Selective RRM Measurement Modes for Lower Terminal Power Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high power consumption of terminal equipment in 5G systems due to large bandwidth and high peak rates is a significant challenge, as existing RRM measurement methods do not adequately address power efficiency.
Innovation Solution
Implementing RRM measurement methods that allow terminal devices to select from multiple measurement modes based on first and second information configured for measurement, including RRM measurement on serving cells, intra-frequency, inter-frequency, and inter-RAT measurements, using various thresholds and channel conditions to optimize power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RRM measurement is performed continuously on all frequencies and cells, then measurement precision and network reliability are improved, but power consumption increases significantly
Solution Approach 1:
The patent applies partial action by performing RRM measurements selectively rather than continuously. The terminal device determines whether to perform measurements based on comparison between reference signal power and thresholds, executing measurements only when necessary to maintain network reliability while reducing unnecessary power consumption.
Solution Approach 2:
The patent changes the measurement parameter state from continuous to conditional. By introducing threshold-based decision-making, the system dynamically adjusts whether measurements are performed based on current signal conditions, thereby optimizing the balance between reliability and power consumption.
2Adaptability or versatility
If multiple measurement modes are supported for different scenarios, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic measurement modes where the terminal device can switch between different measurement behaviors based on current conditions. The system dynamically determines whether to perform intra-frequency, inter-frequency, or no measurements by comparing reference signal power against thresholds, providing adaptability without requiring complex pre-configured modes.
Solution Approach 2:
The patent segments the measurement process into distinct conditional paths. By dividing the measurement decision into separate evaluation stages (serving cell measurement, threshold comparison, mode determination), the system achieves versatility through modular decision-making rather than monolithic complex control.

AI summary
Disclosed are a method and device for RRM measurement. The power consumption of a terminal device can be reduced. The method comprises: determining a measurement mode for the RRM measurement in the following multiple measurement modes: performing the RRM measurement only on a serving cell of the terminal device; not performing the RRM measurement; performing intra-frequency measurement on the basis of first information configured for measurement; performing inter-frequency measurement or different system measurement on the basis of the first information configured for measurement; performing the intra-frequency measurement on the basis of second information configured for measurement; and performing the inter-frequency measurement or the different system measurement on the basis of the second information configured for measurement.
