Static Attribute Relaxation Measurement for UE Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, devices with low mobility or in static positions face inefficient radio resource management (RRM) measurement processes, leading to increased power consumption and reduced endurance, as existing relaxation criteria do not adequately account for their specific conditions.
Innovation Solution
A relaxation measurement processing method and apparatus that allows user equipment (UE) to use a static attribute when satisfied, offering a greater relaxation degree than low mobility or non-cell edge criteria, thereby optimizing measurement processing based on static criteria indicated by the network device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If existing relaxation criteria (low mobility or non-cell edge) are used for RRM measurements, then measurement processing is performed with moderate relaxation, but power consumption remains high and endurance is reduced for static devices
Solution Approach 1:
The patent introduces a static attribute that allows devices to be identified and treated differently based on their mobility characteristics. Static devices receive a customized relaxation measurement scheme with higher relaxation degree, while mobile devices continue to use existing criteria. This localized differentiation resolves the contradiction by applying appropriate measurement strictness to each device type, reducing power consumption for static devices without compromising RRM measurement accuracy for mobile devices.
Solution Approach 2:
The patent changes the measurement parameters by introducing a static attribute and corresponding static criterion, which modifies the relaxation degree parameter. Devices with static attribute use a measurement scheme with higher relaxation degree (longer measurement period, fewer measurements) compared to existing criteria. This parameter change enables static devices to reduce power consumption while maintaining adequate RRM measurement accuracy through the customized scheme.
2Measurement precision
If RRM measurements are performed frequently to support UE mobility, then channel state accuracy is improved, but power consumption increases for static devices
Solution Approach 1:
The patent applies different measurement precision levels to different device types through the static attribute mechanism. Static devices use a relaxation measurement scheme with lower measurement frequency and fewer measurements, reducing power consumption. Mobile devices continue to use frequent measurements with existing criteria to maintain high channel state accuracy. This localized quality approach resolves the contradiction by matching measurement precision to actual device needs.
Solution Approach 2:
The patent implements partial action by allowing static devices to perform fewer RRM measurements than mobile devices. The static criterion enables these devices to use a relaxed measurement scheme that performs only essential measurements, rather than full frequent measurements. This partial action reduces power consumption for static devices while maintaining sufficient channel state accuracy for their immobile nature.
3Duration of action of moving object
If measurement relaxation is applied to reduce power consumption, then endurance is improved, but RRM measurement accuracy may deteriorate
Solution Approach 1:
The patent introduces static attribute information that enables the network device to identify devices suitable for measurement relaxation. Static devices receive a customized relaxation measurement scheme that provides higher relaxation degree, improving endurance. Mobile devices continue to use existing criteria without relaxation. This localized quality approach ensures that measurement accuracy is maintained for mobile devices while endurance is improved for static devices through targeted relaxation.
Solution Approach 2:
The patent implements feedback through the static attribute mechanism, where the network device determines whether a device has static attribute and configures the appropriate measurement scheme accordingly. The network device receives feedback about device characteristics and adjusts the measurement relaxation level to maintain adequate RRM measurement accuracy while improving endurance for eligible static devices.
