Abstract
Disclosed are a multi-layer transmission and reception method in a communication system based on 1-bit quantization in a wireless communication system, and an apparatus for supporting same. Particularly, a method by which a first device transmits and receives a signal in a wireless communication system comprises the steps of: receiving a reference signal (RS) from a second device; generating a demodulation reference vector on the basis of the RS; and receiving a data signal from the second device by using the demodulation reference vector, wherein the RS can be generated differently according to the modulation of the data signal.
