摘要:

集成接入和回程(IAB)正在被研究作为通过实现无线回程链路来中继接入业务来克服超密集5G毫米波(mmWave)网络的部署成本的手段。然而,对于这些系统的开发,通过端到端系统级仿真来验证IAB在现实场景中的性能是至关重要的。在本文中,我们阐明了IAB的最新标准化活动,并比较了在毫米波部署中使用和不使用IAB的架构。虽然很好地理解,IAB网络通过避免需要提供有线回程到每个蜂窝基站降低部署成本,在本文中,我们证明了IAB使用端到端系统级仿真提供的小区边缘吞吐量优势。我们进一步强调了一些与此架构相关的研究挑战,需要进一步调查。

英文摘要:

Integrated Access and Backhaul (IAB) is being investigated as a means to overcome deployment costs of ultra-dense 5G millimeter wave (mmWave) networks by realizing wireless backhaul links to relay the access traffic. For the development of these systems, however, it is fundamental to validate the performance of IAB in realistic scenarios through end-to-end system level simulations. In this paper, we shed light on the most recent standardization activities on IAB, and compare architectures with and without IAB in mmWave deployments. While it is well understood that IAB networks reduce deployment costs by obviating the need to provide wired backhaul to each cellular base-station, in this paper we demonstrate the cell-edge throughput advantage offered by IAB using end-to-end system level simulations. We further highlight some research challenges associated with this architecture that will require further investigations.
