论文摘要
3GPP研究了5G新无线电（NR）作为有效回程的成本效益替代方案的综合访问和回程（IAB）框架。该框架的一个有前途的解决方案是将完整的双工（FD）技术集成，以提高光谱效率并有效利用网络资源所用的FD IAB。但是，FD IAB提出了重大的技术挑战，例如IAB框架中的自我干扰（SI），这可能会对FD IAB的可行性产生怀疑。在本文中，我们简要介绍了FD IAB框架及其支持技术的简要教程。然后，我们通过数值评估并讨论FD IAB的链接级SI降低以及系统级的下行键吞吐性能。最后，我们使用28 GHz硬件原型抑制剂验证了FD IAB的可行性。我们的数值评估和原型测量结果证实，FD IAB是5G NR的有希望的框架。
Integrated access and backhaul (IAB) frameworks for 5G new radio (NR) as a cost-effective alternative to the wired backhaul have been investigated by 3GPP. A promising solution for this framework is the integration of full duplex (FD) technologies to enhance the spectral efficiency and make an efficient use of the network resources-termed FD IAB. However, FD IAB presents significant technical challenges, such as self-interference (SI) in the IAB framework, which may cast doubt over the feasibility of FD IAB. In this article, we present a brief tutorial of the FD IAB framework and its enabling technologies. We then numerically evaluate and discuss the link-level SI reduction and the system-level downlink throughput performance of the FD IAB. Finally, we validate the feasibility of FD IAB using 28 GHz hardware prototype measurements of propagation-domain SI suppression. Our numerical evaluations and prototype measurements confirm that the FD IAB serves as a promising framework for 5G NR.
