    摘要: The present invention relates to a method for transmitting pilot signals in a downlink multiple-input multi-output (MIMO) system which supports a first user equipment (UE) for supporting an N number of transmitter antennas from among a total M number of transmitter antennas, and a second UE for supporting said M (wherein, M>N) number of transmitter antennas. The method comprises the steps of: enabling a base station to map pilot symbols in a resource block (RB) on a subframe for transmitting user-specific pilot symbols which can be recognized only by the second UE; and enabling the base station to transmit the subframe in which the pilot symbols are mapped. The cell-specific pilot symbols for transmitter antenna port 0 to N−1, which can be recognized by both the first UE and the second UE, and the user specific pilot symbols for transmitter antenna ports N to M−1, which can be recognized only by the second UE, are mapped in the allocated resource block.

    摘要: A method and apparatus of transmitting a reference signal in a wireless communication system is provided. Demodulation Reference Signals (DMRSs) for a plurality of respective antennas is generated. The DMRSs are mapped to a resource region, and transmitted through the respective corresponding antennas. The DMRSs are multiplexed using at least one of frequency division multiplexing (FDM), code division multiplexing (CDM), and time division multiplexing (TDM) methods and mapped in the resource region. Also, a position of an orthogonal frequency division multiplexing (OFDM) symbol to which the DMRSs are mapped in the resource region is an OFDM symbol to which a physical downlink control channel (PDCCH) and a legacy cell-specific reference signal (CRS) are not mapped.
