Abstract: A method is provided for receiving a user equipment (UE) specific reference signal based-downlink data channel by a UE in a wireless communication system. The UE receives, from a network, a downlink control channel including either first scheduling information or second scheduling information, and receives the UE-specific reference signal based-downlink data channel from the network based on the downlink control channel. When the downlink control channel includes the first scheduling information, antenna ports of a certain reference signal which can be assumed to be quasi co-located with antenna ports of a UE-specific reference signal is configured by an indicator indicating one of two or more parameters configured by a higher layer. When the downlink control channel includes the second scheduling information, the antenna ports of a certain reference signal is configured by a parameter of a minimum index among the two or more parameters.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for reporting a channel state by a terminal to a serving base station in a wireless communication system, wherein extra channel state information is reported to enable the serving base station to estimate the channel state more accurately. When the base station estimates the channel state with the terminal, the channel state information received from the terminal, the extra channel state information, and traffic information of neighboring base stations are collectively considered to estimate the channel state with the terminal, thereby enabling estimation of the channel state with improved reliability and accuracy.
