Dynamic Channel Priority for CBRS Spectrum Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in ultra-dense networks, there is a shortage of spectrum resources due to the increasing demand for high-speed communications, leading to inefficiencies in spectrum utilization, particularly among General Authorized Access (GAA) users in the Citizens Broadband Radio Service (CBRS) framework, where there are no definite rules for spectrum sharing, resulting in conflicts and reduced spectral efficiency.
Innovation Solution
An electronic apparatus and method that acquire and select extended channels based on channel priority level parameters, manage conflicts through dynamic assignment, and determine primary channel reassignment factors to optimize spectrum utilization, using techniques like the Multi-Armed Bandit algorithm to select and reassign channels efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spectrum extension is allowed for CBSDs to improve spectral efficiency, then spectral efficiency is improved, but channel contention and conflicts increase among GAA users
Solution Approach 1:
The patent introduces channel priority level parameters that can be dynamically adjusted based on load conditions. The spectrum management device changes the priority parameters of channels to control which CBSDs can extend into them, thereby managing spectral efficiency while reducing conflicts through parameter-based control
Solution Approach 2:
The patent implements a feedback mechanism where the spectrum management device monitors load conditions of CBSDs and adjusts channel priority parameters accordingly. When load exceeds thresholds, the system feedbacks priority changes to resolve contention and maintain spectral efficiency
2Adaptability or versatility
If dynamic spectrum extension is performed to support frequent load changes in ultra-dense networks, then adaptability to load changes is improved, but system complexity increases
Solution Approach 1:
The patent makes the channel priority parameters dynamic rather than static. The spectrum management device continuously adjusts priority levels based on real-time load conditions, enabling the system to adapt to frequent changes in ultra-dense networks while maintaining manageable complexity through automated control
Solution Approach 2:
The system enables CBSDs to autonomously monitor their own load conditions and trigger spectrum extension requests when thresholds are exceeded. This self-service approach reduces the burden on the spectrum management device and simplifies overall system complexity
3Productivity
If multiple CBSDs are allowed to use the same extended channel, then spectrum utilization is improved, but interference and conflicts between CBSDs increase
Solution Approach 1:
The patent assigns different channel priority levels to different channels based on local conditions and CBSD requirements. Each channel has customized priority parameters that reflect its specific usage patterns and interference characteristics, allowing multiple CBSDs to coexist with minimized interference through localized quality differentiation
