Abstract

A method of performing a downlink machine type communication from a base station to a MTC (machine type communication) terminal includes, at the base station, transmitting at least one of a system information—the system information excluding a Master Information Block (MIB)—, a control information and data to the MTC terminal using a system bandwidth having a predetermined size. The base station performs frequency hopping using a frequency hopping pattern in a unit of narrow band on the at least one of the system information—the system information excluding a Master Information Block (MIB)—, the control information and the data to transmit to the MTC terminal, and the narrow band is less than the system bandwidth.
