1. A method of operating multi-band and multi-cell, the method comprising:

  • transmitting a synchronization channel and a broadcasting channel for narrow-band User Equipments (UEs) through a first band narrower than a system band, the first band being located in a center band of the system band;

    transmitting a control channel for scheduling a data channel for a first narrow-band UE, which is one of the narrow-band UEs, through a second band equal to or wider than the first band, the second band not overlapping the first band within the system band; and

    establishing Radio Resource Control (RRC) connection with the first narrow-band UE which is one of the narrow-band UEs through the first band, and transmitting information on the second band and location information of a subframe where the control channel is transmitted to the first narrow-band UE through the RRC connection,wherein the first band is equal to a band where the synchronization channel and the broadcasting channel of a host cell using an entire system band are transmitted.
