Solution Overview

Problem

Current scheduling methods by network side devices fail to adapt to different service requirements and terminal states, leading to high power consumption during communication due to inadequate capability information reporting from terminals.

Innovation Solution

A method and system where terminals report assistance information, including capability information, combination indication, power saving indication, and transmit power profile information, to network side devices, enabling flexible and timely adaptation to service requirements and terminal states, thereby reducing power consumption and improving communication performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the terminal reports detailed capability information to the network side device, then the scheduling accuracy and service requirement matching improve, but the power consumption and signaling overhead increase

Engineering Contradiction:

Improvescheduling adaptabilityVSAvoidterminal power consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The capability information is segmented into multiple types including power saving capability information, throughput capability information, and latency capability information. The terminal selectively reports only the relevant segments based on current service requirements and terminal state, avoiding transmission of unnecessary information and reducing power consumption while maintaining scheduling adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The terminal dynamically adjusts the type and amount of capability information reported based on changing service requirements and terminal states. The network side device receives updated capability information when the terminal state changes, enabling adaptive scheduling without continuous reporting of all capability parameters, thus balancing adaptability with power efficiency.

Inventive Principle:

Principle #15Dynamics

2Reliability

If the terminal continuously updates capability information to reflect different terminal states, then the scheduling accuracy improves, but the signaling overhead and power consumption increase

Engineering Contradiction:

Improvescheduling accuracyVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts and reports only the specific capability information that is relevant to current service requirements and terminal states. Instead of transmitting complete capability sets continuously, the terminal extracts and reports only the necessary subsets (power saving, throughput, or latency capabilities) based on current needs, reducing signaling overhead while maintaining scheduling accuracy.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The network side device uses the reported capability information to provide feedback in the form of downlink control information that reflects the terminal's current state and service requirements. This feedback mechanism enables accurate scheduling without requiring continuous uplink reporting of all capability parameters, reducing signaling overhead while maintaining reliability.

Inventive Principle:

Principle #23Feedback
