Solution Overview

Problem

Current mobile communication networks lack an intelligent decision-making process to optimize the use of MIMO and SIMO transmission modes, leading to inefficient energy consumption and increased costs, as they primarily rely on cell load without considering additional user information.

Innovation Solution

A method that determines transmission modes based on the evaluation of application and device awareness, using thresholds to select between SIMO and MIMO configurations, taking into account the required throughput and applying weighting factors for more accurate energy management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If MIMO transmission mode is used to achieve high throughput, then user data rate is improved, but energy consumption increases

Engineering Contradiction:
Improveuser throughputVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between MIMO and SIMO transmission modes based on real-time evaluation of application requirements and device capabilities. The transmission mode is not fixed but adapts to changing conditions, enabling the network to optimize the trade-off between throughput and energy consumption by selecting the appropriate mode for each user and application scenario

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the operational parameters of the transmission system by adjusting the transmission mode (MIMO/SIMO) based on evaluated conditions such as application throughput requirements, device antenna capabilities, and channel conditions. This parameter adjustment allows the system to achieve high throughput when needed while conserving energy when standard transmission suffices

Inventive Principle:
Principle #35Parameter changes

2Reliability

If MIMO mode is activated for all users to ensure high performance, then user experience is improved, but operational costs increase

Engineering Contradiction:
Improveuser experienceVSAvoidoperational cost
Core Design Contradiction:
ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The system applies different transmission modes to different users and applications based on their specific requirements. Instead of uniformly applying MIMO to all users, the invention evaluates each user's application needs and device capabilities, applying MIMO only where it provides necessary performance benefits, thereby optimizing the balance between user experience and operational cost

Inventive Principle:
Principle #3Local quality

3Device complexity

If basic cell load-based decisions are used for transmission mode selection, then system complexity is reduced, but optimization capability is insufficient

Engineering Contradiction:
Improvedecision-making complexityVSAvoidoptimization capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system implements a feedback mechanism that collects information about application requirements, device capabilities, and current transmission performance. This feedback is used to continuously evaluate and adjust transmission mode decisions, enabling sophisticated optimization while maintaining manageable system complexity through structured evaluation processes

Inventive Principle:
Principle #23Feedback
