Abstract: A method of transmitting uplink control information (UCI) in a wireless access system supporting carrier aggregation. A user equipment (UE) receives two or more physical downlink shared channels (PDSCHs) via two or more downlink component carriers, respectively. The UE performs channel coding with respect to the UCI according to a payload size of the UCI including acknowledgement information and channel quality information (CQI) for each of the two or more downlink carriers. The UE performs rate matching with respect to the channel coded UCI for a physical uplink control channel (PUCCH) format 3. The UE transmits the rate matched UCI using the PUCCH format 3.

The UE monitors a plurality of Physical Downlink Control Channel (PDCCH) candidates having a cyclic redundancy check (CRC) scrambled by a cell radio network temporary identifier (C-RNTI) and having a same payload size in a common search space and a UE-specific search space on a primary cell to receive the DCI from the BS. The common search space and the UE-specific search space are overlapped. If the UE is configured with a carrier indicator field (CIF), determining, by the UE, that only a PDCCH in the common search space is transmitted by the BS from among the plurality of PDCCH candidates. The UE receives a Physical Downlink Shared Channel (PDSCH) corresponding to the PDCCH in the common search space.
