Method and apparatus for single stream multi-beam transmission and reception in wireless communication system

The present invention relates to a method and apparatus for transmitting and receiving a single data stream into multiple beams in a wireless communication system using a digital pre-coder and the combined hybrid beam forming an analog beam former, of a transmission signal according to an embodiment of the present invention If the control method, for transmitting a transmission signal through a plurality of layers, the method comprising: determining a cyclic shift value to be applied to the transmission signals transmitted through the plurality of layers; The method comprising moving the rotation transmission signals transmitted through the plurality of layers in accordance with the circular motion value; And transmitting by summing the cyclic-shifted transmit signal; may include. According to one embodiment of the invention, it can be adjusted in a hybrid beam forming structure to the same degree as the PA back-off amount to consider the PA back-off amount in a conventional OFDM system. At this time, it may be kept constant irrespective of the average power of the PA input signal to the beam combining multiple beams during a single stream transmission.
