Spectrum Coordinator for Dynamic Wireless Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The growing demand for wireless spectrum due to increased mobile broadband usage has made traditional methods of spectrum allocation, such as repurposing, costly and inefficient, necessitating new approaches for coordinating spectrum use among different users.
Innovation Solution
A method of spectrum coordination where a spectrum coordinator determines protection criteria for primary users and shares them with a geo-location database to assign shared spectrum to other users, enabling a hierarchical, multi-tiered spectrum sharing model that includes procedures for registration, reconfiguration, and incentive-based spectrum allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If spectrum is allocated through traditional repurposing methods, then primary users can be moved to other bands, but the process becomes extremely costly and lengthy
Solution Approach 1:
A spectrum coordinator is introduced as an intermediary entity that manages spectrum sharing between primary and secondary users. The coordinator receives protection requirements from primary users, determines appropriate protection criteria, and communicates with geo-location databases to enable dynamic spectrum allocation without requiring physical repurposing of bands
Solution Approach 2:
The patent implements dynamic spectrum sharing where spectrum allocation is not fixed but can change based on real-time conditions. Secondary users can dynamically access spectrum resources that are not currently being used by primary users, allowing flexible adaptation to changing spectrum需求的 while maintaining primary user protection
2Quantity of substance
If spectrum is allocated through traditional repurposing methods, then primary users can be moved to other bands, but the cost becomes extremely high
Solution Approach 1:
The spectrum coordinator acts as a cost-effective intermediary that enables spectrum sharing through coordination and information exchange rather than expensive physical infrastructure changes or service migrations. This approach avoids the billions of dollars in costs associated with traditional repurposing
Solution Approach 2:
The system uses geo-location databases to store and share spectrum usage information, creating a virtual copy of spectrum allocation data that can be accessed by multiple users and coordinators. This eliminates the need for expensive physical spectrum reconfiguration while maintaining accurate tracking of primary user locations and usage patterns
3Adaptability or versatility
If spectrum sharing is implemented without coordination, then more users can access spectrum, but interference between users increases
Solution Approach 1:
The system implements feedback mechanisms where the spectrum coordinator continuously monitors spectrum usage conditions, receives protection requirements from primary users, and adjusts spectrum allocation to secondary users based on this feedback. This ensures that spectrum sharing continues while maintaining acceptable interference levels through iterative optimization
Solution Approach 2:
The spectrum coordinator and geo-location database serve as intermediaries that enable controlled spectrum sharing. They mediate between primary and secondary users by enforcing protection criteria, validating spectrum access requests, and ensuring that secondary user transmissions do not harmful interfere with primary user communications

AI summary
Methods and apparatus for spectrum coordination are described. A method of spectrum coordination includes a spectrum coordinator receiving a request for shared spectrum from a CRS that the spectrum coordinator supports. The request includes at least one minimum protection requirement. The spectrum coordinator determines protection criteria for the CRS based on the at least one minimum protection requirement received from the CRS. The spectrum coordinator sends the protection criteria for the CRS to a geo-location database for use in assigning shared spectrum to other CRSs that the spectrum coordinator does not support.
