Solution Overview

Problem

Wireless communications systems face challenges in managing power consumption and performance trade-offs due to varying channel conditions, with existing UE receiver configuration methods either increasing power consumption or reducing throughput and spectral efficiency.

Innovation Solution

A network node dynamically selects receiver types for different portions of a downlink communication based on channel conditions, using more power-efficient algorithms for better resources and more complex algorithms for poorer resources, reducing UE power consumption without significantly affecting performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If more complex receiver algorithms are used for all downlink portions, then throughput and spectral efficiency are improved, but power consumption increases

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

Solution Approach 1:

The patent applies local quality by selecting different receiver algorithms for different portions of downlink communication based on channel conditions. Complex algorithms are applied only to portions with poor channel conditions where they are needed, while simpler algorithms are used for portions with good channel conditions, thereby reducing overall power consumption while maintaining throughput.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by dynamically selecting receiver algorithms based on real-time channel conditions. The network node determines channel conditions and adaptively chooses appropriate receiver types for different downlink portions, allowing the system to transition between complex and simple algorithms as conditions change, optimizing both power consumption and throughput.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If simpler receiver algorithms are used for all downlink portions, then power consumption is reduced, but throughput and spectral efficiency decrease

Engineering Contradiction:
Improvepower consumptionVSAvoidthroughput
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The patent applies local quality by matching receiver algorithm complexity to local channel conditions. Simple algorithms are used for portions with good channel conditions where they suffice, while complex algorithms are reserved for portions with poor conditions, ensuring throughput is maintained only where necessary while minimizing overall power consumption.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by enabling flexible switching between simple and complex receiver algorithms based on channel conditions. This dynamic adaptation allows the system to use simpler algorithms when conditions permit, reducing power consumption, while automatically deploying complex algorithms when channel conditions deteriorate, preventing throughput loss.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If receiver configuration is optimized for power efficiency, then device complexity is reduced, but network performance is affected

Engineering Contradiction:
Improvereceiver complexityVSAvoidnetwork performance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies local quality by configuring receiver complexity according to local channel conditions. The network node determines which portions of downlink communication require complex processing and configures the UE accordingly, rather than uniformly configuring the entire receiver. This reduces overall device complexity while maintaining network performance by applying complex processing only where necessary.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by making receiver configuration adaptive to changing channel conditions. The network node can dynamically reconfigure receiver parameters based on current channel quality, allowing the system to reduce complexity when conditions are good while maintaining performance when conditions are poor, thus balancing complexity and reliability dynamically.

Inventive Principle:
Principle #15Dynamics
