Solution Overview

Problem

Current wireless communication systems face challenges in smoothly transitioning between different power states during beamforming operations, leading to transient effects and nonlinearities due to rapid changes in power draw, which can affect signal accuracy and efficiency.

Innovation Solution

The implementation of a method and apparatus that identify a first and second power state associated with beam transmissions or receptions, using a scheduled gap or intermediate power state to smooth the transition between these states, thereby reducing transient effects and nonlinearities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If rapid power state transitions are implemented during beamforming operations, then beamforming responsiveness and adaptability are improved, but transient effects and nonlinearities increase

Engineering Contradiction:

Improvebeamforming responsivenessVSAvoidsignal accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary actions by scheduling gaps before actual power state transitions occur. These gaps allow the beamforming apparatus to prepare for upcoming transitions, reducing the impact of transient effects by anticipating and managing power changes in advance rather than reacting to them abruptly.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Intermediate power states are introduced as intermediary steps between extreme power states. Rather than transitioning directly from high to low power (or vice versa), the system passes through intermediate states that smooth the transition curve, reducing nonlinearities and transient effects while maintaining beamforming adaptability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If direct transition between power states is performed, then transition speed is improved, but transient effects and nonlinearities increase

Engineering Contradiction:

Improvetransition speedVSAvoidtransient effects

Core Design Contradiction:

SpeedVSObject-generated harmful factors

Solution Approach 1:

The transition process is segmented into multiple discrete steps rather than occurring as a single abrupt change. By dividing the transition from one power state to another into intermediate steps, the system maintains faster overall response while reducing the magnitude of transient effects at each individual transition step.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts the transition path by selecting appropriate intermediate power states based on current operating conditions. This dynamic approach allows the system to optimize transition speed while managing transient effects in real-time, adapting the transition strategy to current beamforming requirements.

Inventive Principle:

Principle #15Dynamics

3Reliability

If intermediate power states are used to smooth transitions, then transient effects are reduced, but transition time increases

Engineering Contradiction:

Improvesignal stabilityVSAvoidtransition time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial action by using only the necessary intermediate power states required to achieve smooth transitions, rather than progressing through all possible power levels. This selective approach maintains signal stability while minimizing unnecessary transition time, applying just enough intermediate steps to reduce transient effects without excessive delay.

Inventive Principle:

Principle #16Partial or excessive action
