5G는 전 세계적으로 대규모 상용화를 달성했으며, 글로벌 6G 연구개발도 가속화되고 있다. 더 많은 새로운 사용 사례를 지원하려면 6G 이동통신 시스템은 5G를 훨씬 뛰어넘는 극한의 성능 요구 사항을 충족해야 합니다. 물리계층 핵심기술은 각 세대 이동통신 시스템 진화의 근간이 되며, 이중 이중화, 파형, 다중접속 6대 핵심기술은 각 세대 이동통신 시스템의 대표적인 특징이다. 본 논문에서는 세 가지 핵심 기술의 개발 이력과 동향을 체계적으로 검토하고, NOD(Non-Orthogonal Duplex), NOMA(Non-Orthogonal Multiple Access) 및 6G를 위한 NOPHY(Non-Orthogonal Physical Layer) 개념을 정의합니다. 비직교 파형(NOW). 먼저, 용량 확보와 구현 복잡성의 관점에서 NOPHY의 필요성과 타당성을 분석합니다. 그런 다음 NOD, NOMA 및 NOW의 최근 진행 상황에 대해 논의하고 여러 후보 기술과 잠재적인 성능 향상을 강조합니다. 마지막으로 6G의 새로운 트렌드와 결합하여 성능과 유연성의 균형을 잘 맞추는 NOPHY 기반의 통합 물리 계층 설계를 제시하고, XNUMXG 물리 계층 핵심 기술의 연구 개발이 가능한 방향을 제시합니다.

Abstract: 5G has achieved large-scale commercialization across the world and the global 6G research and development is accelerating. To support more new use cases, 6G mobile communication systems should satisfy extreme performance requirements far beyond 5G. The physical layer key technologies are the basis of the evolution of mobile communication systems of each generation, among which three key technologies, i.e., duplex, waveform and multiple access, are the iconic characteristics of mobile communication systems of each generation. In this paper, we systematically review the development history and trend of the three key technologies and define the Non-Orthogonal Physical Layer (NOPHY) concept for 6G, including Non-Orthogonal Duplex (NOD), Non-Orthogonal Multiple Access (NOMA) and Non-Orthogonal Waveform (NOW). Firstly, we analyze the necessity and feasibility of NOPHY from the perspective of capacity gain and implementation complexity. Then we discuss the recent progress of NOD, NOMA and NOW, and highlight several candidate technologies and their potential performance gain. Finally, combined with the new trend of 6G, we put forward a unified physical layer design based on NOPHY that well balances performance against flexibility, and point out the possible direction for the research and development of 6G physical layer key technologies.
