If reception performance enhancement functionalities are activated, then data transmission quality is improved, but power consumption increases

Engineering Contradiction:

Improvedata transmission qualityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic activation and deactivation of reception performance enhancement functionalities based on real-time determination of physical channel types and data types. The controller adjusts the reception functionality state according to varying communication scenarios, transitioning between enhanced and standard reception modes to optimize the balance between transmission quality and power consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by selecting different reception functionalities based on determined physical channel types (e.g., HSDPA, Rel99/DCH) and data types. This parameter adjustment allows the terminal to adapt reception performance enhancement levels to match actual communication requirements, reducing unnecessary power consumption while maintaining quality when needed.

2Reliability

If reception performance enhancement functionalities are used, then data transmission quality is improved, but device complexity increases

Engineering Contradiction:

Improvedata transmission qualityVSAvoidconfiguration complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The communication terminal performs self-determination of physical channel types and data types without requiring external configuration or manual setup. The determiner automatically identifies communication connection characteristics, and the controller autonomously decides which reception functionalities to activate, eliminating the need for complex user configuration while maintaining optimal performance.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system employs a universal determination mechanism that handles multiple physical channel types and data types through a single integrated approach. The determiner and controller work together to manage various reception enhancement functionalities (receive diversity, equalization, interference cancellation) using a consistent decision-making framework, simplifying the overall system architecture.

Inventive Principle:

Principle #6Universality (Multi-functionality)
