Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in decoding quality of experience (QoE) measurements performed by user equipment (UE) due to format incompatibilities, leading to inefficiencies in RAN performance enhancement.
Innovation Solution
UEs and base stations communicate UE capabilities for QoE measurements, enabling RAN decodability through configuration and reporting mechanisms, allowing for enhanced RAN performance by adjusting QoE measurement parameters.

Engineering Contradiction Analysis
1Measurement precision
If QoE measurement information is transmitted in a format optimized for UE internal processing, then measurement precision is improved, but the RAN cannot decode the measurement parameters
Solution Approach 1:
The QoE measurement information is segmented into two distinct parts: RAN decodable parameters that can be decoded by the base station for network optimization, and non-decodable parameters that maintain full measurement precision but are only processable by the UE. This segmentation allows both requirements to coexist by separating the information stream into decodeable and non-decodeable components.
Solution Approach 2:
A configuration mechanism acts as an intermediary between the UE and RAN, enabling the UE to indicate its QoE measurement capabilities and the RAN to configure appropriate parameters. This intermediary configuration process ensures that the RAN receives decodable parameters while the UE maintains access to precise measurement data through capability indication and configured parameter reporting.
2Measurement precision
If the RAN configures QoE measurements with detailed parameters, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The UE performs preliminary capability indication before actual QoE measurement configuration, informing the RAN of its supported measurement types and capabilities. This preliminary action allows the RAN to configure only those detailed parameters that the UE can handle, avoiding unnecessary complexity while maintaining measurement precision for supported features.
Solution Approach 2:
The QoE measurement configuration is made dynamic and adaptive based on UE capabilities. The system transitions from static, one-size-fits-all configuration to dynamic capability-based configuration, where the RAN adjusts measurement parameters according to the specific UE's indicated capabilities, reducing complexity for devices with limited functionality while enabling detailed measurements for capable devices.
3Loss of information
If the UE reports all QoE measurement data, then information completeness is improved, but loss of time in transmission and processing increases
Solution Approach 1:
The RAN extracts and processes only the essential decodable parameters from the QoE measurement report for immediate network optimization decisions. By taking out only the critical information needed for RAN performance enhancement rather than processing all measurement data, the system maintains information completeness for network control while significantly reducing processing and transmission time.
Solution Approach 2:
The system applies partial action by having the RAN process only the subset of QoE parameters that are decodable and relevant for radio access network optimization, rather than processing all possible measurement parameters. This partial processing approach maintains sufficient information completeness for RAN performance improvement while minimizing time loss in transmission and processing.

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for handling of QoE measurements. In aspects, a UE may transmit, to a base station, an indication of one or more UE capabilities for at least one of multiple instances or simultaneous instances of one or more QoE measurements at the UE associated with one or more types of services, and receive, from the base station, a QoE measurement information configuration for the QoE measurement information associated with the one or more types of services based on the indication that of the one or more UE capabilities.
