Patent ID: 8908628

Claim:
A method for receiving a downlink signal in a wireless communication system, the method comprising: receiving a subframe including two slots; performing blind decoding (BD) of a plurality of Relay Physical Downlink Control Channel (R-PDCCH) candidates so as to receive control information in a search space of a first slot; and if the R-PDCCH is detected in the search space, determining whether the R-PDCCH carries either control information for downlink transmission or control information for uplink transmission based on which Radio Network Temporary Identifier (RNTI) is masked to a Cyclic Redundancy Check (CRC) of the R-PDCCH, wherein a RNTI allocated for the control information for downlink transmission is different from a RNTI allocated for the control information for uplink transmission, and wherein the control information for downlink transmission is the same size as the control information for uplink transmission.
