AI Technical Summary

Technical Problem

Existing 5G communication systems face challenges in efficiently transmitting synchronization signals between terminals in various coverage scenarios, including in-coverage, partial coverage, and out-of-coverage scenarios, as well as scenarios involving different cells, which are not adequately addressed by legacy LTE D2D or LTE V2X technologies.

Method used

A method for transmitting synchronization signals by a first terminal, involving receiving first synchronization information from a base station, determining second synchronization information based on the subcarrier spacing used for a sidelink, and transmitting this information to a second terminal, supporting NR sidelink and LTE sidelink synchronization across different coverage scenarios and cells.

Benefits of technology

This approach enables efficient transmission of sidelink synchronization signals, facilitating seamless communication between terminals in diverse coverage conditions and supporting advanced services like platooning and remote driving in NR V2X.
