Solution Overview

Problem

Current wireless communication devices face challenges in optimizing antenna performance across varying usage modes and environments, leading to suboptimal signal selectivity and directivity.

Innovation Solution

A radiation pattern recognition scheme is implemented in wireless UE devices, which identifies the current usage mode through multivariate situational data and matches it with benchmark radiation patterns to optimize antenna performance, enhancing signal selectivity and directivity by adjusting antenna settings, modulation, and power levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antenna settings are optimized for one usage mode, then signal selectivity and directivity are improved for that mode, but performance deteriorates in other usage modes

Engineering Contradiction:
Improvesignal selectivity and directivityVSAvoidperformance across varying usage modes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic antenna configuration by continuously monitoring usage mode through multivariate situational data and adjusting antenna settings in real-time. The system transitions from static, mode-specific optimization to dynamic adaptation, where antenna parameters are automatically adjusted based on current usage conditions, resolving the contradiction between optimized performance in one mode and adaptability across multiple modes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes antenna operational parameters (such as radiation patterns, power levels, and configuration settings) based on detected usage modes. By matching current usage mode with benchmark radiation patterns and adjusting parameters accordingly, the system achieves optimal signal selectivity and directivity for each specific usage scenario while maintaining versatility across different modes.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If antenna performance is optimized through complex radiation pattern recognition, then signal quality improves, but device complexity increases

Engineering Contradiction:
Improvesignal qualityVSAvoidcomplexity of radiation pattern recognition system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent pre-establishes benchmark radiation patterns for multiple usage modes before actual operation. During runtime, the system only needs to match current situational data against these pre-computed benchmarks and select the best match, rather than performing complex real-time radiation pattern calculations. This preliminary preparation significantly reduces computational complexity while maintaining high signal quality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses pre-measured benchmark radiation patterns as reference copies for different usage modes. Instead of calculating unique radiation patterns for each situation, the system creates matches between current conditions and stored benchmark patterns, simplifying the complexity by using replicated reference data rather than performing complex real-time computations.

Inventive Principle:
Principle #26Copying
