Relay Node Indication Signaling for Parent-Link Resource Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face resource conflicts when a relay node switches to a new parent node, leading to the need for reconfiguration of subordinate links, which is inefficient and disruptive.
Innovation Solution
A method involving a relay node transmitting indication information to a new parent node to coordinate transmission resources, ensuring compatibility with existing multiplexing modes and resources, and receiving feedback to determine a new configuration that avoids conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a relay node accesses a new parent node using existing methods, then the relay node can establish a new link, but resource conflicts occur between the new link and subordinate links, requiring reconfiguration or causing service interruption
Solution Approach 1:
The relay node performs preliminary actions by determining transmission resources for the new link before actually establishing it. The relay node identifies available resources that do not conflict with existing subordinate links, and prepares resource configuration information in advance. This preliminary resource determination prevents future conflicts and avoids service interruption when the new link is established.
Solution Approach 2:
The system implements feedback mechanisms where the relay node reports resource configuration information to the network controller. The network controller provides feedback regarding resource allocation decisions, and the relay node adjusts its resource selection based on this feedback. This closed-loop feedback ensures that resource conflicts are detected and resolved, maintaining reliability of subordinate links while enabling parent node switching.
2Reliability
If transmission resources are reconfigured to avoid conflicts, then resource conflicts are eliminated, but system complexity and reconfiguration overhead increase
Solution Approach 1:
The relay node performs self-service by autonomously determining transmission resources for the new link without requiring extensive network controller intervention. The relay node independently identifies available resources, evaluates potential conflicts with subordinate links, and selects appropriate resource configurations. This self-service approach reduces system complexity while ensuring reliable conflict avoidance.
3Reliability
If subordinate child nodes access a new parent node, then resource conflicts are avoided, but service continuity is disrupted and handover overhead increases
Solution Approach 1:
The system segments the resource management function, allowing the relay node to independently manage transmission resources for its own links while maintaining separate management for subordinate links. This segmentation enables the relay node to switch parent nodes without forcing subordinate nodes to perform handovers, thereby avoiding service disruption and reducing handover overhead while still preventing resource conflicts.
