Apparatus and method for transmitting reference signal in wireless communication system

An operating method of a terminal of a wireless communication system, the operating method comprising:

• receiving, from a base station, multiple reference signals including multiple first reference signals corresponding to a first polarization and multiple second reference signals corresponding to a second polarization;
• and
• transmitting, to the base station, feedback information indicating at least one of the multiple reference signals,
• wherein the multiple first reference signals respectively correspond to multiple beams, the multiple second reference signals respectively correspond to the multiple beams, and the second polarization is orthogonal to the first polarization.

A terminal of a wireless communication system, the terminal comprising:

• at least one transceiver;
• and
• at least one processor operatively coupled to the at least one transceiver,
• wherein the at least one processor is configured to:
• receive, from a base station, multiple reference signals including multiple first reference signals corresponding to a first polarization and multiple second reference signals corresponding to a second polarization;
• and
• transmit, to the base station, feedback information indicating at least one of the multiple reference signals,
