Solution Overview

Problem

Terminals in idle or inactive states frequently need to retune their radio frequency to perform operations like measurement and synchronization on initial BWPs, leading to increased power consumption and service interruptions.

Innovation Solution

Configuring NCD-SSB or CD-SSB for terminals in idle or inactive states to allow reuse of these signals, reducing the need for frequent retuning and minimizing power consumption and service delays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If terminals frequently retune radio frequency to initial BWP for measurement and synchronization operations, then measurement and synchronization accuracy are improved, but power consumption increases and service interruptions occur

Engineering Contradiction:

Improvemeasurement and synchronization accuracyVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The network side device pre-configures measurement and synchronization reference signals (NCD-SSB or CD-SSB) on the separate initial BWP before the terminal needs to perform measurements. This preliminary configuration allows terminals to perform measurement and synchronization operations without frequent retuning to the initial BWP, thereby reducing power consumption while maintaining measurement accuracy.

Principle #10Preliminary action

2Measurement precision

If terminals frequently retune radio frequency to initial BWP for operations, then synchronization accuracy is improved, but service delays increase

Engineering Contradiction:

Improvesynchronization accuracyVSAvoidservice delay

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The network side device pre-configures synchronization reference signals (NCD-SSB or CD-SSB) on the separate initial BWP, enabling terminals to perform synchronization operations without interrupting service to retune to the initial BWP. This eliminates service delays caused by frequent retuning while maintaining synchronization accuracy.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If terminals use configured grant resource uplink small data transmission or random access-small data transmission on separate initial BWP, then uplink transmission capability is improved, but frequent retuning to initial BWP increases power consumption

Engineering Contradiction:

Improveuplink transmission capabilityVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The network side device pre-configures measurement and synchronization reference signals on the separate initial BWP where uplink small data transmission resources are allocated. This allows terminals to perform uplink transmission operations without needing to retune to the initial BWP for measurement and synchronization, thereby maintaining uplink transmission capability while reducing power consumption from frequent retuning.
