Beacon-Assisted Multi-Tier Spectrum Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-tier wireless communications systems face inefficiencies in spectrum sharing due to reliance on centralized databases, which limits network efficiency and fails to incentivize tier-2 entities to participate, and does not allow unused spectrum to be shared by tier-3 entities, leading to insufficient bandwidth for advanced technologies like 5G NR.
Innovation Solution
Implementing a beacon-assisted spectrum sharing method where higher-tier entities transmit periodic beacon signals containing spectrum usage information, allowing lower-tier entities to autonomously coordinate and synchronize, thereby enabling efficient inter-tier and intra-tier spectrum sharing without the need for centralized databases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized databases are used for spectrum sharing, then coordination between tiers is achieved, but network efficiency is limited and tier-2 entities are not incentivized to participate
Solution Approach 1:
The patent extracts the centralized database function from the spectrum sharing system and replaces it with distributed beacon signal transmissions from individual network entities. Each entity independently broadcasts its spectrum usage information through beacons, eliminating the need for centralized coordination while maintaining reliable inter-tier spectrum sharing.
Solution Approach 2:
The patent enables network entities to autonomously obtain spectrum sharing information by receiving and processing beacon signals from other entities. Tier-2 and tier-3 entities can independently determine available spectrum resources without requiring centralized database queries, thereby improving network efficiency and incentivizing participation through autonomous operation.
2Reliability
If centralized databases are used for spectrum sharing, then resource allocation is managed, but unused spectrum cannot be shared by tier-3 entities
Solution Approach 1:
The patent segments the centralized resource allocation function into distributed beacon signal exchanges between individual network entities. Each entity broadcasts its own spectrum usage status through beacons, allowing tier-3 entities to independently identify and utilize unused spectrum resources without centralized control, thereby enhancing sharing flexibility and adaptability.
Solution Approach 2:
The patent implements dynamic spectrum sharing where beacon signals continuously update spectrum availability information in real-time. Tier-3 entities can dynamically access unused spectrum by monitoring beacon transmissions, enabling flexible and adaptive resource utilization that responds to changing network conditions without rigid centralized allocation.
3Productivity
If more spectrum bandwidth is allocated to support 5G NR, then capacity increases, but spectrum is a limited and regulated resource
Solution Approach 1:
The patent adds a new dimension to spectrum utilization by implementing multi-tier spectrum sharing with beacon-assisted coordination. This enables vertical layering of network tiers (tier-2, tier-3) that can simultaneously access different portions of the spectrum, effectively increasing capacity without requiring additional spectrum bandwidth by utilizing the hierarchical dimension.
Solution Approach 2:
The patent changes the operational parameters of spectrum sharing by introducing beacon signal-based coordination mechanisms. Through adjustable beacon transmission intervals, power levels, and information content, the system optimizes spectrum utilization efficiency to maximize capacity from limited available spectrum resources while supporting 5G NR requirements.
