Method for setting search space for handover of relay node in wireless communication system, and device therefor

摘要

Disclosed in the present invention is a method for a relay to execute a random access procedure in a wireless communication system. More particularly, the present invention comprises the steps of: transmitting a random access preamble to a target cell; receiving a downlink signal from the target cell; obtaining a relay node-physical downlink control channel (R-PDCCH) by blind decoding the downlink signal; and receiving a random access response message on the basis of the R-PDCCH, wherein a search space for the blind decoding is located in a data region of a subframe, and information on the search space is delivered from the target cell to a serving cell of the relay node, and then signaled to the relay node.

1. A method for performing a random access procedure for handover to a target cell at a relay node in a wireless communication system, the method comprising:
transmitting a random access preamble to a target cell; receiving a downlink signal from the target cell; performing blind decoding with respect to the downlink signal and acquiring a relay node-physical downlink control channel (R-PDCCH); and receiving a random access response message based on the R-PDCCH, wherein search space for performing blind decoding is located in a data region of a subframe, wherein the search space is determined based on information on the search space, and wherein the information on the search space is sent from the target cell to a serving cell of the relay node and is signaled from the serving cell to the relay node.
