Summary:A method and apparatus for transmitting and receiving signals in a wireless communication system, according to an embodiment of the present invention, may comprise a feature of applying a phase pattern to a wavefront of an optical signal and a feature of transmitting the optical signal. The phase pattern may be determined on the basis of an optical phase shift characteristic of a phase mask, and the phase mask may be determined on the basis of a quantization order and a phase order. Un procédé et un appareil pour transmettre et recevoir des signaux dans un système de communication sans fil, selon un mode de réalisation de la présente invention, peuvent comprendre une caractéristique d'application d'un motif de phase à un front d'onde d'un signal optique et une caractéristique de transmission du signal optique. Le motif de phase peut être déterminé sur la base d'une caractéristique de changement de phase optique d'un masque de phase, et le masque de phase peut être déterminé sur la base d'un ordre de quantification et d'un ordre de phase. 본 발명의 일 실시예에 따른 무선 통신 시스템에서 신호를 송수신하는 방법 및 장치는, 광 신호의 등위상면 (wavefront)에 페이즈 패턴 (phase pattern)을 적용하는 것, 상기 광 신호를 전송하는 것을 포함할 수 있다. 상기 페이즈 패턴은 페이즈 마스크 (phase mask)의 광학적 위상 변환 특성을 기반으로 결정되며, 상기 페이즈 마스크는 양자화 차수 (quantization order) 및 페이즈 차수 (phase order)에 기반하여 결정될 수 있다.
