摘要： Systems, methods, and apparatuses for phase-rotated reference signals are provided. In accordance with one implementation, phase-rotated reference signals are transmitted from multiple transmit antennas on the same reference signal (RS) resource elements. The receiver may determine channel coefficients for links corresponding to the multiple antennas, based on the received signals at the RS resource elements. Time-domain filtering or frequency-domain orthogonal codes may be used to determine the channel coefficients for links corresponding to the multiple antennas. The phase-rotation information may be broadcasted in a system information block (SIB) message or signaled in a radio resource control (RRC) message.
