Boundary IAB Node Selection for Load-Aware Network Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As 5G becomes widespread, not all IAB nodes are capable of functioning as boundary IAB nodes due to equipment specification and resource limitations, leading to increased system load and potential wireless link failures.
Innovation Solution
A communication apparatus and method that determines whether an IAB node can operate as a boundary IAB node, transmitting a message indicating its capability, allowing the IAB donor to selectively implement necessary processes, thereby reducing system load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all IAB nodes are configured to function as boundary IAB nodes, then network coverage and redundancy are improved, but system load increases and equipment resource requirements worsen
Solution Approach 1:
The patent applies local quality by enabling only specific IAB nodes with sufficient resources to function as boundary IAB nodes, rather than requiring all nodes to have this capability. The determination unit evaluates individual node capabilities (processing power, memory, energy) and selectively activates boundary functionality where appropriate, optimizing the balance between network coverage and system load.
2Reliability
If boundary IAB node functionality is implemented, then communication redundancy is improved, but equipment specification requirements worsen
Solution Approach 1:
The patent uses parameter changes by dynamically adjusting the operational parameters of IAB nodes based on their capability assessments. The determination unit changes the functional state of nodes (from standard to boundary functionality) based on evaluated parameters such as processing capability, memory availability, and energy status, allowing the system to adapt to varying equipment specifications without requiring all nodes to meet high threshold requirements.
3Reliability
If boundary IAB node operations are enforced, then network stability is improved, but resource consumption increases
Solution Approach 1:
The patent applies partial action by implementing boundary IAB node functionality only in nodes where it is truly necessary and beneficial. The determination unit assesses whether each node should operate as a boundary node based on current network conditions and node capabilities, activating this enhanced functionality only where needed rather than universally, thus reducing overall resource consumption while maintaining network stability.

AI summary
Disclosed is a communication apparatus characterized by including a determination unit configured to determine whether or not its own node functioning as an IAB (Integrated Access and Backhaul) node which forms one IAB network is capable of operating as a boundary IAB node which serves as an IAB node connecting to both the one IAB network and another IAB network, and a transmission unit configured to transmit, based on a determination result of the determination unit, a communication message according to the determination result.
