    摘要： The present invention relates to a wireless communication system, and provides a method and an apparatus for transmitting a downlink reference signal in the wireless communication system. The method for enabling a base station to transmit the reference signal to a terminal using layers of 8 or less in accordance with one embodiment of the present invention comprises the steps of: transmitting data for the layers of 8 or less through a data domain of a downlink sub frame; and transmitting a reference signal for the layers of 8 or less on a fixed OFDM symbol of the downlink sub frame, wherein the reference signal is a DRS (Dedicated Reference Signal) which demodulates the data for the layers of 8 or less, and the reference signal for the layers of 8 or less is separated into 1st and 2nd groups, and reference signals of the 1st and 2nd groups can be multiplexed in a CDM (Code Division Multiplexing) method on one resource element, respectively.

    摘要： A method of transmitting and receiving feedback information in a multi-cell based wireless communication system using FFR, a mobile station apparatus therefore and a base station apparatus therefore are disclosed. A mobile station is able to obtain FFR configuration information including configuration information on at least one frequency partition to which a corresponding FFR is applied per cell ID. And, the mobile station is able to transmit PMI information to a serving base station using the obtained FFR configuration information. In this case, the PMI information is specifically restricted or recommended by the mobile station among PMIs (precoding matrix indexes) used by at least one neighbor cell in an allocated specific frequency partition.
