Claim:
1. A method for acquiring control information via an Enhanced Physical Downlink Control Channel (EPDCCH) at a User Equipment (UE) in a wireless communication system, the method comprising: determining an index of a start Orthogonal Frequency Division Multiplexing (OFDM) symbol of an EPDCCH in a subframe; and attempting to perform decoding on a UE-specific search space of the EPDCCH, wherein if the subframe is a subframe 1 or a subframe 6 for Time Division Duplexing (TDD), the index of the starting OFDM symbol is a smaller value between 2 and a higher-layer parameter which indicates the index of the starting OFDM symbol of the EPDCCH.
