Method for receiving downlink data channels in multicell-based wireless communication systems and apparatus for same

A method for transmitting a user equipment (UE)-specific reference signal based-downlink data channel by a base station (BS) in a wireless communication system, the method comprising:

• transmitting, by the BS, a downlink control channel to a UE;
• and
• transmitting, by the BS, the UE-specific reference signal based-downlink data channel to the UE based on the downlink control channel,
• wherein the downlink control channel includes an indicator indicating one of two or more parameters configured by a higher layer, and
• wherein the two or more parameters indicate certain reference signals which are assumed to be quasi co-located with a UE-specific reference signal.

A user equipment (UE) in a wireless communication system, the UE comprising:

• a radio frequency (RF) module;
• and
• a processor configured to control the RF module to:
• receive a downlink control channel from a network, and
• receive a UE-specific reference signal based-downlink data channel from the network based on the downlink control channel,
• wherein the downlink control channel includes an indicator indicating one of two or more parameters configured by a higher layer, and
• wherein the two or more parameters indicate certain reference signals which are assumed to be quasi co-located with a UE-specific reference signal.
