Beam Measurement Reporting in MDT Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for Immediate Minimization of Drive Tests (MDT) in wireless communication networks lack effective beam level measurement reporting, limiting the ability to build accurate coverage maps and analyze Quality of Service (QoS) performance at the beam level.
Innovation Solution
A method where a network node provides instructions to a User Equipment (UE) for reporting beam measurements as part of existing MDT configurations, allowing the network node to collect and append cell quality derivation parameters to the measurement reports, enabling the construction of beam level coverage maps without requiring additional measurements or changes to the RRC protocol specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam level measurement reporting is implemented, then measurement precision and QoS analysis capability are improved, but device complexity and protocol complexity increase
Solution Approach 1:
The patent reuses existing RRC measurement configuration and reporting procedures for beam level measurements, making the existing protocol framework multi-functional. Instead of creating dedicated beam measurement protocols, the solution extends the universality of existing RRC procedures to handle both traditional cell-level and beam-level measurements, thereby improving measurement precision without proportionally increasing protocol complexity
Solution Approach 2:
The patent introduces beam level measurement capabilities by modifying measurement parameters within the existing RRC framework. Specifically, it extends measurement objects to include beam-specific parameters and enhances reporting configurations to accommodate beam level data, achieving improved measurement precision through parameter extensions rather than protocol restructuring
2Measurement precision
If beam level measurement reporting is configured, then coverage map accuracy is improved, but loss of time for measurement collection and processing increases
Solution Approach 1:
The patent merges beam level measurement collection with existing MDT (Minimization of Drive Tests) procedures. By combining beam measurements with traditional cell-level MDT measurements into a unified collection and reporting framework, the solution improves coverage map accuracy while avoiding the time penalty of completely separate measurement procedures. The merged approach allows simultaneous collection of multiple measurement types through existing MDT infrastructure
3Loss of information
If multiple measurement parameters are collected, then information completeness is improved, but loss of information due to processing complexity increases
Solution Approach 1:
The patent introduces an intermediary processing layer at the network side that handles the complexity of multiple beam measurement parameters. The intermediary component (network node) receives raw beam measurement data from UEs, performs the complex processing of correlating location information with beam measurements, and generates processed results. This intermediary approach allows complete information collection while centralizing the processing complexity away from the UE, thereby maintaining information completeness without overwhelming individual devices

AI summary
The present disclosure relates to a method performed by a network node for handling of one or more beam measurements in a communications system. The network node obtains information associated with a report configuration for one or more beam measurements from another node. Based on the obtained information, the network node provides, to a UE, instructions on how to provide a report of the one or more beam measurements to the network node. The network node obtains, from the UE and according to the instructions, the report of the one or more beam measurement, wherein the report includes information associated with executed one or more beam measurements.
