摘要

在这封信中，我们提出了一种共生非正交多址接入（NOMA）相辅相成的绿色海量接入范式，以更好地满足物联网多样化和具有挑战性的要求。其中，反向散射设备（BD）利用传统用户的相同频谱资源进行反射，同时提供有益的多径以提高传统传输的性能。我们的目标是联合优化主动/接收波束成形矢量和反射系数，以最大限度地提高加权和率，并通过开发的分析结果证明无需为 BD 设计专用波束。仿真结果验证了共生 NOMA 方案的优越性。

Symbiotic NOMA: A Mutualism Communication Paradigm Toward Green Massive Access

In this letter, we propose a symbiotic non-orthogonal multiple access (NOMA) mutually reinforcing paradigm for green massive access to better meet the diverse and challenging requirements of Internet-of-Things. In particular, the backscatter device (BD) utilizes the same spectrum resources of the legacy users for reflection while providing beneficial multipath to enhance the performance of legacy transmission. We aim to jointly optimize the active/receive beamforming vectors and reflection coefficients to maximize the weighted sum rate, proving that there is no need to design a dedicated beam for BD via the developed analytical results. Simulation results validate the superiority of the symbiotic NOMA scheme.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
