Group-Based Report Configuration for 5G Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in efficiently managing group-based reports when at least one channel measurement resource set is configured with repetition, leading to conflicts and suboptimal beam management.
Innovation Solution
The implementation of a method where user equipment (UE) and network entities configure group-based reports with specific repetition settings for multiple transmission-reception points (TRPs), allowing for simultaneous beam reception and measurement reporting, while excluding beam identifiers and signal strength measurements for CMR sets configured with repetition ON, to optimize communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If group-based reports include beam identifiers and signal strength measurements for all CMR sets, then measurement precision is improved, but report overhead increases
Solution Approach 1:
The patent extracts beam identifiers and signal strength measurements from CMR sets configured with repetition and excludes them from group-based reports. This selective extraction resolves the contradiction by removing redundant information that would increase overhead while maintaining precision for non-repeated CMR sets.
Solution Approach 2:
The patent applies partial action by including beam measurement information only for CMR sets without repetition configuration, rather than for all CMR sets. This partial inclusion optimizes the balance between measurement precision and report overhead by avoiding excessive reporting of redundant data.
2Reliability
If beam identifiers are included for CMR sets with repetition, then beam management completeness is improved, but report complexity increases
Solution Approach 1:
The patent removes beam identifiers from CMR sets configured with repetition, extracting only the necessary measurement data for non-repeated sets. This simplifies the report structure while maintaining beam management reliability for the essential configurations.
3Loss of information
If all CMR sets are measured and reported, then information completeness is improved, but processing time increases
Solution Approach 1:
The patent extracts and excludes measurement data from CMR sets with repetition, reducing the total volume of measurements that need to be processed and reported. This maintains information completeness for critical non-repeated sets while reducing processing time overall.
Solution Approach 2:
The patent performs measurements on all CMR sets but only reports results for non-repeated sets, applying partial reporting action. This approach maintains measurement completeness for decision-making while reducing the time-consuming reporting process.

AI summary
Apparatus, methods, and computer-readable media for facilitating group-based reports when at least one CMR set associated with the group-based report is configured with repetition ON are disclosed herein. An example method for wireless communication at a UE includes receiving a configuration for a group-based report associated with multiple TRPs, each TRP of the multiple TRPs associated with a respective CMR set including one or more beams. The example method also includes receiving reference signals via the one or more beams associated with each CMR set. The example method also includes transmitting the group-based report based on measurements associated with the reference signals and the configuration, the group-based report including a first quantity of report groups, a second quantity of beams per report group.
