Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple component carriers and MIMO streams are supported to achieve high-speed data transfer, then data transfer rate is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic allocation of component carriers and MIMO streams based on real-time channel conditions and mobile station capabilities. The base station adjusts the number of active CCs and MIMO configurations adaptively, allowing the system to achieve high data transfer rates when conditions permit while reducing complexity when resources are constrained or channels are poor.
Solution Approach 2:
The system changes operational parameters such as the number of component carriers, bandwidth allocation, and MIMO stream count based on channel quality indicators and mobile station capability reports. By dynamically adjusting these parameters, the system optimizes the trade-off between data transfer rate and device complexity, achieving high speed only when necessary and appropriate.
2Adaptability or versatility
If wireless resources are allocated without considering mobile station capabilities, then allocation flexibility is improved, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements preliminary capability assessment where mobile stations report their supported features (number of component carriers, MIMO capabilities, bandwidth support) before resource allocation begins. The base station uses this pre-collected capability information to make informed allocation decisions, ensuring both flexibility in accommodating different device types and efficiency in matching resources to actual capabilities.
Solution Approach 2:
The system establishes a feedback mechanism where mobile stations provide capability information and channel quality reports to the base station. The base station uses this feedback to continuously optimize resource allocation, adjusting the number of component carriers and MIMO streams based on reported capabilities and actual channel conditions, thereby achieving both flexibility and efficiency.
3Use of energy by moving object
If circuit complexity is reduced to lower power consumption and cost, then power consumption is improved, but compatibility with various LTE-A technical elements deteriorates
Solution Approach 1:
The patent segments the carrier aggregation functionality into modular components that can be independently activated. The mobile station and base station agree on a specific number of component carriers to use based on capability reports and network conditions. This segmentation allows the system to implement only the necessary level of complexity required for each deployment scenario, reducing power consumption and cost while maintaining compatibility with LTE-A features through selective activation.
