IAB Soft Resource Indication in Multi-TRP Conflict Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for IAB-MT in multi-DCI based multi-TRP operation fail to effectively handle conflicts in soft resource availability indications due to independent DCI from multiple TRPs, leading to collisions and inefficient resource utilization.
Innovation Solution
Implementing a method for IAB-MT that applies soft resource availability indications based on novel approaches, including dynamic coordination and predefined time offsets to resolve conflicts and ensure consistent resource availability across TRPs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent DCI from multiple TRPs are used for resource allocation, then resource allocation flexibility is improved, but resource collision and conflict increase
Solution Approach 1:
The patent introduces a coordinator entity that acts as an intermediary between multiple TRPs and the IAB-MT. This coordinator receives resource allocation requests from multiple TRPs, resolves conflicts between them, and coordinates resource assignments to prevent collisions at the IAB-MT, thereby maintaining both flexibility and reliability
Solution Approach 2:
The patent implements feedback mechanisms where the IAB-MT reports resource availability and collision status back to the network. This feedback loop enables dynamic adjustment of resource allocations from multiple TRPs, allowing the system to adapt and resolve conflicts based on real-time conditions while maintaining allocation flexibility
2Productivity
If soft resource availability indication is applied without coordination, then resource utilization efficiency is improved, but conflict resolution complexity increases
Solution Approach 1:
The patent applies soft resource availability indications in advance before actual resource allocation conflicts occur. By pre-coordinating resource availability status from multiple TRPs and resolving potential conflicts beforehand, the system improves resource utilization efficiency while avoiding the need for complex real-time conflict resolution mechanisms
Solution Approach 2:
The patent changes the parameter of resource availability from a static binary state to a dynamic soft indication that can be adjusted based on coordination outcomes. This parameter change allows for more nuanced resource management, improving utilization efficiency while keeping conflict resolution complexity manageable through standardized adjustment rules
