Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If channel aggregation is implemented to improve communication efficiency and throughput, then data transmission performance is improved, but device complexity increases
Solution Approach 1:
The patent segments data transmission by dividing it into multiple independent channels operating in different frequency bands. Each channel can be independently configured and managed, allowing the system to achieve aggregation benefits while maintaining simpler individual channel structures that are easier to implement and manage.
Solution Approach 2:
The patent creates channels that are universally compatible with both legacy devices and channel aggregation-capable devices. Each aggregated channel is designed to function independently as a standard channel, enabling multi-functionality where the same infrastructure serves both simple and advanced communication needs.
2Reliability
If multiple frequency bands are utilized to improve propagation and interference characteristics, then communication reliability is improved, but spectrum resource management complexity increases
Solution Approach 1:
The patent applies local quality by selecting specific frequency bands and channels based on local propagation conditions and interference characteristics. Each aggregated channel is optimized for its specific frequency band's properties, allowing the system to exploit local spectral advantages while maintaining overall communication reliability.

AI summary
Multiple channels are aggregated. In an example embodiment, first data is transmitted on a first channel to a wireless device, and second data is simultaneously transmitted on a second channel to the wireless device. The first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second channel. Various example channel characteristics and combinations thereof are described. Different data allocation options for aggregated channels are described. Other alternative implementations are also presented herein.
