Solution Overview

Problem

Existing communication systems face challenges in managing network capacity limitations and optimizing antenna performance in high-frequency bands, particularly in environments where reception quality fluctuates due to user interaction or environmental factors.

Innovation Solution

An electronic device equipped with multiple antennas and processors that dynamically switch transmission antennas based on conditions such as signal-to-noise ratio (SNR) and reference signal received power (RSRP) delta values, using impedance tuning codes to optimize reception and transmission performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single antenna is used for transmission in high-frequency bands, then device complexity is reduced, but reception quality becomes unstable due to environmental factors and user interaction

Engineering Contradiction:
Improvereception qualityVSAvoidantenna management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic antenna switching between first and second antennas based on real-time reception quality measurements. The system transitions from a static single-antenna configuration to a dynamic multi-antenna system that adapts to environmental changes, user interaction, and signal conditions to maintain stable reception quality in high-frequency bands.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operating parameter by switching between different antennas (first antenna and second antenna) based on measured reception quality. This parameter change allows the system to optimize transmission performance by selecting the antenna with better reception characteristics under varying environmental conditions.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If multiple antennas are deployed to improve reception quality, then reliability increases, but device complexity and antenna switching management become more difficult

Engineering Contradiction:
Improvereception quality stabilityVSAvoidantenna switching management
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs self-service by automatically measuring reception quality on each antenna and autonomously determining which antenna to switch to, without requiring external intervention or complex manual management. The electronic device itself monitors and manages the antenna switching based on real-time performance metrics.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback by continuously measuring reception quality on the current antenna and using this information to determine whether to switch to another antenna. This closed-loop feedback mechanism simplifies management by automatically adjusting antenna selection based on measured performance rather than requiring complex external control.

Inventive Principle:
Principle #23Feedback

3Reliability

If antenna switching is performed frequently to maintain optimal reception quality, then communication reliability improves, but loss of time due to switching operations increases

Engineering Contradiction:
Improvecommunication stabilityVSAvoidantenna switching time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial action by switching antennas only when necessary, based on whether reception quality meets a predetermined threshold or shows significant degradation. Rather than continuously switching or switching at fixed intervals, the system performs switching only when the measured reception quality indicates a need for change, reducing unnecessary switching operations.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system measures reception quality in advance before making switching decisions, allowing it to anticipate when a switch may be needed. By continuously monitoring reception quality metrics beforehand, the system can make informed switching decisions that minimize disruption and reduce the time lost during actual switching operations.

Inventive Principle:
Principle #10Preliminary action

AI summary

An electronic device is provided. The electronic device includes a first antenna, a second antenna, memory storing one or more computer programs, and one or more processors communicatively coupled to the first antenna, the second antenna, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors, cause the electronic device to determine whether the first antenna operates with transmission (TX) code in antenna impedance tuning (AIT) code, determine whether a first condition for reception quality of the first antenna and the second antenna is satisfied when the first antenna operates with the TX code, determine whether a second condition for the reception quality of the first antenna and the second antenna is satisfied when the first antenna operates with other code that is different from the TX code in the AIT code, and control the second antenna to operate as a main transmission antenna when both the first condition and the second condition are satisfied.
