Terminal Measurement Method for Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current measurement methods in communication technologies are not conducive to power saving for terminals, as they require unnecessary measurements across all detected cells and frequencies, leading to increased power consumption.
Innovation Solution
Implementing a measurement method where neighboring cell and/or inter-frequency measurements are performed only when specific cells or frequencies satisfy a measurement condition, with the results being selectively reported to the network side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal performs measurement on all cells detected on a frequency corresponding to the measurement configuration or on all cells of a neighboring cell list, then the measurement coverage is improved, but the power consumption increases
Solution Approach 1:
The patent segments the measurement process by dividing cells into different categories (serving cell, neighboring cells, etc.) and frequencies into different groups. The terminal performs measurements selectively on specific segments (e.g., only on cells that satisfy certain conditions or on specific frequency groups) rather than on all cells and frequencies, thereby reducing overall power consumption while maintaining necessary measurement coverage.
Solution Approach 2:
The patent applies partial action by having the terminal perform measurements only on a subset of cells and frequencies that are deemed necessary based on predefined conditions, rather than performing exhaustive measurements on all detected cells and frequencies. This partial measurement approach reduces power consumption while still providing sufficient measurement data for network operations.
2Measurement precision
If the terminal performs measurement on all cells and frequencies, then the measurement completeness is improved, but the power saving is reduced
Solution Approach 1:
The patent segments the measurement task by categorizing cells and frequencies, and selectively performing measurements only on relevant segments. For example, the terminal may prioritize measurements on cells that are likely to be handover targets or on frequencies that are configured for specific purposes, thereby achieving sufficient measurement completeness with reduced energy expenditure.
Solution Approach 2:
The patent changes measurement parameters dynamically based on terminal state and network conditions. For stationary or low-speed moving terminals, the measurement frequency and scope are reduced compared to high-speed moving terminals. This parameter adjustment allows the system to maintain measurement completeness when necessary while maximizing power saving when terminal movement and network conditions permit.
