Abstract:
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate beyond a 4G communication system such as LTE. Disclosed is a method and apparatus for transmitting or receiving a reference signal in a beamforming communication system. The method comprises the steps of: generating a reference signal sequence for a reference signal that can be used for beam searching; mapping the reference signal sequence to modulation symbols corresponding to resource elements having a predetermined identical subcarrier spacing among resource elements that can be used to transmit the reference signal; generating an OFDM symbol signal including the modulation symbols; and transmitting the OFDM symbol signal using at least one predetermined transmission beam among transmission beams that can be used by a base station.

Claim (Index 14):
The method of  claim 8 ,\n wherein a base station divides a beam search period into a plurality of frame groups which correspond to a number of transmission antennas of the base station, and transmits the OFDM symbol signal through all transmission beams of the base station by the transmission antennas within each frame group, wherein, if a terminal operates in a single input single output (SISO) mode, the terminal receives the OFDM symbol signal during one frame group among the plurality of frame groups to perform a high speed-single beam search, and wherein, if the terminal operates in a multiple input multiple output (MIMO) mode, the terminal receives the OFDM symbol signal during the plurality of frame groups to perform a total beam search for the plurality of transmission beams.
