Reference Signals Design and Evaluation on Radio-Interface Based Synchronization of LTE Base Station System

Abstract:

This paper discusses the reference signals used in synchronization for LTE system. In general, primary synchronization signal (PSS) correlation based acquisition and reference signals based tracking loop are applied for time and frequency synchronization but it is unclear which legacy reference signals (RS) will be used as the listening RS for radio-interface based synchronization. Besides the legacy cell-specific reference signals (CRS) utilized as the listening RS, the other potential candidate could be either CSI reference signals (CSI-RS) or position reference signals (PRS). Upon performance evaluation, we compare the pros and cons of CRS, CSI-RS and PRS based synchronization and present our views.
