METHOD FOR RECEIVING DOWNLINK DATA CHANNELS IN MULTICELL-BASED WIRELESS COMMUNICATION SYSTEMS AND APPARATUS FOR SAME

摘要

A method and a user equipment (UE) for receiving, and a method and a base station (BS) for transmitting a UE specific reference signal based-downlink data channel in a wireless communication system are discussed. The method for receiving a UE specific reference signal based-downlink data channel according to an embodiment includes receiving a downlink control channel from a network; and receiving the UE-specific reference signal based-downlink data channel from the network based on the downlink control channel. The downlink control channel includes an indicator indicating one of two or more parameters configured by a higher layer. The two or more parameters indicate antenna ports of a certain reference signal which is assumed to be quasi co-located with antenna ports of a UE-specific reference signal.
