Method for setting search space for relay node in wireless communcation system and device therefor

Abstract

Disclosed in the present invention is a method for a relay node to receive a control signal from a base station in a wireless communication system. More particularly, the present invention comprises the steps of: receiving a downlink signal from the base station; and obtaining control information for the relay node by blind-decoding the downlink signal, wherein a search space for blind decoding is located in the data region of a subframe, and is divided into a search space for a downlink grant and a search space for an uplink grant. When the subframe corresponding to the control information for the relay node is a downlink (DL) standalone, the search area including only the search space for the downlink grant, or the search area for the uplink grant being set as an invalid search space would be desirable.
