Abstract
Disclosed is a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as LTE. According to one embodiment of the present invention, a method by which a base station of a wireless communication system using a two-dimensional X-Pol antenna requests feedback information, can comprise the steps of: generating control information for commanding the generation of the feedback information and channel state information (CSI) process information on vertical axes and horizontal axes of a specific planar antenna and respective planar antennas of the two-dimensional X-Pol antenna; transmitting the generated control information to a terminal in the base station; generating and transmitting a reference signal corresponding to the CSI process; and receiving, from at least one terminal, feedback information in correspondence to the number of CSI processes.
