Abstract

The present invention relates to a wireless communication system, and discloses a method and an apparatus for communication between a relay node (RN) and user equipment (UE) in the wireless communication system. The method for enabling the relay node to perform downlink communication with a base station (eNB) and the user equipment, according to one embodiment of the present invention, comprises the steps of: transmitting, to the user equipment, at least an access control channel or a reference signal in the first i number (wherein, i≥1) of symbols of a first slot of an access downlink subframe set from the relay node to the user equipment, wherein said symbols correspond to the first i number of symbols of a first slot of a backhaul downlink subframe set from the base station to the relay node; switching transmitting and receiving operations of the relay node in a predetermined slot in a period from the (i+1)th symbol to the (i+j)th symbol (wherein, j≥1) of the first slot of the backhaul downlink subframe; receiving, from the base station, a backhaul downlink signal in the period from the (i+j+1)th symbol of the first slot of the backhaul downlink subframe to the last symbol of a second slot of the backhaul downlink subframe; and transmitting an access downlink signal to the user equipment via an access downlink subframe which follows the backhaul downlink subframe.
