Abstract: A method is provided for receiving a downlink signal through an Enhanced Physical Downlink Control Channel (EPDCCH) in a wireless communication system by a user equipment (UE). The UE receives a parameter indicating a quasi co-location behavior type is. The UE further receives a demodulation reference signal (DMRS) associated with the EPDCCH. The UE attempts to decode the EPDCCH based on the DMRS. If a transmission mode configured in the UE is a transmission mode 10, the UE assumes that antenna ports of the DMRS are quasi co-located with antenna ports of a reference signal determined by the parameter.
