Non-Coordinated Spectrum Channel Reassignment via Interference Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-coordinated shared spectrum systems, devices often experience interference due to uncoordinated channel assignments, leading to inefficiencies and increased operational costs, as existing interference-minimizing protocols may not be available or practical for all devices.
Innovation Solution
A method and system that utilize data from notifications of interference to determine the coverage area of an antenna and generate a map indicating available channels, allowing for intelligent channel reassignment to minimize interference, thereby reducing the risk of channel conflicts and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If devices are assigned channels without coordination in a shared spectrum system, then device autonomy and ease of operation are improved, but interference between devices increases and communication reliability deteriorates
Solution Approach 1:
Each device independently monitors its assigned channel for interference conditions and autonomously determines when to initiate a channel reassignment request, eliminating the need for centralized coordination while maintaining reliable communication through self-directed interference management
Solution Approach 2:
The system implements a feedback mechanism where devices continuously monitor channel quality and provide interference information back to the channel assignment system, enabling dynamic channel reassignment decisions that maintain communication reliability without requiring centralized control
2Reliability
If interference-minimizing protocols are implemented on all devices, then communication reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent introduces an intermediary channel assignment system that acts as a mediator between devices and the spectrum environment. This intermediary handles the complex interference monitoring and channel reassignment logic centrally, allowing individual devices to remain simple while still achieving reliable communication through the intermediary's coordination
3Reliability
If centralized coordination of channel assignments is implemented, then interference is reduced and communication reliability is improved, but system complexity and operational cost increase
Solution Approach 1:
The patent segments the channel assignment function into distributed components, where each device independently monitors its own channel conditions and autonomously requests reassignments when needed. This segmentation eliminates the need for a centralized coordination system while maintaining communication reliability through distributed interference management
Data Source
AI summary
Aspects of the disclosure relate to a non-coordinated shared spectrum system. One or more processors are configured receive data associated with a notification from a device experiencing interference on an assigned channel. The one or more processors may determine a coverage area of an antenna providing the assigned channel to the device and determine based on the data associated with the notification, available channels within the coverage area of the antenna. The one or more processors may generate a map based on the data associated with the notification, wherein the map indicates the available channels within the coverage area of the antenna.
