The present invention relates to a 5th-generation (5G) or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4th-generation (4G) communication system, such as long term evolution (LTE), and subsequent systems. According to the present invention, a method of a transmitting apparatus includes transmitting, to a receiving apparatus, reference signals through m antenna ports; and transmitting, to the receiving apparatus, the reference signals through n antenna ports, wherein each of the m antenna ports has a first polarization characteristic, each of the n antenna ports has a second polarization characteristic, the m antenna ports are included in a first axis of a two-dimensional space generated based on a vertical axis and a horizontal axis of a uniform planar array (UPA) antenna, and the n antenna ports are included in a second axis of the two-dimensional space.
