    摘要： The present invention relates to a wireless communication system having at least one base station utilizing CoMP (Coordinated Multi-Point) transmission, wherein a terminal receives a reference signal from said at least one base station. If said at least one base station makes a transmission based on said reference signal through Coordinated beamforming (CB), information based on PMI (Precoding Matrix Index) corresponding to each base station is determined. Accordingly, if said at least one base station makes a transmission based on joint processing, phase set information is determined for phase correction of the formed beam. Thus, the present method transmits feedback information, comprising PMI set information based on CB and said phase set information, from said at least one base station to a server base station.

    摘要： The present invention relates to a method for transmitting a pilot signal in a downlink MIMO (Multi Input Multi Output) system that supports a first UE (User Equipment) supporting N number of transmission antennae out of a total of M transmission antennae and supports a second UE supporting said M (M>N) number of transmission antennae. Said method comprises a step wherein a pilot symbol is placed as an image in the resource block (RB) region on a subframe that enables the transmission of a user-specific pilot symbol to said second UE in a base station; and a step wherein the subframe whereon said pilot symbol has been placed as an image is transmitted, wherein said RB region includes a first region and a second region, and the first region and the second region each include a certain number of continuous OFDM symbols on a respective time axis, and on said first region is placed as an image a cell-specific pilot symbol with respect to the transmission antenna ports 0 to N-1 that can recognize both said first UE and said second UE, and on said second region is placed as an image a user-specific pilot symbol with respect to the transmission antenna ports 0 to M that can recognize said UE only.
