METHOD AND APPARATUS FOR A SYNCHRONIZATION IN A MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to improved synchronization method and apparatus in a mobile communication system. According to an embodiment of the present invention, provided is a synchronization signal transmission method for a base station in a filter bank multi-carrier (FBMC) system, the synchronization signal transmission method comprising the steps of: generating a frequency-domain quadrature amplitude modulation (QAM) symbol sequence having a length of K for a synchronization signal; mapping the QAM symbol sequence to a subcarrier of a filter bank based on correlation characteristics of the synchronization signal; generating a quadrature amplitude modulation-filter bank multi-carrier (QAM-FBMC) symbol including the synchronization signal based on the mapping; and transmitting the generated QAM-FBMC symbol. Also provided may be a base station using the synchronization method. Furthermore, provided are a terminal communicating with the base station, and a method for operating the terminal.
