Abstract:
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.
