5G IAB Node Resource Coordination for QoS Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G IAB networks, existing signaling interaction processes fail to effectively manage user radio bearers and backhaul link channels, leading to potential service rejection due to incomplete coordination among multiple nodes, and hinder efficient control information transmission between nodes, affecting data scheduling strategies.
Innovation Solution
A resource management method and apparatus that enable nodes in a 5G IAB network to transmit and receive resource management requests and responses, and transmit control information, allowing for coordinated management of user radio bearers and backhaul link channels across multiple nodes, ensuring that nodes can adjust resources to meet QoS requirements and avoid service rejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing signaling interaction processes are used in 5G IAB networks, then network deployment is simplified, but resource coordination among multiple nodes becomes incomplete leading to service rejection
Solution Approach 1:
The patent segments the resource management process into distinct phases: initial resource allocation, ongoing resource coordination, and fallback mechanisms. Each phase handles specific coordination tasks independently, preventing complete process failure and ensuring service continuity even when certain signaling interactions are incomplete.
Solution Approach 2:
The patent implements preliminary resource reservation and pre-coordination procedures before actual service delivery. Nodes exchange resource capability information in advance and establish resource pools beforehand, so that when service requests arrive, coordinated resources are already available, preventing service rejection due to lack of coordination.
2Productivity
If traditional control information transmission is used between nodes, then transmission protocol is simple, but data scheduling efficiency is hindered
Solution Approach 1:
The patent designs control information structures that serve multiple functions simultaneously: resource allocation, scheduling directives, quality of service parameters, and coordination status indicators are all embedded in unified control messages. This multi-functional approach improves scheduling efficiency while ensuring complete information transmission without requiring separate protocols for each function.
Solution Approach 2:
The patent implements feedback mechanisms where receiving nodes acknowledge control information and report scheduling outcomes. This feedback loop ensures that control information is successfully transmitted and interpreted, allowing transmitting nodes to adjust subsequent control messages, thereby maintaining information completeness while optimizing scheduling efficiency.
3Reliability
If nodes operate independently without coordination, then node operation is simple, but QoS requirements cannot be met
Solution Approach 1:
The patent enables nodes to autonomously select and execute appropriate coordination mechanisms based on service requirements and current network state. Nodes self-manage their resource allocations within pre-coordinated pools and automatically adjust operations to meet QoS targets without complex centralized control, maintaining operational simplicity while ensuring QoS guarantees through structured coordination frameworks.
