Abstract:
A method and apparatus of transmitting a reference signal in a time division duplex (TDD) system is provided. A base station (BS) generates a plurality of demodulation reference signals (DMRSs) for respective layers, maps the plurality of DMRSs to a downlink pilot time slot (DwPTS) region for downlink transmission within a special subframe and transmits the plurality of DMRSs through a plurality of antennas. The special subframe is a subframe for separating uplink and downlink between an uplink (UL) subframe and a downlink (DL) subframe within a frame.
