Claim:
1. A method for transmitting an enhanced physical downlink control channel (EPDCCH) to a user equipment (UE) at a base station (BS) in a wireless communication system, the method comprising; determining a number of enhanced control channel elements (ECCEs) that form the EPDCCH, based on whether a downlink bandwidth is equal to or larger than a first threshold value or whether a number of available resources for the EPDCCH is smaller than a second threshold value; and transmitting the EPDCCH to the UE, wherein, if the downlink bandwidth is equal to or larger than the first threshold value or if the number of available resources for the EPDCCH is smaller than the second threshold value, the number of the ECCEs is determined to be a value larger than 1, otherwise, the number of the ECCEs is determined to be 1.
