Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional techniques are used for handling collocated wireless radios, then device complexity is reduced, but isolation between transceivers deteriorates causing power leakage and signal corruption
Solution Approach 1:
The patent implements dynamic transceiver management by continuously monitoring channel conditions and adaptively adjusting transmission parameters (power levels, modulation schemes, timing) for each transceiver based on real-time interference measurements, transforming static conventional techniques into a dynamic system that optimizes isolation performance
Solution Approach 2:
The system changes multiple transmission parameters simultaneously including power spectral density, symbol timing, and modulation depth based on measured interference levels, allowing each transceiver to adapt its parameters to minimize mutual interference while maintaining communication quality
2Reliability
If isolation techniques are implemented to reduce power leakage, then transceiver coexistence improves, but data throughput decreases
Solution Approach 1:
The patent applies partial isolation techniques selectively to specific frequency bands and time periods where interference occurs, rather than implementing complete isolation across all transmissions, thereby maintaining high throughput in non-interfering channels while providing targeted coexistence enhancement where needed
Solution Approach 2:
The system dynamically adjusts transmission parameters such as power spectral density and symbol timing to optimize the trade-off between isolation and throughput, changing parameters in real-time based on measured channel conditions to maintain maximum data rate while ensuring acceptable coexistence performance
3Productivity
If transmit power is increased to maintain throughput, then data rate is preserved, but power leakage between transceivers increases
Solution Approach 1:
The patent implements dynamic power control that continuously monitors both throughput requirements and interference levels, adjusting transmit power in real-time to provide minimum necessary power for maintaining data rate while minimizing excess power that would cause leakage to other transceivers
Solution Approach 2:
The system changes power spectral density distribution across frequency bands based on measured interference patterns, concentrating power in frequencies with less interference and reducing power in frequencies where other transceivers operate, thereby maintaining throughput while reducing overall power leakage

AI summary
Systems, methods, and devices enhance performance of collocated transceivers in wireless devices. Methods include determining, using a processing device comprising processing elements, a transmit power for a first transceiver of a wireless device, and determining, using the processing device, a coding rate for a second transceiver of the wireless device based, at least in part, on the determined transmit power, the first transceiver being collocated with the second transceiver. Methods also include determining, using the processing device, a transmission rate for the second transceiver based, at least in part, on the determined coding rate.
