Beam Based Criteria Evaluation for RRM Measurement Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio resource management (RRM) procedures in 3GPP radio access networks struggle to efficiently determine when a user equipment (UE) can relax its RRM measurements, leading to potential power consumption issues and unreliable mobility performance.
Innovation Solution
The proposed solution involves determining a reference value based on measurements to evaluate beam change conditions, and using a timer to assess whether these conditions have been fulfilled, thereby enabling the UE to adapt its RRM measurements and power saving operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RRM measurements are performed continuously to ensure reliable mobility performance, then measurement reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adaptation of RRM measurement frequency based on mobility state detection. The UE continuously monitors beam changes and adjusts measurement periodicity accordingly - performing measurements frequently when mobility is detected and reducing measurement frequency when stationary, thus resolving the contradiction between reliability and power consumption
Solution Approach 2:
The patent changes the measurement parameter frequency based on detected beam stability. When beam changes are detected, the system increases measurement frequency; when beams remain stable, it reduces frequency. This parameter adaptation allows the system to maintain reliability when needed while saving power during stable conditions
2Use of energy by moving object
If RRM measurement relaxation is applied to save power, then power consumption is reduced, but measurement reliability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the UE continuously monitors beam changes and uses this information to adjust measurement relaxation levels. The feedback loop ensures that relaxation is applied only when appropriate (stable beam conditions) and automatically adjusted when mobility is detected, maintaining reliability while saving power
Solution Approach 2:
The patent performs preliminary beam stability assessment before applying measurement relaxation. By evaluating beam change conditions in advance, the system determines whether relaxation can be safely applied without compromising mobility performance, thus maintaining reliability while reducing power consumption
3Reliability
If beam change conditions are evaluated continuously to improve adaptation accuracy, then adaptation reliability is improved, but processing complexity increases
Solution Approach 1:
The patent implements periodic evaluation of beam change conditions rather than continuous complex analysis. The system performs assessments at specific intervals or triggered by significant events (beam changes), reducing processing complexity while maintaining adequate adaptation accuracy for mobility management
