CBRS Jamming Mitigation Through WiFi-Mediated UE Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unregistered Citizens Broadband Radio Service Devices (CBSDs) can unintentionally or intentionally jam the Citizens Broadband Radio Service (CBRS) band, causing interference, which the Spectrum Access System (SAS) cannot detect or control due to lack of registration.
Innovation Solution
Incorporate mobile network user equipment (UE) information into WiFi network communications to identify potential jamming conditions, enabling a WiFi control entity to communicate UE identification to provider equipment for mitigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the SAS monitors all devices in the CBRS band, then jamming detection capability improves, but system complexity and resource consumption increase significantly
Solution Approach 1:
The patent introduces WiFi as an intermediary monitoring system. Instead of the SAS directly monitoring all CBRS devices, WiFi devices act as intermediaries that detect jamming signals in the CBRS band and report to the SAS. This reduces the complexity and resource consumption of the SAS while maintaining jamming detection capability across the entire band.
Solution Approach 2:
The patent enables unregistered devices to self-report their presence and status to the SAS through WiFi communications. By inserting UE information into WiFi network communications, devices automatically provide identification and location data, allowing the SAS to identify potential jammers without active monitoring of each device.
2Reliability
If the SAS controls all CBSD operations, then interference management improves, but the ability to control unregistered devices deteriorates
Solution Approach 1:
The patent uses WiFi communication as an intermediary channel to extend SAS control capability to unregistered devices. By leveraging existing WiFi infrastructure and communications, the SAS can send control signals and receive status information from devices that are not traditionally registered in the CBRS system, thereby expanding interference management coverage.
Solution Approach 2:
The patent makes the WiFi infrastructure serve multiple functions: it acts as both a communication medium for data transmission and a control channel for SAS management commands. This multi-functionality allows the system to control unregistered devices using existing infrastructure without requiring dedicated control channels for each device type.
3Measurement precision
If the system waits for complaints to identify jammers, then false positives reduce, but response time to active jamming increases
Solution Approach 1:
The patent implements preliminary monitoring and detection mechanisms that continuously scan for jamming signals before complaints arise. By proactively detecting interference patterns and identifying potential jammers in advance, the system can take mitigating actions before service degradation occurs, reducing both false positives and response time.
Solution Approach 2:
The patent establishes a feedback loop where the SAS receives continuous status reports from WiFi devices and CBSDs about signal quality and interference levels. This real-time feedback enables the system to dynamically adjust operations and identify jammers based on actual measured conditions rather than waiting for service complaints, improving both accuracy and response time.

Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for managing service provider network nodes in a converged network by inserting mobile network UE information into WiFi network communications such that a WiFi control entity may, in response to determining that the UE-inserted information is indicative of a jamming condition at a Citizens Broadband Radio Service Devices (CBSDs) providing mobile network services to the UE, communicate the identification of such UE to various provider equipment such that CBSDs experiencing jamming signals may be identified and mitigation steps taken.
