Method for transmitting and receiving planar antenna based reference signal in wireless communication system and apparatus therefor

A method in which a base station transmits a signal to a terminal in a wireless communication system is disclosed in the present application. More specifically, the method comprising: generating a terminal specific reference signal sequence for the terminal; The method comprising, based on the vertical sector in which the terminal position, determine the transmission resources for mapping the UE-specific reference signal sequences; The step of mapping the UE-specific reference signal sequence on the determined transmission resources; And characterized by including the step of transmitting using a two-dimensional flat plate antenna for the UE-specific reference signal sequence to the mobile station.
