Method and apparatus for transmitting uplink demodulation reference signals

A method of a base station in wireless communication, the method comprising:

• transmitting, to a terminal, information on a comb;
• and
• receiving, from the terminal, demodulation-reference signal (DM-RS),
• wherein the DM-RS is generated based on the information on a comb and the DM-RS is transmitted on transmit power based on the information on a comb.

A terminal in wireless communication, the terminal comprising:

• a transceiver configured to transmit and receive signals;
• and
• a controller coupled to the transceiver and configured to control to:
• receive, from a base station, information on a comb,
• generate demodulation-reference signal (DM-RS) base on the information on a comb,
• determine transmit power of the DM-RS based on the information on a comb, and
• transmit, to the base station, the DM-RS based on the transmit power of the DM-RS.
