RF Resource Allocation System Dynamic Spectrum Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high demand for RF spectrum resources, particularly for wireless broadband, leads to inefficient allocation and high costs due to semi-permanent government allocation, making it difficult to reclaim or reuse frequency ranges, even when sections are underutilized, necessitating an improved method for dynamic and efficient access.
Innovation Solution
A device with a transceiver and processor that communicates with a RF resource allocation system to determine permission to use the RF resource, employing cumulative usage checks and threshold comparisons to minimize impact on other users and comply with regulations, specifically for unlicensed CBRS spectrum through the FCC SAS system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If government officials allocate RF spectrum on a semi-permanent basis to licensees, then RF spectrum access is controlled and authorized, but it becomes difficult to reclaim and reuse frequency ranges even when sections are underutilized, leading to inefficient allocation
Solution Approach 1:
The patent implements dynamic RF spectrum allocation where the system transitions from static, semi-permanent government allocation to real-time, automated allocation. The RF resource allocation system dynamically assigns and reassigns spectrum based on current utilization needs, allowing frequency ranges to be reclaimed and reallocated efficiently when underutilized, thus resolving the contradiction between reliable access control and allocation efficiency
Solution Approach 2:
The system employs feedback mechanisms where the RF resource allocation system continuously monitors spectrum utilization and automatically adjusts allocations. This feedback loop enables the system to detect underutilized frequency ranges and reallocate them promptly, maintaining reliable access control while significantly improving overall spectrum allocation efficiency and preventing waste
2Productivity
If automated systems allocate RF spectrum rapidly and dynamically to individual devices, then allocation efficiency increases and costs decrease, but the systems do not specify or restrict what the RF spectrum must be used for, relying on competition to drive efficiency
Solution Approach 1:
The patent applies local quality by implementing specific usage requirements and restrictions for different RF spectrum allocations. Rather than uniform, unrestricted allocation, the system tailors spectrum usage conditions to local needs and purposes, specifying what the RF spectrum must be used for in different contexts while maintaining rapid automated allocation processes
Solution Approach 2:
The system changes allocation parameters dynamically, adjusting both the speed of allocation and the usage restrictions based on specific conditions. This allows the automated system to maintain high allocation speed while adapting versatility and usage control to match specific application requirements, resolving the contradiction between rapid allocation and usage adaptability
3Reliability
If a device repeatedly communicates with the RF resource allocation system to obtain permission, then the device ensures regulatory compliance and minimizes impact on other users, but the cumulative use of the RF resource increases
Solution Approach 1:
The patent implements preliminary action by having devices obtain permission in advance through the RF resource allocation system before actual data transmission. This preliminary authorization process ensures regulatory compliance and minimizes impact on other users, while the system optimizes the frequency and timing of these permission checks to reduce unnecessary cumulative RF resource consumption during the authorization process

AI summary
A device obtains permission to use a Radio Frequency (RF) resource to transmit/receive data. The device comprises a transceiver and a processor that: controls the transceiver to communicate with a RF resource allocation system over the RF resource to determine whether the device can use the RF resource; while the transceiver communicates with the RF resource allocation system, repeatedly determines whether a cumulative use of the RF resource satisfies a condition until the processor determines that the cumulative use satisfies the condition or the device is permitted to use the RF resource; upon the processor determining that the cumulative use satisfies the condition, control the transceiver to not communicate with the RF resource allocation system over the RF resource for a period of time; and upon determining that the device is permitted to use the RF resource, controls the device to use the RF resource to transmit/receive the data.
