1. A method for transmitting and receiving a signal by a receiving apparatus in a wireless communication system, the method comprising:
continuously receiving a plurality of reference signals from a transmitting apparatus;
sorting ranges of channel phases based on degrees of phase rotations of the plurality of reference signals received compared to a first received reference signal among the plurality of reference signals;
grouping the ranges of the channel phases into multiple groups, wherein a number of the multiple groups is based on a specific number of bits of data signal to be received;
generating a basis of spatially aggregated phase modulation (SAPM) as a combination of a range of a channel phase from each of the multiple groups;
receiving, from the transmitting apparatus, a data signal with the specific number of bits, wherein each of the bits of the data signal is phase rotated at an interval for a rotation phase unit of the plurality of reference signals; and
decoding the data signal using the basis of the SAPM.
