Wireless Device Transmission Mode Testing via Switching Range Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current testing methods for wireless communication devices fail to effectively examine switching procedures between transmission states, particularly in modern transmission standards, and do not provide clear definitions for switching points, leading to unknown and undefined decision processes regarding transmission state adjustments.
Innovation Solution
A method that establishes a switching range in a parameter space to generate random parameter points according to a defined probability distribution, transmitting signals with varying transmission qualities to the device under test, and evaluating response signals for recommendations or adjusted transmission states, thereby analyzing hysteresis effects and directionalities between transmission states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If classic testing methods measure transmission rate at constantly improved transmission quality, then transmission rate measurement is simple, but switching procedures between transmission states cannot be examined
Solution Approach 1:
The patent applies dynamics by introducing time-varying transmission quality functions that simulate real channel conditions, allowing the test to dynamically transition between different transmission states rather than measuring at static quality levels. This enables observation of switching procedures while maintaining operational simplicity through automated simulation.
Solution Approach 2:
The patent uses preliminary action by pre-defining multiple transmission states and their associated transmission quality characteristics before testing. The test device is pre-configured with state transition criteria and hysteresis parameters, allowing automatic examination of switching procedures without manual intervention during the test execution.
2Adaptability or versatility
If Monte Carlo method simulates fading oscillations, then transmission quality fluctuations are simulated, but switching points remain unknown and undefined
Solution Approach 1:
The patent implements feedback by continuously monitoring the transmitted signal quality and comparing it against predefined thresholds for different transmission states. The test device receives feedback about actual state transitions and uses this information to precisely identify switching points, resolving the ambiguity present in Monte Carlo simulations.
Solution Approach 2:
The patent replaces the random Monte Carlo simulation approach with a controlled measurement system that systematically varies transmission quality and directly observes switching behavior. This substitution of measurement methodology provides precise, deterministic identification of switching points rather than relying on statistical simulation.
3Stability of the object's composition
If hysteresis effect prevents constant switching, then transmission state stability is improved, but switching point clarity is reduced
Solution Approach 1:
The patent applies segmentation by dividing the transmission quality range into distinct zones corresponding to different transmission states, with clear boundary definitions. By segmenting the measurement process into discrete quality levels and observing transitions between them, the patent achieves both stability through hysteresis and clarity in identifying switching points at the segment boundaries.

AI summary
A method for testing transmission modes of a wireless communication device. According to the method, a switching range is determined in a parameter space in a test device. The parameter of the parameter space describes the quality of transmission and influences a recommendation for a transmission mode to be adjusted in a device to be tested. The switching range is a subspace of the parameter space and contains at least one switching limit for the recommendation for the subsequent transmission mode to be adjusted. In a further step, random parameter points from the switching range are generated depending on a probability distribution which is defined for the switching range. A signal is generated for every parameter point and has a transmission mode determined by the parameter point and is transmitted to the device to be tested. The device to be tested then transmits one response signal per received signal to the test device, the response signal containing a recommendation for a subsequent transmission mode to be adjusted. All recommendations from all received response signals are evaluated in the test device.
