1Adaptability or versatility

If the number of component carriers and channel bandwidth are made variable to improve system adaptability, then communication flexibility is improved, but device complexity and computational complexity increase

Engineering Contradiction:

Improveadaptability to variable component carriersVSAvoidsignal processing path complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication signal is divided into multiple divided signals based on the number of component carriers and the number of signal processing paths. Each divided signal is then distributed to corresponding signal processing paths for independent processing, which simplifies the overall system complexity while maintaining adaptability to variable component carriers

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The signal processing system dynamically adapts to variable component carriers by dividing the communication signal into an appropriate number of divided signals that match the available signal processing paths. This dynamic allocation allows the system to handle different numbers of component carriers without requiring complex reconfiguration of the entire processing architecture

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If all cases for changes in component carriers and channel bandwidth are considered to improve system adaptability, then communication flexibility is improved, but computational complexity greatly increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The signal processing paths are designed to handle multiple scenarios universally. By dividing the communication signal into divided signals that can be distributed across available processing paths, the system can handle various component carrier configurations using the same basic processing architecture, avoiding the need for separate processing logic for each possible configuration
