Method for transmitiing or receiving pdcch and user equipment or base station for the method

Provided is a method for a UE to receive a Physical Downlink Control Channel (PDCCH) in a downlink subframe in a wireless communication system according to an embodiment of the present invention. The method includes a step in which a blind decoding process is conducted on search spaces including multiple PDCCH candidates in the downlink subframe to detect PDCCHs while the blind decoding process can be conducted according to the order of the multiple sub search spaces of the search spaces when the blind decoding process is conducted on the search spaces. [Reference numerals] (AA) Subframe index; (BB,FF) E-PDCCH SS1 blind decoding; (CC,HH) PDSCH demodulation; (DD,II) PDSCH turbo decoder; (EE) High rate packet; (GG) E-PDCCH SS2 blind decoding; (JJ) Low rate packet
