TRP Candidate Identification via UE Measurement Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of identifying and selecting multi-transmit receive points (TRPs) in wireless communications systems is inefficient, leading to suboptimal communication quality and service delivery in multi-TRP environments.
Innovation Solution
A method and system where user equipment (UE) performs measurements on associated TRPs, determines candidate TRPs based on these measurements, and transmits a report to the base station, which then selects the most suitable TRPs for communication, optimizing signal quality and timing characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station uses traditional TRP selection methods, then the system can maintain simple operation, but the TRP identification process is inefficient and communication quality is suboptimal
Solution Approach 1:
The UE autonomously performs measurements on multiple TRPs and autonomously identifies candidate TRPs based on measurement results, eliminating the need for the base station to directly select TRPs. This self-service approach improves identification efficiency while keeping base station operations simple.
Solution Approach 2:
The UE performs measurements and identifies candidate TRPs in advance before actual communication occurs. The base station only needs to receive the pre-identified candidate list and make a final selection, which streamlines the overall process and improves efficiency.
2Reliability
If the UE performs comprehensive measurements on all TRPs, then the communication quality and signal characteristics are optimized, but the measurement and reporting overhead increases
Solution Approach 1:
The patent extracts only the necessary measurement information and candidate TRP identifiers from the full set of measurements. Instead of reporting all measurement data, the UE identifies and reports only the candidate TRPs that meet certain criteria, reducing overhead while maintaining communication quality.
Solution Approach 2:
The patent changes the reporting parameter from comprehensive measurement data to a simplified candidate TRP list. This parameter transformation reduces the amount of information that needs to be transmitted while preserving the essential information needed for quality communication.
3Measurement precision
If the base station selects TRPs based on detailed UE measurements, then the TRP selection accuracy is improved, but the system complexity and processing requirements increase
Solution Approach 1:
The UE performs measurements on more TRPs than strictly necessary, identifying a list of candidate TRPs that exceeds the minimum requirement. The base station then selects from this pre-filtered candidate list, which reduces the base station's processing complexity while maintaining selection accuracy.
Solution Approach 2:
The candidate TRP list acts as an intermediary between the UE's comprehensive measurements and the base station's final selection. This intermediate structure preserves measurement precision information while simplifying the base station's decision-making process.

AI summary
Methods, systems, and devices for multi-transmit receive point candidate identification are described. A base station may indicate, to a user equipment (UE), one or more measurements to be performed on multiple transmit receive points (TRPs) for determination of TRP candidates for communications between the UE and the base station. The UE may perform the measurements on each of the TRPs, and transmit a report to the base station that is based on the measurements. The report may be associated with the TRP candidates. The base station may select one or more of the TRP candidates for communications with the UE, and may indicate the selected TRP candidates to the UE.
