Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in managing resource assignments for relay wireless devices to mitigate congestion and ensure high-quality service to both relay and normal wireless devices, especially in areas with high traffic loads.
Innovation Solution
Distributing relay wireless devices across available frequency bands at an access node by assigning specific traffic class identifiers and frequency bands, reserving resources to prevent congestion and optimize communication, and utilizing relay wireless devices with enhanced computational and RF capabilities to relay data between access nodes and small cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay wireless devices are deployed at the edge of coverage areas to improve coverage and throughput, then service quality and coverage are improved, but congestion and resource conflicts with normal wireless devices occur
Solution Approach 1:
The patent segments frequency bands into relay-specific frequency bands and normal device frequency bands. Relay wireless devices are assigned to specific frequency bands (e.g., frequency band 2) while normal wireless devices use other frequency bands (e.g., frequency band 1), thereby separating their communication channels and eliminating congestion and resource conflicts at the access node.
2Productivity
If multiple wireless devices are assigned to the same frequency band to increase throughput, then available throughput increases, but resource conflicts and congestion increase
Solution Approach 1:
The patent creates a separate resource allocation system for relay wireless devices by copying the frequency band structure. Instead of managing all devices in a single shared frequency band, the system creates dedicated frequency band assignments for relay devices, simplifying resource management while maintaining high throughput for both relay and normal devices.
3Area of stationary object
If relay wireless devices are used to relay data between access nodes and small cells, then coverage extension and service quality are improved, but the impact on normal wireless devices serviced by the access node increases
Solution Approach 1:
The patent segments the communication resources by assigning relay wireless devices to specific frequency bands that are separate from those used by normal wireless devices. This segmentation ensures that relay operations extending coverage area do not generate harmful interference or congestion for normal devices, as they operate on dedicated spectral resources.

AI summary
Exemplary embodiments described herein include systems, methods, and nodes for distributing relay wireless devices across an access node. Network identification numbers associated with at least two wireless devices may be determined. At an access node, a traffic class identifier and frequency band may be assigned to the at least two wireless devices, wherein each frequency band available for communication at the access node is assigned at most a maximum number of wireless devices comprising a network identification number that meets the criteria. Data may then be communicated between the access node and the at least two wireless devices according to the assigned traffic class identifiers and frequency bands, wherein the wireless devices comprise relay wireless devices that relay data between the access node and one or more small cells.
