METHOD FOR SETTING SEARCH SPACE FOR RELAY NODE IN WIRELESS COMMUNCATION SYSTEM AND DEVICE THEREFOR
First Claim
1. A method for receiving a control signal by a relay node from a base station in a wireless communication system, the method comprising:
- receiving a downlink signal from the base station; and
obtaining a control information for the relay node by performing blind decoding on the downlink signal,wherein a search space for performing the blind decoding is located in a data region of a subframe andwherein the search space is partitioned into a search space for a downlink grant and a search space for an uplink grant.

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.
