Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base stations use higher modulation and coding schemes to improve throughput when SINR is high, then data rate increases, but connection stability decreases due to signal distortions and interference
Solution Approach 1:
The device dynamically adjusts the reported SINR value as a parameter to manipulate base station configuration. By changing the reported signal quality parameter, the device influences the base station's modulation and coding scheme selection to achieve desired connection stability and data rate requirements.
Solution Approach 2:
The system uses feedback mechanisms where the device reports signal quality metrics to the base station, which then adjusts transmission parameters accordingly. The deceptive feedback about SINR values creates a feedback loop that results in more stable connections while maintaining acceptable data rates.
2Reliability
If base stations adjust transmission parameters to maintain reliability level, then connection stability improves, but spectral efficiency and data rate decrease
Solution Approach 1:
The device changes the reported signal quality parameter (SINR) to manipulate the base station's transmission parameter selection. This parameter manipulation allows the system to achieve both reliability and spectral efficiency by influencing the base station to select appropriate modulation and coding schemes.
Solution Approach 2:
The system dynamically adjusts the reported SINR values based on actual connection conditions and requirements. This dynamic parameter adjustment allows the base station to optimize transmission parameters in real-time, balancing reliability and spectral efficiency according to current network conditions.
3Measurement precision
If devices transmit accurate signal quality data to base stations, then base station configuration accuracy improves, but connection stability decreases due to signal distortions
Solution Approach 1:
Instead of reporting accurate signal quality measurements, the device inverts the approach by reporting manipulated SINR values. This inversion of the conventional reporting mechanism allows the system to achieve better connection stability by causing the base station to select more conservative transmission parameters.

AI summary
Techniques for optimizing connection stability via communications with base stations in wireless communication networks. A current actual signal-to-distortion measurement value is determined for signals received by a device from a base station in a wireless communication network. A target base station configuration is determined based on the actual signal-to-distortion measurement value and known relationships between signal-to-distortion measurements and reliability metrics corresponding to different base station configurations. Deceptive signal quality transmissions are sent to the base station until the base station selects the target base station configuration. The deceptive signal quality transmissions may include deceptive signal-to-distortion measurements or deceptive binary values indicating poor signal quality. In various embodiments, the target base station configuration is determined based further on a required data rate such that signals transmitted using the target base station configuration meet the required data rate.
