Abstract:
A method for transmitting a pilot signal in a downlink MIMO (Multi Input Multi Output) supporting multiple transmission antenna is disclosed. The method includes transmitting a subframe to which cell-specific pilot symbols and User Equipment-specific (UE-specific) pilot symbols are mapped, in which the cell-specific pilot symbols are mapped to a first region of the subframe and the UE-specific pilot symbols are mapped to a second region of the subframe.
