Abstract: A method for a transmitter of a mobile communication system transmitting and receiving signals according to an embodiment of the present specification comprises the steps of: transmitting to a receiver system information for transmitting a signal to the receiver including a connection between a wireless resource and a transmitting antenna; transmitting a reference signal to the receiver based on the system information; and receiving from the receiver feedback information generated based on the reference signal. According to an embodiment of the present specification, in a beamforming transmission method of a mobile communication system, a transmitter can determine whether to perform digital pre-coding without advance information from a receiver and can consequently perform a transmission, and can thereby perform lower-overhead and efficient signal transmission/reception.
