Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks with relay nodes face sub-optimal resource allocation due to variations in relay node configurations, such as different transmit powers, leading to inconsistent quality of service for end-user devices.
Innovation Solution
A system and method where a processing node identifies and prioritizes resources for relay nodes based on their configuration, including transmit power and device capabilities, to optimize backhaul connections by dynamically adjusting resource allocation based on the number and resource requirements of attached end-user devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay nodes use different transmit powers to serve varying numbers of end-user devices, then coverage and service quality are improved, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where the donor access node continuously monitors the configuration and resource usage of relay nodes, and adjusts resource allocation in real-time based on current network conditions. This allows the system to adapt to varying transmit power levels and device attachment patterns, resolving the contradiction between maintaining service quality and improving resource allocation efficiency.
Solution Approach 2:
The system changes resource allocation parameters dynamically based on relay node configuration parameters such as transmit power. By adjusting resource allocation proportions according to the actual configuration and usage patterns of different relay nodes, the system optimizes overall resource utilization while maintaining appropriate service quality for each relay node's coverage area.
2Area of stationary object
If relay nodes are configured with different transmit powers, then coverage area and device capacity are improved, but resource usage consistency deteriorates
Solution Approach 1:
The patent applies local quality by allocating resources differently to different relay nodes based on their specific configurations. Each relay node receives resource allocation proportional to its transmit power and the number of devices it serves, rather than applying a uniform resource allocation policy. This allows high-powered relay nodes to receive more resources while low-powered nodes receive fewer resources, maintaining consistency in resource usage relative to each node's capabilities.
Solution Approach 2:
The system dynamically adjusts resource allocation parameters based on relay node configuration parameters. When relay nodes are configured with different transmit powers, the donor access node modifies the resource allocation proportions accordingly, changing the resource distribution parameters to match the varying coverage areas and device capacities of different relay nodes.
3Ease of operation
If uniform resource allocation is applied to all relay nodes, then resource allocation simplicity is maintained, but quality of service for individual relay nodes deteriorates
Solution Approach 1:
The patent transitions from static uniform resource allocation to dynamic adaptive resource allocation. The donor access node continuously monitors relay node configurations and adjusts resource allocation accordingly. This dynamic approach maintains ease of operation through automated monitoring and adjustment, while simultaneously improving quality of service by ensuring each relay node receives appropriate resources based on its specific needs and configuration.
