Solution Overview

Problem

Existing wireless communication protocols face inefficiencies due to the additional resource consumption required for switching between power saving and active modes, leading to system inefficiencies.

Innovation Solution

A wireless device switches between power saving and active states based on received power saving configurations and wake-up indications from a second communication device, optimizing resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a device switches between power saving mode and active mode for different types of services, then power consumption is optimized, but additional resources (frequency resources, time resources, energy resources) are consumed during mode switching

Engineering Contradiction:

Improvepower consumptionVSAvoidresource consumption during mode switching

Core Design Contradiction:

Use of energy by moving objectVSLoss of energy

Solution Approach 1:

The system pre-configures multiple power saving configurations with different parameters (e.g., different monitoring occasions, different bandwidths) before mode switching is needed. When a mode switch is required, the device can immediately activate a pre-configured power saving configuration without performing resource-intensive reconfiguration procedures, thus reducing the resource consumption associated with mode switching.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically selects among multiple pre-configured power saving configurations based on current traffic conditions and service requirements. By having multiple configurations available and selecting the appropriate one dynamically, the system optimizes the balance between power saving effectiveness and resource consumption during mode transitions.

Inventive Principle:

Principle #15Dynamics

2Speed

If a device monitors power saving channels frequently to detect wake-up indications, then response time to data traffic is reduced, but power consumption increases

Engineering Contradiction:

Improveresponse time to data trafficVSAvoidpower consumption during monitoring

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The monitoring of power saving channels is segmented into different levels or phases. The device can use different monitoring strategies depending on the configured power saving mode - for example, monitoring at reduced frequency during deep power saving states while maintaining faster response capability in lighter power saving states. This segmentation allows the device to balance monitoring frequency with power consumption based on current needs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes monitoring parameters (such as monitoring frequency, bandwidth, and timing) based on the active power saving configuration. Different power saving configurations have different associated monitoring parameters, allowing the device to adjust its monitoring behavior to match the desired power saving level while maintaining adequate response capability.

Inventive Principle:
