    摘要: The present invention relates to a method for transceiving scheduling signals in a multi-carrier wireless communication system, comprising a step of transmitting, via a predetermined downlink component carrier, a PDSCH transmission scheduling signal on one or more downlink component carriers and/or a PUSCH transmission scheduling signal on one or more uplink component carriers; and a step of transceiving the PDSCH and/or the PUSCH in accordance with the scheduling signals. The scheduling signals can be defined to the same size in a PDCCH transmission region of said predetermined downlink component carrier in the event different MIMO transmission modes are applied to the PDSCH transmission or the PUSCH transmission, or in the event said one or more downlink component carriers or said one or more uplink component carriers have different bandwidths.
