated to secondary systems dynamically, then resource efficiency is improved, but complexity of spectrum management increases
Solution Approach 1:
The patent introduces a spectrum management device as an intermediary between primary and secondary systems. This device automatically determines interference relationships, constructs interference relation diagrams, and allocates spectrum resources dynamically. By offloading the complex management tasks to this intermediary, the system achieves high resource efficiency while the complexity is centralized and automated rather than distributed across all systems.
3Adaptability or versatility
If more secondary systems are allowed to use the same spectrum, then spectrum resource availability is improved, but reliability of interference-free operation deteriorates
Solution Approach 1:
The patent performs preliminary determination of interference relationships and pre-constructs interference relation diagrams before spectrum allocation. By identifying and resolving potential interference issues in advance through the coexistence group formulation, the system can confidently allocate spectrum to more secondary systems while guaranteeing interference-free operation. The reliability is ensured because the interference relationships are established beforehand rather than reacting to interference as it occurs.

AI summary
The present disclosure relates to a spectrum management device, system and method, and a computer-readable storage medium. The spectrum management device according to the present disclosure includes a processing circuit, configured to: determining a first interference relationship diagram between coexisting groups consisting of one or more sub-systems, wherein the points in the first interference relationship diagram represent the coexisting groups, the line between two points represents that interference exists between two coexisting groups represented by the two points; and allocating a spectrum resource for each of the multiple coexisting groups according to the first interference relationship diagram, so that two coexisting groups represented by two points not connected by a line use a same spectrum resource, and two coexisting groups represented by two points connected by a side use different spectrum resources.
