Radio Device Transmission Mode Testing via Channel Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing transmission states in wireless communication devices are indirect and lack specific evaluation of switching points and occurrence rates, making it difficult to determine the correctness of transmission state adjustments and adaptation speed.
Innovation Solution
A method that establishes a channel quality for testing, allowing for direct evaluation of transmission states by sending data through a test device, receiving decision information, and comparing it to expected states to assess correctness, enabling precise adjustment and analysis of switching behaviors and adaptation speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If indirect measurement methods using data rate are used to test transmission states, then the testing process is simple to implement, but the measurement precision and information quality are insufficient
Solution Approach 1:
Instead of inferring transmission states indirectly from data rate, the patent inverts the approach by directly measuring transmission quality parameters (such as signal-to-noise ratio, bit error rate, packet error rate) and using these direct measurements to determine transmission states. This inversion from indirect inference to direct measurement resolves the contradiction by providing both implementation feasibility and high measurement precision.
2Device complexity
If indirect measurement methods are used, then the testing complexity is low, but the ability to evaluate switching points and occurrence rates is insufficient
Solution Approach 1:
The patent segments the transmission quality assessment into multiple independent measurable parameters (signal-to-noise ratio, bit error rate, packet error rate, transmission state identification). By dividing the complex evaluation into these discrete segments, the system can precisely track switching points between transmission states and calculate occurrence rates, thereby reducing information loss while maintaining manageable testing complexity.
3Ease of manufacture
If data rate measurement is used, then the testing method is simple, but the occurrence rate of transmission state changes cannot be determined
Solution Approach 1:
The patent implements a feedback mechanism where transmission quality parameters are continuously measured and fed back to identify transmission state changes. By monitoring parameters like bit error rate and signal-to-noise ratio over time and comparing them against threshold values, the system can detect when transmission states change and calculate the occurrence rates of these changes, thereby preserving critical information that would be lost in simple data rate measurement.
4Ease of operation
If indirect testing methods are used, then the testing process is straightforward, but specific problem regions and switching points cannot be tested individually
Solution Approach 1:
The patent applies local quality by enabling independent testing and evaluation of specific transmission quality parameters and switching points. Rather than treating all transmission states uniformly, the system can focus measurements on particular problem regions (such as specific switching points between transmission modes) by adjusting measurement thresholds and parameters locally, thereby achieving both ease of operation and precise specific evaluation capability.

AI summary
A method for determining a channel quality for the transmission of data in the channel by a test device. The test device transmits the data with the determined channel quality to a device to be tested which determines one or more pieces of decision information. The device to be tested forwards the piece(s) of decision information to the test device as a response signal and the test device reads the piece(s) of decision information from the response signal. The piece(s) of decision information from the response signal is/are uniquely attributed to a transmission mode to be adjusted. The initially determined channel quality is also uniquely attributed to an expected transmission mode. The expected transmission mode is compared with the transmission mode to be adjusted in a comparative unit in the evaluation unit, thereby allowing a statement regarding the correctness of the transmission mode to be adjusted.
