Link-Level Performance Evaluation of Sidelink Synchronization Signal Block for 5G V2X

Abstract

In this paper, we evaluate the performance of sidelink synchronization signal block (SL-SSB) for 5G vehicular-to-everything (V2X) communication systems. The SLSSB serves to establish communication link by synchronizing signals between the vehicles. We first introduce the transmission structure of SL-SSB and related synchronization procedures based on the standard documents presented by 3rd Generation Partnership Project (3GPP). Then, we develop a link level simulator (LLS), and evaluate the SL identity (ID) detection performance based on the SL-SSB and block error rate (BLER) performance for the physical sidelink broadcast channel (PSBCH).
