1. A method for monitoring control channels by a relay node (RN), the method comprising:
- receiving multicast/broadcast single frequency network (MBSFN) configuration from a base station (BS), the MBSFN configuration indicating at least one BS-to-RN subframe among a plurality of subframes, the at least one BS-to-RN subframe being for communication from the BS to the RN, the at least one BS-to-RN subframe being configured as a MBSFN subframe by the RN;
monitoring a downlink (DL) control channel intended for the RN in the at least one BS-to-RN subframe, the DL control channel including a downlink resource assignment; and
when the downlink resource assignment is detected in a specific frequency band of the DL control channel of the at least one BS-to-RN subframe, and when the downlink resource assignment indicates the specific frequency band, receiving downlink data on a DL data channel of the at least one BS-to-RN subframe indicated by the downlink resource assignment,wherein the DL data channel is received in the specific frequency band of the at least one BS-to-RN subframe.

Abstract
A method of transmitting a signal of a base station in a wireless communication system is provided. The method includes transmitting a first signal to the relay station through the transmission period in a subframe including a transmission period and a guard time for transmission/reception switching of a relay station, and transmitting a second signal to a macro user equipment through the guard time. Accordingly, a signal can be effectively transmitted in the wireless communication system employing the relay station.
