Abstract:
1. A method for receiving a Physical Downlink Control Channel (PDCCH) in a wireless access system that supports multiple carriers, the method comprising: performing blind decoding in a search space allocated to a user equipment in order to search for the PDCCH; and receiving a PDCCH including Downlink Control Information (DCI), whose size has been adjusted, in the search space, wherein the size of the DCI has been adjusted taking into consideration bandwidth allocated to the user equipment and a transmission mode of a Component Carrier (CC) allocated to the user equipment, wherein the size of the DCI is adjusted based on the transmission mode of the CC allocated to the user equipment, when the difference in payload sizes of the DCI according to the bandwidth is less than a threshold value, and wherein the size of the DCI is adjusted for each bandwidth group formed through bandwidth grouping, when the difference in payload sizes of the DCI according to the bandwidth is greater than the threshold value.
