IAB Node Resource Pattern Configuration for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing resource configurations for integrated access and backhaul (IAB) nodes, leading to uncertainty about the availability of resources for communication, which hampers network resource utilization.
Innovation Solution
The method involves an IAB node receiving a resource pattern from a child IAB node, which indicates the configuration of resources such as whether they are hard, soft, or unavailable. This information allows the parent node to determine if a communication can be freely scheduled and whether a release indicator is necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource configurations for IAB nodes are managed without clear patterns, then scheduling flexibility is maintained, but resource availability certainty deteriorates
Solution Approach 1:
The patent segments resource configurations into distinct types (hard resources, soft resources, and unavailable resources) with specific characteristics. This segmentation provides clear patterns for resource availability while maintaining manageable complexity through standardized classification.
Solution Approach 2:
The patent changes the parameter of resource configuration clarity by introducing explicit pattern indicators that define resource availability characteristics. This parameter change transforms uncertain resource management into a structured approach with defined states.
2Productivity
If detailed resource patterns are provided for all IAB nodes, then resource utilization efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential resource pattern information needed for scheduling decisions, rather than transmitting complete configuration details. This extraction approach improves resource utilization efficiency while minimizing signaling overhead by sharing only critical pattern indicators.
Solution Approach 2:
The patent creates a universal resource pattern indicator that serves multiple functions: it indicates resource availability, defines scheduling constraints, and provides configuration status. This multi-functionality reduces the need for separate signaling messages for each purpose.
3Adaptability or versatility
If resource patterns are dynamically updated, then adaptability to network conditions is improved, but scheduling uncertainty increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring resource patterns with defined characteristics before scheduling occurs. This allows the network to adapt to changing conditions while maintaining scheduling certainty, as the pattern definitions are established in advance and provide clear guidance for resource allocation decisions.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive at least part of a resource pattern of a child IAB node associated with the IAB node. The resource pattern may indicate one or more configurations of one or more resources of the child IAB node. The IAB node may communicate with the child IAB node based on the at least part of the resource pattern. Numerous other aspects are provided.
