Resource Measurement for Multi-TRP Beam Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods struggle to select beams from different transmission reception points (TRPs) for multi-station data transmission, as terminals often choose beams from the same TRP when configured to report simultaneously receivable resources.
Innovation Solution
A resource measurement method that allows terminals to send measurement results indicating resources that can be simultaneously received from different TRPs, enabling simultaneous data transmission by selecting resources from multiple TRPs based on measurement configuration information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal reports two resources that can be simultaneously received, then the terminal can receive signals from two beams, but the two beams may belong to the same TRP and cannot achieve multi-station data transmission
Solution Approach 1:
The patent divides the resource reporting into two independent parts: first resource reporting (indicating resources from different TRPs) and second resource reporting (indicating resources from the same TRP). This segmentation allows the terminal to selectively report resources from different TRPs for multi-station transmission while maintaining the ability to report resources from the same TRP when appropriate, thereby resolving the contradiction between achieving multi-station capability and ensuring accurate beam selection.
Solution Approach 2:
The patent introduces a network device as an intermediary that receives both first measurement results (from different TRPs) and second measurement results (from the same TRP). The network device then determines the final beam selection based on both reports, enabling multi-station data transmission while maintaining measurement precision through the coordinated evaluation of both resource sets.
2Productivity
If the terminal selects beams from the same TRP, then the beam selection process is simple, but multi-station data transmission cannot be implemented
Solution Approach 1:
The patent segments the resource measurement process into two distinct reporting mechanisms: first resource reporting for inter-TRP resources and second resource reporting for intra-TRP resources. This segmentation enables the terminal to maintain simple beam selection within a single TRP while also capturing opportunities for multi-station transmission from different TRPs, thereby improving data transmission efficiency without excessively increasing complexity.
Solution Approach 2:
The patent applies partial action by requiring the terminal to perform resource measurement and reporting only when necessary. The terminal reports first measurement results when resources from different TRPs are available and second measurement results when resources from the same TRP are selected. This partial reporting approach improves productivity by enabling multi-station transmission when beneficial while avoiding unnecessary complexity when single-TRP transmission suffices.
3Adaptability or versatility
If the terminal reports resources from multiple TRPs, then multi-station data transmission is enabled, but the reporting flexibility and accuracy are reduced
Solution Approach 1:
The patent segments the reporting process into two clear, distinct reporting mechanisms: first resource reporting for inter-TRP resources and second resource reporting for intra-TRP resources. This segmentation maintains reporting flexibility by allowing the terminal to use the appropriate reporting type based on the selected resources, while enabling multi-station data transmission when resources from different TRPs are identified.
Solution Approach 2:
The network device serves as an intermediary that receives both first and second measurement results and determines the final beam selection. This intermediary approach maintains reporting flexibility by allowing the terminal to report resources according to their TRP origin, while the network device coordinates the information to achieve accurate multi-station data transmission when needed.
