标题： Signal Processing and Learning for Next Generation Multiple Access in 6G

摘要： 无线通信系统到目前为止主要依赖于资源的正交性来促进设计和实现，从用户接入到数据传输。 第六代（6G）无线系统中的新兴应用和场景将需要大量的连接和大量数据的传输，这要求在设计概念上更加灵活，超越正交性。 此外，信号处理和学习的最新进展引起了广泛关注，因为它们为许多领域中以前难以解决的复杂信号处理问题提供了有前途的解决方案。 本文综述了迄今为止在下一代多址接入的信号处理和学习领域的研究努力，重点放在大规模随机接入和非正交多址接入上。 讨论了与新技术的有前景的相互作用以及基于学习的NGMA面临的挑战。 显示英文摘要

摘要： Wireless communication systems to date primarily rely on the orthogonality of resources to facilitate the design and implementation, from user access to data transmission. Emerging applications and scenarios in the sixth generation (6G) wireless systems will require massive connectivity and transmission of a deluge of data, which calls for more flexibility in the design concept that goes beyond orthogonality. Furthermore, recent advances in signal processing and learning have attracted considerable attention, as they provide promising approaches to various complex and previously intractable problems of signal processing in many fields. This article provides an overview of research efforts to date in the field of signal processing and learning for next-generation multiple access, with an emphasis on massive random access and non-orthogonal multiple access. The promising interplay with new technologies and the challenges in learning-based NGMA are discussed.
