Sidelink Synchronization Resource Split for Reduced-Capability Terminals

Solution Overview

Problem

Current sidelink synchronization schemes are not applicable to reduced-capability terminals, leading to high power consumption and increased complexity due to the assumption of equal capabilities among all terminals, which is not feasible in commercial deployment scenarios.

Innovation Solution

The synchronization resources for sidelink communication are divided into two types, one for high-capability terminals and another for low-capability terminals, with separate configuration information ensuring efficient synchronization while reducing power consumption and complexity.

1Reliability

If current sidelink synchronization schemes are applied to reduced-capability terminals, then synchronization can be achieved, but power consumption and terminal complexity increase significantly

Engineering Contradiction:

Improvesynchronization capabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent segments synchronization resources into two distinct types: first-type S-SSB synchronization resources for high-capability terminals and second-type S-SSB synchronization resources for reduced-capability terminals. This segmentation allows each terminal type to use optimized resources suited to its capabilities, reducing power consumption for reduced-capability terminals while maintaining synchronization reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by providing different configuration information for different terminal types. First configuration information is provided for first-type terminals with higher capabilities, while second configuration information is provided for second-type terminals with reduced capabilities. This ensures each terminal type uses resources optimized for its specific capabilities, reducing unnecessary power consumption.
