Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fine antenna training is performed to achieve high data rates, then data rate is improved, but protocol complexity and training overhead increase
Solution Approach 1:
The patent segments the antenna training process into distinct phases: coarse training using sector beams to establish initial directionality, followed by fine training using more precise beamforming. This segmentation allows the system to achieve high data rates through fine training while managing protocol complexity by structuring the training sequence in organized stages with different levels of precision.
2Measurement precision
If frequent antenna training is performed for mobile devices to maintain directionality, then directionality accuracy is improved, but training overhead and time consumption increase
Solution Approach 1:
The patent implements periodic antenna training where devices perform coarse training at regular intervals to update their directional parameters. Between periodic coarse training sessions, the system maintains directionality using the previously established parameters, thereby balancing directionality accuracy with reduced training overhead and time consumption.
3Object-affected harmful factors
If directional communications are used to mitigate interference, then interference reduction is improved, but system adaptability to mobile conditions deteriorates
Solution Approach 1:
The patent makes the antenna training system dynamic by implementing a protocol that automatically determines when re-training is needed based on communication conditions. The system transitions between coarse and fine training modes dynamically, performing coarse training periodically to adapt to mobile conditions while maintaining directional communication benefits for interference mitigation during stable periods.
