RedCap UE Parameter Reporting for SON and MDT Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems do not effectively accommodate reduced capability user equipment (RedCap UEs) by configuring them for self-organizing network (SON) and minimization of drive tests (MDT) procedures, leading to inefficient network adjustments and communication failures.
Innovation Solution
RedCap UEs are enabled to report their reduced capabilities to the base station, allowing the base station to configure appropriate SON/MDT reporting parameters, adjusting network settings based on these capabilities to enhance communication reliability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing parameter reporting procedures are used for all UEs, then network coverage and basic communication are maintained, but resource allocation efficiency deteriorates and communication reliability worsens due to not accounting for varying UE capabilities
Solution Approach 1:
The patent applies local quality by configuring parameter reporting procedures differently for reduced capability UEs compared to normal UEs. The base station identifies reduced capability UEs through capability indicators and applies tailored reporting configurations (e.g., adjusted measurement logging intervals, event triggers, and reporting quantities) specifically to these devices, rather than using a uniform approach for all UEs. This resolves the contradiction by improving reliability for reduced capability UEs through specialized handling while maintaining efficient resource allocation through capability-based differentiation.
2Reliability
If uniform parameter reporting is applied to all UEs, then system complexity is minimized, but communication reliability deteriorates for reduced capability UEs
Solution Approach 1:
The patent implements parameter changes by modifying reporting configuration parameters (measurement logging intervals, event triggers, reporting quantities) based on UE capability indicators. When a reduced capability UE is detected, the base station adjusts these parameters to match the device's processing and memory constraints, thereby improving communication reliability for these devices without requiring a complete redesign of the reporting system.
Solution Approach 2:
The patent applies dynamics by making the parameter reporting configuration adaptive rather than static. The base station dynamically determines reporting parameters based on received capability indicators from UEs, allowing the system to flexibly adjust configurations to match each UE's actual capabilities. This dynamic approach improves reliability for reduced capability UEs while keeping overall system complexity manageable through automated capability-based differentiation.
3Productivity
If reduced capability UEs use standard reporting intervals and parameters, then configuration simplicity is maintained, but resource usage efficiency deteriorates and latency increases
Solution Approach 1:
The patent applies local quality by implementing capability-specific reporting configurations. The base station identifies reduced capability UEs through capability indicators and applies optimized reporting parameters tailored to these devices' constraints, such as adjusted measurement logging intervals and event triggers. This improves resource usage efficiency for reduced capability UEs by matching configuration complexity to actual device capabilities rather than applying uniform standards to all devices.

AI summary
Methods, systems, and devices for wireless communications are described for capability indications by a reduced capability user equipment (UE) and UE-based performance measurement parameter reporting or self-organizing network (SON) parameter reporting based on the capability indications. A reduced capability UE may transmit a set of capabilities to a base station that indicate various types of parameter reporting that are supported at the UE. The base station may identify the UE as a reduced capability device, and set one or more reporting parameters based on the indicated UE capabilities. The base station may provide a reporting configuration to the UE with the one or more reporting parameters, and the UE may provide reporting of measured parameters (e.g., performance measurement parameter reporting or SON parameter reporting) based on the reporting configuration.
