Apparatus and method for transmitting reference signal in wireless communication system

A method of a base station of a communication system, the method comprising:

• receiving first information associated with a coherence time of a terminal from the terminal;
• determining a reference signal transmission scheme of the terminal, based at least in part on the first information, a number of terminals performing an overlapping transmission, and a frequency resource allocated to the terminal;
• transmitting second information associated with the reference signal transmission scheme to the terminal;
• and
• receiving a reference signal from the terminal,
• wherein the second information includes a transmission start position of the reference signal, a time interval of the reference signal, and a frequency interval of the reference signal.

A terminal of a communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to:
• transmit first information associated with a coherence time of the terminal to a base station,
• receive second information associated with a reference signal transmission scheme from the base station, the second information being determined based at least in part on the first information, a number of terminals performing an overlapping transmission, and a frequency resource allocated to the terminal,
• generate a reference signal, based on the second information, and
• transmit the reference signal to the base station,
• wherein the second information includes a transmission start position of the reference signal, a time interval of the reference signal, and a frequency interval of the reference signal.
