Group-Based Beam Reporting for Multi-TRP Simultaneous Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam management procedures in wireless communication systems face ambiguities in associating Transmission Configuration Indicators (TCIs) with Transmission Reception Points (TRPs) and in determining whether user equipment (UE) can receive multiple beams simultaneously, leading to limitations in scheduling and resource utilization.
Innovation Solution
The proposed solution enhances group-based beam reporting by introducing new signaling procedures and configurations that allow user equipment (UE) to report the best pair of beams from different groups or TRPs, and enables network nodes to determine suitable beam pairs for simultaneous reception, thereby clarifying TCI associations and improving multi-TRP transmission capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If group-based beam reporting is used for multi-TRP operation, then resource utilization and transmission efficiency are improved, but ambiguities in TCI associations and UE simultaneous reception capabilities create scheduling limitations
Solution Approach 1:
The patent segments beam reporting by introducing separate report configurations for different TRPs, with each TRP having its own TCI state associations. This segmentation resolves the ambiguity in TCI associations by clearly defining which TCI states belong to which TRP, while maintaining the productivity benefits of group-based reporting.
Solution Approach 2:
The patent introduces an intermediary mechanism through enhanced reporting configurations that explicitly indicate UE simultaneous reception capabilities. This intermediary layer between the beam reporting and scheduling functions resolves the contradiction by providing clear information about UE capabilities, enabling better scheduling decisions without sacrificing transmission efficiency.
2Reliability
If beam reporting configurations are enhanced to clarify TCI associations, then reliability of multi-TRP operation is improved, but system complexity increases
Solution Approach 1:
The patent divides the beam reporting configuration into separate, TRP-specific segments. Each TRP has its own configuration parameters and TCI state associations, which reduces the overall complexity by organizing information in a structured, modular way rather than having a single complex configuration for all TRPs.
Solution Approach 2:
The patent applies partial action by introducing enhanced configuration elements only where needed for multi-TRP operations, rather than redesigning the entire beam reporting system. This selective enhancement improves reliability for multi-TRP scenarios while minimizing the increase in overall system complexity.
