Sidelink Synchronization Using Segmented Frequency Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink communication systems struggle with ensuring synchronization among terminals with different communication capabilities, as they assume uniform capabilities, leading to synchronization difficulties.
Innovation Solution
A sidelink synchronization method and apparatus that allows for the transmission and reception of sidelink synchronization signal blocks on specific frequency domain resources, tailored to individual terminal capabilities, using a processor and memory to execute a computer program for synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all terminals are assumed to have identical capabilities and use the same frequency domain resources for S-SSB transmission, then the system configuration is simple and uniform, but synchronization cannot be achieved among terminals with different capabilities
Solution Approach 1:
The frequency domain resources for S-SSB transmission are segmented into multiple RB sets. Terminals with different capabilities can be assigned to different RB sets, allowing synchronization to be achieved for each terminal type while maintaining overall system organization
Solution Approach 2:
Different frequency domain resources (RB sets) are allocated to terminals with different capabilities. This local differentiation in resource quality enables each terminal type to operate at its optimal capability level while achieving synchronization within its assigned resources
2Adaptability or versatility
If multiple RB sets are used for S-SSB transmission to support different terminal capabilities, then synchronization among diverse terminals is achieved, but the complexity of detecting and receiving S-SSBs increases for terminals
Solution Approach 1:
The multiple RB sets are segmented and assigned to different terminal capability groups. Each terminal only needs to detect and receive S-SSBs on its assigned RB set rather than all RB sets, reducing operational complexity while maintaining adaptability to different capabilities
Solution Approach 2:
Each terminal type is assigned specific RB sets matched to its capabilities. This local optimization reduces the detection and reception burden on each terminal to only the relevant RB sets, rather than requiring all terminals to handle all RB sets

AI summary
A sidelink synchronization method is applied to a terminal, and includes that: the terminal sends or receives a sidelink synchronization signal block (S-SSB) on a first frequency domain resource, wherein the first frequency domain resource is all or part of a system frequency domain resource. There is further provided a terminal and a computer readable storage medium, which implements the operations in the sidelink synchronization method.
