UE QoE–MDT Reporting Alignment Without Frequent Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solutions for aligning Quality of Experience (QoE) and Minimization of Drive Tests (MDT) measurements in IDLE/INACTIVE states require the user equipment (UE) to establish connections with the serving base station every time a measurement session starts and stops, leading to significant power consumption and non-real-time reporting.
Innovation Solution
Techniques for aligning QoE and MDT measurements in IDLE and INACTIVE states without requiring frequent connection establishments, allowing the UE to report measurements efficiently by aligning them without active retrieval from the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE establishes connections with the serving base station every time a measurement session starts and stops, then measurement alignment between QoE and MDT is achieved, but power consumption increases significantly
Solution Approach 1:
The network entity pre-configures the UE with measurement parameters and reporting configurations before the UE enters IDLE or INACTIVE states. This preliminary configuration enables the UE to perform measurements and store results without needing to establish connections during state transitions, thereby achieving measurement alignment while reducing power consumption.
Solution Approach 2:
The network entity acts as an intermediary by providing advance measurement configurations and retrieving measurement results when the UE transitions back to CONNECTED states. This mediator approach eliminates the need for frequent connection establishments, resolving the contradiction between measurement alignment and power consumption.
2Measurement precision
If the UE establishes connections frequently for measurement reporting, then real-time measurement alignment is achieved, but network resources are consumed and latency increases
Solution Approach 1:
Measurement configurations are provided in advance before the UE enters IDLE or INACTIVE states, enabling the UE to perform and store measurements without waiting for connection establishment. This preliminary action reduces reporting latency while maintaining measurement alignment.
Solution Approach 2:
The UE continuously performs measurements and stores results in memory during IDLE and INACTIVE states, ensuring measurement data is ready for immediate reporting when the UE transitions back to CONNECTED states. This continuous measurement approach eliminates gaps and reduces overall reporting latency.
3Use of energy by moving object
If the UE reports measurements while in IDLE or INACTIVE states, then power consumption is reduced, but the network must handle asynchronous reporting without active retrieval
Solution Approach 1:
The UE autonomously performs measurements, stores results in memory, and determines when to report based on predefined configurations and state transitions. This self-service approach reduces power consumption by eliminating frequent network interactions while managing reporting complexity through pre-established rules.
Solution Approach 2:
The network entity provides feedback through pre-configured parameters that guide the UE's measurement and reporting behavior. The UE uses these configurations to determine when and how to report, creating a feedback-driven autonomous system that balances power savings with manageable complexity.

AI summary
Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE), generally including receiving, from a network entity, a configuration configuring the UE to report quality of experience (QoE) measurements and a configuration configuring UE to report logged minimization of drive tests (MDT), and indicating that the QoE reporting and logged MDT reporting are to be aligned and performing one or more actions, based on the indication, in order to align QoE reporting with logged MDT reporting.
