Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If carrier aggregation technology is implemented to achieve high-speed data transmission, then communication speed is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the baseband processing into multiple independent branches, where each branch processes a specific component carrier. This modular segmentation allows the mobile station to handle multiple CCs through parallel independent processing units, reducing the complexity of unified processing while maintaining high-speed transmission capability
Solution Approach 2:
The patent enables dynamic configuration of baseband processing branches based on the number and characteristics of aggregated component carriers. The mobile station can adaptively activate or deactivate processing branches according to carrier aggregation status, optimizing resource allocation and reducing unnecessary power consumption when fewer CCs are aggregated
2Speed
If multiple component carriers are aggregated for high-speed communication, then communication performance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic power management by enabling the mobile station to selectively activate baseband processing branches based on the actual number of aggregated component carriers. When fewer CCs are aggregated, fewer processing branches are activated, directly reducing power consumption while maintaining optimal communication performance
Solution Approach 2:
The patent changes the operational parameters of the baseband processing system by adjusting the number of active processing branches according to carrier aggregation configuration. This parameter adaptation allows the system to optimize the balance between communication speed and power consumption based on real-time network conditions
3Adaptability or versatility
If comprehensive LTE-A technical elements are supported for maximum compatibility, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal baseband processing architecture where each processing branch can handle multiple LTE-A technical elements including different transmission modes, MIMO configurations, and carrier aggregation scenarios. This multi-functional design allows comprehensive LTE-A support through standardized processing units rather than dedicated hardware for each feature
Solution Approach 2:
The patent segments the baseband processing into independent branches that can be selectively configured to support different LTE-A technical elements. This segmentation allows the mobile station to enable only the necessary processing capabilities required for current network conditions, reducing complexity while maintaining adaptability to various LTE-A features

AI summary
An ASN encoder of a carrier aggregation capable mobile station apparatus generates transmission and reception capability information including information relating to one or a plurality of component carriers to be used for communication with a base station apparatus. A transmission and reception apparatus transmits the transmission and reception capability information to the base station apparatus. A controller controls the communication with the base station apparatus, using the one or the plurality of component carriers assigned by the base station apparatus based on the transmission and reception capability information.
