Solution Overview

Problem

Electronic devices face increased power consumption and reduced service quality due to continuous identification of channel state information from external devices, especially in latency-sensitive services.

Innovation Solution

A first electronic device transmits a message to a second electronic device requesting it to determine if channel state information from a third device satisfies a condition, allowing the first device to reduce power consumption by avoiding continuous CSI identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the electronic device continuously identifies channel state information based on signals from external devices, then location information accuracy is improved, but power consumption increases

Engineering Contradiction:
Improvelocation information accuracyVSAvoidpower consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The external electronic device performs self-service by autonomously identifying channel state information and determining whether it satisfies predetermined conditions without requiring the first electronic device to continuously perform these operations, thereby reducing the first device's power consumption while maintaining location information accuracy

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The external electronic device acts as an intermediary that performs CSI identification and condition determination tasks on behalf of the first electronic device, receiving signals from third devices, analyzing channel state information, and providing results to the first device, thus reducing the first device's computational burden and power consumption

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If the number of times channel state information is identified increases for latency-sensitive services, then service response speed is improved, but power consumption further increases

Engineering Contradiction:
Improveservice response speedVSAvoidpower consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

Instead of continuous CSI identification, the system employs periodic action where the external electronic device identifies channel state information at specific intervals or triggered events, maintaining service response speed for latency-sensitive applications while avoiding unnecessary continuous measurements that would increase power consumption

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The external electronic device autonomously determines when CSI identification is necessary based on service requirements and predetermined conditions, performing measurements only when needed rather than continuously, thus optimizing the balance between response speed and power consumption

Inventive Principle:
Principle #25Self-service
