Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack an efficient method to determine optimal beam tracking frequencies based on signal-to-noise ratios (SNRs), leading to suboptimal power savings and performance in maintaining radio links, especially for UEs with varying SNR conditions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam tracking frequency is increased to maintain radio link reliability, then reliability improves, but power consumption increases
Solution Approach 1:
The patent implements dynamic beam tracking frequency adjustment based on SNR conditions. The UE determines beam tracking frequencies adaptively according to detected SNR levels, transitioning from static to dynamic operation. This resolves the contradiction by making the system flexible - using higher frequencies only when necessary (low SNR) and lower frequencies when conditions permit (high SNR), thus maintaining reliability while optimizing power consumption.
Solution Approach 2:
The patent changes the operational parameters (beam tracking frequency) based on detected SNR conditions. Different frequency values are selected from a set of possible frequencies according to the current channel quality. This parameter adaptation allows the system to achieve reliable communication when needed while conserving energy during favorable conditions, directly resolving the reliability-power consumption tradeoff.
2Use of energy by moving object
If beam tracking frequency is decreased to save power, then power savings improve, but radio link maintenance deteriorates
Solution Approach 1:
The system dynamically adjusts beam tracking frequency based on real-time SNR detection. When SNR is high, the frequency is reduced to maximize power savings. When SNR degrades, the frequency increases to maintain link reliability. This dynamic response resolves the contradiction by ensuring power savings are achieved without compromising reliability, as the system only reduces frequency when conditions permit.
Solution Approach 2:
The patent implements parameter changes in beam tracking frequency based on SNR thresholds. The UE selects from multiple frequency parameters according to detected channel conditions, ensuring that power-saving low-frequency operation is used only when reliability requirements are satisfied by current SNR levels, thus resolving the tradeoff between power savings and link maintenance.
3Device complexity
If a single beam tracking frequency is used for all SNR conditions, then device complexity is reduced, but performance optimization deteriorates
Solution Approach 1:
The patent segments the SNR operating range into multiple conditions (e.g., high SNR, medium SNR, low SNR), each associated with a different beam tracking frequency. This segmentation allows the system to maintain relatively simple operation within each segment while achieving overall performance optimization across all conditions, resolving the contradiction between complexity and optimization.
Solution Approach 2:
The patent employs multiple frequency parameters selected based on SNR conditions rather than using a single fixed frequency. This parameter diversity enables performance optimization across varying channel conditions while maintaining manageable complexity through systematic parameter selection based on detected SNR levels, thus resolving the contradiction between simplicity and optimization.
