Terminal Device Dynamic RRM Measurement Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communications devices, particularly those using 5G or NR networks, face high power consumption due to frequent Radio Resource Management (RRM) measurements across multiple frequencies, which reduces battery life and increases energy usage unnecessarily.
Innovation Solution
Implementing conditions based on signal strength (RSRP) thresholds to determine when specific RRM measurements should be performed, allowing devices to adjust the frequencies and nodes measured, thereby reducing redundant measurements and conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent RRM measurements across multiple frequencies are performed, then connection reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of measurement configurations based on real-time network conditions. The terminal device modifies measurement parameters such as measurement objects, reporting configurations, and measurement intervals according to current signal strength and network state, transitioning from static to dynamic measurement strategies that balance reliability and power consumption.
Solution Approach 2:
The patent changes key measurement parameters including measurement objects, reporting configurations, and measurement intervals based on network conditions. By adjusting these parameters dynamically, the system optimizes the balance between maintaining connection reliability and reducing power consumption during different operational states.
2Adaptability or versatility
If RRM measurements are performed across multiple frequencies, then network adaptability is improved, but redundant measurements increase power consumption
Solution Approach 1:
The patent applies local quality by measuring only the specific frequencies and cells that are actually needed based on current network conditions and terminal location. Instead of uniformly measuring all frequencies, the system identifies and measures only the relevant subset, reducing redundant measurements while maintaining necessary network adaptability.
Solution Approach 2:
The patent implements partial action by performing RRM measurements only on a subset of frequencies and cells rather than all possible frequencies. The system determines the minimum necessary measurements required for network adaptability, avoiding excessive or redundant measurements that would waste power.
3Use of energy by moving object
If measurement constraints are adjusted based on signal strength thresholds, then power consumption is reduced, but measurement accuracy may be compromised
Solution Approach 1:
The patent implements feedback mechanisms where measurement results and network conditions are continuously monitored and used to adjust measurement configurations. This feedback loop ensures that measurement accuracy is maintained by adapting measurement strategies based on real-time signal strength and network state information.
Solution Approach 2:
The patent applies preliminary action by pre-configuring measurement constraints and thresholds before actual measurements occur. The system prepares measurement configurations in advance based on predicted network conditions, allowing efficient measurement execution while maintaining accuracy through pre-established criteria.
