Capability-Based Access Thresholds for NR-Lite Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies, such as those used in 5G NR, fail to accommodate reduced capability UE (NR-lite) due to uniform communication parameter thresholds, leading to poor access performance for terminals with lower capabilities.
Innovation Solution
Implementing differentiated communication parameter thresholds and offsets based on terminal capabilities, such as RSRP, to enhance access success rates for NR-lite terminals.

Engineering Contradiction Analysis
1Device complexity
If uniform communication parameter thresholds are used for all terminals, then network complexity is reduced, but access performance for low-capability terminals deteriorates
Solution Approach 1:
The patent segments terminals into different capability types (normal capability and reduced capability) and assigns different communication parameter thresholds to each type. This segmentation allows the network to treat different terminal categories differently, improving access performance for reduced capability terminals without significantly increasing overall network complexity through structured threshold management.
Solution Approach 2:
The patent applies local quality by configuring specific communication parameters (such as RSRP thresholds, message size limits, timing advance values) tailored to the local characteristics of reduced capability terminals. This ensures that each terminal type receives parameters optimized for its specific capabilities, thereby improving access performance while maintaining manageable network complexity through targeted parameter configuration.
2Reliability
If communication parameters are tailored to terminal capabilities, then access performance for reduced capability terminals improves, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling reduced capability terminals to autonomously identify their capability type and select appropriate communication parameters from predefined sets. Terminals with reduced capability can self-configure their communication behavior based on their inherent limitations, reducing the need for complex network-side configuration and management while improving access performance.
Solution Approach 2:
The patent manages device complexity through parameter changes by adjusting key communication parameters (message size, timing advance, RSRP thresholds) to match terminal capabilities. Rather than redesigning the entire communication protocol, the system achieves improved access performance by modifying specific parameters to suit reduced capability terminals, thereby limiting the increase in device complexity to only the necessary parameter adjustments.
