Relay Node Configuration for Node Disjoint Paths in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently establishing node disjoint paths for reliable data transmission in wireless communication networks, particularly in scenarios requiring ultra-reliable low-latency communication, where simultaneous transmission and reception constraints limit the use of shared radio resources for backhauling and access links.
Innovation Solution
The implementation of a relay node configuration method that determines and configures additional paths using a mobile termination to establish node disjoint paths for signalling radio bearers, data radio bearers, and ultra-reliable low-latency communication data, enabling efficient data transmission by creating loop-back radio bearers and utilizing multi-connected UE configurations to minimize resource costs.

If shared radio resources are used for backhauling and access links, then resource utilization is improved, but transmission reliability deteriorates due to simultaneous transmission and reception constraints
Solution Approach 1:
The patent segments the network paths into multiple independent routes (first path and second path) between relay nodes and donor nodes. By dividing the backhauling traffic into separate paths, the system avoids simultaneous transmission and reception conflicts on shared resources, thereby maintaining both resource utilization and transmission reliability.
Solution Approach 2:
The mobile termination acts as an intermediary element that enables the establishment of node-disjoint paths. It facilitates the creation of alternative routing routes through loopback radio bearers, allowing traffic to be redirected through different physical paths without requiring additional spectrum resources.
2Reliability
If node disjoint paths are established for ultra-reliable low-latency communication, then transmission reliability is improved, but network complexity increases
Solution Approach 1:
The mobile termination performs multiple functions: it serves as both a regular user equipment and as a path establishment intermediary for creating node-disjoint routes. The loopback radio bearer mechanism is universally applicable to different types of traffic (signaling, data, ultra-reliable low-latency communication), reducing the need for separate dedicated mechanisms for each function.
Solution Approach 2:
The system uses existing network elements (mobile terminations, loopback bearers) to automatically establish node-disjoint paths without requiring complex external control mechanisms. The path establishment leverages self-organizing properties of the network, where configured bearers automatically create the necessary routing paths when activated.
3Reliability
If additional paths are configured for redundant transmission, then reliability is improved, but resource consumption increases
Solution Approach 1:
The system dynamically configures loopback radio bearers only when and where node-disjoint paths are needed for specific traffic flows. The additional paths are not permanently established but activated on-demand, allowing the network to maintain reliability for critical communications while avoiding unnecessary resource consumption during normal operation.
