Solution Overview

Problem

Current wireless communication systems face challenges in efficiently controlling transmission power, leading to interference and high power consumption in mobile terminals, which affects transmission quality and battery life, and requires more tailored power control mechanisms, especially for sensitive services like ultra-reliable low-latency communications (URLLC).

Innovation Solution

A method using a neural network to determine optimal uplink power control parameters based on radio access network parameters, traffic types, and conditions, allowing for dynamic adjustment of power control settings to maximize network performance and minimize interference and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If transmission power is increased to improve transmission quality, then transmission quality is improved, but power consumption increases and interference to other transmissions increases

Engineering Contradiction:
Improvetransmission qualityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic power control where the network element continuously monitors transmission conditions, channel quality, and service requirements to adjust power control parameters in real-time. This allows the system to use higher power only when necessary for maintaining transmission quality, rather than maintaining constantly high power levels, thus resolving the contradiction between transmission quality and power consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes power control parameters (such as power offset, pathloss compensation factor) based on detected transmission conditions and service types. By dynamically adjusting these parameters, the system optimizes the balance between transmission quality and power consumption, ensuring adequate quality only when required while minimizing overall power usage.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If transmission power is increased to improve transmission quality, then transmission quality is improved, but interference to other transmissions increases

Engineering Contradiction:
Improvetransmission qualityVSAvoidinterference
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies different power control strategies and parameter settings for different services and user equipment. By tailoring power control to local conditions and service requirements (such as prioritizing URLLC services), the system maintains transmission quality for critical services while minimizing interference generated by unnecessary high power transmissions in other contexts.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts power levels based on real-time channel conditions, service requirements, and network load. This allows transmission quality to be maintained when necessary while reducing power and interference when conditions permit, resolving the contradiction between quality and interference.

Inventive Principle:
Principle #15Dynamics

3Reliability

If power control parameters are optimized for specific services like URLLC, then service reliability is improved, but system complexity increases

Engineering Contradiction:
Improveservice reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements service-specific power control parameter optimization where different parameter sets are configured for different service types (e.g., URLLC, eMBB, mMTC). The network element detects the service type and applies appropriate parameters, improving service reliability without requiring complete redesign of the power control system for each service.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent segments the power control system into service-specific configurations while maintaining a unified control framework. This allows optimized parameters for critical services like URLLC to be implemented separately from general power control mechanisms, improving service reliability while managing system complexity through modular organization.

Inventive Principle:
Principle #1Segmentation
