Dynamic RRM Measurement Selection in 5G Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless communication systems face challenges in efficiently managing radio resource management (RRM) measurements, particularly in scenarios where the reference signal received power and quality do not meet certain conditions, leading to suboptimal performance and increased energy consumption.
Innovation Solution
A method and apparatus for a user equipment (UE) in a wireless communication system, where the UE receives configuration information for a first signal and performs RRM measurements based on this signal if the reference signal received power and/or quality satisfy a predetermined condition. If the condition is not met, the UE performs RRM measurements based on a synchronization signal and physical broadcast channel block (SSB).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE performs RRM measurements based on the first signal when reference signal received power and quality satisfy certain conditions, then measurement accuracy is improved, but device complexity increases due to conditional judgment and multiple measurement modes
Solution Approach 1:
The patent implements dynamic measurement mode selection where the UE adapts between measuring the first signal and measuring SSB based on whether reference signal received power and quality conditions are satisfied. This dynamic adjustment optimizes measurement accuracy for different signal conditions while the network configures the measurement parameters to manage complexity.
Solution Approach 2:
The patent changes the measurement object parameter based on signal conditions - using the first signal (channel state information reference signal) when conditions are satisfied for higher accuracy, and switching to SSB when conditions are not satisfied. The network configures parameters such as reference signal received power thresholds and quality thresholds to control this parameter change.
2Measurement precision
If the UE always performs RRM measurements based on the first signal, then measurement accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic measurement mode selection where the UE adapts between measuring the first signal and measuring SSB based on whether reference signal received power and quality conditions are satisfied. This dynamic adjustment optimizes measurement accuracy for different signal conditions while the network configures the measurement parameters to manage complexity.
Solution Approach 2:
The patent changes the measurement object parameter based on signal conditions - using the first signal (channel state information reference signal) when conditions are satisfied for higher accuracy, and switching to SSB when conditions are not satisfied. The network configures parameters such as reference signal received power thresholds and quality thresholds to control this parameter change.
3Use of energy by moving object
If the UE performs RRM measurements based on SSB when reference signal received power and quality do not satisfy conditions, then energy consumption is reduced, but measurement accuracy deteriorates
Solution Approach 1:
The patent implements dynamic measurement mode selection where the UE adapts between measuring the first signal and measuring SSB based on whether reference signal received power and quality conditions are satisfied. This dynamic adjustment optimizes measurement accuracy for different signal conditions while the network configures the measurement parameters to manage complexity.
Solution Approach 2:
The patent changes the measurement object parameter based on signal conditions - using the first signal (channel state information reference signal) when conditions are satisfied for higher accuracy, and switching to SSB when conditions are not satisfied.
