Kind Code:
A1
Abstract:
A cell search method of a terminal in a wireless communication system, comprises: a step of receiving a narrow band synchronization sequence through a narrow band from a base station; and a step of acquiring time synchronization and frequency synchronization with the base station on the basis of the narrow band synchronization sequence and detecting an identifier of the base station, wherein the narrow band has a system bandwidth of 180 kHz and includes twelve carriers arranged at intervals of 15 kHz, and the narrow band synchronization sequence consists of a first narrow band synchronization sequence and a second narrow band synchronization sequence, wherein the first narrow band synchronization sequence can be transmitted in a sixth subframe of a radio frame and the second narrow band synchronization sequence can be transmitted in a tenth subframe of the radio frame.
