Terminal 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, leading to inefficiencies in resource measurement and communication.
Innovation Solution
A resource measurement method that allows a terminal to receive and report measurement results indicating resources that can be simultaneously received from multiple TRPs, enabling simultaneous data transmission across different TRPs by selecting and reporting resources within configured resource sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional beam selection method is used, then terminal can report two resources that can be simultaneously received, but the two beams may belong to the same TRP, failing to achieve multi-station data transmission
Solution Approach 1:
The patent divides the resource configuration into multiple resource sets (first resource set, second resource set, etc.), where each resource set corresponds to a different TRP. The terminal selects resources from different resource sets to ensure beams from different TRPs are chosen, enabling multi-station data transmission while maintaining accurate beam selection through structured measurement reporting.
2Adaptability or versatility
If resource measurement is performed to select beams from different TRPs, then multi-station data transmission can be enabled, but the measurement and reporting process becomes more complex
Solution Approach 1:
The patent uses a unified measurement reporting mechanism that handles both single TRP and multi-TRP scenarios through the same framework. The terminal reports measured resources with their corresponding TRP identifiers, and the network device processes these reports using consistent logic, simplifying the overall system complexity while enabling versatile multi-station data transmission capability.

AI summary
This application provides a resource measurement method and an apparatus. A terminal receives measurement configuration information including N resource sets, and determines, based on a value of N, to send a first measurement result or a second measurement result to a network device. Specifically, the terminal sends the first measurement result to the network device when N>1, where the first measurement result is used to indicate m resources, downlink signals corresponding to the m resources can be simultaneously received by the terminal, and the m resources are in a one-to-one correspondence with m resource sets in the N resource sets. The terminal sends the second measurement result to the network device when N=1.
